Patent number: 11622419Abstract: 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.Type: GrantFiled: October 8, 2019Date of Patent: April 4, 2023Assignee: Applied Materials, Inc.Inventors: Chunlei Zhang, Phillip Criminale, Steven E.

Patent number: 11393710Abstract: 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.
