  • Publication number: 20230268223
    Abstract: Semiconductor devices and methods of manufacturing the semiconductor devices are described herein. A method includes forming a gate electrode, a gate electrode contact layer over the gate electrode, forming a dielectric layer over the gate electrode contact layer, and performing an etch through the dielectric layer, the etch forming an opening that exposes the gate electrode contact layer. The method further includes performing a post-etch treatment on the opening formed by the etch process by exposing the opening to a plasma. The method further includes forming gate electrode contacts in the openings after the post-etch treatment by a bottom-up deposition process.

  • Publication number: 20220293741
    Abstract: A semiconductor device and method of manufacture are provided which utilize a remote plasma process which reduces or eliminates segregation of material. By reducing segregation of the material, overlying conductive material can be deposited on a smoother interface. By depositing on smoother interfaces, overall losses of the deposited material may be avoided, which improves the overall yield.
