論文

  • Practical Method for Identifying Model Parameters for Machining Error Simulation in End Milling Through Sensor-Less Monitoring and On-Machine Measurement
    Kazuki Kaneko; Arisa Kudo; Takanori Waizumi; Jun Shimizu; Libo Zhou; Hirotaka Ojima; Teppei Onuki, Depending on cutting conditions, unacceptable machining errors are caused by tool deflection in end milling operations. Many studies have proposed methods for predicting the machining error owing to the tool deflection to achieve the theoretical optimization of the cutting conditions. However, the conventional machining error simulation is not practically utilized to determine the optimal cutting conditions. Tool system stiffness parameters and cutting coefficients must be identified in advance to simulate machining errors. However, dynamometers and displacement sensors are required for parameter identification. Therefore, it is impossible to identify the required parameters in typical factories, which do not possess such special equipment. In this study, a practical method was developed to identify the stiffness parameters that can be determined in factories. The proposed method employs on-machine measurement and sensor-less cutting force monitoring to achieve practical parameter identification. In the proposed method, the profile milling is first conducted. During the milling operation, the cutting force and cutting torque are monitored through a controller based on the sensor-less monitoring technique. After the operation, the machining error distribution on the machined surface is measured on machine using a touch probe. The required parameters are identified by minimizing the differences between the measured and theoretical forces, torques, and machining error distributions., Fuji Technology Press Ltd.

  • Study on the finishing capability and abrasives-sapphire interaction in dry chemo-mechanical-grinding (CMG) process
    Ke Wu; Libo Zhou; Teppei Onuki; Jun Shimizu; Takeyuki Yamamoto; Julong Yuan, Chemo-mechanical-grinding (CMG) is a fixed abrasive process by integrating both chemical reaction and mechanical grinding. This paper targets on studying the finishing ability of dry CMG processes for mono-crystal sapphire and understanding the underlying abrasives-sapphire interaction. The experiment results suggest that dry CMG processes by applying either Cr2O3 or SiO2 are able to produce sapphire substrate with an excellent surface quality and subsurface integrity, meanwhile, maintain the geometric accuracy. The underlying abrasives-sapphire interaction termed as solid phase reaction is demonstrated by X-ray photoelectron spectroscope (XPS) analysis. It is suggested that Cr2O3 abrasives is more chemically active against sapphire (Al2O3) when compared with SiO2 abrasives. Combined with a higher mechanical effect provided by Cr2O3 abrasives, the finishing efficiency of Cr2O3 abrasives is almost 2 times higher than traditional SiO2 abrasives. The subsurface integrity characterization by using Raman microscope and transmission electron microscope reveals that Cr2O3 abrasives introduces a shallow damage layer (about 100 nm) on the top surface of sapphire substrate since the chemical effect is not sufficient enough to meet the balance with mechanical effect. With a better mechanical-chemical balance achieved by SiO2 abrasives, a damage free subsurface is obtained. Therefore, besides of traditional SiO2 abrasives, Cr2O3 abrasives is suggested to be another potential candidate for finishing sapphire substrate., Elsevier Inc.

  • The development of hybrid-feed system and technology of CFRP machining
    Daisuke Takenouchi; Hirotaka Ojima; Libo Zhou; Teppei Onuki; Jun Shimizu, The main machining process for CFRP is hole drilling. Due to the composite structure and high strength of the material, the drilling process counter some major problems such as burrs, delamination and tool life. Therefore, in this study, we aim to realize a hybrid feed mechanism with constant pressure and constant speed feed. This mechanism changes the machining pressure according to the progress of machining without overloading and delamination of CFRP. In addition, by applying ultrasonic vibration, chip transportation is increased and tool friction with chips is reduced. In this paper, we developed a highly accurate CFRP processing machine is equipped with a hybrid mechanism ultrasonic vibration. The efficiency of developed processing machine is evaluated by practical experiment., Japan Society of Mechanical Engineers

  • Theoretical analysis on effects of grain size variation
    Libo Zhou; Yutaro Ebina; Ke Wu; Jun Shimizu; Teppei Onuki; Hirotaka Ojima, Grinding wheels consist of abrasive grains, bonding materials and porous, which are specified by five factors; type of grain, size of grain, bonding material, bonding strength and grain concentration or volume fraction of grain. The grain size is represented by the mean diameter/radius of grains. However, the abrasives in a grinding wheel are randomly scraggly in size and shape. There is no particular aspect to regulate the variation in grain size. This paper addresses, via a theoretical analysis on the distribution of grain size, the average volume of a grain, the number of grains contained in a specific volume of the wheel, the number and protrusion distribution of grains exposed in a wheel working surface and the fraction of effective grain, when the grain size varies. The effect on the resultant finished surface roughness is also discussed. (C) 2017 Elsevier Inc. All rights reserved., ELSEVIER SCIENCE INC

  • Study on the potential of chemo-mechanical-grinding (CMG) process of sapphire wafer
    Ke Wu; Libo Zhou; Jun Shimizu; Teppei Onuki; Takeyuki Yamamoto; Hirotaka Ojima; Julong Yuan, Chemo-mechanical-grinding (CMG) is a hybrid process which integrates chemical reaction and mechanical grinding between abrasives and workpiece into one process. It has been successfully applied into manufacturing process of silicon wafers where both geometric accuracy and surface quality are required. This paper aims to study the potential of CMG process in manufacturing process of single crystal sapphire wafers. The basic material removal mechanism in terms of chemical effect and mechanical effect in CMG process has been analysed based on experiment results of two different kinds of CMG wheels. The experiment results suggest that chromium oxide (Cr2O3) performs better than silica (SiO2) in both material removal rate (MRR) and surface quality. It also reveals that, no matter under dry condition or wet condition, CMG is with potential to achieve excellent surface quality and impressive geometric accuracy of sapphire wafer. Meanwhile, test result by Raman spectrum shows that, by using Cr2O3 as abrasive, the sub-surface damage of sapphire wafer is hardly to be detected. Transmission electron microscopy (TEM) tells that the sub-surface damage, about less than 50 nm, might remain on the top surface if chemical effect is not sufficient enough to meet the balance with mechanical effect in CMG process., SPRINGER LONDON LTD

  • シリコンウェハ変形による加工変質層残留応力の評価
    髙橋清樹,周 立波,清水 淳, Diamond grinding is often used for silicon wafer thinning. This process brings about not only efficient material removal of wafer, but also the subsurface damage which is accompanied by residual stress on the wafer surface. The residual stress greatly contributes to the distortion of thin wafer. Reported in this paper are deflection behavior of wafer when it is subjected to the residual stress and a practical method of the residual stress estimation based on the wafer deflection. Based on the numerical FEM analysis results, the thin wafer is found to undergo three stages of deformation, dependent on the quantity of residual stress. When the residual stress is sufficiently small, the wafer is deflected into a sphere shape which is able to be described by the Stoney's Equation with its corrective coefficient. With an increase in the residual stress, the wafer deflection starts to depart from the sphere shape, but still maintains in axisymmetric form until the deflection reach to 1 ~ 2 times larger than the wafer thickness. Beyond this critical point, the shape of deflected wafer is transformed into a cylindrical warping. The amount of wafer deflection is then associated to the residual stress to provide an easy way of estimation for residual stress on wafer with different thickness., 精密工学会

  • 定在波音場を用いた産業廃棄物分別方法の開発
    稲田智広,周 立波,尾嶌裕隆,清水 淳,

    In recent years, more than 10 million tons of industrial wastes are discarded annually. Those wastes are mainly composed of plastic, glass and metals which are the materials massively used in automobiles, electric and electronic products. It is well known that industrial waste contain precious metals like gold and have a great value of reutilization. Therefore, technology to properly separate the waste by their types of subject is very important for recycling industry. In this study, we have developed a new separation method by use of acoustic levitation phenomenon in a standing wave field. Unlike the conventional methods such as centrifugal particle separation or magnetic separation, this method enables to sort subjects by their densities, without relying on other material properties including size, magnetism and weight. First described in this paper is a theoretical analysis of levitation force exerted on an object to derive its trajectory in a standing wave field. It is found that the motion of the object is governed by its density and the strength of acoustic field. Based on this finding, we developed a prototype of separation system with twin-transducers and a belt conveyer. As a result of test to separate a mixture of SiO2 and Fe particles, 62wt% SiO2 is captured at node side while 72wt% Fe is captured at anti-node side. Finally, the prototype is used to repeatedly separate the chipped waste of actual OA equipment. Its density was increased about 150%.

  • Study on grinding of LiTaO3 wafer using effective cooling and electrolyte solution
    Wei Hang; Libo Zhou; Kehua Zhang; Jun Shimizu; Julong Yuan, As a typical multi-functional single crystal material, lithium tantalate (LiTaO3 or LT) exhibits its excellent electro-optical, piezoelectric properties and has now been widely applied into many applications, such as electro-optical modulators, pyroelectric detectors, optical waveguide, piezoelectric transducers and SAW (surface acoustic wave) substrates. LT is known as a very important functional material, however the details of its machinability are not readily available yet. The content in this study is firstly focuses on the physical properties of LT like piezoelectric and pyroelectric effects and their influence on grinding performance. The obtained results are analyzed and discussed to understand its physical properties which have significant influences on their machinability in the grinding process. The crack initiation is possible to be dominated by internal stress which originated from self-polarization of the material itself. Hence, in order to suppress the physical effects induced by polarization during grinding of LT, control the temperature of coolant and increase the electrical conductivity of coolant are purposely tried in this study. The grinding results suggest that control of coolant temperature and use of electrolyte solution can effectively suppress the increasing rate of grinding torque and surface roughness, which in turn enhance the performance of LT wafer grinding. The LT wafers are eventually able to be thinned less than 100 mu m. (C) 2015 Elsevier Inc. All rights reserved., ELSEVIER SCIENCE INC

  • Molecular dynamics simulation of sliding process considering experimental results of nanocontact and influence of oxide film               
    Jun Shimizu; Libo Zhou; Teppei Onuki; Hirotaka Ojima; Hirotaka Miwa; Toshikazu Nanbu, In order to clarify the sliding friction phenomena between a diamond slider and a copper specimen in the air, a series of the molecular dynamics simulations and the friction experiments using a friction force microscope were examined. In the simulation model, both the adhesion effects obtained through the nanocontact experiments in the air and the effects of the oxide film generated in the uppermost specimen surface were considered by using a simple method with just controlling the dissociation energy in the Morse potential function. From the comparisons between the simulation and the experimental results, it is confirmed that they have a good similarities in the friction coefficient, in particular, in its sudden increase when the oxide film is broken by wear. The breaking mechanism of the oxide film originating from the relatively higher hardness of the oxide film is also clarified by observing the slip deformation state of the copper specimen., Japanese Society of Tribologists

