Abstract: Processes for producing semiconductor components and/or other finely structured components include providing a projection objective having a mirror that is located within a predetermined proximity to a pupil surface of a projection objective. In one variant, an image of a pattern is projected onto a light-sensitive substrate in multiple exposures, in which a first pupil filter function is set on the mirror during a first exposure and, during a subsequent, second exposure, a different, second pupil filter function is set by local changes of geometric reflective properties of the mirror in a locally resolving manner.

Abstract: A catadioptric lens with optical elements, which are arranged along an optical axis and with at least one concave mirror located in the vicinity of a pupillar surface of the projection lens. The concave mirror is sub-divided into a number of annular or honeycomb mirror segments, which can be displaced independently in relation to one another with the aid of piezoelectric drive elements. The mirror can be used as a phase-shifting pupillar filter, whereby the filtration function can be adjusted by the relative displacement of the mirror elements in relation to one another.

Abstract: A projection exposure system, in particular for microlithography, serves for the generation of an image in an image plane of an object arranged in an object plane. The system comprises a light source that emits a projection light bundle. The system also comprises a projection optics arranged in the optical path between the object plane and the image plane as well as at least one optical correction component arranged in the projection light optical path in front of the image plane. In order to change the optical image properties this component is coupled to at least one correction manipulator so that an optical surface of the optical correction component illuminated by the projection light bundle is moved at least regionally. In this connection the correction manipulator operates together with a correction sensor device. The correction sensor device comprises a light source that emits at least one measuring light bundle.
