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

Claim 0:
1. 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 each arranged in direct contact one on top of another, wherein the first silicide consists of 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 consists of elements of the second top source drain epi and the metal contact,
wherein the metal contact is physically arranged between the second silicide from the second contact liner, and wherein a bottommost surface of the metal contact is entirely below a topmost surface of the second silicide, 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.
