摘要： An objective for a microlithography projection system has at least one fluoride crystal lens. The effects of birefringence, which are detrimental to the image quality, are reduced if the lens axis of the crystal lens is oriented substantially perpendicular to the {100}-planes or {100}-equivalent crystallographic planes of the fluoride crystal. If two or more fluoride crystal lenses are used, they should have lens axes oriented in the (100)-, (111)-, or (110)-direction of the crystallographic structure, and they should be oriented at rotated positions relative to each other. The birefringence-related effects are further reduced by using groups of mutually rotated (100)-lenses in combination with groups of mutually rotated (111)- or (110)-lenses. A further improvement is also achieved by applying a compensation coating to at least one optical element of the objective.

摘要： A method for operating a projection exposure tool for microlithography is provided. The projection exposure tool includes an optical system which includes a number of optical elements which, during an imaging process, convey electromagnetic radiation. All of the surfaces of the optical elements interact with the electromagnetic radiation during the imaging process to form an overall optical surface of the optical system. The method includes: determining respective individual thermal expansion coefficients at at least two different locations of the overall optical surface; calculating a change to an optical property of the optical system brought about by heat emission of the electromagnetic radiation (during the imaging process upon the basis of the thermal expansion coefficients; and imaging mask structures into an image plane via the projection exposure tool with adaptation of the imaging characteristics of the projection exposure tool so that the calculated change to the optical property is at least partially compensated.

摘要： An illumination system for microlithography serves to illuminate an illumination field with illumination light of a primary light source. A first raster arrangement has bundle-forming first raster elements which are arranged in a first plane of the illumination system or adjacent to the plane. The first raster arrangement serves to generate a raster arrangement of secondary light sources. A transmission optics serves for superimposed transmission of the illumination light of the secondary light sources into the illumination field. The transmission optics has a second raster arrangement with bundle-forming second raster elements. In each case one of the raster elements of the first raster arrangement is allocated to one of the raster elements of the second raster arrangement for guiding a partial bundle of an entire bundle of illumination light. The first raster arrangement for example has at least two types (I, II, III) of the first raster elements which have different bundle-influencing effects. The raster elements of the two raster arrangements are arranged relative to one another in such a way that to each raster element type (I to III) is allocated at least one individual distance (ΔI, ΔII, ΔIII) between the first raster element of this type (I to III) and the allocated second raster element of the second raster arrangement. As a result, an illumination system is obtained which allows particular illumination parameters to be influenced in such a way that undesirable influences on other illumination parameters are avoided to the greatest extent possible.
