    摘要: In a lithographic projection apparatus a liquid supply system maintains liquid in a space between a final element of the projection system and the substrate of the lithographic projection apparatus. A sensor positioned on a substrate table which holds the substrate is adapted for being imaged when immersed in immersion liquid (i.e. under the same conditions as the substrate will be imaged). By ensuring that a primary outer surface of an absorption element of the sensor is formed of one or fewer metal types, long life of the sensor can be expected.
