Abstract:
Embodiments of a silicon carbide (SiC) device are provided herein. In some embodiments, a silicon carbide (SiC) device may include a gate electrode disposed above a SiC semiconductor layer, wherein the SiC semiconductor layer comprises: a drift region having a first conductivity type; a well region disposed adjacent to the drift region, wherein the well region has a second conductivity type; and a source region having the first conductivity type disposed adjacent to the well region, wherein the source region comprises a source contact region and a pinch region, wherein the pinch region is disposed only partially below the gate electrode, wherein a sheet doping density in the pinch region is less than 2.5×1014 cm−2, and wherein the pinch region is configured to deplete at a current density greater than a nominal current density of the SiC device to increase the resistance of the source region.
