  • Publication number: 20220205478
    Abstract: A workpiece support for a thermal processing system is provided. The workpiece support includes a rotor configured to support a workpiece. The workpiece support further includes a gas supply. The gas supply can include a plurality of bearing pads. Each of the bearing pads can be positioned closer to a periphery of the rotor than a center of the rotor. Each of the bearing define one or more passages configured to direct gas onto the rotor to control a position of the rotor along a first axis and a second axis that is substantially perpendicular to the first axis. Furthermore, one or more of the bearing pads define at least one additional passage configured to direct gas onto the rotor to control rotation of the rotor about the first axis.

  • Publication number: 20220059363
    Abstract: Apparatus, systems, and methods for processing workpieces are provided. In one example, such a method for performing a spike anneal rapid thermal process may include controlling a heat source to begin heating a workpiece supported on a workpiece support in a processing chamber. The method may further include receiving data indicative of a temperature of the workpiece. Furthermore, the method may include monitoring the temperature of the workpiece relative to a temperature setpoint. Moreover, the method may include controlling the heat source to stop heating the workpiece based at least in part on the workpiece reaching the temperature setpoint. Additionally, the method may include controlling a cooling system to begin flowing a cooling gas at a rate of about 300 slm or greater over the workpiece based at least in part on the workpiece reaching the temperature setpoint to reduce a t50 peak width of the workpiece.

  • Publication number: 20210272839
    Abstract: Support plates and support structures for thermal processing systems to heat workpieces are provided. In one example, a thermal processing apparatus is provided that includes a plurality of heat sources, a rotatable support plate, and a support structure having a flexibility in the radial direction of the rotatable support plate that is greater than a flexibility in the azimuthal direction of the rotatable support plate. Also provided are support plates for supporting a workpiece in a thermal processing apparatus. The support plate can include a base defining a radial direction and an azimuthal direction and at least one support structure extending from the base having a flexibility in the radial direction of the base that is greater than a flexibility in the azimuthal direction of the base.
