Abstract
Submicron 4H-SiC MOSFETs are attractive for high frequency operation of 4H-SiC integrated circuits. However, the short channel effects, such as threshold voltage lowering, would be induced at the short-channel devices. In this work, short channel effects were investigated with planar and trench 4H-SiC MOSFETs, and the suppression of the short channel effect with the trench structure was achieved.
