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 2):
The method of  claim 1 , wherein forming the barrier layer comprises:\n depositing a barrier layer on the sidewalls and the exposed conductive region of the opening; depositing a spacer material in the opening having the barrier layer; ashing a portion of the spacer material to form an upper opening that extends downward from an upper surface of the dielectric layer to an upper surface of an unashed portion of the spacer material; removing the barrier layer in the second opening to expose the sidewalls above the unashed portion of the spacer material; and ashing the unashed portion of the spacer material from the lower portion of the opening.
