Abstract:
In a lithographic projection apparatus, a liquid supply system maintains liquid in a space between a projection system of the lithographic projection apparatus and a substrate. A sensor positioned on a substrate table, which holds the substrate, is configured to be exposed to radiation when immersed in liquid (e.g., under the same conditions as the substrate will be exposed to radiation). By having a surface of an absorption element of the sensor, that is to be in contact with liquid, formed of no more than one metal type, long life of the sensor may be obtained.

Claim (Index 21):
A movable table system for a lithographic apparatus, the lithographic apparatus comprising a projection system configured to project a beam of radiation onto a substrate and a liquid supply system configured to provide a liquid to a space between the projection system and an object facing the projection system, the movable table system comprising a movable table having:\n an essentially opaque material comprising an aperture through which electromagnetic radiation passes to a receiving surface located below the aperture and above which the liquid from the liquid supply system is to be provided, wherein the electromagnetic magnetic radiation passes to a sensor system component configured to be exposed to radiation; and a liquid impermeable material spanning at least the aperture and through which the electromagnetic radiation passes to the receiving surface below the liquid impermeable material, the liquid impermeable material having essentially planar upper and lower surfaces and the liquid impermeable material preventing liquid contacting the upper surface from passing through the aperture to contact the receiving surface.
