摘要: We have developed AlON high-k gate dielectric technology that can be easily implemented into both planar and trench SiC-based MOSFETs. On the basis of electrical characterization numerical simulation, thickness ratio layer to SiO 2 interlayer nitrogen content in film were carefully optimized enhance device performance reliability.
