Abstract

Embodiments include a method of processing a substrate. In an embodiment, the method comprises flowing one or more source gasses into a processing chamber, and inducing a plasma from the source gases with a plasma source that is operated in a first mode. In an embodiment, the method may further comprise biasing the substrate with a DC power source that is operated in a second mode. In an embodiment, the method may further comprise depositing a film on the substrate.
