摘要

Multidimensional device structures can improve the typical performance trade-off of semiconductor power transistors. In this paper, the on-state, reverse, and short-circuit performance of a SiC quasi-planar trench MOSFET are compared to those of a classical planar device through advanced 3-D TCAD simulations.
