Patent ID: 8685823

Claim:
A method for forming a field effect transistor device, the method comprising: forming a nanowire suspended above a substrate; forming a dummy gate stack on a portion of the substrate and around a portion of the nanowire; removing exposed portions of the nanowire; epitaxially growing nanowire extension portions from exposed portions of the nanowire; depositing a layer of semiconductor material over exposed portions of the substrate, the dummy gate stack and the nanowire extension portions; removing portions of the semiconductor material to form sidewall contact regions arranged adjacent to the dummy gate stack and contacting the nanowire extension portions; forming a silicide on exposed portions of the sidewall contact regions; depositing a capping layer over the silicide, and exposed portions of the dummy gate stack and the substrate; removing portions of the capping layer to expose a portion of the dummy gate; removing a portion of the dummy gate to expose the nanowire; depositing a dielectric layer over exposed portions of the nanowire; depositing conductive layer over the dielectric layer; and forming a capping layer over exposed portions of the conductive layer.
