Abstract:
The subject matter disclosed herein relates to silicon carbide (SiC) power devices and, more specifically, to SiC super-junction (SJ) power devices. A SiC-SJ device includes a plurality of SiC semiconductor layers of a first conductivity-type, wherein a first and a second SiC semiconductor layer of the plurality of SiC semiconductor layers comprise a termination region disposed adjacent to an active region with an interface formed therebetween, an act wherein the termination region of the first and the second SiC semiconductor layers comprises a plurality of implanted regions of a second conductivity-type, and wherein an effective doping profile of the termination region of the first SiC semiconductor layer is different from an effective doping profile of the termination region of the second SiC semiconductor layer.

Claim (Index 12):
A silicon carbide (SiC) super-junction (SJ) device, comprising:\n a first SiC semiconductor layer of a first conductivity-type, wherein the first SiC semiconductor layer comprises a first plurality of implanted regions of a second conductivity-type that form an active region and a termination region of the first SiC semiconductor layer, wherein the termination region of the first SiC semiconductor layer has a first effective doping profile; and at least one second SiC semiconductor layer of the first conductivity-type disposed below the first SiC semiconductor layer and closer to a substrate layer than the first semiconductor layer, wherein the at least one second SiC semiconductor layer includes a second plurality of implanted regions of the second conductivity-type that form a second active region and a second termination region of the at least one second SiC semiconductor layer, wherein the second termination region of the at least one second SiC semiconductor layer has a second effective doping profile that is different from the first effective doping profile.
