摘要： Implementations of the present disclosure relate to an improved shield for use in a processing chamber. In one implementation, the shield includes a hollow body having a cylindrical shape that is substantially symmetric about a central axis of the body, and a coating layer formed on an inner surface of the body. The coating layer is formed the same material as a sputtering target used in the processing chamber. The shield advantageously reduces particle contamination in films deposited using RF-PVD by reducing arcing between the shield and the sputtering target. Arcing is reduced by the presence of a coating layer on the interior surfaces of the shield.
