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.
