Abstract:
Exemplary methods for removing cobalt material may include flowing a chlorine-containing precursor into a processing region of a semiconductor processing chamber. The methods may include forming a plasma of the chlorine-containing precursor to produce plasma effluents. The methods may also include contacting an exposed region of cobalt with the plasma effluents. The exposed region of cobalt may include an overhang of cobalt on a trench defined on a substrate. The plasma effluents may produce cobalt chloride at the overhang of cobalt. The methods may include flowing a nitrogen-containing precursor into the processing region of the semiconductor processing chamber. The methods may further include contacting the cobalt chloride with the nitrogen-containing precursor. The methods may also include recessing the overhang of cobalt.

Claim (Index 20):
The method of producing a gap-free cobalt fill of  claim 14 , wherein the cobalt is deposited on a metallic nitride liner formed within the trench.
