Claim:
1. A method of depositing a silicon oxide film on a surface of a substrate in a single or multi-station reaction chamber, the method comprising: (a) flowing a silicon-containing reactant in vapor phase into the reaction chamber under conditions allowing the silicon-containing reactant to adsorb onto the surface of the substrate; (b) after (a), flowing an oxygen-containing reactant in vapor phase into the reaction chamber, and exposing the surface of the substrate to plasma to drive a surface reaction between the silicon-containing reactant and the oxygen-containing reactant to form the silicon oxide film, (c) repeating (a) and (b) until the silicon oxide film reaches a target thickness; and (d) periodically exposing the surface of the substrate to a plasma treatment comprising:
