2017 29th International Symposium on Power Semiconductor Devices and IC's (ISPSD).
Advanced metal/high-k gate stack technology for SiC-based power MOSFET was demonstrated. We found that the Hf incorporation into aluminum oxynitride (HfAlON gate insulator) combined with TIN electrode effectively improves the stability of threshold v
