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

Claim 0:
1. A semiconductor device, comprising:
fins patterned in a substrate;
source and drains formed in the fins;
at least one gate disposed over the fins, separated from the source and drains by first spacers, wherein a lower portion of the at least one gate comprises a workfunction-setting metal, and an upper portion of the at least one gate comprises an inner core metal between sidewall portions of an outer metal liner, and wherein the outer metal liner is recessed in between the first spacers and the inner core metal;
second spacers disposed over the recessed outer metal liner such that the first spacers and the second spacers surround the inner core metal in the upper portion of the at least one gate;
a middle-of-line (MOL) dielectric disposed over the at least one gate and the source and drains; and
a gate contact in the MOL dielectric over the at least one gate, wherein the gate contact lands on the inner core metal, and on the first spacers and the second spacers that surround the inner core metal of the at least one gate.
