  • Patent number: 9001489
    Abstract: The present invention generally relates to a refurbished electrostatic chuck and a method of refurbishing a used electrostatic chuck. Initially, a predetermined amount of dielectric material is removed from the used electrostatic chuck to leave a base surface. Then, the base surface is roughened to enhance the adherence of new dielectric material thereto. The new dielectric material is then sprayed onto the roughened surface. A mask is then placed over the new dielectric material to aid in the formation of mesas upon which a substrate will sit during processing. A portion of the new dielectric layer is then removed to form new mesas. After removing the mask, edges of the mesas may be smoothed and the refurbished electrostatic chuck is ready to return to service after cleaning.

  • Publication number: 20120258280
    Abstract: A processing chamber component and method for fabricating the same are provided. The processing chamber component is fabricated in the manner described herein and includes the creation of at least a macro texture on a surface of the chamber component. The macro texture is defined by a plurality of engineered features arranged in a predefined orientation on the surface of the chamber component. In some embodiments, the engineered features prevent formation of a line of sight surface defined between the features to enhance retention of films deposited on the chamber component.

  • Publication number: 20120255635
    Abstract: Embodiments described herein generally relate to methods and apparatus for refurbishing a gas distribution plate assembly utilized in a deposition chamber or etch chamber. In one embodiment, a method for refurbishing a gas distribution plate assembly is provided. The method includes urging a faceplate of a gas distribution plate assembly against a polishing pad of a polishing device, the faceplate having a plurality of gas distribution holes disposed therein, providing relative motion between the faceplate and the polishing pad, and polishing the faceplate against the polishing pad.
