摘要: A patterning apparatus for a lithographic apparatus, the patterning apparatus including a patterning device support structure configured to support a patterning device having a planar surface; a patterning device conditioning system including a first gas outlet configured to provide a first gas flow over the planar surface in use and a second gas outlet configured to provide a second gas flow over the planar surface in use, wherein the first gas outlet and the second gas outlet are arranged at different distances perpendicular to the planar surface; and a control system configured to independently control a first momentum of gas exiting the first gas outlet and a second momentum of gas exiting the second gas outlet or to independently vary the first gas flow and/or the second gas flow over the planar surface of the patterning device.

摘要: An apparatus, system, and method cool a patterning device by supplying a non-uniform gas flow. The apparatus and system include a gas supply structure that supplies a gas flow across the first surface of the patterning device. The gas supply structure includes a gas supply nozzle specially configured to create a non-uniform gas flow distribution. A greater volume or velocity of the gas flow is directed to desired portion of the patterning device.

摘要: 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.
