Abstract

A patterning device support (1100) for controlling a temperature of a patterning device (1102) can include a movable component (1104). The movable component can include a gas inlet (1108) for supplying a gas flow across a surface of the patterning device and a gas outlet (1110) for extracting the gas flow. The patterning device support can also include a gas flow generator (1118) coupled to a duct (1114, 1116) for recirculating the gas flow from the gas outlet to the gas inlet.
