Abstract:
A lithographic apparatus ( 100 ) includes a patterning device support structure ( 104 ) configured to support a patterning device ( 110 ), a gas inlet ( 116 ) configured to provide a gas flow ( 114 ) across a surface of the patterning device, and a temperature conditioning device ( 134 ) configured to condition the temperature of the gas flow based on a set point. The apparatus also includes a sensor ( 132 ) configured to measure a parameter indicative of an amount of heat added to at least one of the patterning device and a volume ( 126 ) between the patterning device and a lens ( 124 ) of a projection system ( 106 ) during operational use of the lithographic system. Further, the apparatus includes a controller ( 130 ) operatively coupled to the sensor and configured to adjust the set point based on the parameter measured by the sensor to control a temperature of the patterning device.

Claim (Index 14):
A method for controlling a temperature of a patterning device, comprising:\n flowing gas across a surface of the patterning device; adjusting a temperature of the gas based on a set point; measuring a parameter indicative of an amount of heat added to at least one of (a) the patterning device and (b) a volume between the patterning device and a lens of a projection system during operational use of the lithographic system; and adjusting the set point based on the parameter.
