  • Publication number: 20070068629
    Abstract: An actively heated aluminum baffle component such as a thermal control plate or baffle ring of a showerhead electrode assembly of a plasma processing chamber has an exposed outer aluminum oxide layer which is formed by an electropolishing procedure. The exposed outer aluminum oxide layer minimizes defects and particles generated as a result of differential thermal stresses experienced by the aluminum component and outer aluminum oxide layer during plasma processing compared to an identically shaped component having a Type III anodized surface.
