    Abstract: Exemplary methods of semiconductor processing may include treating a surface of a substrate with a hydrogen-containing precursor. The substrate may be disposed within a processing region of a semiconductor processing chamber. The methods may include contacting the substrate with a tungsten-containing precursor. The methods may include forming an initiation layer comprising tungsten on the substrate. The methods may include treating the initiation layer with a hydrogen-containing precursor. The methods may include forming a plasma of the tungsten-containing precursor and a carbon-containing precursor. Hydrogen in the plasma may be limited to hydrogen included in the carbon-containing precursor. The methods may include forming a tungsten-containing hardmask layer on the initiation layer.

    Abstract: A computer program storage product includes instructions for forming a fin field-effect-transistor. The instructions are configured to perform a method. The method includes implanting a dopant into an exposed portion of a semiconductor substrate within a cavity. The cavity is formed in a dielectric layer on the semiconductor substrate. The cavity exposes the portion of the semiconductor substrate within the cavity. A semiconductor layer is epitaxially grown within the cavity atop the dopant implanted exposed portion of the semiconductor substrate. A height of the cavity defines a height of the epitaxially grown semiconductor.
