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

Claim 15:
16. 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 one on top of another, wherein the first contact is directly on the first contact liner, the first contact liner is directly on the first silicide, and the first silicide is directly on the first top source drain epi; 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 each arranged one on top of another, wherein the second contact is directly on the second contact liner, the second contact liner is directly on the metal contact, the metal contact is directly on the second silicide, and the second silicide is directly on the first top source drain epi,
wherein the first contact liner and the second contact liner comprise identical elements.
