Abstract:
A method includes forming a dummy gate stack on a substrate, forming a spacer layer on the dummy gate stack, forming an etch stop layer over the spacer layer and the dummy gate stack, the etch stop layer comprising a vertical portion and a horizontal portion, and performing a densification process on the etch stop layer, wherein the horizontal portion is denser than the vertical portion after the densification process The method also includes forming an oxide layer over the etch stop layer, performing an anneal process on the oxide layer and the etch stop layer, wherein the vertical portion has a greater concentration of oxygen than the horizontal portion after the anneal process.

Claim (Index 15):
A method comprising:\n forming a fin on a substrate; forming a gate stack on the fin; forming spacers on sidewalls of the gate stack; forming epitaxial source/drain regions adjacent the spacers; forming a dielectric layer extending over the spacers and over the epitaxial source/drain regions; performing a plasma process on first portions of the dielectric layer, wherein after performing the plasma process the first portions of the dielectric layer have a greater density than second portions of the dielectric layer; and performing an anneal process on the dielectric layer, wherein after performing the anneal process the first portions of the dielectric layer have a smaller concentration of oxygen than the second portions.
