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

Claim 16:
17. A semiconductor device, comprising:
a substrate;
a semiconductor fin protruding from the substrate and extending upwardly in a first direction;
a source/drain (S/D) feature including a first portion over the semiconductor fin and a second portion over the first portion, wherein a top surface of the first portion of the S/D feature bends downward towards the substrate in a cross-sectional plane perpendicular to a lengthwise direction of the semiconductor fin, wherein the S/D feature comprises a first slanted sidewall and a second slanted sidewall, and wherein the first and second slanted sidewalls intersect; and
a conductive feature disposed on the S/D feature, wherein a portion of the conductive feature is landed on the first slanted sidewall and a bottom of the conductive feature is closer to the substrate than an intersected portion of the first and second slanted sidewalls, the conductive feature comprises a sidewall extending in the first direction, and a bottom of the sidewall is lower than a topmost portion of the S/D feature and spaced apart from the bottom of the conductive feature.
