This paper aims to study the SiC power MOSFETs robustness to Electrostatic Discharge (ESD), by photon emission using spectral photoemission technique (SPE). Investigations in photoemission PE reveal the degradation signature. SPE analyses are performed to identify the failure mechanism. The ESD degradation is seems to be related to oxide degradation. C-V analyses are conducted to prove this hypothesis.
