Abstract

The switching characteristics of silicon carbide (SiC) metal-oxide-semiconductor field-effect transistor (MOSFET) power devices of different structures were experimented after exposure to a gamma irradiation environment. The experimental results for on-state were studied. The comparisons are shown for SiC MOSFET power devices with planar, trench and double trench structures tested for total ionizing dose (TID). A higher degradation of the switching characteristics was observed for the double trench structure. The physical mechanisms for these switching characteristics variations were analyzed. In addition, they were confirmed by technology computer-aided design (TCAD) simulation.
