Accelerated terrestrial neutron irradiations were performed on different commercial SiC power MOSFETs with planar, trench, and double-trench architectures. The results used to calculate the failure cross sections failure-in-time (FIT) rates at sea level. Enhanced gate drain leakage observed in some devices which did not exhibit a destructive during exposure. In particular, mechanism was for planar trench MOSFETs, first showing partial rupture path mostly between gate, similar what previously...
