Abstract:
Provided here are methods and manufacturing systems to implant protons into SiC IGBT devices at multiple depths in the drift layer of the SiC IGBT device. Provides are SiC IGBT devices manufactured with process steps including multiple proton implant processes where the SiC IGBT device is irradiated with ion to affect proton implantation into the SiC IGBT device at multiple depths in the drift region to reduced minority carrier lifetime.
