  • Publication number: 20240038504
    Abstract: A first edge ring for a substrate support is provided. The first edge ring includes an annular-shaped body and one or more lift pin receiving elements. The annular-shaped body is sized and shaped to surround an upper portion of the substrate support. The annular-shaped body defines an upper surface, a lower surface, a radially inner surface, and a radially outer surface. The one or more lift pin receiving elements are disposed along the lower surface of the annular-shaped body and sized and shaped to receive and provide kinematic coupling with top ends respectively of three or more lift pins.

  • Patent number: 10658222
    Abstract: A substrate processing system includes a processing chamber and a pedestal arranged in the processing chamber. An edge coupling ring is arranged adjacent to a radially outer edge of the pedestal. A first actuator is configured to selectively move the edge coupling ring to a raised position, relative to the pedestal to provide clearance between the edge coupling ring and the pedestal to allow a robot arm to remove the edge coupling ring from the processing chamber.

  • Patent number: 8525139
    Abstract: A wafer is provided into an entrance load lock chamber. A vacuum is created in the entrance load lock chamber. The wafer is transported to a processing tool. The wafer is processed in a process chamber to provide a processed wafer, wherein the processing forms halogen residue. A degas step is provided in the process chamber after processing the wafer. The processed wafer is transferred into a degas chamber. The processed wafer is treated in the degas chamber with UV light and a flow of gas comprising at least one of ozone, oxygen, or H2O. The flow of gas is stopped. The UV light is stopped. The processed wafer is removed from the degas chamber.

  • Patent number: 8216388
    Abstract: A method of extending storage time prior to cleaning a component of a plasma chamber is provided. The method comprises removing the component from the chamber, covering a thermal spray coating on the component while the surface is exposed to atmospheric air, storing the component, optionally removing the covering, and optionally wet cleaning reaction by-products from the thermal spray coating. Alternatively, instead of, or in addition to covering a thermal spray coating on the component, the component can be placed into a desiccator or dry-box.

  • Patent number: 7638004
    Abstract: A method of cleaning a microwave plasma applicator tube as described herein includes preparing a microwave plasma applicator for cleaning. A general cleaning of the plasma applicator tube is performed using an organic solvent wash and an ultrapure water wash. Selective cleanings of the tube are performed to remove selected contaminants. Such cleanings include a third wash with an alkaline cleaning solution, a fourth wash with an acidic cleaning solution and another wash using an ammonia and peroxide solution. The tube is rinsed using a sonicating wash performed in ultrapure water followed by drying. Also, the coil can be cleaned using acidic wash solution.
