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 18):
The method of  claim 15 , further comprising:\n determining a shape of the patterning device based on the measured parameter; and calculating, based on the shape of the patterning device, at least one of a temperature profile of the patterning device and a temperature profile of the volume between the patterning device and the lens of the projection system, wherein the adjusting the set point based on the parameter comprises adjusting the set point based on the calculated at least one of a temperature profile of the patterning device and a temperature profile of the volume between the patterning device and the lens of the projection system.
