摘要:
A plasma source having a plasma chamber with metal chamber walls contains a process gas. A dielectric window passes a RF signal into the plasma chamber. The RF signal excites and ionizes the process gas, thereby forming a plasma in the plasma chamber. A plasma chamber liner that is positioned inside the plasma chamber provides line-of-site shielding of the inside of the plasma chamber from metal sputtered by ions striking the metal walls of the plasma chamber.
