Abstract:
Exemplary semiconductor processing methods may include providing one or more deposition precursors to a processing region of a semiconductor processing chamber, the deposition precursors may be or include a tungsten-containing precursor. A substrate may be disposed within the processing region of the semiconductor processing chamber. The methods may include forming a plasma of the one or more deposition precursors in the processing region. The plasma may be at least partially formed by an RF power operating at less than or about 3,000 W and at a pulsing frequency less than or about 100,000 Hz. The methods may include forming a layer of material on the substrate. The layer of material may be or include a tungsten-containing material.