  • Machining quality controls in ultrashort pulse laser micromachining on lithium niobate substrates
    Teppei ONUKI; Hirotaka OJIMA; Jun SHIMIZU; Libo ZHOU; Itaru TAKAHAMA; Kazuki KAMOSHIDA, The physical relations between the machining conditions and the surface qualities of machined surfaces are investigated in laser micromachining (direct drawing) on ferroelectric lithium niobate (LN), for high quality fabrication of microstructures on the functional material with brittle nature, as a future manufacturing technology of advanced MEMS devices. Pico second pulsed laser with the wavelength of 1064nm was used, then multiphoton process dominants the laser-matter energy coupling for material removal and generating heat. Quantity of heat was controlled by the energy density ρ(0.1-10 J/cm^2), the pulse shot number N(1-1000), the pulse interval t(0.5-10 msec), the kurtosis of laser spot k(14-22), and the environment (air or water). Heat energy is increased exponentially by ρ, and additively by the pulse shot number N. Hence high quality surfaces are obtained by conditions as low ρ-high N of laser irradiations even the same laser fluence ρ×N. Also, longer t(as cooling periods), lower k(as uniform laser power in the spot) and underwater processing (as hear dissipative medium) are effective for high machining quality., JSME

  • SiウエハのChemo-Mechanical-Grinding(CMG)に関する研究:—第3報:砥石に含まれる塩基の作用の解明と砥石物性値の最適化によるCMGの確立—
    田代 芳章; 周 立波; 清水 淳; 篠田 知顕; 三上 祐樹, In semiconductor industry, production of ever flatter, thinner and larger Si wafer are required to fulfill the demands in high integration and cost reduction. A severe problem encountered in wafer thinning process is the warp and distortion of wafer induced by the residual stress and subsurface damage. Chemo-mechanical grinding (CMG) process is emerging process which combines the advantages of fixed abrasive machining and chemical mechanical polishing (CMP), offers a potential alternative for stress relief. However, since the sodium carbonate is used as additives in previously developed CMG wheels, the metal ions like sodium ion were possibly introduced on the machined wafer surface, and could risk in metal contaminations. In order to develop the high quality CMG wheel excluding sodium carbonate, CMG wheels with different recipe were developed. So far, CMG has been studied to investigate the effects of wheel geometry and grinding conditions on the removal rate, and effects of bond materials and additives on the surface quality in our previous researches. In this study, the focus was given to the wheel mechanical property (bending strength, elastic modulus) of CMG wheels. The difference in wheel properties is discussed by association with CMG performance including wheel wear and surface roughness. The result have demonstrated that the surface roughness of newly developed CMG silicon wafer is equivalent to that of CMG containing sodium carbonate as additive silicon wafer without any grinding marks., 公益社団法人 精密工学会

  • Process study on large-size silicon wafer grinding by using a small-diameter wheel
    Yutaro Ebina; Tomoya Yoshimatsu; Libo Zhou; Jun Shimizu; Teppei Onuki; Hirotaka Ojima, Silicon (Si) is a fundamental material in the semiconductor industry. The advancement of semiconductor devices have offered convenience and comfort to our life. In order to raise productivity and economic efficiency, the semiconductor industry keeps looking for use of larger size Si wafers. The next generation wafer is expected to be sized as large as 450 mm in diameter. Many wafering processes including lapping, grinding and polishing have been studied and grinding technology stands out as the most promising process for large-size Si wafer manufacturing. In the current in-feed grinding scheme adopted for Si wafers, the wheel diameter used is generally equal to or larger than the wafer diameter. In turn, larger diameter wheels require larger size machine tools and production lines, which lead to increase in manufacturing costs. In this paper, both experiment and kinematical analysis have been carried out to investigate the feasibility of using small diameter grinding wheels to grind large size Si wafers, mainly focusing on the effects of wheel diameter on wafer geometry and surface roughness. The results show that both wheels generated a central convex profile on the wafer and the small wheel achieved a slightly better flatness than the large wheel. The surface roughness were similar one to another for most area of the wafer except the fringe around its edge. All these experimental results were predicable by the kinematic model established in this paper. Particularly, the kinematic analysis found that the cutting path made by small wheel with diameter equaling to the wafer radius was parallel each other at the fringe around wafer edge, which directly worsened the surface roughness., JAPAN SOC MECHANICAL ENGINEERS

  • Modeling of process mechanisms in pulsed laser micro machining on lithium niobate substrates
    Teppei Onuki; Ippei Murayama; Hirotaka Ojima; Jun Shimizu; Libo Zhou, The mechanism behind the laser ablation of LN is investigated using near infrared pico-second-pulsed laser. A model of the mechanism is developed, deriving the mechanical, thermal, and photonic properties of LN in addition to doing preliminary experiments on laser ablation with controlled laser fluence. β is material removal using the nonthermal process via multiphoton ionization, γ is nonthermal material removal with chipping or cracking produced by generated heat (but at temperatures below the melting point), and δ is material removal using the thermal process with temperatures above the melting point, resulting in resolidification at the surface and the adhesion of oncemolten burrs around the processed area. In a process modes map constructed through exhaustive experiments on laser ablation under various irradiation conditions (at specific energy ρ and with number of pulse shots N′), different contributions of ρ and N′ in the machining process are found. In terms of machining quality, desirable conditions in the control of laser irradiations are the use of weaker ρ and increased N′ to keep thermal damage to a minimum and to raise the removal rate., Fuji Technology Press

  • Development of metal cutting process accompanied by a localized compressive hydrostatic stress field formation: Examination by molecular dynamics simulation
    Keito Uezaki; Jun Shimizu; Libo Zhou, Improving machined surface integrity is important for precision machining. The aim of this work is to develop a cutting tool, which enables to generate a localized compressive hydrostatic stress field in the vicinity of cutting point to suppress unnecessary plastic flow and to improve the surface integrity of workpiece. In this paper, as the first step a simple cutting tool attached with a laminar jig equipped with a small rectangular hole for cutting chip elimination was proposed, and a molecular dynamics simulation of nano-cutting of monocrystalline aluminum was performed in order to verify and reveal the effectiveness and issues, respectively, of proposed method for improving machined surface integrity. The obtained simulation results were also compared to those using a normal cutting tool in order to clarify the cutting mechanism. As a result, it was clarified that a high compressive hydrostatic stress field was successfully introduced in the vicinity of cutting point. Consequently, the burr formation and elimination of cutting chip were remarkably suppressed and smoothened, respectively by using proposed cutting tool. (C) 2013 Elsevier Inc.

  • Wafer grinding of using fixed abrasive diamond wheel - Evaluation of cutting edge distribution in diamond wheels
    Yutaro Ebina; Li Bo Zhou; Jun Shimizu; Teppei Onuki; Hirotaka Ojima, The wafer grinding by use of fixed abrasive diamond wheels is required to create a high-quality wafer surface in a short time. In general, it is known that the grinding performance of diamond wheel is mainly dependent on grinding wheel specifications and grinding conditions. The cutting edge distribution or abrasive protrusion height in depth-wise of a specified wheel is one of the most important factors to determine the finishing surface roughness and the grinding force, which in turn determine the surface and subsurface quality of ground wafers. The overall purpose of this study is to understand the dynamic behavior of each diamond abrasive via modeling an actual diamond wheel and simulating of wafer grinding. In previous report [1], we have theoretically analyzed three-dimensional cutting edge distribution on the working surface of diamond wheels. This paper reports our recent achievements in the evaluation of 3-D cutting edge distribution in depth-wise of a specified wheel via the bearing ratio of its topography., Trans Tech Publications Ltd

  • Development of non-contact classifying systems by use of acoustic levitation
    Tomohiro Inada; Libo Zhou; Jun Shimizu; Hirotaka Ojima; Takuya Ito, The phenomenon that bubbles or particles are suspended at the node position of a standing wave of sound is known as acoustic levitation and has recently been applied in the fields of semiconductors, aerospace, and biology [1-3]. By using this phenomenon in this study, a new classification method has been proposed, and a device has been developed to sort objects in accordance with their densities. Unlike the conventional methods as such as centrifugal particle separation or magnetic separation, this method can separate fine particles both of metal and non-metal and without contact easily only using acoustic power. First, we derived the acoustic radiation pressure to be applied to the object from King’s theory, and then we designed and developed a twin-transducer system to apply the required levitation force. The distributions of sound pressure and particle velocity were then visualized. Finally, a series of experiments was conducted to show the capability of classifying the fine abrasive SiO2 particles and fine iron particles (f = 50 μm)., Trans Tech Publications Ltd

  • Influence of surface integrity in silicon wafer thickness measurements by reflection spectroscopy
    Teppei Onuki; Ryusuke Ono; Hirotaka Ojima; Jun Shimizu; Li Bo Zhou, Wafer thickness meter by reflection spectroscopy is used for on-site thickness inspections in wafer thinning process, because of its excellent properties as high measurement accuracy in very thin wafers inspections by non-contact sensing. In practice, ground surfaces are not ideal flat surfaces. Thus the spectra suffers influences of the surface roughness and the waviness, as modifying spectral features by optical diffusion, and as decreasing the reflection received by dispersion of propagating directivity. In this paper, we investigate how the surface integrities of ground wafer surfaces are involved in the thickness measurements by both theoretical and experimental approach, to investigate the requirements in sample conditions and to guarantee the accuracy of the measurements., Trans Tech Publications Ltd

    Yoshiaki TASHIRO; Libo ZHOU; Jun SHIMIZU; Noriaki SHINODA; Yoshinori MITSUI, Free abrasive machining has been widely used for the finishing of mono-crystallined sapphire wafers. There are, however, critical issues remaining, such as degradation of flatness due to the nature of pressure controlled in-feed dynamics, environmental load due to disposal of wasted slurry, and time/cost consuming. Fixed abrasive machining is one of the potential alternatives to make a breakthrough to such problems.

  • A robust procedure of data analysis for micro/nano indentation
    Wei Hang; Libo Zhou; Jun Shimizu; Julong Yuan, This paper reported a robust procedure of data processing in micro/nano indentation for determining the elastic modulus and hardness. As both elastic modulus and indentation hardness strongly depend on the contact stiffness, the contact area and the accuracy with which they are determined, described in the first part of this paper was a comparison of three approaches to estimate the Contact stiffness. From the experimental results, it is concluded that the contact stiffness computed from the curve fitting method is most reliable and robust. Subsequently in the second part of this paper, a new procedure for computation of the contact area was proposed by use of multivariable estimation via a least square fitting. In the final part of this paper, indentation tests on silicon and aluminum alloy were conducted to verify that the proposed procedure is not only valid for a variety of materials from hard-brittle to soft-ductile, but also robust and applicable to indenters with imperfect geometry.

