Patent ID: 11908907
Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATION
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 8:
9. A semiconductor device comprising:
a first Vertical Field Effect Transistor (VFET) comprising a first top source drain epi, a first silicide, a first contact liner and a first contact, wherein the first silicide comprises elements of the first top source drain epi and the first contact liner; and
a second VFET comprising a second top source drain epi, a second silicide, a metal contact, a second contact liner and a second contact, wherein the second silicide comprises elements of the second top source drain epi and the metal contact,
wherein a bottommost surface of the second liner is entirely above a topmost surface of the metal contact, and wherein a bottommost surface of the first contact liner directly contacts a top surface of the first silicide, and wherein the first contact liner and the second contact liner comprise identical elements.
