Abstract: Methods and apparatus for processing a substrate are provided herein. For example, a method includes supplying a vaporized precursor into a processing volume, 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 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 providing RF bias power at the second duty cycle to the substrate support, and annealing the substrate.

Abstract: Methods and apparatus for forming an integrated circuit structure, comprising: delivering a process gas to a process volume of a process chamber; applying low frequency RF power to an electrode formed from a high secondary electron emission coefficient material disposed in the process volume; generating a plasma comprising ions in the process volume; bombarding the electrode with the ions to cause the electrode to emit electrons and form an electron beam; and contacting a dielectric material with the electron beam to cure the dielectric material, wherein the dielectric material is a flowable chemical vapor deposition product. In embodiments, the curing stabilizes the dielectric material by reducing the oxygen content and increasing the nitrogen content of the dielectric material.
