Abstract:
Semiconductor device structures comprising a spacer feature having multiple spacer layers are provided. In one example, a semiconductor device includes an active area on a substrate, the active area comprising a source/drain region, a gate structure over the active area, the source/drain region being proximate the gate structure, a spacer feature having a first portion along a sidewall of the gate structure and having a second portion along the source/drain region, wherein the first portion of the spacer feature comprises a bulk spacer layer along the sidewall of the gate structure, wherein the second portion of the spacer feature comprises the bulk spacer layer and a treated seal spacer layer, the treated seal spacer layer being disposed along the source/drain region and between the bulk spacer layer and the source/drain region, and a contact etching stop layer on the spacer feature.

Claim (Index 13):
