Abstract:
Methods for seam-less gapfill comprising depositing a film in a feature, treating the film to change some film property and selectively etching the film from the top surface are described. The deposition, treatment and etching are repeated to form a seam-less gapfill in the feature.

Claim (Index 13):
A processing method comprising:\n providing a substrate surface having a feature thereon, the feature having sidewalls and a bottom; depositing a silicon film in the feature and on the substrate surface; exposing the silicon film to a treatment to modify a structure, composition or morphology of the silicon film, the treatment comprising exposure to one or more of Ar, He or H 2 ; etching the film from the substrate surface using one or more of H 2 , HCl or Cl 2  to remove substantially all of the film from the substrate surface and leaving at least some of the film in the feature; and repeating the deposition, treatment and etching to fill the feature.
