    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.

    Abstract: A lithographic system includes an immersion type lithographic apparatus, which includes a support constructed and arranged to support a substrate, a projection system constructed and arranged to project a patterned beam of radiation onto a target portion of the substrate, a liquid confinement structure configured to at least partially fill a space between the projection system and at least one of the substrate and support with an immersion liquid, a liquid supply system arranged to provide the immersion liquid to the liquid confinement structure, and a cleaning liquid supply system arranged to provide a cleaning liquid to a surface of the lithographic apparatus that comes into contact with the immersion liquid. The system includes a switch to provide the cleaning liquid directly to the liquid confinement structure and to provide the immersion liquid indirectly to the liquid confinement structure via a liquid purification system.
