Abstract: Methods for forming metal contacts having tungsten liner layers are provided herein. In some embodiments, a method of processing a substrate includes: exposing a substrate, within a first substrate process chamber, to a plasma formed from a first gas comprising a metal organic tungsten precursor gas or a fluorine-free tungsten halide precursor to deposit a tungsten liner layer, wherein the tungsten liner layer is deposited atop a dielectric layer and within a feature formed in a first surface of the dielectric layer of a substrate; transferring the substrate to a second substrate process chamber without exposing the substrate to atmosphere; and exposing the substrate to a second gas comprising a tungsten fluoride precursor to deposit a tungsten fill layer atop the tungsten liner layer.
