  • Patent number: 8409355
    Abstract: Embodiments of process kits for substrate supports of semiconductor substrate process chambers are provided herein. In some embodiments, a process kit for a semiconductor process chamber may include an annular body being substantially horizontal and having an inner and an outer edge, and an upper and a lower surface; an inner lip disposed proximate the inner edge and extending vertically from the upper surface; and an outer lip disposed proximate the outer edge and on the lower surface, and having a shape conforming to a surface of the substrate support pedestal. In some embodiments, a process kit for a semiconductor process chamber my include an annular body having an inner and an outer edge, and having an upper and lower surface, the upper surface disposed at a downward angle of between about 5-65 degrees in an radially outward direction from the inner edge toward the outer edge.

  • Patent number: 7354288
    Abstract: A substrate support comprises a ceramic disc with an electrode that is chargeable through an electrode terminal. An electrical connector connects an external power source to the electrode terminal. The electrical connector has a pair of opposing pincer arms, a groove sized to fit around the electrode terminal, and a pair of through holes to receive a tightening assembly capable of tightening the opposing pincer arms about the electrode terminal.
