ABSTRACT:
The present invention provides a method for processing a photolithographic substrate, comprising the placement of the photolithographic substrate on a support member in a chamber wherein the photolithographic substrate has an initial temperature of about zero degrees Celsius to about fifty degrees Celsius. A heat transfer fluid is introduced into the chamber to cool the photolithographic substrate to a target temperature of less than about zero degrees Celsius to less than about minus forty degrees Celsius. The cooled photolithographic substrate is subjected to a plasma process before the temperature of the cooled photolithographic substrate reaches the initial temperature.
