    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.
