Abstract

Embodiments of the present disclosure generally relate to methods for cleaning a chamber comprising introducing a gas to a processing volume of the chamber, providing a first radiofrequency (RF) power having a first frequency of about 40 MHz or greater to a lid of the chamber, providing a second RF power having a second frequency to an electrode disposed in a substrate support within the processing volume, and removing at least a portion of a film disposed on a surface of a chamber component of the chamber. The second frequency is about 10 MHz to about 20 MHz.
