Classification: CPC H | IPC H

Claim 7:
8. A processing method comprising:
setting a plasma power and a temperature of a pedestal in a processing chamber to greater than or equal to −20° C. and less than or equal to 60° C., the pedestal comprising radio frequency (RF) capability and a cooling feature;
exposing a substrate on the pedestal, the substrate comprising a surface structure including a metal bottom surface comprising one or more of tungsten (W), cobalt (Co), or ruthenium (Ru), exposed dielectric sidewall surfaces comprising dielectric material, and a field of dielectric, to a plasma treatment in the processing chamber to remove chemical residual and/or impurities from the metal bottom surface, the exposed dielectric sidewalls comprising dielectric material, and the field of the dielectric and/or repair surface defects in the exposed dielectric sidewall surfaces comprising dielectric material and/or the field of the dielectric, wherein the plasma treatment comprises an oxygen plasma; and
exposing the substrate to at least one precursor of the metal to selectively form a metal film on the substrate by enhancing selective metal growth on the metal bottom surface.
