Abstract:
A semiconductor device and a method for forming the same are provided. The method includes forming a gate structure over a fin structure. The method further includes forming first gate spacers on opposite sidewalls of the gate structure. The method further includes forming source/drain features in the fin structure and adjacent to the first gate spacers. The method further includes performing a surface treatment process on top surfaces of the source/drain features and outer sidewalls of the first gate spacers. The method further includes depositing a contact etch stop layer (CESL) over the source/drain features and the first gate spacers. A first portion of the CESL is deposited over the top surfaces of the source/drain features at a first deposition rate. A second portion of the CESL is deposited over the outer sidewalls of the first gate spacers at a second deposition rate.

Claim (Index 17):
The method for forming a semiconductor structure as claimed in  claim 12 , further comprising:\n forming second gate spacers over the fin structure and the first gate spacers before forming the source/drain features; forming an inter-layer dielectric (ILD) structure over the fin structure, the gate structure, the first gate spacers and the source/drain features; removing the gate structure to form a trench; forming a metal gate structure in the trench; and forming contact plugs over the source/drain features.
