Abstract
A semiconductor structure includes a semiconductor fin extending from a substrate, a source/drain (S/D) feature disposed over the semiconductor fin, a silicide layer disposed over the S/D feature, where the silicide layer extends along a sidewall of the S/D feature, and an etch-stop layer (ESL) disposed along a sidewall of the silicide layer.
