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 13):
A method for forming a contact plug, the method comprising:\n depositing a dielectric layer over a substrate; patterning an opening in the dielectric layer, the opening exposing a portion of the substrate; depositing a diffusion barrier layer in the opening; depositing a conductive liner on sidewalls and a bottom surface of the diffusion barrier layer, wherein, as deposited, the conductive liner is thinner on the sidewalls of the diffusion barrier layer than on the bottom surface of the diffusion barrier layer; and depositing a conductive core in the opening over the conductive liner, wherein the conductive core and the conductive liner have different material compositions.
