Patent ID: 8921825

Claim:
A field effect transistor device comprising: a nanowire; a gate stack comprising: a gate dielectric layer disposed on the nanowire; a gate conductor layer disposed on the gate dielectric layer and a substrate; epitaxial nanowire extension portions grown on opposing ends of the nanowire, the epitaxial nanowire extension portions in contact with the gate stack; and amorphous sidewall contact portions disposed on opposing ends of the gate stack, the amorphous sidewall contact portions in electrical conductive contact with the epitaxial nanowire extension portions, wherein the amorphous sidewall contact portions surround the epitaxial nanowire extension portions, the amorphous sidewall contact portions and the epitaxial nanowire extension portions each have a uniform width, and wherein the uniform width of the amorphous sidewall contact portions is the same as the uniform width of the epitaxial nanowire extension portions.
