Patent ID: 7312128

Claim:
A method for selectively and epitaxially forming a silicon-containing material on a substrate surface, comprising: positioning a substrate comprising a monocrystalline surface and at least a dielectric surface into a process chamber; and performing a deposition sequence comprising: exposing the substrate to a deposition gas to deposit an epitaxial layer on the monocrystalline surface while simultaneously depositing a second material on the dielectric surface, the second material comprising a material selected from the group consisting of a polycrystalline material, an amorphous material, and combinations thereof, wherein the deposition gas comprises a silicon source, a boron dopant source, and at least a carbon source; and subsequently exposing the substrate to an etching gas to etch the second material, wherein the net result of the deposition sequence consists essentially of the epitaxial material selectively grown on the monocrystalline surface.
