    摘要: Various types of pressure regulating devices are disclosed to reduce a pressure gradient in a liquid supply system of a lithographic apparatus, the liquid supply system having a liquid confinement structure configured to at least partially confine a liquid between a projection system and a substrate table of the lithographic apparatus. A high pressure gradient may cause particulate contamination in the liquid supply system and/or liquid confinement structure. A pressure gradient can be reduced by, for example, the use of slow switching in one or more valves, a bleed flow around or through one or more valves, diversion of liquid to a drain rather than or in addition to switching a valve off, a pressure regulator or flow restrictor to prevent shock waves, and a buffer volume/damper to compensate for pressure fluctuation.

    摘要: A lithographic apparatus comprises a substrate table that supports a substrate and a substrate handler that moves the substrate relative to the substrate table. The substrate handler is adapted to load substrates on to and unload substrates from the substrate table before and after exposure. Also, a clean gas supply system supplies a clean gas to at least one location at which the substrate is located. The clean gas supply system is moveably mounted. A device manufacturing method utilizing the lithographic apparatus can be used to manufacture at least one of a flat panel display and an integrated circuit device.
