Claim 0:
1. A method for processing a substrate, comprising:
supplying a vaporized precursor from a gas supply into a processing volume of a processing chamber;
supplying activated elements including ions and radicals from a remote plasma source;
energizing the activated elements using RF source power at a first duty cycle to react with the vaporized precursor to deposit an SiNHx film onto a substrate supported on a substrate support disposed in the processing volume;
supplying a first process gas from the remote plasma source while providing RF bias power at a second duty cycle different from the first duty cycle to the substrate support to convert the SiNHx film to an SiOx film;
supplying a process gas mixture formed from a second process gas supplied from the remote plasma source and a third process gas supplied from the gas supply while simultaneously providing the RF source power at the first duty cycle and the RF bias power at the second duty cycle to a showerhead and to the substrate support, respectively, to facilitate SiOx film densification and stabilization and withstand post deposition high temperature/pressure anneal processes; and
annealing the substrate.
