Abstract

In this paper we report an unexpected improvement in the SiC DMOSFET transistor characteristics after a long temperature treatment at 150 C. The evolution of the device characteristics during a TDDB stress is compared to that after an elevated temperature treatment. The improvement in characteristics after storage at high temperature is believed to be due to instabilities caused by the quality of the SiO2/SiC interface and its large density of defects.
