Abstract:
Methods of forming a differential layer, such as a Contact Etch Stop Layer (CESL), in a semiconductor device are described herein, along with structures formed by the methods. In an embodiment, a structure includes an active area on a substrate, a gate structure over the active area, a gate spacer along a sidewall of the gate structure, and a differential etch stop layer. The differential etch stop layer has a first portion along a sidewall of the gate spacer and has a second portion over an upper surface of the source/drain region. A first thickness of the first portion is in a direction perpendicular to the sidewall of the gate spacer, and a second thickness of the second portion is in a direction perpendicular to the upper surface of the source/drain region. The second thickness is greater than the first thickness.

Claim (Index 7):
The method of  claim 6 , wherein:\n the first one or more precursors include a first precursor that is not included in the second one or more precursors; during the first exposure, the first precursor reacts with an upper surface and a sidewall surface of the device structure, the upper surface of the device structure having a horizontal component; the upper surface on the device structure that is activated is the reacted upper surface of the device structure; and the second one or more precursors include a second precursor that is not included in the first one or more precursors.
