Abstract:
A vertical FinFET includes a semiconductor fin formed over a semiconductor substrate. A self-aligned first source/drain contact is electrically separated from a second source/drain contact by a sidewall spacer that is formed over an endwall of the fin. The sidewall spacer, which comprises a dielectric material, allows the self-aligned first source/drain contact to be located in close proximity to an endwall of the fin and the associated second source/drain contact without risk of an electrical short between the adjacent contacts.

Claim (Index 1):
A vertical FinFET device, comprising:\n a fin disposed over a semiconductor substrate; a bottom source/drain region disposed over the semiconductor substrate, where a lower portion of the fin is in contact with the bottom source/drain region; a gate stack disposed over sidewalls of the fin, the gate stack extending laterally over the bottom source/drain region on at least one side of the fin, a top source/drain region disposed over an upper portion of the fin; a top source/drain metallization layer in electrical contact with the top source/drain region; a bottom source/drain metallization layer in electrical contact with the bottom source/drain region; and a sidewall spacer disposed over an endwall of the fin, wherein the sidewall spacer is disposed between the top source/drain metallization layer and the bottom source/drain metallization layer.