  • Development of finishing system using acoustically levitated abrasive
    Tomohiro Inada; Libo Zhou; Hirotaka Ojima; Jun Shimizu, Based on the acoustic levitation phenomenon, we propose and develop an acoustic levitation / positioning system to control the movements of free abrasives to finish inner surfaces. Described in this paper are the theoretical analysis of levitation forces generated in a standing wave field and the results of experiments involving levitation and positioning. We first calculate the wave amplitude and frequency required to levitate the abrasives. Based on the results, we develop a system consisting of a sound transducer (speaker), a reflector (an aluminum plate), an amplifier, and a function generator, and we successfully not only levitate but also position actual abrasives in a tube. We find that the relation between the size and density of the abrasives and the strength of the acoustic field (wave amplitude and frequency) basically agree with the theoretical prediction. In addition, the kinetics of levitated abrasives, including their positions and movements, are precisely controlled by varying the wave frequency and switching from one node position to another., Fuji Technology Press

  • Study on thermal influence of grinding process on LiTaO3
    Wei Hang; Libo Zhou; Jun Shimizu; Julong Yuan, As a typical multi-functional single crystal material, Lithium tantalate (LiTaO3 or LT) exhibits its excellent electro-optical, pyroelectric and piezoelectric properties, and has now been widely applied into many applications, especially in the telecommunication field. However, the most critical issue in the process is its pyroelectric effect and piezoelectric effect which potentially leads to crack initiation during grinding. Because it is rich in plasticity, LT demands larger specific energy for material removal. As the most machining energy is eventually converted into heat, LT undergoes a rapid rise in temperature during the grinding process, thus highly risks in thermal shock. In order to clarify the thermal influence on the grinding process of LiTaO3, the effects of coolant temperature, diamond grinding wheel geometry and material of substrate are investigated in this research. The experimental results show that the increasing rate of grinding torque (or force) and surface roughness are two major factors dominating the crack initiation during grinding of LT wafers. Via a DOE (design of experiment) analysis, coolant temperature and wheel type stand out as the main factors influencing on the increasing rate and wafer surface roughness., TRANS TECH PUBLICATIONS LTD

A Fourier transform near infrared (FT-NIR) spectrometer with indium gallium arsenide was used in the developed system. As a result of the sensitiveness in the whole near infrared band and high spectral resolution united with high signal noise ratio of the FT-NIR spectrometer, the maximum measurable thickness is improved to 88 mu m while sub-micron order of the minimum measurable thickness is also improved., TRANS TECH PUBLICATIONS LTD

  • Fabrication of Surface Microtexture by Vibration Assisted Cutting
    Jun Shimizu; Takeyuki Yamamoto; Libo Zhou; Hirotaka Ojima; Teppei Onuki; Shun-ichi Nagaoka, Improving materials surface function by introducing nano/micro surface textures is of great interest in various fields. The authors have also achieved an improvement in the photocatalytic surface function by introducing the microcutting grooves texture on the titanium dioxide surfaces. In this report, the authors performed the vibration assisted cutting to fabricate finer surface microtextures anticipating future usage as microtexture moulds for the nanoimprinting and/or injection moulding. In the experiment, a pure copper plate was cut using a sharply pointed triangular diamond tip vibrated by a fast tool servo system in the direction of cutting depth with pm order amplitude and kHz order frequency. As a result, it was found that the periodical micro concave-convex patterns with the combinations of impressions and pileups can be obtained by the proposed method using almost the same vibration amplitude as the cutting depth. It was also achieved that a micro-textured surface with numerous concave-convex patterns less than 1 pan in height with 3 pm in pitch., TRANS TECH PUBLICATIONS LTD

  • Molecular dynamics simulation of energy dissipation process in atomic-scale stick-slip phenomenon
    Jun Shimizu; Libo Zhou; Takeyuki Yamamoto, A molecular dynamics simulation is performed to clarify the energy dissipation process in the atomic-scale friction, particularly with the two-dimensional atomic-scale stick-slip phenomenon as observed in the friction experiment by AFM/FFM. In the present simulation, a well defined Cu{1 0 0} surface is scanned in the direction of 〈1 0 0〉 with different scan position by a carbon atom probe using a simple model where the effect of cantilever stiffness of the atomic force microscope is taken into consideration. From the simulation results, it is clarified that the dissipated mechanical energy thorough the one or two-dimensional atomic-scale stick-slip phenomenon can be calculated more precisely from the stored elastic energy using the amplitude of stick-slip force signal in each direction than the work calculated using the average friction force.

  • Study on the mechanical properties of lithium tantalate and the influence on its machinability
    Wei Hang; Libo Zhou; Jun Shimizu; Julong Yuan; Takeyuki Yamamoto, As a typical multi-functional single crystal material, lithium tantalate (LiTaO3 or LT) exhibits its excellent electro-optical, piezoelectric properties and has now found many applications, such as electro-optical modulators, pyroelectric detectors, optical waveguide, piezoelectric transducers and SAW (Surface Acoustic Wave) substrates. Although LT is known as a very brittle material, however, detailed summaries of its mechanical properties and machinability are not readily available yet. In order to clarify and understand the fundamental mechanical properties of LT, micro/nano indentation tests are conducted in this study to evaluate elastic modulus, hardness and fracture toughness. Other two typical single crystals of silicon and sapphire are chosen for comparison. The obtained results are analyzed and discussed to understand their behaviors in elastic, plastic (ductile) and brittle regimes, and the influences on their machinability in the machining process., Fuji Technology Press

  • Molecular Dynamics Simulation of Metal Cutting with Local Hydrostatic Pressure Field Formation
    Keito Uezaki; Jun Shimizu; Libo Zhou; Teppei Onuki; Hirotaka Ojima, Improving machined surface integrity is one of the important issues in the precision machining. This study aims to develop a cutting tool, which enables to generate a local hydrostatic pressure field in the vicinity of the cutting point to suppress the extra plastic flow in the workpiece, because it is known that materials including metals never cause plastic flow and fracture no matter how much greater hydrostatic pressure field is given. In this paper, a simple cutting tool with planer jig is proposed and a molecular dynamics simulation of cutting is performed as the first step. As a result, it is confirmed that the reduction of the plastic deformation, mainly in the burr formation become remarkable with the proposed model due to the suppression of extra side plastic flow, and relatively high-hydrostatic stress field is formed in the vicinity of cutting point. However, it is also observed that relatively many dislocations are generated beneath the cutting groove., TRANSACTION PUBLISHERS

  • Study on grinding processing of sapphire wafer
    Yutaro Ebina; Wei Hang; Libo Zhou; Jun Shimizu; Onuki Teppei; Hirotaka Ojima; Yoshiaki Tashiro, This paper reports our recent results on the diamond grinding process of single crystallized sapphire wafers. It was found that the diamond grains were severely dislodged at the wheel/workpiece interface and the material was removed by a mixed process of both grinding and lapping. Grinding governed the wafer center while lapping dominated its fringe. By increasing the wheel speed, it was able to shift the dominant process from lapping to grinding, and achieve a better surface roughness. Nine diamond wheels varying in both concentration and bond material were tested in surface grinding of 6 inch sapphire wafer, to investigate the dynamic behavior of diamond grain in the grinding process and its resultant surface quality and productivity., TRANS TECH PUBLICATIONS LTD

  • Research on digital filters for Si wafer surface profile measurement - Design of filters by total variation
    Hirotaka Ojima; Kazutaka Nonomura; Libo Zhou; Jun Shimizu; Teppei Onuki, The underlying data form of a wafer is a matrix of length (or height) measurements. In the presence of noise, evaluation parameters are normally biased. The expectation value such as peak-to-valley and GBIR (global backside ideal range) is systematically larger than the "true" value. Correction and compensation need a large population of measurements to analytically estimate both bias and the uncertainty. In this study, approach to obtain the true value is to extract a "true" profile by filtering noise from the measured data. In previous paper, the digital filter with wavelet transformation (WT) is proposed and efficiency to remove the noise, however, the method is introduced the pseudo-Gibbs effect. Then, we propose the digital filter with new algorithm of total variation (TV). In this paper, the new algorithm of TV is proposed and the digital filter by new TV indicate that data is filtered without the pseudo-Gibbs effect. The digital filters by WT and new TV are applied on the sample data of actual measurement system to investigate their performance of noise reduction., TRANS TECH PUBLICATIONS LTD

  • Development of Novel Polishing System by Use of Acoustic trap
    Tomohiro Inada; Hirotaka Ojima; Libo Zhou; Teppei Onuki; Jun Shimizu, Based on the acoustic levitation phenomenon, we have proposed and developed an acoustic levitation/trap system to control the movements of free abrasives for the finishing of inner surfaces. Described in this paper are the theoretical analysis of levitation force generated in a standing wave field, and experimental results of levitation and trap. A simulation is first performed to determine the wave amplitude and frequency required to levitate the actual abrasives. Based on those results, we developed a system which consists of a sound transducer (speaker), a reflector (an aluminium plate), an amplifier and a function generator, and successfully not only levitated but also trapped actual abrasives in a cylindrical tube. It is found that the relation between the size, density of the abrasives and the power of the acoustic field (wave amplitude and frequency) fairly agreed with the theoretical prediction. Also, the kinetics of levitated abrasives including their positions and movements are precisely controllable by varying the wave frequency and switching from one node position to another., TRANS TECH PUBLICATIONS LTD

  • Design of Digital Filters for Si Wafer Surface Profile Measurement - Denoising by Total Variation
    Hirotaka Ojima; Kazutaka Nonomura; Libo Zhou; Jun Shimizu; Teppei Onuki, In the semiconductor industry, high resolution and high accuracy measurement is needed for the geometric evaluation of Si wafers. The flatness parameters are important to evaluate the wafer profile and are required to be the same level as the design rule of IC, and the tolerance for flatness is very tight. According to SEMI (Semiconductor Equipment and Materials International) standards, the required wafer flatness will be 22 nanometres by the year 2016. However, to obtain a higher resolution for sensors, the uncertainty becomes very large compared to the resolution and influences the measured data when the noise is increased. High resolution instruments always incorporate a certain degree of noise. In the presence of noise, form parameters are normally biased. Correction and compensation need a large population of measurements to analytically estimate both bias and uncertainty. The estimation is still far from perfect because of the nature of noise. Another approach is to extract a "true" profile by filtering noise from the measured data. For the purpose of noise reduction, low-pass filters by Gaussian smoothing and Fourier transform are often used. The noise is normally considered to be a component of small deviation (amplitude) with high frequency which also takes a normal distribution around zero. However these conventional filters can remove the noise in the spatial frequency domain only. So, it is essential to design a filter capable of removing the noise both in the spatial frequency domain and the amplitude component. Thus, we have designed and developed new type of digital filter for denoising. We introduce two new digital filters. One is wavelet transform capable of denoising in the spatial frequency domain and amplitude component, and the other is total variation that can be applied to discontinuous signals without introducing artificial Gibbs Effects., TRANS TECH PUBLICATIONS LTD

In this work, diamond grinding for thinning silicon wafers was carried out on an ultra-precision grinding machine. The thinning performance and the minimum wafer thickness were investigated under different grinding conditions. It was found that the grain depth of cut that was used to characterize the overall grinding conditions played an important role in the determination of the final grinding performance. The relationship between the subsurface damage of the ground wafer and the minimum wafer thickness achieved was also revealed., SAGE PUBLICATIONS LTD

