  • Patent number: 11622419
    Abstract: Implementations described herein provide a method for processing a substrate on a substrate support assembly which enables both lateral and azimuthal tuning of the heat transfer between an electrostatic chuck and a substrate. The method includes processing a first substrate using a first temperature profile on a substrate support assembly having primary heaters and spatially tunable heaters. A deviation profile is determined from a result of processing the first substrate. The spatially tunable heaters are controlled in response to the deviation profile to enable discrete lateral and azimuthal tuning of local hot or cold spots on the substrate support assembly in forming a second temperature profile. A second substrate is then processed using the second temperature profile.

  • Publication number: 20220319904
    Abstract: Apparatuses including a height-adjustable edge ring, and methods for use thereof are described herein. In one example, a process kit for processing a substrate is provided. The process kit has a support ring comprising an upper surface having an inner edge disposed at a first height and an outward edge disposed at a second height less than the first height, the inner edge having a greater thickness than the outward edge. An edge ring is disposed on the support ring, an inner surface of the edge ring interfaced with the inner edge of the support ring. A cover ring is disposed outward of the edge ring, the edge ring independently moveable relative to the support ring and the cover ring. Push pins are disposed inward of the cover ring, the push pins operable to elevate the edge ring while constraining radial movement of the support ring.

  • Patent number: 11393710
    Abstract: Apparatuses including a height-adjustable edge ring, and methods for use thereof are described herein. In one example, a substrate support assembly includes a height-adjustable edge ring, and the substrate support assembly is located within a process chamber. The substrate support assembly includes an electrostatic chuck, an edge ring positioned on a portion of the electrostatic chuck, and one or more actuators to adjust the height of the edge ring via one or more push pins. The height-adjustable edge ring can be used to compensate for erosion of the edge ring over time. In addition, the height-adjustable edge ring can be removed from the process chamber via a slit valve opening without venting and opening the process chamber. The height-adjustable edge ring can be tilted by the one or more actuators in order to improve azimuthal uniformity at the edge of the substrate.
