Abstract
Embodiments of the present disclosure generally relate to an apparatus and method for reducing particle generation in a processing chamber. In one embodiment, an apparatus for processing a substrate is disclosed. The apparatus includes a chamber body, a lid assembly disposed above the chamber body, the lid assembly comprising a top electrode and a bottom electrode positioned substantially parallel to the top electrode, a gas distribution plate disposed between a substrate processing region and the lid assembly, and a substrate support disposed within the chamber body, the substrate support supporting having a substrate supporting surface, wherein the top electrode is in electrical communication with a radio frequency (RF) power supply and a DC bias modulation configuration, and the DC bias modulation configuration is configured to operate the top electrode at a constant zero DC bias voltage during a process.
