Patent ID: 8310013

Claim:
A FinFET device comprising: a substrate of a crystalline semiconductor material having a top surface of a first crystal plane orientation; a fin structure of the crystalline semiconductor material overlying the substrate; a gate structure over a first portion of the fin structure; an epitaxy layer over a second portion of the fin structure, wherein the epitaxy layer includes: a top surface of the epitaxy layer parallel with the top surface of the substrate; and a first surface and a second surface disposed as sidewall surfaces that are perpendicular to the top surface of the epitaxy layer; and wherein the first surface has a second crystal plane orientation, the second crystal plane orientation different than the first crystal plane orientation; wherein the epitaxy layer and underlying fin structure include a source and drain region, the source region being separated from the drain region by the gate structure; and a channel defined in the fin structure from the source region to the drain region, and aligned in a direction parallel to both the first surface of the epitaxy layer and the top surface of the substrate.