  • Influence of Surface Micro Texture on Photocatalitic Function of Titanium Dioxide Film
    Jun Shimizu; Go Kobayashi; Naomi Hasegawa; Takeyuki Yamamoto; Hirotaka Ojima; Teppei Onuki; Libo Zhou, This study aims to develop a high-functional photocatalytic film, of which surface is regularly textured by the micro machining technique in order to earn the real surface area. In this work, a regularly textured TiO2 film surface was fabricated by anodic oxidizing a pure titanium plate with regularly arrayed micro cutting grooves, and its wettabilty was evaluated. Micro cutting grooves were machined by a 3-axis NC control precision machine tool with a single point diamond cutter. Anodic oxidation experiments were conducted by using the self-developed equipment with diluted acetic acid as the electrolyte. As a result, it was found that the wettability of the TiO2 film surface regularly textured by synchronized 3-axial micro cutting was superior to those of the mirror finished or irregularly textured surfaces under the irradiation environment by the ultraviolet rays., TRANS TECH PUBLICATIONS LTD

  • Image Based Defect Detection Algorithm by Use of Wavelet Transformation
    Kaoru Takamori; Hirotaka Ojima; Libo Zhou; Teppei Onuki; Jun Shimizu; Takeyuki Yamamoto, Today, there is an increased need for quality control in the manufacturing sectors. Particularly, the automated detection of the product surface defect is essential to fulfill the requirement of quality assurance. Generally, use of image processing to detect defects on the product surfaces is based on the pattern matching technique which necessitates preparation of possible geometric patterns of defects prior to such trials. Therefore, this method is unable to deal with exceptional defects of prepared patterns. In this study, we have proposed an algorithm of surface defect detection by the application of wavelet transformation to the image processing. This paper provides the algorithm and results of experiment that show the effects of process parameters on the detection accuracy., 一般社団法人日本機械学会

  • Nanogrinding of multi-layered thin film amorphous Si solar panels
    Taro Sumitomo; Han Huang; Libo Zhou; Jun Shimizu, Nanogrinding was performed on the cross-sections of amorphous Si thin film solar panels, which are nanoscale multi-layer structures consisting of hard and brittle materials. The deformed structures of the panel cross-sectional surfaces after grinding were investigated using electron and atomic force microscopy. The nanogrinding results were compared with those obtained from polishing and nanoscratching, demonstrating that the three processes had produced consistent surface characteristics. Though nanogrinding produced nanometric surface roughness with ductile material removal, but could cause cracking, edge chipping and delamination at thin film interfaces. The results of this work are of value for developing the efficient machining process for thin film solar panels and other brittle multi-layer materials. (C) 2011 Elsevier Ltd.

  • Finite element analysis of deflection and residual stress on machined ultra-thin silicon wafers
    Y. B. Tian; L. Zhou; Z. W. Zhong; H. Sato; J. Shimizu, The demand for ultra-thin silicon wafers has escalated in recent years with the rapid development of miniaturized electronic devices. Residual stress generated in the thinning process has a great influence on the machining quality of ultra-thin wafers. This work has developed a 2D axisymmetric finite element (FE) model to predict the deflection and full-field residual stress of ground ultra-thin wafers. The FE model consists of two-layer structures, i.e. a damage layer induced by the thinning process and a bulk silicon crystal layer without defects. A series of uniform in-plane strains is applied to the damage layer to simulate machining-generated initial stress. A full-field residual stress distribution in a machined ultra-thin wafer is predicted with the developed FE model after the initial stress is released. Based on the FE model, effects of wafer geometrical dimensions and loaded initial strain (or stress) on the maximum compressive/tensile residual stress and the maximum wafer deflection are revealed. The model is finally verified by comparing the simulated wafer deflection with the measured value. Based on this work, the deflection and residual stress of a machined ultra-thin wafer can be conveniently predicted., IOP PUBLISHING LTD

  • Development of CMG Wheels for Stress Relief in Si Wafer Thinning Process
    Yuki Mikami; Libo Zhou; Jun Shimizu; Hirotaka Ojima; Yoshiaki Tashiro; Sumio Kamiya, In recent semiconductor industry, production of ever flatter, thinner and larger Si wafer are required to fulfill the demands in high integration and cost reduction. A severe problem encountered in wafer thinning process is the warp and distortion of wafer induced by the residual stress and subsurface damage. Chemo-mechanical grinding (CMG) process is emerging process which combines the advantages of fixed abrasive machining and chemical mechanical polishing (CMP), offers a potential alternative for stress relief. This paper studies the influence of the wheel manufacturing process on the wheel physical properties. Three-factor two-level full factorial designs of experiment are employed to reveal the main effects and interacted effects of mixing method and filtration of raw materials on the bending strength and elastic modulus of CMG wheel. The difference in wheel properties is discussed by association with CMG performance including wheel wear, grinding force and surface roughness., TRANS TECH PUBLICATIONS LTD

  • Molecular Dynamics Simulation of Chemical Reaction Assisted Grinding of Silicon Wafer by Controlling Interatomic Potential Parameters
    Jun Shimizu; Libo Zhou; Takeyuki Yamamoto, This paper reports a few molecular dynamics simulations of chemo-mechanical grinding (CMG) and chemical mechanical polishing (CMP) of silicon wafer by controlling the interatomic potential parameters to imitate the chemo-mechanical or mechano-chemical reactions between an abrasive grain and a Si wafer. Some comparisons among diamond grinding, CMG and CMP were made by using the proposed simulation models. From the simulation results, reductions of surface damages, wears of abrasive grain and scratching forces in CMG were confirmed to be same as observed in actual CMG experiments by a CeO(2) abrasive wheel, and the availability of proposed simulation model was verified to some extent, even though further improvements in both of the models, especially in the CMP model, are necessary., AMER SCIENTIFIC PUBLISHERS

  • Effect of Wheel Additive On Chemo-Mechanical Grinding (CMG) of Single Crystal Si Wafer
    H. Takahashi; Y. B. Tian; Y. Mikami; J. Shimizu; L. Zhou; Y. Tashiro; H. Iwase; S. Kamiya, Chemo-mechanical grinding (CMG) process is a promising process for large-sized Si substrate fabrication at low cost. However, effect of additive in CMG wheel is not completely understood yet. In this paper, three different CMG wheels were developed, in which one excluded additive and the other two contained two kinds of additive i.e. silicon dioxide and sodium carbonate. Grinding experiments were conducted to explore the influence of exclusion of additive and inclusion of different kinds of additive on CMG performance. The grinding characteristics of the three wheels were also analyzed and discussed to reveal the roles of wheel compositions in CMG process. This work provides some fundamental insights for the selection of different types of additive for optimization of CMG wheel., TRANS TECH PUBLICATIONS LTD

  • Design of digital filters for Si wafer surface profile measurement - Noise reduction by lifting scheme wavelet transform
    Kazutaka Nonomura; Masashi Ono; Libo Zhou; Jun Shimizu; Hirotaka Ojima, Recently in semiconductor industry, production of ever flatter, thinner and larger silicon wafers are required to fulfill the demands of high-density packaging and cost reduction. In geometric evaluation of Si wafers, according to SEMI (Semiconductor Equipment and Materials International) standards, the required wafer flatness approaches to the 22 nanometers by year 2016 [1]. For such application, uncertainty of measured data is encountered as a severe problem because the requirement has met the limit of available instrument in terms of resolution and reliability. In order to precisely evaluate the wafer profile, it is essential to remove the noise from the measured data. Described in this paper is design and development of digital filters for denoising. In previous paper, digital filters for denoising with Haar wavelet transform are described. In this paper, the new filters by use of 2(nd) generation wavelet transform (lifting scheme) are proposed and show better performance of decomposition in the spatial frequency domain and amplitude domain., TRANS TECH PUBLICATIONS LTD

  • Molecular Dynamics Simulation of Rubbing Phenomena in Ultra-Precision Abrasive Machining
    Jun Shimizu; Libo Zhou; Takeyuki Yamamoto; Han Huang, This study aims to clarify the friction and wear phenomena, which are of great importance in abrasive machining with atomic-scale material removal, such as polishing of magnetic disk substrates and CMP of semiconductor substrates. Various phenomena that occurred when a well-defined copper surface rubbed by an extremely fine rigid diamond abrasive, such asthe sliding without removal and the atomic-scale wear, were analyzed using a molecular dynamics model, in which the abrasive grain was connected to a three-dimensional spring and the holding rigidity of the abrasive grain was taken into account. A series of simulations using different indentation depths clarified that the one- or two-dimensional atomic-scale stick-slip phenomenon in proportion to the period of atomic arrays of workpiece surface occurred in the sliding processes without atomic removal. The results also demonstrated that the period and amplitude of the fundamental stick-slip wave varied when accompanied with atomic removal due to the increase in normal load., TRANS TECH PUBLICATIONS LTD

  • Enhancement of Photocatalytic Reaction of Titanium Dioxide Film by Surface Texturing
    Jun Shimizu; Libo Zhou; Kaoru Takamori; Hirotaka Ojima; Takeyuki Yamamoto; Han Huang, This study aims to study the influence of surface topography on the photocatalytic reaction of TiO2 film surfaces. In this work, a textured TiO2 film surface was fabricated by anodic oxidizing a titanium plate with micro grooves, and its wettabilty was evaluated. Micro grooves were machined on a 3-axis NC control precision machine tool using a single point diamond cutter with a tip radius of several hundred nanometers. Anodic oxidation experiments were conducted by using the self-developed equipment with diluted acetic acid as the electrolyte. It was found that the wettability of the TiO2 film surface textured by microcutting was superior to that textured by polishing under the irradiation environment of ultraviolet rays. The wettability of photocatalytic film surfaces could be improved by increasing the surface area., TRANS TECH PUBLICATIONS LTD

  • Mold Fabricated by Nanoscratching for Nanoimprint Lithography
    Wataru Ohsone; Jun Shimizu; Libo Zhou; Hirotaka Ojima; Teppei Onuki; Takeyuki Yamamoto; Han Huang, The MEMS technology for various nano/micro devices often requires special facilities and complicated and multistage processes, thus the fabrication cost is extremely high. This research aimed to fabricate nanoscale basic structures on silicon substrates using nanoscratching, which can be potentially used to make nano/micro molds for nanoimprint lithography. In this study, various nano/micro-scale structures, such as groove and, single and multiple layer structures were generated on the silicon substrate using an atomic force microscope equipped with a sharp probe made of monocrystalline diamond. The nanoimprint experiment was also performed using the fabricated single-step mold and silicon-resin to fabricate single island structures., TRANS TECH PUBLICATIONS LTD

