    摘要: A pedestal assembly for a processing region and comprising first pins coupled to a substrate support, configured to mate with first terminals of an electrostatic chuck, and are configured to be coupled to a first power source. Each of the first pins comprises an interface element, and a compliance element supporting the interface element. Second pins are coupled to the substrate support, configured to mate with second terminals of the electrostatic chuck, and configured to couple to a second power source. Alignment elements are coupled to the substrate support and are configured to interface with centering elements of the electrostatic chuck. The flexible element is coupled to the substrate support, configured to interface with a passageway of the electrostatic chuck, and configured to be coupled to a gas source.

    摘要: Embodiments of the present disclosure generally relate to lift pins and to apparatus for controlling lift pin movement. In an embodiment, an apparatus for positioning a substrate in a chamber is provided. The apparatus includes a chamber component, a lift pin having a top surface for supporting the substrate and a lift pin shaft and a stopper. The apparatus further includes a compressible element positioned between the chamber component and the stopper, the compressible element further positioned around the lift pin shaft, the lift pin being moveable relative to a substrate transfer plane by movement of a substrate support in contact with the compressible element.
