    Abstract: Methods for depositing a metal layer in a feature definition of a semiconductor device are provided. In one implementation, a method for depositing a metal layer for forming a semiconductor device is provided. The method comprises performing a cyclic metal deposition process to deposit a metal layer on a substrate and annealing the metal layer disposed on the substrate. The cyclic metal deposition process comprises exposing the substrate to a deposition precursor gas mixture to deposit a portion of the metal layer on the substrate, exposing the portion of the metal layer to either a plasma treatment process or hydrogen annealing process and repeating the exposing the substrate to a deposition precursor gas mixture and exposing the portion of the metal layer to either a plasma treatment process or hydrogen annealing process until a predetermined thickness of the metal layer is achieved.

    Abstract: Embodiments of the invention provide methods for forming materials on a substrate used for metal gate and other applications. In one embodiment, a method includes forming a cobalt stack over a barrier layer disposed on a substrate by depositing a cobalt layer during a deposition process, exposing the cobalt layer to a plasma to form a plasma-treated cobalt layer during a plasma process, and repeating the cobalt deposition process and the plasma process to form the cobalt stack containing a plurality of plasma-treated cobalt layers. The method further includes exposing the cobalt stack to an oxygen source gas to form a cobalt oxide layer from an upper portion of the cobalt stack during a surface oxidation process and heating the remaining portion of the cobalt stack to a temperature within a range from about 300° C. to about 500° C. to form a crystalline cobalt film during a thermal annealing crystallization process.

    Abstract: A method of gap fill may include depositing a sacrificial Si layer in an opening of a feature and on a field of a substrate. In addition, the method may include depositing a metal layer in the opening and on the field, where at least a portion of the sacrificial Si layer is replaced with the metal layer. The method may also include depositing a metal gapfill material in the opening and on the field directly over the metal layer, where the metal gapfill material completely fills the opening.
