FORMATION OF CONTACTS FOR SEMICONDUCTOR DEVICES
Last updated:
Abstract:
A method for fabricating a semiconductor device includes forming top source/drain contact material on top source/drain material disposed on one or more fins of a base structure, and subtractively patterning the top source/drain contact material to form at least one top source/drain contact. The at least one top source/drain contact has a positive tapered geometry. The method further includes cutting exposed end portions of the top source/drain material to form at least one top source/drain region underneath the at least one top source/drain contact.
