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 31):
A device manufacturing method, comprising:\n projecting a beam of radiation onto a radiation-sensitive substrate through liquid in a space between a projection system of a lithographic apparatus and the substrate; providing a liquid between the projection system and an essentially opaque material of a movable table of the lithographic apparatus, the essentially opaque material comprising an aperture through which electromagnetic radiation can pass to a receiving surface located below the aperture and above which the liquid is provided; and passing electromagnetic radiation through a liquid impermeable material spanning at least the aperture to the receiving surface below the liquid impermeable material and toward a sensor system component configured to be exposed to radiation, 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.
