Abstract
Methods and apparatus for depositing a dielectric material include: providing a first gas mixture into a processing chamber having a substrate disposed therein; forming a first remote plasma comprising first radicals in a remote plasma source and delivering the first radicals to an interior processing region in the processing chamber to form a layer of dielectric material in an opening in a material layer disposed on the substrate in a presence of the first gas mixture and the first radicals; terminating the first remote plasma and applying a first RF bias power to the processing chamber to form a first bias plasma; contacting the layer of dielectric material with the first bias plasma to form a first treated layer of dielectric material; and subsequently forming a second remote plasma comprising second radicals in the remote plasma source and delivering the second radicals to the interior processing region in the processing chamber in a presence of a second gas mixture while applying a second RF bias power to the processing chamber to form a second bias plasma, wherein the second radicals and second bias plasma contact the first treated layer of dielectric material to increase a hydrophobicity or a viscosity of the first treated layer of dielectric material.