  • Improvement in oxide-pattern sizes controllability on scanning probe nanolithography
    Teppei Onuki; Takashi Tokizaki; Ojima Hirotaka; Jun Shimizu; Libo Zhou, Pattern size controllability of SPM-based nano-lithography especially in vertical direction was improved using in-situ height and depth measurements at the processed point. The transient oxide growth was monitored by light transmission (depth of the oxide, in sample metal surface) and topographical signals measurements obtained from a scanning near-field optical microscope. First, we investigated oxidizing rate limitation on titanium film. At the voltage rise faster than 10 V/sec, the depth growth didn't follow the voltage change in spite of immediate upheaval growth. This result suggested the rate determining of reactive chemicals transport in the titanium oxide. Next, we discovered improvement in the process stability on intractable materials (e.g. iron group elements or noble metals; manganese in this paper) by using thin cap layer of titanium. As the result, the oxidization reaction progressed moderately due to the facts that the oxide of the cap layer is electrical insulative and restriction of the permeability of the reactive chemicals (ingredients of the oxide) that were electrochemically generated at apex of the probe tip., TRANS TECH PUBLICATIONS LTD

  • Research on chemo-mechanical grinding of large size quartz glass substrate
    Libo Zhou; Takeshi Shiina; Zhongjun Qiu; Jun Shimizu; Takeyuki Yamamoto; Toshiaki Tashiro, Finishing process of quartz glass substrate is meeting great challenges to fulfill the requirements of photomask for photolithography applications. For the final finishing of the substrate surface, chemical mechanical polishing (CMP) is often utilized. Those free abrasive processes are able to offer a great surface roughness, but sacrifice profile accuracy. On the other hand, the fixed abrasive process or grinding is known as a promising solution to improve accuracy of profile geometry, but always introduces damaged layer. Chemo-mechanical grinding (CMG) is potentially emerging defect-free machining process which combines the advantages of fixed abrasive machining and CMP. In order to simultaneously achieve high surface quality and high profile accuracy, CMG process has been applied into machining of large size quartz glass substrates for photomask use. Reported in this paper are CMG performances in finishing of quartz glass substrates including material removal rate (MRR), surface roughness, flatness and optical characteristics.

  • ステレオ視法によるSEM 画像の3 次元形状計測および復元
    尾嶌裕隆; 村上幸博; 大塚春樹 笹本侑弥; 周 立波; 清水 淳; 江田 弘, The image processing technology has now been widely applied into many areas such as electronics, manufacturing and security. However, most of those applications are based on two dimensional images. Recently, there are increasing demands of 3D information for new applications. The incoming visual information via a digital imaging device (ex. CCD) is digitized into pixels in plane with color/gray scale. Each pixel contains 2D positional information, the CCD thus offers an 2D orthogonal coordinate, but loses the 3rd dimension in depth for objects in view. The aim of this research is to develop an algorithm for acquisition and configuration of 3D information by means of binocular stereo vision. In this paper, the 3D data acquisition and reconstruction are demonstrated at static SEM stereopairs. Also the accuracy of acquired data is discussed., 公益社団法人 精密工学会

  • Study on a microlathe with visual feedback control
    Hirotaka Ojima; Libo Zhou; Jun Shimizu; Hiroshi Eda, Micromeso Mechanical Manufacturing (M4) technology has recently attracted attentions as an alternative micromachining solution because of its potentials of processing a wide range of materials into three-dimensional forms. In this research, using a microlathe, which is installable and operational in a Scanning Electron Microscope (SEM), we control the positions and movements of the cutting tool directly with visual feedback scheme from CCD camera. Unlike the conventional feedback control which positions the X-Y table only, this scheme offers a direct control of the position, path and speed to the tool tip. We compare the tool paths with/without visual feedback control, and found the error of the path with visual feedback control is within ±5 pixels (30 μ m). Cutting test is performed to confirm the effect of the visual feedback control scheme and an average of difference between the resultant shape and the ideal profile is less than 10 m. © 2009, Inderscience Publishers.

  • Study on Improvement of Material Removal Rate in Chemo-mechanical Grinding (CMG) of Si Wafer
    J. Sasaki; T. Tsuruga; B. Soltani; T. Mitsuta; Y. B. Tian; J. Shimizu; L. Zhou; H. Eda; Y. Tashiro; H. Iwase; S. Kamiya, Silicon wafer thinning process is meeting great challenges to fulfill requirements of ultra-thin IGBT for automotive applications. Chemo-mechanical grinding (CMG) process is potentially emerging stress relief thinning process which combines the advantages of fixed abrasive machining and chemical mechanical polishing (CMP). A major issue in CMG of Si wafers is the relatively low material removal rate (MRR). This paper studies the influence of the wheel specifications and grinding conditions on the MRR of CMG. Two sets of three-factor two-level full factorial designs of experiment (DOE)[1] are employed to reveal the main effects and interacted effects of CMG wheel specifications and grinding parameters on MRR. The optimal combination scenarios for improving MRR of CMG are analysized and obtained. By use of the optimal CMG wheel and grinding parameters, the MRR of more than 60nm/min is achieved., TRANS TECH PUBLICATIONS LTD

    Keisuke Azusawa; Yuta Ishii; Jun Shimizu; Libo Zhou; Hiroshi Eda, TiO2 has some unique photocatalytic functions and some of them have been utilized industrially, and further functional enhancement and performance enhancement of TiO2 have been required. Under such circumstances, this study aims to clarify the influence of surface topography on the photocatalytic reaction of TiO2 film surface. As the first step, the optimum mixing ratio in film preparation by using TiO2 powder was examined and the films with several kinds of surface roughnesses were prepared. And, the influence of surface topography on the wettabilty, which is one of the photocatalytic functions of TiO2 was evaluated. As a result, it was confirmed that the wettability of TiO2 films could be improved by increasing both the surface roughness and actual surface area under the ultraviolet rays irradiation environment., TRANS TECH PUBLICATIONS LTD

  • Fundamental Research on Generation of Nanostructure by Means of Local Anodic Oxidation
    Yurnetaka Suehisa; Toshiaki Aoki; Jun Shimizu; Libo Zhou; Hiroshi Eda, A method to easily and economically manufacture more precise patterns compared with usual MEMS technique has been searched for. Under such circumstances, this research aims to clarify the formation of nano-scale protrusion structure produced by local anodic oxidation on Si wafer surface in expectation of the nano/micro mold production for nanoimprint lithography in future. In this report, the influences of contact width and distance between probe tip and Si wafer surface (distance between terminals) on the size and shape of protrusion patterns were examined in order to clarify the fundamental phenomena in local anodic oxidation. A scanning probe microscope equipped with a current measuring unit was utilized in local anodic oxidation experiments. As a result, it was confirmed that the size of generated protrusion structure became larger with increasing the contact width and became smaller with increasing the distance between probe tip and Si wafer surface. These facts will be useful in producing 3-D nanostructures in future., TRANS TECH PUBLICATIONS LTD

  • Elimination of surface scratch/texture on the surface of single crystal Si substrate in chemo-mechanical grinding (CMG) process
    Y. B. Tian; L. Zhou; J. Shimizu; Y. Tashiro; R. K. Kang, Si wafers are widely used as a substrate material for fabricating ICs. The quality of ICs depends on the quality of Si wafers. The chemo-mechanical grinding (CMG) with soft abrasive grinding wheels (SAGW) has been recently found to be a great potential process for machining Si wafers to generate superior surface quality at low cost. However, there have been very few studies on observing variation of topography of scratch/texture and understanding basic eliminating process of scratch/texture on the ground Si wafer. Furthermore, few reports on the variation of surface roughness and material removal rate (MRR) during CMG process and relationship between MRR and surface roughness during CMG process are presented. In this paper, a series of CMG experiments have been conducted to study the elimination process of artificial scratches created on etched Si surfaces and residual textures induced by SD1500 diamond wheel in CMG process, and to understand the topography variations of Si surfaces and some basic grinding characteristics during CMG process.

Chemo-mechanical grinding (CMG) process is a promising process for large-sized Si substrate fabrication at low cost. An encountered issue in current CMG process of Silicon (Si) wafers is metallic contaminations on ground Si wafer surface, which is attributed to the existence of sodium carbonate in wheel compounds.

  • Modeling and analysis of effects of machine tool stiffness and cutting path density on infeed surface grinding of silicon wafer
    Libo Zhou; Takahito Mitsuta; Jun Shimizu; Takuji Tajima, Many models [1-3] have been proposed to study the infeed grinding of Si wafers and to understand its effects on the surface generation. However, most exiting models are based on 2D/3D kinematical analysis of the wheel or its cutting edges, thus unable to suggest the behavior at the interface of wheel/substrate including effects of the elastic deformation and the cutting path density. In this paper, a new grinding model of capable to incorporate the machine tool stiffness and the substrate contact rigidity has been developed. By taking the effect of cutting path density into account, this model is able to give a better explanation of interference between the cutting edge and substrate, and the geometrical profile generated in an infeed grinding scheme., TRANS TECH PUBLICATIONS LTD

  • Molecular Dynamics Simulation of Adhesion Effect on Material Removal and Tool Wear in Diamond Grinding of Silicon Wafer
    Jun Shimizu; Hiroshi Eda; Libo Zhou; Hidemitsu Okabe, 筆頭著者, This study aims to clarify the interaction between a silicon wafer and individual diamond abrasives in grinding to support the estimation of optimal grinding conditions for minimizing the subsurface damages and maximizing the removal rate. In this paper, the effects of adhesion (or lubrication) between a Si wafer and a diamond abrasive on the material removal and tool wear were analyzed by means of the molecular dynamics simulation. A few simulations were performed with changing the dissociation (cohesion) energy of a Morse potential function between a pair of Si and C atoms to evaluate the influence of adhesion on the material removal process. As a result, a trend similar to the actual diamond grinding process of silicon wafer was confirmed, which suggested that the reduction in adhesion (or proper lubrication) is effective for the reduction in subsurface damages, grinding forces, grinding temperature and tool wear, but may lead to reduction in the material removal rate as well., Japanese Society of Tribologists

  • Molecular dynamics simulation of effect of grinding wheel stiffness on nanogrinding process
    Jun Shimizu; Libo Zhou; Hiroshi Eda, This paper intends to address an approach of Molecular Dynamics (MD) simulation to clarify the material deformation and removal mechanism between an abrasive grain and workpiece. The workpiece and the abrasive grain are assumed to consist of mono-crystalline copper and rigid diamond, respectively. In the present simulation model, influence of the stiffness of grinding wheel or polishing pad is taken into consideration. From the simulation results, relationships between material removal process and dynamics of the slip deformation, influence of the grinding wheel stiffness on the chip formation process and the actual depth of cut and so on, are clarified. These results indicate that the MD simulation has an advantage in deciding the stiffness of the tools and in estimating the actual depth of cut. © 2008, Inderscience Publishers.

