Abstract:
A semiconductor structure includes a substrate, at least one first gate structure, at least one first spacer, at least one source drain structure, at least one conductive plug, and at least one protection layer. The first gate structure is present on the substrate. The first spacer is present on at least one sidewall of the first gate structure. The source drain structure is present adjacent to the first spacer. The conductive plug is electrically connected to the source drain structure. The protection layer is present between the conductive plug and the spacer.

Claim (Index 8):
A method comprising:\n forming a gate structure over a substrate; forming a hard mask over the gate structure; forming a spacer on a sidewall of the gate structure and a sidewall of the hard mask; forming a source/drain structure over the substrate and adjacent the spacer; forming a first dielectric layer over the source/drain structure and along a sidewall of the spacer; etching the first dielectric layer to form a recess, the recess exposing the sidewall of the spacer and a portion of the first dielectric layer over the source/drain structure; forming a second dielectric layer on sidewalls and a bottom of the recess; etching the second dielectric layer and the portion of the first dielectric layer to extend the recess toward the source/drain structure and to form an extended recess; and filling the extended recess with a conductive material.
