Unusual Bias Temperature Instability in SiC DMOSFET



Zakariae Chbili, Kin P. Cheung, Jason P. Campbell, John S. Suehle, D. E. Ioannou, Aivars Lelis, Sei-Hyung Ryu


We observe an unusual instability in the SiC DMOSFET transistor characteristics. From a series of bias conditions at elevated temperatures, we conclude that a high density of hole traps in the oxide near the SiO2/SiC interface are responsible.