The droplet and the substrate were assumed to consist of pure aluminum, and the Morse potential was postulated between a pair of aluminum atoms. In this report, the influence of the impact parameters such as the droplet velocity and the droplet diameter on flattening behavior were analyzed. As a result, the following representative conclusions were obtained: (a) the flattening ratio increases in proportion to the droplet velocity and the droplet diameter; (b) the flattening ratio for nanosized droplet can be reorganized by the same dimensionless parameters of the proper physical properties, such as the viscosity and the surface tension, as those used in the macroscopic flattening process., SPRINGER

  • Visual feedback control of a micro lathe
    Hirotaka Ojima; Katsuhiro Saito; Libo Zhou; Jun Shimizu; Hiroshi Eda, Micromachining progresses rapidly in recent years. In this research, a micro lathe which is installable and operational inside SEM vacuum chamber has been designed and developed. As a first step, visually guided micro lathe system is developed with image of CCD camera device instead of SEM image. Unlike the conventional feedback control which positions the X-Y table only, this scheme offers a direct control of the position, path and speed of the tool tip. Using proposed method, cutting experiment was achieved, and it is confirmed that developed micro lathe system is effective to do cutting., SPRINGER-VERLAG LONDON LTD

  • Study on subsurface damage generated in ground Si wafer
    Bahman Soltani Hossemi; Libo Zhou; Tatsuya Tsuruga; Jun Shimizu; Hiroshi Eda; Sumio Kamiya; Hisao Iwase, In this paper, we study and evaluate the subsurface damage of the ground wafers to understand the effect of residual stress on the wafer deflection. The experimental results show that two indexes of depth of the damaged layer and degree of the residual stress are directly associated with the warpage of wafer. The degree of the damage decreases with an increasing in grit size of diamond wheel. The theoretical analysis suggests that the minimally achievable thickness of wafer is proportional to the degree of the damage introduced by respective process., SPRINGER-VERLAG LONDON LTD

  • Experimental and simulation research on influence of temperature on nano-scratching process of silicon wafer
    H. Okabe; T. Tsumura; J. Shimizu; L. Zhou; H. Eda, This study aims to clarify the interaction between Si wafer and individual diamond abrasives in grinding at nanometer level and to estimate the grinding conditions for minimizing the surface defect. This paper reports on the results obtained through nano-scratching experiments in vacuum by an atomic force microscope (AFM) and simulations by using the molecular dynamics method by applying Tersoff potential for Si-Si atomic interaction under room and high temperature, respectively, to examine the influence of the grinding heat on the materials removal process. As a result, it was proven that the scratch groove under high temperature becomes deeper than that under room temperature from the experiments, and it was also observed that the formation of the amorphous phase around the scratch groove under high temperature becomes a little bit larger than that under room temperature from the simulations.

  • Study on structure transformation of Si wafer in grinding process
    Libo Zhou; Makoto Yamaguchi; Jun Shimizu; Hiroshi Eda, In this paper, the surface and subsurface of silicon wafers ground by different wheels have been studied. In the conventional grinding with diamond wheels, it is shown from the top that the subsurface of wafer consists of amorphous Si, followed by a thin damaged layer, strained crystal with a large compressive residue stress, and then the bulk material in single crystal. In a severe condition which causes grinding burn, part of amorphous Si is re-crystallized to form a poly-crystal Si, and part of amorphous Si possibly reacts with oxygen to form SiO22. This phenomenon becomes more pronounced in the backgrinding process with a fine grit diamond wheel when the conditions are improperly selected. In order to obtain a defect-free crystal Si structure in grinding, authors have proposed a new chemo-mechanical grinding (CMG) process which enables to remove Si from wafer but with no structure transformation induced to its surface.

  • Fabrication and evaluation for extremely thin Si wafer
    Libo Zhou; Bahman Soltani Hosseini; Tatsuya Tsuruga; Jun Shimizu; Hiroshi Eda; Sumio Kamiya; Hisao Iwase; Yoshiaki Tashiro, Grinding process on the Si wafer develops subsurface damage, which remarkably degrades deflective strength of the wafer and constitutes a barrier against producing a thin wafer for low-profile packaging. In this paper, the authors propose a new index for evaluation of the Degree of Subsurface Damage (DSD). Requiring no costly instrument, the new index is easily calculated via the external geometry of the ground wafer. With the new index, it is able to quantitatively evaluate the subsurface damage introduced by different processes (or wheel) and to estimate the minimally achievable thickness of the wafer by each process. Also, a novel fixed abrasive process of Chemo-Mechanical Grinding (CMG) has been proposed for stress relief. All results indicate that the subsurface damage after CMG is nearly zero. © 2007 Inderscience Enterprises Ltd.

  • Molecular dynamics analysis of elementary process of coating by a high-temperature, high-speed droplet - (Flattening process and atomic behavior of a droplet)
    Jun Shimizu; Etsuji Ohmura; Yoshifumi Kayashi; Shoichi Kiyoshima; Hiroshi Eda, Three-dimensional molecular dynamics simulation was conducted to clarify at an atomic level the flattening process of a high-temperature droplet impacting a substrate at high speed. The droplet and the substrate were assumed to consist of pure aluminum, and the Morse potential was postulated between a pair of aluminum atoms. By Visualizing the analytical results, the processes of melting and solidification, temperature distribution, deformation velocity, and potential energy of atoms of the droplet were clarified. The following conclusions were obtained: (1) Transfer of the droplet atoms to the horizontal direction in the flattening process increases in proportion to the horizontal distance from the central axis of the droplet. (2) The increase of the flattening ratio of the droplet ends as soon as solidification of the droplet starts from the outside edge of the droplet. This behavior indicates the end of flattening., JAPAN SOC MECHANICAL ENGINEERS

  • Defect-free fabrication for single crystal silicon substrate by chemo-mechanical grinding
    L. Zhou; H. Eda; J. Shimizu; S. Kamiya; H. Iwase; S. Kimura, IC chips are built on Si substrates which must have a high degree of crystalline perfection. The single crystal Si ingot is first sawn into wafers, each of which then undergoes lapping, etching and several steps of polishing to remove the mechanical imperfection and to achieve mirror surfaces. An alternative process has been newly developed by effective use of solid-state reaction between the CeO2 abrasives and Si. Si is removed in a form of amorphous Ce-O-Si at a dry condition. The fabricated phi 300 mm Si wafers are examined on both surface and subsurface. The results show that 1) the surface is generated by fixed abrasives following grinding dynamics, 2) no defect or mechanical (structural) imperfection is introduced during fabrication and 3) far better quality is achieved than that by CMP., TECHNISCHE RUNDSCHAU EDITION COLIBRI LTD

  • A novel fixed abrasive process: Chemo-mechanical grinding technology
    Libo Zhou; Jun Shimizu; Hiroshi Eda, As finishing techniques for Si wafers, the free abrasive processes like lapping and polishing are able to offer a better surface roughness when finer abrasives are applied, but fall short of maintaining profile accuracy when the wafer size increases. On the other hand, the fixed abrasive process or grinding is known as a promising solution to improve accuracy of profile geometry, but always introduces subsurface damages. In order to simultaneously achieve both surface quality and geometry accuracy, this research has proposed a novel chemo-mechanical-grinding (CMG) process by effective use of chemical reaction in the grinding process. CMG wheels which contain chemically active abrasives and additives have been developed, characterised and applied into grinding of φ300 mm bare Si wafers. The ground wafers are examined on both surface and subsurface. The results show no subsurface damage produced due to machining. A defect-free surface so far only achievable by polishing has been realised by the fixed abrasive process. A discussion is also made to understand the mechanism and chemical reaction involved in the process. Copyright © 2005 Inderscience Enterprises Ltd.

  • Axisymmetric aspherical form generation for large diameter optical components
    L Zhou; J Shimizu; H Eda, Proposed in this paper is a new method for axisymmetric form generation. The equipment required is a face grinding machine with two spindles configured as one for grinding wheel, and to face another for workpiece. The infeed grinding is applied at the position of the wheel half overlapped against the workpiece. When the axes of two spindles are set to be parallel, the interference between the wheel and workpiece are made in a plane perpendicular to the axes so that the profile formed is flat. Other than the above condition, the forms are in axisymmetric three-dimension. By taking account of the extra effects of cutting path density, it is further able to give a variation in concave or convex profiles of corn, spherical or ellipse shapes. This new method receives no effect of tool wear, therefore, is effective in form generation for large diameter optical components. The newly proposed method has been applied to phi 200mm optical glass in this research to produce a flat-convex lens., TRANS TECH PUBLICATIONS LTD

    LB Zhou; J Shimizu; K Shinohara; H Eda, Sponsored by New Energy and Industrial Technology Development Organization (NEDO) and the Ministry of Education, Science and Culture (MESC) of Japan, this project has developed an advanced machining system for diameter 300 turn silicon wafer, using fixed abrasive instead of conventional free slurry, to provide a totally integrated solution for achieving the surface roughness R-a < I nm (R-y < 5-6 nm) and the global flatness < 0.2 mum/diameter 300 mm. Use of state-of-the-art technologies for ultra precision machine tools has made it possible to precisely control the motion and repeatability of each cutting edge. The behavior of each grain and its effect on surface generation become analytical in 2D manner [J JSPE 68(1) (2002) 125]. Taking one step further, this paper has developed a 3D model for infeed grinding which is often used in silicon grinding systems, and mathematically described the cutting path and effects on the surface roughness and flatness.

  • Material removal mechanism beyond plastic wave propagation rate
    LB Zhou; J Shimizu; A Muroya; H Eda, Discussed in this report are the material removal mechanisms below and beyond its static plastic wave propagation rate. The ductile materials are expected to behave elastically throughout most of its strength range, and apparently become "brittle" as cutting speed exceeds its static propagation rate. This behavior leads to a significant reduction in plastic flow/deformation and work hardening during the machining process, so as possibly to improve the total surface integrity. In order to achieve such high speed machining, a super high speed grinding machine has been newly developed by using the latest technologies, which is able to attain 600 m/s peripheral speed and 10 nm/step positioning accuracy. This study particularly investigates the cutting speed effect on the typical ductile metals of pure aluminum (A 1199) and aluminum alloy (A5056), and reveals that static propagation rate is a breaking point from where the removal mechanism is different.

  • Molecular dynamics analysis of sliding friction and wear mechanisms: Behaviors of zero-wear transition regions               
    Jun Shimizu; Hiroshi Eda; Libo Zhou, Various molecular dynamics simulations have been performed in order to clarify friction and wear mechanism in their transition region at an atomic level. The specimen and the slider are assumed to consist of monocrystalline copper and rigid diamond, respectively, and the Morse potential is postulated between a pair of atoms. The atomic behaviors in a plane corresponding to the (111) plane of the copper are simulated dealing with a plane strain problem. In the simulations, the influence of the indentation depth on friction-and-wear phenomena was investigated. As a result, the friction-and-wear process of copper by the hard particle were classified into four regions as follows: (1) friction process by atomic-scale stick-slip phenomenon, (2) friction process with elastic deformation, (3) wear process with ploughing due to removal of atoms, and (4) wear process with ploughing due to plastic deformation. Each feature was clarified. © 2004 by Allerton Press, Inc.

