    摘要: A polarization-modulating optical element consisting of an optically active crystal material has a thickness profile where the thickness, as measured in the direction of the optical axis, varies over the area of the optical element. The polarization-modulating optical element has the effect that the plane of oscillation of a first linearly polarized light ray and the plane of oscillation of a second line early polarized light ray are rotated, respectively, by a first angle of rotation and a second angle of rotation, with the first angle of rotation and the second angle of rotation being different from each other.

    摘要: An illumination optics illuminates an object field of a projection exposure apparatus for microlithography. The illumination optics include a condenser group of optical components which guide a bundle of useful light. An objective group of bundle-guiding components is arranged downstream of the condenser group. At least one component of the condenser group and at least one component of the objective group are displaceable for compensation of deviations of the object field, which is in an actual illumination state, from a desired illumination state.

    摘要: An illumination optical unit for projection lithography for illuminating an object field, in which an object to be imaged can be arranged, with illumination light has a field facet mirror having a plurality of field facets. A pupil facet mirror of the illumination optical unit has a plurality of pupil facets. The pupil facets serve for imaging the field facets respectively assigned individually to the pupil facets into the object field. An individual mirror array of the illumination optical unit has individual mirrors that can be tilted in driven fashion individually. The individual mirror array is arranged in an illumination light beam path upstream of the field facet mirror. This can result in flexibly configurable illumination by the illumination optical unit, this illumination being readily adaptable to predetermined values.

    摘要: An illumination system for a microlithographic projection exposure step-and-scan apparatus has a light source, a first optical raster element and a second optical raster element. The first optical raster element extends in a first pupil plane of the illumination system and is designed such that the geometrical optical flux of the system is increased perpendicular to a scan direction of the projection exposure apparatus. The second optical raster element extends in a second pupil plane of the illumination system, which is not necessarily different from the first pupil plane, and is designed such that the geometrical optical flux of the system is increased in the scan direction and perpendicular thereto. This makes it possible to improve the irradiance uniformity in a reticle plane.

    摘要: A projection exposure system and a method for operating a projection exposure system for microlithography with an illumination system are disclosed. The illumination system includes at least one variably adjustable pupil-defining element. The illumination stress of at least one optical element of the projection exposure system is determined automatically in the case of an adjustment of the at least one variably adjustable pupil-defining element. From the automatically determined illumination stress, the maximum radiant power of the light source is set or determined and/or in which an illumination system is provided with which different illumination settings can be made. Usage of the projection exposure system is recorded and, from the history of the usage, at least one state parameter of at least one optical element of the projection exposure system is determined.
