Abstract:
Methods for the repair of damaged low k films are provided. In one embodiment, the method comprises providing a substrate having a low k dielectric film deposited thereon, and exposing a surface of the low k dielectric film to an activated carbon-containing precursor gas to form a conformal carbon-containing film on the surface of the low k dielectric film, wherein the carbon-containing precursor gas has at least one or more Si—N—Si linkages in the molecular structure.
Abstract:
Embodiments disclosed herein generally relate to forming dielectric materials in high aspect ratio features. In one embodiment, a method for filling high aspect ratio trenches in one processing chamber is disclosed. The method includes placing a substrate inside a processing chamber, where the substrate has a surface having a plurality of high aspect ratio trenches and the surface is facing a gas/plasma distribution assembly. The method further includes performing a sequence of depositing a layer of dielectric material on the surface of the substrate and inside each of the plurality of trenches, where the layer of dielectric material is on a bottom and side walls of each trench, and removing a portion of the layer of dielectric material disposed on the surface of the substrate, where an opening of each trench is widened. The sequence repeats until the trenches are filled seamlessly with the dielectric material.
Abstract:
Embodiments disclosed herein generally relate to the processing of substrates, and more particularly, relate to methods for accurate control of film thickness using deposition-etch cycles. Particularly, embodiments of the present disclosure may be used in controlling film thickness during filling high aspect ratio features.
Abstract:
Embodiments disclosed herein generally relate to the processing of substrates, and more particularly, relate to methods for forming a dielectric film. In one embodiment, the method includes placing a plurality of substrates inside a processing chamber and performing a sequence of exposing the substrates to a first reactive gas comprising silicon, and then exposing the substrates to a plasma of a second reactive gas comprising nitrogen and at least one of oxygen or carbon, and repeating the sequence to form the dielectric film comprising silicon carbon nitride or silicon carbon oxynitride on each of the substrates.
