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 9):
A semiconductor device comprising:\n a dielectric layer; a contact plug in the dielectric layer, the contact plug comprising:\n a conductive core; \n a conductive liner along sidewalls and a bottom surface of the conductive core, the conductive liner and the conductive core having different material compositions, a first portion of the conductive liner under the conductive core has a first thickness measured between opposing lateral surfaces of the first portion, wherein a second portion of the conductive liner along a sidewall of the conductive core has a second thickness measured between opposing sidewalls of the second portion, wherein the conductive liner has a uniform thickness from a top surface of the conducive core to the bottom surface of the conductive core, and wherein the second thickness is less than the first thickness; and \n a diffusion barrier layer along sidewalls and a bottom surface of the conductive liner, wherein the conductive liner is disposed between the diffusion barrier layer and the conductive core; and \n a silicide region under the dielectric layer, wherein the contact plug extends to the silicide region.
