Patent ID: 8841756

Claim:
A semiconductor device formed using a low pressure, highly nonequilibrium epitaxial growth technique capable of forming single or nearly single atomic layers comprising: a substrate comprising a (001) oriented surface; a patterned dielectric layer disposed on the (001) oriented surface of the substrate, wherein the patterned dielectric layer exposes a portion of the substrate; and an epitaxial layer formed, using a low pressure, highly nonequilibrium epitaxial growth technique capable of forming single or nearly single atomic layers, on the portion of the substrate exposed by the patterned dielectric layer and formed above a portion of the patterned dielectric layer, wherein the epitaxial layer comprises a first vertical sidewall formed above the portion of the patterned dielectric layer, the first vertical sidewall comprising a {110} oriented facet and wherein the epitaxial layer and the substrate are formed of a same material, and wherein the epitaxial layer comprises a Group III-V material.
