Abstract:
A method of forming a vertical fin field effect transistor (vertical finFET) with a self-aligned bottom source/drain, including forming a doped layer on a substrate, forming one or more vertical fins on the doped layer, forming a protective layer on the one or more vertical fins, wherein the protective layer has a thickness, and forming at least one isolation trench by removing at least a portion of the protective layer on the doped layer, wherein the isolation trench is laterally offset from at least one of the one or more vertical fins by the thickness of the protective layer.

Claim (Index 15):
A vertical fin field effect transistor (vertical finFET) having a self-aligned bottom source/drain, comprising;\n two doped layer regions on a substrate; one or more vertical fins on a first of the two doped layer regions, wherein the first doped layer region forms a bottom source drain for the one or more vertical fins; one or more additional vertical fins on a second of the two doped layer regions, wherein the second doped layer region forms a bottom source drain for the one or more additional vertical fins; a dielectric spacer in the substrate between the first doped layer region and the second doped layer region, wherein the dielectric spacer is offset from one of the one or more vertical fins on the first doped layer region and one of the one or more additional vertical fins on the second doped layer region by a width, W 1 ; a first gate structure on the one or more vertical fins on the first doped layer region; and a second gate structure on the one or more additional vertical fins on the second doped layer region, wherein the dielectric spacer extends above the first gate structure and second gate structure.
