Abstract:
An embodiment contact plug includes a bilayer structure and a diffusion barrier layer on a sidewall and a bottom surface of the bilayer structure. The bilayer structure includes a conductive core and a conductive liner on a sidewall and a bottom surface of the conductive core. In the embodiment contact plug, the conductive liner comprises cobalt or ruthenium.

Claim (Index 1):
A device comprising:\n a semiconductor substrate; a silicide region in the semiconductor substrate; a dielectric layer over the semiconductor substrate; a conductive film extending through the dielectric layer; and a contact plug extending through the dielectric layer to the silicide region, wherein the contact plug comprises:\n a diffusion barrier layer contacting and having a different material composition than the conductive film, the conductive film is disposed between the diffusion barrier layer and the dielectric layer, the diffusion barrier layer further contacting the silicide region; \n a conductive liner contacting a sidewall and a top surface of the diffusion barrier layer, the conductive liner comprises cobalt or ruthenium, and the conductive liner has a different material composition than the diffusion barrier layer; and \n a conductive core contacting a sidewall and a top surface of the conductive liner, the conductive core has a different material composition than the conductive liner.
