Abstract
Techniques for deposition of high-density dielectric films for patterning applications are described. More particularly, a method of processing a substrate is provided. The method includes flowing a precursor-containing gas mixture into a processing volume of a processing chamber having a substrate positioned on an electrostatic chuck. The substrate is maintained at a pressure between about 0.1 mTorr and about 10 Torr. A plasma is generated at the substrate level by applying a first RF bias to the electrostatic chuck to deposit a dielectric film on the substrate. The dielectric film has a refractive index in a range of about 1.5 to about 3.
