Abstract
A method of reversing Shockley stacking fault expansion includes providing a bipolar or a unipolar SiC device exhibiting forward voltage drift caused by Shockley stacking fault nucleation and expansion. The SiC device is heated to a temperature above 150° C. A current is passed via forward bias operation through the SiC device sufficient to induce at least a partial recovery of the forward bias drift.
