    摘要: A method for improving imaging properties of two or more optical elements comprises the step of determining for at least one of the two optical elements a polarisation-dependent perturbation. In a further step a polarisation-independent perturbation is determined for at least one of the two optical elements. Then a target position for the at least one movable optical element is calculated such that, in the target position, the total perturbation of the at least two optical elements which is made up of the polarisation-dependent perturbations and polarisation-independent perturbations of the two optical elements, is minimized. Finally the at least one movable optical element is moved the to the calculated target position.

    摘要: In a method for making an optical system for imaging a radiation distribution from an input surface of the optical system into an output surface of the optical system, the optical system has a multiplicity of optical components which determine an imaging quality of the optical system, which are arranged along an optical axis of the optical system and comprise at least one optical component which has a substrate with a substrate surface which is provided for carrying an interference layer system having a layer construction that determines the optical properties of the optical component covered with the interference layer system. The method includes: predefining an optimization target for at least one imaging quality parameter that represents the imaging quality of the system; determining the imaging quality of the optical system while taking account of the layer construction of the interference layer system; and varying the layer construction for approximating the imaging quality parameter to the optimization target. In accordance with the method, the determination of the optimum layer construction is coupled directly with an assessment and of the imaging quality of the total system including the interference layer system to be optimized.

    摘要: In a method for improving the imaging properties of a projection objective of a microlithographic projection exposure apparatus, an appropriate illumination angle distribution adapted to a mask (24; 224) to be projected is selected. Then locations (40a, 40b; 60a, 60b; 80a, 80b, 80c) in an exit pupil of the projection objective (20), which are illuminated under these conditions by projection light during a projection of the mask, are determined. For at least one image point, an actual value of an imaging quantity, e.g. a wavefront profile or a polarization state, is determined that influences the imaging properties of the projection objective. Finally, corrective measures are calculated such that the actual value of the imaging quantity approximates a desired value at these locations. In this last step, however, deviations of the actual value from the desired value are taken into account exclusively at said locations illuminated in the exit pupil.

    摘要: A catadioptric projection objective for projecting a pattern, which is located in the object plane of the projection objective, into the image plane of the projection objective has, between the object plane and the image plane, a catadioptric objective part provided with a concave mirror (17), with a first deviating mirror (16) and with at least one second deviating mirror (19). A polarization rotating device (26) rotates the preferred polarization direction of the light approximately 90° inside the light path between the deviating mirrors. This permits an at least partial compensation for polarization-dependent reflectivity differences and phase effect differences of the deviating mirrors thereby enabling a projection with a largely identical contrast for all structural directions.

    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.
