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 10):
A method of forming a vertical fin field effect transistor (vertical finFET) with a self-aligned bottom source/drain, comprising:\n forming a protective layer on two or more vertical fins and a doped layer on a substrate, wherein the protective layer has a thickness that covers the facing sidewalls of two adjacent vertical fins of the two or more vertical fins; forming an isolation trench by removing at least a portion of the protective layer and a portion of the doped layer between the facing sidewalls of the two adjacent vertical fins, wherein the isolation trench is laterally offset from each of the two adjacent vertical fins by the thickness of the protective layer; and forming a dielectric spacer in the isolation trench.
