Abstract

We present an extended mobility model that accounts for anisotropic current transport along non-equivalent crystallographic axes for a given wafer orientation. Using this model we investigated the influence of anisotropic effects on the device characteristics of 4H- and 6H-SiC transistor structures (JFET, UMOS, DIMOS). Dependent on the polytype of the underlying material and the device structure, large variations in the device behavior may result from anisotropic mobility. This influence is strongest in the 6H-SiC DIMOS.
