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 20):
A method comprising:\n (a) 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; (b) exposing the substrate to a silicon precursor and a reactant to deposit 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, the silicon precursor comprising one or more of silane, disilane, trisilane, tetrasilane, a higher order silane or dichlorosilane, the reactant comprising a plasma comprising one or more of hydrogen or nitrogen, the first film formed to a depth in the range of about 1 \u212b to about 50 \u212b; (c) exposing the substrate to an etchant comprising a plasma comprising one or more of H 2 , HCl or Cl 2  to etch the first film from the sidewalls of the feature; (d) treating the first film in the bottom of the feature to form a second film comprising one or more of silicon oxide, silicon nitride or silicon oxynitride in the feature, treating the film comprising exposing the substrate to a plasma comprising one or more of Ar, He, H 2 , O 2 , N 2 O, O 3  or H 2 O, NH 3 , N 2 ; and (e) repeating (b) through (d) to fill the feature.
