Images and spectra of light emission from 4H SiC MOSFETs with and without NO annealing have been studied. The emission is induced by driving the channel between accumulation and inversion. By varying the pulse train to the gate, the flow of electrons into the channel can be tracked. The electron flow in the NO-annealed MOSFEETs is an order of magnitude faster than the flow in the control MOSFETs without the anneal. Time resolved spectra allow emission processes from the interface and bulk to be separated, but do not exhibit significant differences between the MOSFETs with and without NO annealing.
