Abstract:
Methods for gapfill of high aspect ratio features are described. A first film is deposited on the bottom and upper sidewalls of a feature. The first film is etched from the sidewalls of the feature and the first film in the bottom of the feature is treated to form a second film. The deposition, etch and treat processes are repeated to fill the feature.

Claim (Index 17):
A method comprising:\n providing a substrate having a substrate surface with a plurality of features formed therein, each feature extending a distance from the substrate surface and having a bottom and at least one sidewall; depositing a first film comprising silicon in the at least one feature so that the first film forms on the bottom of the feature and on the sidewalls of the feature near the substrate surface; etching the first film from the sidewalls of the feature; and treating the first film in the bottom of the feature to form a second film in the feature, the second film comprising one or more of silicon oxide, silicon nitride or silicon oxynitride.
