Patent ID: 7977154

Claim:
A method of making a semiconductor device, the method comprising: forming a selective epitaxial growth SEG mask on the surface of a SiC substrate; forming at least one window opening in the SEG mask to expose the surface of the SiC substrate; forming at least one SEG mesa having at least a top, a bottom, and sidewalls in the window opening in the SEG mask and disposed on the SiC substrate by selective epitaxial growth; and forming at least one device region by a self-aligned technique comprising forming at least one contact, wherein forming the at least one contact comprises forming a self-aligned silicide using a portion of the SEG mask as a mask for the self-aligned silicide formation; wherein the at least one SEG mesa comprises at least one SiC layer of selected conductivity type, doping level, and doping depth distribution and wherein the selective epitaxial growth is by halo-carbon low-temperature epitaxial growth.
