Patent ID: 11948799
Assignee: APPLIED MATERIALS, INC.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 15:
16. A non-transitory computer readable medium comprising instructions that when executed by processing circuitry cause the processing circuitry to:
send first control signals to a proton implant tool to cause the proton implant tool to process, with a first proton implant process, a silicon carbide (SiC) semiconductor device to implant protons into a drift layer of the SiC semiconductor device at a first depth, wherein the SiC semiconductor device further includes an upper structure over the drift layer and a bottom metal contact below the drift layer; and
send second control signals to the proton implant tool to cause the proton implant tool to process, with a second proton implant process, the SiC semiconductor device to implant protons into the drift layer of the SiC semiconductor device at a second depth different than the first depth, wherein the upper structure and the bottom metal contact are formed before the first proton implant process and the seocnd proton implant process.
