In one embodiment, a method for forming a tungsten-containing material is provided which includes positioning a substrate within a processing chamber containing a lid plate, heating the lid plate to a temperature within a range from about 120° C. to about 180° C., exposing the substrate to a reducing gas during a pre-nucleation soak process, and depositing a first tungsten nucleation layer on the substrate during a first atomic layer deposition process within the processing chamber. The method further provides depositing a tungsten nitride layer on the first tungsten nucleation layer during a vapor deposition process, depositing a second tungsten nucleation layer on the tungsten nitride layer during a second atomic layer deposition process within the processing chamber, and exposing the substrate to another reducing gas during a post-nucleation soak process.

Abstract: Embodiments of the invention provide an improved process for depositing tungsten-containing materials. The process utilizes soak processes and vapor deposition processes to provide tungsten films having significantly improved surface uniformity while increasing the production level throughput. In one embodiment, a method is provided which includes depositing a tungsten silicide layer on the substrate by exposing the substrate to a continuous flow of a silicon precursor while also exposing the substrate to intermittent pulses of a tungsten precursor. The method further provides that the substrate is exposed to the silicon and tungsten precursors which have a silicon/tungsten precursor flow rate ratio of greater than 1, for example, about 2, about 3, or greater. Subsequently, the method provides depositing a tungsten nitride layer on the tungsten suicide layer, depositing a tungsten nucleation layer on the tungsten nitride layer, and depositing a tungsten bulk layer on the tungsten nucleation layer.
