Outline of Final Research Achievements

In this project, we propose a method to identify SiC-MOS interface defects and to reduce the defects at the SiC/SiO2 interface based on first-principles calculations. In this study, two candidate defects at the SiC-MOS interface were successfully identified: one is an intrinsic defect in SiC due to the wave function at the lower end of the conduction band of SiC, and the other is a carbon-related defect precipitated at the interface. In particular, we proposed an oxide film formation method without thermal oxidation as a method to propose carbon-related defects precipitated at the interface. The experimental results showed that the density of interfacial defects could be reduced to one-tenth.

Academic Significance and Societal Importance of the Research Achievements

SiC/SiO2界面に現れる欠陥の特定とその低減は、SiC-MOSデバイス特性の改善において重要な研究課題である。本課題では、理論計算に基づき、界面欠陥の特定とその低減法を提案した。特に、その低減法は実験によって有効性が示され、界面欠陥密度の大幅な低減に成功した。ここで開発された技術は、省エネ社会実現に大きく貢献するものと考えられる。この研究課題は、パワー半導体デバイスにおける日本のプレゼンス拡大に大きく貢献するものと考える。
