Claim 17:
18. A chemical vapor deposition chamber for processing a substrate, comprising:
a substrate support disposed in a processing volume of the chemical vapor deposition chamber;
a remote plasma source coupled to the chemical vapor deposition chamber and configured to provide activated elements to a showerhead in the processing volume;
an RF source power coupled to the showerhead and configured to provide RF source power at a first duty cycle;
an RF bias power source coupled to the substrate support and configured to provide RF bias power at a second duty cycle different from the first duty cycle to the substrate support;
a gas supply coupled to the chemical vapor deposition chamber and configured to supply process gas to the showerhead disposed in the processing volume; and
a controller configured to:
supply a vaporized precursor from the gas supply into the processing volume of the chemical vapor deposition chamber;
supply activated elements including ions and radicals from the remote plasma source;
energize the activated elements using RF source power at the first duty cycle to react with the vaporized precursor to deposit an SiNHx film onto a substrate supported on the substrate support disposed in the processing volume;
supply a first process gas from the remote plasma source while providing RF bias power at the second duty cycle to the substrate support to convert the SiNHx film to an SiOx film;
supply 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
anneal the substrate.
