A method and apparatus for performing post-exposure bake cooling operations is described herein. The method begins by post exposure baking a substrate disposed on heated substrate support in a process chamber, the process chamber having a showerhead. The heated substrate support is moved to increase a distance between the heated substrate support and a cooled plate of the showerhead. The substrate is separated from the heated substrate support using a substrate lifting device. The substrate is moved into a close proximity to the cooled showerhead. The substrate is cooled until the substrate is less than about 70 degrees Celsius. The substrate is spaced away from the cooled showerhead using the substrate lifting device and aligning the substrate with a substrate transfer passage of the processing chamber for removal by a robot.
