摘要： Embodiments are provided for a method to deposit barrier and tungsten materials on a substrate. In one embodiment, a method provides forming a barrier layer on a substrate and exposing the substrate to a silane gas to form a thin silicon-containing layer on the barrier layer during a soak process. The method further provides depositing a tungsten nucleation layer over the barrier layer and the thin silicon-containing layer during an atomic layer deposition process and depositing a tungsten bulk layer on the tungsten nucleation layer during a chemical vapor deposition process. In some examples, the barrier layer contains metallic cobalt and cobalt silicide, or metallic nickel and nickel silicide. In other examples, the barrier layer contains metallic titanium and titanium nitride, or metallic tantalum and tantalum nitride.

摘要： Embodiments of the invention provide methods for reducing formation of void-type defects on the surface of a substrate during electrochemical plating. Embodiments of the invention provide methods to improve the wetting of a substrate surface prior to immersion and thereby minimize adhesion of bubbles to the substrate surface during immersion. A thin uniform metal oxide is formed on a metal layer on the substrate immediately prior to substrate immersion. In one aspect, exposing the substrate to an oxygen-containing gas, e.g. air, forms the metal oxide. The oxygen-containing gas may be flowed over the substrate or the substrate may be rotated at a high rate in the presence of an oxygen-containing gas. In another aspect, non-uniform metal oxides are first removed from the substrate in an anneal process and a thin uniform metal oxide is subsequently re-formed. An optimized substrate immersion method may also be used to further reduce void defects.
