Abstract:
Devices and methods that include for configuring a profile of a liner layer before filling an opening disposed over a semiconductor substrate. The liner layer has a first thickness at the bottom of the opening and a second thickness a top of the opening, the second thickness being smaller that the first thickness. In an embodiment, the filled opening provides a contact structure.

Claim (Index 10):
A method comprising:\n providing a substrate having a gate structure and a source/drain region; depositing a dielectric layer over the substrate, the gate structure, and the source/drain region; etching a first opening in the dielectric layer exposing a top surface of the gate structure and a second opening in the dielectric layer exposing a top surface of the source/drain region; depositing a first portion of a liner layer in the first opening and the second opening; removing a top region of the first portion of the liner layer from the first opening and the second opening, wherein the top region interfaces a top portion of a sidewall of the first opening and the second opening; and depositing a second portion of the liner layer after removing the top region, wherein the first and second portions of the liner layer provide a first thickness on the top portion of the sidewalls of the first opening and the second opening and a second thickness on a bottom of the first opening and the second opening, the second thickness being greater than the first thickness.
