Outline of Final Research Achievements

We have developed wafer direct bonding process of GaN/Si(111) and Si(100) substrates to realize Si-LSI stacked with GaN power device. The bonded wafer is made it thin by grinding and polishing after bonding. Remaining Si(111) layer is etched by SF6. For heat exhaust layer, impact of hexagonal-BN for heat exhaust performance is simulated and results show that h-BN can reduce temperature by 30 degree compared with SiO2.

Academic Significance and Societal Importance of the Research Achievements

電源の究極の小型化が可能な3次元パワーSoC(Supply on Chip; Si-LSI、パワーデバイス、パワーデバイスを駆動・制御する回路、インダクタ やコンデンサなどのパッシブ部品を1チップに積層)を実現に向けて、(1)異種デバイスの積層技術、(2)3次元パワーSoCに適した排熱技術、(3)シリコン基板や酸化膜付きSi基板の排熱層を組み込む技術、を開発した。これらにより、電源の小型化、高効率化に見通しを得た。これらの結果は、電気エネルギーの高効率利用ができるため、低炭素社会実現に貢献できる。
