    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.
