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 22):
A method of manufacturing a silicon carbide (SiC) super-junction (SJ) device, comprising:\n fabricating a lower SiC semiconductor layer of the SiC-SJ device, comprising:\n forming the lower SiC semiconductor layer having a first conductivity-type on top of a SiC substrate layer; \n fabricating an active region in the lower SiC semiconductor layer by forming a first plurality of implanted regions having a second conductivity-type in a portion of the lower SiC semiconductor layer; and \n fabricating a termination region in the lower SiC semiconductor layer by forming a second plurality of implanted regions having the second conductivity-type in another portion of the lower SiC semiconductor layer adjacent the active region according to a first effective doping profile; and \n fabricating a top SiC semiconductor layer of the SiC-SJ device, comprising:\n forming the top SiC semiconductor layer having the first conductivity-type above the lower SiC semiconductor layer; \n fabricating an active region in the top SiC semiconductor layer by forming a third plurality of implanted regions having the second conductivity-type in a portion of the top SiC semiconductor layer; and \n fabricating a termination region in the top SiC semiconductor layer by forming a fourth plurality of implanted regions having the second conductivity-type in another portion of the top SiC semiconductor layer adjacent the active region according to a second effective doping profile, wherein the first effective doping profile is different from the second effective doping profile.
