Abstract
Methods for reducing the contamination of a gas distribution plate are provided. In one embodiment, a method for processing a substrate includes transferring the substrate into a chamber, performing a treating process on the substrate, and providing a purge gas into the chamber before or after the treating process to pump out a residue gas relative to the treating process from the chamber. The treating process includes distributing a reactant gas into the chamber through a gas distribution plate.
