Abstract:
An apparatus and method for controlling temperature of a patterning device in a lithographic apparatus, by flowing gas across the patterning device. A patterning apparatus includes: a patterning device support structure configured to support a patterning device; a patterning device conditioning system including a first gas outlet configured to provide a gas flow over a surface of the patterning device and a second gas outlet configured to provide a gas flow over a part of a surface of the patterning device support structure not supporting the patterning device; and a control system configured to separately control the temperature of the gas exiting the first and second gas outlets such that the gas exiting the second gas outlet is at a higher temperature than the gas exiting the first gas outlet and/or to separately control the temperature and gas flow rate of the gas exiting the first and second gas outlets.

Claim (Index 17):
The patterning apparatus according to  claim 12 , wherein the control system is configured to control the gas flow rate at each gas outlet to provide substantially the same gas velocity at each of the at least one first gas outlet and the at least one second gas outlet.
