A processing apparatus for a thermal treatment of a workpiece is presented. The processing apparatus includes a processing chamber, a workpiece support disposed within the processing chamber, a gas delivery system, and radiative heat sources for heating the workpiece. The gas delivery system includes a gas showerhead assembly that is transparent to electromagnetic radiation emitted from the one or more radiative heat sources. The gas showerhead assembly includes one or more gas diffusion mechanisms to distribute gas within the enclosure.

Workpiece processing apparatus with gas showerhead assembly

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.

Rapid thermal processing system with cooling system

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.

Workpiece support for a thermal processing system

A processing apparatus for processing a workpiece is presented. The processing apparatus includes a processing chamber, a plasma chamber separated from the processing chamber disposed on a first side of the processing chamber, and a plasma source configured to generate a plasma in the plasma chamber. One or more radiative heat sources configured to heat the workpiece disposed on a second and opposite side of the first side of the processing chamber. A dielectric window is disposed between the workpiece support and the one or more heat sources. The processing apparatus includes a rotation system configured to rotate the workpiece, the rotation system comprising a magnetic actuator.

Workpiece processing apparatus with plasma and thermal processing systems

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.
