Abstract
Embodiments of the disclosure provide methods for fabricating or otherwise forming a protective coating containing cerium oxide on processing chamber surfaces and/or components, such as surfaces which are exposed to a plasma within a processing chamber. In one or more embodiments, a method of forming a protective coating within a processing chamber includes depositing a cerium oxide layer on a chamber surface or a chamber component during an atomic layer deposition (ALD) process. The ALD process includes sequentially exposing the chamber surface or the chamber component to a cerium precursor, a purge gas, an oxidizing agent, and the purge gas during an ALD cycle, and repeating the ALD cycle to deposit the cerium oxide layer.
