Research area

Focusing on the wide-gap semiconductor substrates, recently drawing attentions as next generation green device such as SiC, GaN, Diamond, etc., a study on the high efficiency polishing process will be conducted to process above hard-to-process materials to an atomic order high quality while leveraging the singular characteristics inherent in such materials. Specifically, with respect to the various component technologies and processing consumables such as pads/tools and slurries/abrasive, used in each phase of the rough, intermediate and finishing processes, we will carry out a thorough investigation to achieve optimized parameters, and then to establish elemental technologies in which processing consumables are integrated and reciprocally employed. The goal is to realize an innovative processing system, equipped with the optimized and integrated elemental technologies. Furthermore, we have developed “novel plasma fusion CMP® machine” combining CMP and plasma-CVM. Technologies and products obtained in the respective area of the research will be elaborated for the commercial use, contributing to the promotion of green device technologies into practical use.
