    Abstract: PROBLEM TO BE SOLVED: To provide an EUV lithography apparatus, a cleaning configuration for efficiently removing contaminant for the apparatus, and a cleaning configuration for recovering reflectivity of an EUV optical component. SOLUTION: A collector CO is disposed, for example, in a cleaning cocoon so as for the collector CO to be disposed between two particular volumes or enclosures 12 and 14. Radicals such as H radicals are generated in one or both of the volumes 12 and 14, and a pressure region in a range of 1 to 10 Pa is used to produce a flux such that the radicals are moved in the collector CO. The H radicals are moved from the volume 12 to the volume 14, thereby they collide with a wall of the collector CO, so that they can clean a Sn contaminant or the like on the wall of the collector CO.

    Abstract: A lithographic apparatus that includes an illumination system configured to condition a radiation beam. The illumination system includes a plurality of optical components. The apparatus also includes a support constructed to support a patterning device. The patterning device is capable of imparting the radiation beam with a pattern in its cross-section to form a patterned radiation beam. The apparatus further includes a substrate table constructed to hold a substrate, and a projection system configured to project the patterned radiation beam onto a target portion of the substrate. The projection system includes a plurality of optical components. The apparatus also includes a contamination measurement unit for measuring contamination of a surface of at least one of the optical components. The contamination measurement unit is provided with a radiation sensor constructed and arranged to measure an optical characteristic of radiation received from the surface.
