Abstract:
Aspects of the present disclosure include a method for forming a contact on a semiconductor device, the semiconductor device including a conductive region disposed over a substrate, the method comprising: depositing a dielectric material on the substrate; forming an opening in the dielectric material to expose the conductive region; forming a barrier layer on a lower surface and sidewalls of the opening in the dielectric material, the barrier layer terminating below an upper surface of the dielectric material and surrounding a lower portion of the opening; depositing cobalt in the lower portion of the opening, the cobalt terminating at an upper surface of the barrier layer; depositing tungsten to fill the opening to at least the upper surface of the dielectric material; and planarizing the upper surface of the dielectric material with the tungsten in the opening.

Claim (Index 14):
The method of  claim 13 , wherein an upper surface of the first tungsten layer is substantially coplanar with the upper surface dielectric layer and an upper surface of the second tungsten layer within the opening, after the planarizing.
