  • Publication number: 20230383397
    Abstract: Some implementations described herein provide a shutter disc for use during a conditioning process within a processing chamber of a deposition tool. The shutter disc described herein includes a material having a wave-shaped section to reduce heat transfer to the shutter disc and to provide relief from thermal stresses. Furthermore, the shutter disc includes a deposition of a thin-film material on a backside of the shutter disc, where a diameter of the shutter disc causes a spacing between an inner edge of the thin-film material and an outer edge of a substrate support component. The spacing prevents an accumulation of material between the thin film material and the substrate support component, reduces tilting of the shutter disc due to a placement error, and reduces heat transfer to the shutter disc.

  • Patent number: 8889435
    Abstract: A first embodiment is a method for semiconductor processing. The method comprises forming a component on a wafer in a chamber; determining a non-uniformity of the plasma in the chamber, the determining being based at least in part on the component on the wafer; and providing a material on a surface of the chamber corresponding to the non-uniformity. The forming the component includes using a plasma. The material can have various shapes, compositions, thicknesses, and/or placements on the surface of the chamber. Other embodiments include a chamber having a material on a surface to control a plasma uniformity.
