US Classification:

438649, 438683, 427255392, 257E21165

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.

438680, 438677, 257E21171, 257E21585

Abstract:

Embodiments of the invention provide an improved process for depositing tungsten-containing materials. The process utilizes soak processes and vapor deposition processes, such as atomic layer deposition (ALD) to provide tungsten films having significantly improved surface uniformity and production level throughput. In one embodiment, a method for forming a tungsten-containing material on a substrate is provided which includes positioning a substrate within a process chamber, wherein the substrate contains an underlayer disposed thereon, exposing the substrate sequentially to a tungsten precursor and a reducing gas to deposit a tungsten nucleation layer on the underlayer during an ALD process, wherein the reducing gas contains a hydrogen/hydride flow rate ratio of about 40:1, 100:1, 500:1, 800:1, 1,000:1, or greater, and depositing a tungsten bulk layer on the tungsten nucleation layer. The reducing gas contains a hydride compound, such as diborane, silane, or disilane.
