  • Patent number: 8117878
    Abstract: A textured process shield and similar parts may be formed and textured in the same forming process using a mandrel. The mandrel may have movable portions that may be set into a forming die position to form and texture a workpiece into a process shield and collapsed to allow the process shield to be removed from the mandrel. The movable portions may include several textured shoes supported by movable jaws. The movable portions may also include a contact surface having angled indentations.

  • Patent number: 6933508
    Abstract: A method and system for providing a texture to a surface of a workpiece is provided. The method comprises providing a workpiece to a texturizing chamber and scanning a beam of electromagnetic energy across the surface of the workpiece to form a plurality of features thereon. The features formed are generally depressions, protuberances, and combinations thereof. Also provided is a method of reducing contamination in a process chamber. The method comprises scanning a beam of electromagnetic energy across a surface of one or more process chamber components to form a plurality of features thereon, positioning the one or more chamber components into a process chamber, and initiating a process sequence within the process chamber.

  • Patent number: 6812471
    Abstract: A method and system for providing a texture to a surface of a workpiece, such as a chamber component is provided. The method comprises providing a workpiece to a texturizing chamber and scanning a beam of electromagnetic energy across the surface of the workpiece to form a plurality of features thereon. The features formed are generally depressions, protuberances, and combinations thereof. The chamber components may include, for example, a chamber shield and related assembly, a target, a shadow ring, a contact ring, a substrate support or other component disposable within a processing chamber. Also provided is a method of reducing contamination in a process chamber. The method comprises scanning a beam of electromagnetic energy across a surface of one or more process chamber components to form a plurality of features thereon, positioning the one or more chamber components into a process chamber, and initiating a process sequence within the process chamber.
