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

Claim 12:
13. A semiconductor device structure, comprising:
a fin structure protruding from a substrate and extending along a first direction;
a gate stack formed over the substrate and extending along a second direction different from the first direction;
a dielectric structure spaced apart from the gate stack along the second direction, wherein the dielectric structure has a slope sidewall surface;
source/drain structures formed at opposite sides of the gate stack along the first direction;
a contact structure formed over the source/drain structures and extending along and in contact with a lower portion of the slope sidewall surface of the dielectric structure; and
a first cap layer vertically overlapping the contact structure and extending along and in contact with an upper portion of the slope sidewall surface of the dielectric structure.
