Abstract :
It is well known that SiC can be thermally oxidized to form SiO 2 layers. And Si MOSFET IC´s using thermally grown SiO2 gate dielectrics are the predominant IC technology in the world today. However the SiC/SiO2 interface has not been well characterized as was the case for Si MOS in the early 1960´s. This paper presents data which for the first time characterizes the SiC/SiO2 interface and explains one of the previously unexplained abnormalities observed in the characteristics of SiC MOSFET´s