  • Development of biological-micro-manipulation system in scanning electron microscope
    H Eda; T Ishikawa; Y Tomita; Y Yamamoto; L Zhou; K Kawakami; J Shimizu, In the applications of biological and medical engineering, there are increasing demands of implementing dissection, inspection and/or evaluation at the sub-micron scale. Currently, most of such operations are manually done by highly skilled operators with the assistance of scanning electron microscopes or CCD camera. The limited visible area at a high magnification of SEM makes it more difficult for the operator to trace the target. The operators have also to experience a long time training to familiarize the feeling of micro-scale movements in order to achieve high repeatability and high accuracy. The operations are tedious and time-consuming. It is, therefore, strongly expected to develop a manipulation system possible for unskilled operators to easily execute the desired tasks.
    The our goal is to develop a manipulation system enabling unskilled operators to deal with biological objects in sub-micro size as easily as to deal with objects in usual size. The scope of this paper includes the conceptual design, the prototype development, field tests and the operability evaluation.
    The system is modularized into the manipulation unit, the control unit and the man-machine interface. The manipulation unit is further comprised of a twin-arm manipulator mounted on a rotary table and a specimen stage with four degrees of freedom linear along X, Y and Z direction, and rotational around the Z-axis. The manipulator is driven by PZT actuators with magnifier elements and able to cover an envelope as wide as 200mum for each axis of X, Y and Z. Instead of doing a direct operation, the operator steers the manipulator via an user-friendly interface which is designed to absorb the optical and mechanical variations.
    The control unit merges the Visual information of the SEM(Low vacuum type) and the manipulation information from the user interface and derives the optimum locomotion from the arm for the desired operation. The image processing algorithm of the vision system can capture specified object and auto-locate it with in the scope of SEM(Low vacuum type). With this function, the operator is able to concentrate on the operation without paying much attention to the changes in SEM magnification and other conditions. By feeding the force exerted on the tool tip back to the joystick the operator actually feel the resistance so that the contact between the tool and the specimen, and force applied to the specimen are identical.
    The field tests has demonstrated that the modules are able to cooperate each other to complete the complicated tasks., IEEE

    江田 弘; 周 立波; 近藤 良; 中野博民; 森 輝夫; 清水 淳, In order to achieve damage free surface of Si wafer by a single step grinding process, each cutting edge should be controlled below the critical depth of cut. Additionally, the achievable wafer flatness by infeed grinding significantly depends upon the alignment between the wafer and the wheel. As one of the core technologies of an integrated manufacturing system for Φ300mm silicon wafer, a GMM (giant magnetostrictive material) actuated positioning/alignment device has been designed and developed to control half a ton payload at Åresolution over the several μm stroke range (about 5μm) and simultaneously to align the co-axis between the work and wheel at the resolution of 0.1".

  • Manipulation of the universal rotational mechanism for biological application
    T Ishikawa; H Eda; Y Yamamoto; K Kawakami; L Zhou; J Shimizu, Recently, in the potential application of biological and micro-nano technology, there are increasing demands in areas such as bio-cell manipulation and micro fabrication at the micron or nano scale. However, it is very difficult to carry out direct micro manipulations. In contrast to macroscopic working procedures which permit free manipulation of objects with the both hands, microscopic working procedures involve the observation and manipulation of the object within a very small area under a scanning electron microscope.
    We are currently developing a manipulation system of biological tissue and cell engineering. For such applications, we need to ascertain the presence of various fungi, bacilli, etc. on a object and approach any point of the object from any direction. To achieve the desired operation, we have developed a proto-type of a two-arm micromanipulator mounted on a rotary table around any given point on a object, allowing biological objects to be approached from any direction.
    The manipulation system is further comprised of a twin-arm manipulator mounted on a rotary table and a specimen stage. Each arm comes with three actuators superimposed one on the top of another in order to move along the XYZ axial direction. The manipulator is driven by PZT actuators with magnifier elements and able to cover an envelope as wide as 200 mum for each axis of X, Y and Z. The rotary table is supported by a pair of rollers set perpendicularly and driven by DC motor. The attitude of the roller pair is adjustable within three-degrees by the PZT actuators together with parallel plate magnifiers.
    In this paper, we investigate the need for a mechanism that permits controlled rotation around any given point during microscopic dissection, the principles of motion of our micromanipulation system, and the results of basic experiments with the system., IEEE

  • SiウエハのChemo-Mechanical-Grinding(CMG)に関する研究-第1報: CMG砥石の開発-
    周 立波,河合真二,本田将之,清水 淳,江田 弘,焼田和明, At ductile-mode grinding, the material is removed within a plastic region so that no crack remains on the corresponding surface after machining. By effectively using this mechanism, fixed abrasive process is seen as a promising solution to replace the lapping and polishing processes in manufacturing of large scale Si wafer. In principle, however, there is still plastic strains developed. This fact makes it very difficult to completely remove the damaged subsurface layer by fixed abrasives. To achieve a perfectly damage-free surface, this research has proposed a new chemo-mechanical-grinding (CMG) process by adding chemical effect into the grinding process. First described in this paper are the experimental results showing the feasibilities of the CMG process in reducing subsurface damage. Based on the preliminary test results, CMG wheels which contain chemically active abrasives and additives have been developed and characterized with a wide range of pH from acidity to alkalinity accordingly. The CMG has been mainly evaluated by the grinding performance on bear Si wafers, comparing to grinding with diamond wheels. From the technical and economical points of view, CMG is also highly expected to perform planarization function instead of chemical mechanical polishing (CMP) process. The primary tests of CMG have been done on shallow trench isolation (STI) patterned wafer to investigate the pattern dependency., 公益社団法人精密工学会

  • Simulation and experimental analysis of super high-speed grinding of ductile material
    J. Shimizu; L. B. Zhou; H. Eda, This study aims to reduce the work-affected layer of the machined surface by carrying out the grinding at the speed over static propagation speed of plastic wave of ductile materials and also aims to clarify such super high-speed machining mechanism. This paper reports on the result obtained through the molecular dynamics simulations and experiments on the super-speed grinding below and beyond static propagation speed of aluminum. From the simulation results, it is verified that the plastic deformation is reduced when the machining speed exceeds the material static propagation speed of plastic wave and its mechanism is completely different from that of the ordinary grinding process. Experimental results also show the improvement of the surface integrity when the machining speed exceeds the material static propagation speed of plastic wave. © 2002 Elsevier Science B.V.

  • 大口径シリコンウエハ研削加工における幾何と運動
    周 立波; 篠原一宏; 清水 淳; 江田 弘, To address the problems of throughput rate, post-process cleaning, environmental aspects as well as to achieve the total surface integrity for large-scale silicon wafers, the semiconductor industry is looking for a fixed abrasive solution as the alternative. As the result of intensive R&D, many achievements have been seen in machine tools, grinding wheels and process technologies, which make it possible to control the motion of each cutting edge very precisely. This paper kinematically analyzes the motion and path of cutting edge at plunge grinding with a cup-type grinding wheel, where the contact area is unchanged. Two facts have been revealed; 1) the cutting path pattern is determined only by the rotational speed ratio of the wafer against the wheel. 2) Once the grinding reaches the steady state, the cutting edge goes over the same path so that the cutting path pattern remains unchanged. Three problems have then been addressed from the cutting path pattern; 1) Different rotational speed ratio grants a different cutting path density, thus achieves significantly different surface roughness. 2) The cutting path density in the wafer center is higher than that at the fringe so that the surface roughness is inconsistent over the whole wafer. 3) The variation in the cutting path density also leads the ground wafer to a concave profile. Solutions are proposed on the basis of analytical and experimental results. 1) The criteria to terminate the grinding process are established to improve the surface roughness. 2) The wheel geometry is optimized to attain a consistent cutting path density. The results achieved in this research are also applicable to the generation of large-scale flat surface other than silicon wafer., 公益社団法人精密工学会

  • Molecular dynamics simulation of the contact process in AFM surface observations
    J. Shimizu; L. Zhou; H. Eda, In the present work, several molecular dynamics simulations have been performed to clarify dynamically the contact mechanism between the specimen surface and probe tip in surface observations by an atomic force microscope (SFM) or friction force microscope (FFM). In the simulation, a three-dimensional model is proposed where the specimen and the probe are assumed to consist of monocrystalline copper and rigid diamond or a carbon atom, respectively. The effect of the cantilever stiffness of the AFM/FFM is also taken into consideration. The surface observation process is simulated on a well-defined Cu{100} surface. From the simulation results it has been verified that the surface images and the two-dimensional atomic-scale stick-slip phenomenon, just as is the case for real AFM/FFM surface observations, can be detected from the spring force acting on the cantilever. From the evaluation of the behaviour of specimen surface atoms, the importance of the specimen stiffness in deciding the cantilever properties can also be understood. The influence of the probe tip shape on the force images is also evaluated. From the results it can be verified that the behaviour of the specimen surface atoms as well as the solid surface images in AFM/FFM surface observations can be understood using the molecular dynamics simulation of the model presented., Leaf Coppin Publishing Co.

  • 大口径φ300mmSiウエハ用超加工機械の開発
    江田 弘; 周 立波; 中野博民; 近藤 良; 清水 淳; 田島琢二, According to the roadmap of the semiconductor industry, the current φ200mm (8") silicon wafer will be replaced by φ300mm (12") by the year 2003. The present manufacturing process for silicon wafer includes lapping, etching and polishing. Such free slurry methods can achieve better surface roughness only when smaller abrasives are applied, therefore, require multi-stage equipments and are energy consuming. In addition to the low throughput, the current pressure-controlled process is also unable to fulfil the requirement on global flatness as the wafer size increases. To address the problems of throughput rate, post-process cleaning, environmental impact as well as to achieve the total surface integrity for φ300mm silicon wafer, the semiconductor industry was looking for a fixed abrasive solution as the alternative. This research has developed a one-stop manufacturing system for φ300mm silicon wafer, using fixed abrasive instead of conventional free slurry, to provide a totally integrated solution for achieving the surface roughness Ra < 1nm(Ry < 5-6nm) and the global flatness < 0.2μm/φ300mm. In addition to the space saving, this one-stop system also significantly reduces the total energy consumption, compared with the current process used for φ200mm Si wafer. Three core technologies : the hybrid process mechanics, the GMM actuated positioning/alignment device and the ecologically friendly coolant circulation system are described in this paper.

