Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A semiconductor device, comprising:
a fin structure;
a first conductive structure over the fin structure;
a metal cap, substantially overlapping an entire top surface of the first conductive structure, comprising an upper surface that has a generally concave shape and that is at a first height, at a lowest portion of the metal cap, and a second height, at a highest portion of the metal cap;
a dielectric structure above the metal cap; and
a second conductive structure above the first conductive structure,
wherein sidewalls of the first conductive structure are aligned with sidewalls of the second conductive structure, and
wherein the sidewalls of the second conductive structure are in direct contact with sidewalls of the metal cap.
