Study on Polishing Mechanism of Single Crystal Substrate by UV-Excitation
M. Touge; T. Nagano; T. Tagawa; T. Sakamoto; H. Yokoi; C. Iwamoto; J. Watanabe, Diamond has superior characteristics such as the highest thermal conductivity and dielectric breakdown field, and is expected to be a good candidate material for the next generation semiconductor device. On the other hand, the etching and the mechanical processing are much difficult because of chemical and physical stabilities of diamond. As the device materials must be polished without the crystallographic distortion beneath a polished substrate, the simplified planarization techniques accompanied with high surface quality is intensely required. The ultraviolet rays excited polishing of single crystal diamond substrates has been studied in our laboratory. The UV-polishing characteristics, such as higher polishing rate and superior final surface roughness, have been revealed in these many years. This work will interpret the UV-polishing mechanism to achieve a well-polished diamond substrate satisfied for the requirement of the semiconductor device materials. The effects of the ultraviolet irradiation and processing atmosphere on the polishing rate and surface integrities were carefully examined. The polishing mechanism was discussed using experimental results of the luminous phenomenon, CO gas concentration and TEM observation of abrasion powder. The polishing model based on these discussions was proposed, and high-grade diamond wafer was finally obtained by the UV-polishing under the polishing conditions decided by the proposed polishing model., The Japan Society for Precision Engineering

High resolution transmission electron microscopy of Aluminum/Mo-coated glass substrate interface bonded by ultrasonic wire welding
C. Iwamoto; S. Satonaka; A. Yoshida; T. Nishinaka; K. Yamada, Corresponding, Ultrasonic welding is an attractive joining method, because bonding is quickly obtained without extra heat or welding metal. Thus far, there have been several researches about the bonded interface structure and process of the ultrasonic welding. However, atomic structure analysis of the bonded interface was limited and sometimes controversial results were obtained. Besides, there were only few studies about application of the ultrasonic welding to Al/Glass substrates and detailed bonding mechanism was unclear. In this report, the ultrasonic bonded interface between an Al wire and a Mo coated glass substrate was observed by high resolution transmission electron microscopy and the bonding mechanism was discussed. The bonded sample was cut perpendicular to the interface and, the atomic structure and chemical composition of the cross-section of the sample were analyzed. Grains in a Mo layer on the glass observed before bonding extended perpendicular to the glass substrate and terminated with nano sized pyramids. Structure of Mo grains remained unchanged after the bonding. Around the interface between Al and Mo, several dislocations and Al sub-grains were produced in Al and no intermetallic compounds were observed. Al and Mo lattices were directly connected at the interface. This indicates that dislocations generated at the interface moved to form low angle grain boundaries during a recovery process without intermetallic formation. During the ultrasonic welding process, the pyramids of Mo surface were considered to work effectively to break a native oxide and produce the bonded interface., The Japan Society of Mechanical Engineers

Reaction products at the interface of IN-738/Si3N4 bond
Chen; Y. C.; Iwamoto; C.; Ishida; Y., Corresponding, The purpose of this study was to investigate the interface microstructure and reaction products morphology in solid state diffusion bonding of the silicon nitride/Ni-based superalloy (IN-738). Compounds such as Cr₃Si, Ni₃₁Si₁₂, δ-Ni₂Si and Cr₃Ni₂Si were identified. A precipitated zone which exists between the reaction products and IN-738 works as a diffusion barrier, the reactive elements of IN-738 seem to be almost blocked to contribute to the formation of Cr₃Si, Ni₃₁Si₁₂, δ-Ni₂Si, and Cr₃Ni₂Si. The phenomenon of morphological instability was also explained by Wagner’s model. The faceted phases Cr₃Ni₂Si and δ-Ni₂Si showed an epitaxial growth along with the Si₃N₄ matrix., The Japan Institute of Metals