  • Simulation on high integrity surface generation of phi 300 Si Wafer with fixed-abrasive solution
    K Sagawa; H Eda; LB Zhou; J Shimizu, This study is done as one part of Regional Consortium Project of "Development of Transcendent Machine Tool and Core Technologies for phi300 Si Wafer", which aims to replace the conventional lapping, etching and polishing processes with fixed-abrasive solution. The newly developed grinding machine takes infeed-grinding form in order to keep the contact area unchanged and thereby to achieve the global flatness. The objective of this study is to simulate the achievable surface roughness by taking into account the contact stiffness between the abrasive and a point on the surface of workpiece, and to derive the principle of the grinding conditions and wheel specifications. Simulation results are as follows. The surface roughness at the center portion of the workpiece is better than that of at its fringe. Normal grinding force at the center portion of the workpiece is bigger than that of at its fringe. The processed wafer tends to be concave. The simulation results of surface roughness are found to agree with achieved experimental results., SPRINGER

  • Material Removal Ultrahigh Speed -Material Removal Mechanism Below and Beyond Plastic Propagation Speed-
    Libo Zhou; Jun Shimizu; Akihiro Muroya; Hiroshi Eda, Discussed in this report was the difference in material removal mechanism below and beyond its static plastic propagation speed. It was found that when the cutting speed exceeded the propagation velocity of material the workpiece became "brittle", resulted in the reeducation in plastic flow/deformation and work hardening, and thus the improvement in finished surface integrity. At such ultrahigh cutting speed, the ductile metal behaved much like the brittle materials. Based on these findings, the authors further proposed and developed a new concept of novel grinding machine of 600m/s speed and 10mm/step positioning capability, in order to achieve both high productivity and high accuracy at the same time. This study particularly investigated the cutting speed effect on ground surface of aluminum alloy (5056)., 一般社団法人日本機械学会

The simulation deals with the degradation process of copper mirror surface by the impact of a diamond debris, where the impact speed is 6 km/s and diameter of debris is 10.4 nm. Influence of mirror surface profile on the degradation mechanism and the surface roughness is evaluated as well. From several molecular dynamics simulations, various degradations formed on the ultra precision surface due to the impact of space debris can be inferred, such as generation process of craters, sizes of craters, stress distribution and temperature of the specimen. It is clarified that the impact of debris makes worse the quality of the mirror surface at least nanometer level even by an impact of space debris in the size of several nanometer., 公益社団法人精密工学会

    Motohiko Ii; Hiroshi Eda; Takaichi Imai; Masaya Nishimura; Takahiko Kawasaki; Jun Shimizu; Takeyuki Yamamoto; Libo Zhou, Using water-insoluble cutting fluids, which are good in lubricity but easy to mist, always risks firing and environmental problems. On the other hand, the current water-soluble coolants fail to deliver sufficient lubricity to heavy cutting applications. This study has newly proposed and developed a high water-content cutting fluid, based upon a new concept of having high lubricity despite of its water-soluble nature. As compared to the commercialized water-insoluble cutting fluid, the new cutting fluids shows a better capability of preventing oil mist and is fully applicable into cutting of various metallic materials, particularly effective in cutting of S45C and SUS304. The study also reveals a fact that a sulfur-type extreme pressure agent is the key element to enhance the cutting performance at high temperature., Elsevier Science Inc

    中野 博民; 内藤 雅将; 近藤 良; 江田 弘; 山本 佳男; 清水 淳, A conventional symmetrical three-phase system can be analyzed by using a conventional Bode Diagram. However it is difficult to analyze three-phase system using rotating coordinate transformations by means of the conventional Bode Diagram. Therefore this paper proposes an extended Bode Diagram in order to analyze a high-pass filter using rotating coordinate transformations and analyze the high-pass filter using rotating coordinate transformations., The Institute of Electrical Engineers of Japan

  • Application of giant magnetostrictive materials to positioning actuators
    Yoshio Yamamoto; Hiroshi Eda; Jun Shimizu, Recently giant magnetostrictive materials have drawn a lot of attentions because of their unique features. It is well known that the performance of a device using giant magnetostrictive material is affected by a preloading applied to the material. This paper presents a novel approach to monitoring and controlling the preloading in a compact giant magnetostrictive positioner. The proposed method not only provides a means to make a precise measurement of the preloading but also constitutes a sensing capability with which a displacement of the positioner itself can be measured. The positioner's structure as well as basic performances are described. The current paper also presents a new design of the positioner so that the effect of Joule heat can be kept minimal. Finite element analyses are conducted in parallel to the design modification in order to make sure that the giant magnetostrictive element can be driven in an efficient manner., IEEE

    H Eda; L Chouanine; J Shimizu; LB Zhou, This paper gives an overview of development of the kernel technologies and parameter generalization at ductile mode conditions for grinding of optical glasses. An ultra precision machine tool capable of multiply functioning grinding, cutting, lapping or polishing has been newly developed for the ductile-mode grinding of hard-brittle materials. The key components built in the system are inclusive of the force transducer for sub-mN measurement and the PZT actuator for precise positioning. Through the grinding tests and scratching tests, the machining parameters governing the brittle-to-ductile transition have been established for a series of glasses. It also reveals a fact that the critical depth in grinding is thereabouts six times bigger than the critical depth in indentation and seven times than in scratching., SPIE-INT SOC OPTICAL ENGINEERING

  • Study on ultra-precision machining of ceramics for optical components
    H Eda; J Shimizu; LB Zhou, A machining system was developed, to achieve ductile-regime machining of ceramics and glasses for optical components. The machine tool is capable of cutting, grinding, lapping or polishing hard and brittle materials in ductile-regime. As a key component in building the system, giant magnetostrictive alloys with large output power and outstanding elongation are employed to comprise an ultra-precision actuator. The actuator can be used as a high frequency vibration actuator as well as a fine positioning device. The actuator was made of newly developed composition material. In this paper, the results of the actuator used as a high-accuracy positioning device in grinding processes are presented. Various kinds of ceramic materials for optical components were subjected to experiments. The results indicate that the newly developed machine tool is capable of realizing ductile-regime process., SPIE-INT SOC OPTICAL ENGINEERING

  • Powder metallurgic giant magnetostrictive material and its applications in micro-actuator and micro-sensors
    H Eda; T Mori; L Zhou; K Kubota; J Shimizu, In this research, the authors have proposed and developed a new manufacturing process for giant magnetostrictive material (GMM) by using powder metallurgic technique. The results obtained in this paper have verified that the powder metallurgic GMM is quite comparable to that made by the well-established Bridgman Method, in terms of large magneto strain, low hysteresis and high repeatability, and yet at one-third cost. More important is that the powder metallurgy is able to achieve a near-net-shape product regardless to the complexity of the geometry and dimension of the size. It opens new possibilities to miniaturize the sensors and actuators down to millimeter or sub-millimeter scale.
    Using the Joule effect and the inverse Wiedemann effect, a GMM pump and torque sensor have developed in this research to show the potential usage of the powder metallurgic GMM in practical applications., SPIE-INT SOC OPTICAL ENGINEERING

  • 最先端工作機械における基本技術の開発および延性モード研削実験における研削抵抗の一般化
    Lotfi Chouanine; Hiroshi Eda; Jun Shimizu, This paper is an overview of development of Kernel technology and generalization of grinding forces under ductile mode grinding of polycrystal, amorphous, and strengthened glasses. The experiments have been conducted out by a newly developed multi-purpose ultra precision machine tool and system technology (MUPMT) capable of grinding, cutting, lapping, or polishing of hard and brittle materials under ductile-mode conditions. The key components in building this machining system are well described in this paper. The microplasticity zone (depth of cut X feed X machining width) can be set with the positioning accuracy of 1 nm by the PZT or GMA actuators. Furthermore, in order to measure the forces in the grinding and thrust directions a two parallel plates type force sensor with 0. 01 mN of resolution has been newly trial manufactured and equipped with the MUPMT. The relationship between machining parameters and microcracks was examined and brittle to ductile grinding transition has been established for a given type of glass. Besides, a comparison of the recent grinding results and a results of diamond indentation-scratching experiments of previous work done by the authors has shown that the critical depth in grinding is thereabouts six times bigger than the critical depth in indentation and seven times than in scratching., JAPAN SOC PRECISION ENG

  • Molecular dynamics simulation of friction on the atomic scale
    J Shimizu; H Eda; M Yoritsune; E Ohmura, Several molecular dynamics simulations are performed, in order to clarify the atomic-scale stick-slip phenomenon which is commonly observed in the surface measurement using an atomic fine microscope (AFM). In the molecular dynamics simulations, a specimen and a slider are assumed to consist of monocrystalline copper and rigid diamond, respectively, and a Morse potential is postulated between a pair of atoms. Atomic behavior in a plane corresponding to the (111) crystal plane is simulated, dealing with a planar strain problem where the effect of the three-dimensional interatomic force and the spring constant of the AFM cantilever are also taken into consideration. Influence of the cantilever stiffness and dynamics of the specimen surface atoms on the atomic-scale stick-slip phenomenon are investigated. The simulation confirms that the atomic-scale stick-slip phenomenon can be expressed by a molecular dynamics simulation and that the stick-slip phenomenon of the surface atoms of the specimen affects the stick-slip phenomenon of the spring force. These results indicate that molecular dynamics simulation has an advantage in deciding the spring constant of cantilevers., IOP PUBLISHING LTD

  • Analytical study on ductile-regime scratching of glasses using sharply pointed tip diamond indenter
    L Chouanine; H Eda; J Shimizu, This paper describes the feasibility of the ductile mode scratching of optical glasses by a sharply pointed tip diamond indenter. Scratching experiments were carried out with computer controlled nanoindentation-hardness apparatus equipped with trial manufactured parallel plate type force sensor, PZT actuators and mounted in a vacuum chamber of scanning electron microscope. It was found that at low normal loads P < 0.1 mN cracks do not occur on the surfaces of TRC5, GOE91, BK7, SK7, F6 and KzF6, while at loads P > 0.1 mN lateral cracks were well observed. The fracture mechanism of the scratching test is well described in this study by the microplasticity zone of the hypothetically stress-strain diagram for brittle materials. The coefficient of proportionality between the mean pressure on a diamond tip during scratching and the static pressure during indentation has been determined experimentally., JAPAN SOC PRECISION ENG

  • Analysis of sliding mechanism using molecular dynamics: Friction process               
    Jun Shimizu; Etsuji Ohmura; Hiroshi Eda, The analysis of the mechanism of sliding friction without formation of wear particles was performed at the contact between the surface of the test specimen and a slider using molecular dynamics. A two-dimensional analysis was performed in the case where the spring constant of the AFM cantilever was infinite. The following conclusions were made: (1) Changes in the normal load, the friction force and the coefficient of friction were of a complex nature due to the vibration of the atomic lattice of a specimen. When determining the autocorrelation function, it was clear that the period of fundamental wave was equal to the shortest distance between specimen atoms, and the approximation using the Fourier series indicated that the above changes were averaged. (2) The stick-slip behavior of the friction force was due to the displacement of specimen surface atoms in the direction of slider advancement. During the transition of the slip movement to the sticking motion, a negative friction force was generated on the slider. (3) The relative speed of specimen atoms relative to that of the slider during the slip movement was high in materials with a high elastic coefficient and the observation of the stick-slip behavior showed that the sliding speed of the slider increased to the same extent.
