    Abstract: A system for controlling temperature of a patterning device in a lithographic apparatus is discussed. The system includes a cooling system and a heating system. The cooling system is configured to direct a gas flow along a first direction across a surface of the patterning device to remove heat from the patterning device prior to exposing the patterning device or during exposure of the patterning device. The heating system is configured to selectively heat areas on the surface of the patterning device prior to exposing the patterning device or during exposure of the patterning device. The selective heating and the heat removal achieve a substantially uniform temperature distribution in the patterning.

    Abstract: In one embodiment of the present invention, there is provided a gas gauge for use in a vacuum environment having a measurement gas flow channel. The gas gauge may comprise a measurement nozzle in the measurement gas flow channel. The measurement nozzle may be configured to operate at a sonically choked flow condition of a volumetric flow being sourced from a gas supply coupled to the measurement gas flow channel. The gas gauge may further comprise a pressure sensor operatively coupled to the measurement gas flow channel downstream from the sonically choked flow condition of the volumetric flow to measure a differential pressure of the volumetric flow for providing an indication of a gap between a distal end of the measurement nozzle and a target surface proximal thereto.
