    摘要: Methods and apparatus for maintaining the thermal equilibrium of a substrate and an immersion lithographic apparatus are disclosed using or having a timetable comprising information regarding the position, speed and/or acceleration of the substrate; and an evaporation controller and/or condensation controller acting to decrease localized evaporation and/or increase localized condensation in response to the information in the timetable. Evaporation of liquid from the surface of the substrate cools it down, while condensing liquid on its bottom surface heats the substrate locally.

    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.
