    摘要: An optical system has at least two optical elements whose spatial relation with respect to each other can be changed. At least one of the optical elements comprises a plurality of optical components. The optical system comprises first measuring means for individually measuring an image defect of each optical component, and first computing means for computing first target positions for the plurality of optical components such that an overall image defect of the at least one of the optical elements is below a predetermined threshold value. Second measuring means are provided for measuring an overall image defect of the optical system, and second computing means represent the measured overall image defect as a linear combination of base functions of an orthogonal function set. The second computing means calculate second target position for the at least two optical elements so as to reduce the overall image defect.

    摘要: A method of optimizing an imaging performance of a projection exposure system is provided, wherein the projection exposure system includes an illumination optical system for illuminating a patterning structure and a projection optical system for imaging a region of the illuminated patterning structure onto a corresponding field. The method involves setting the field to a first exposure field, setting optical parameters of the projection exposure system to a first setting such that the imaging performance within the first exposure field is a first optimum performance, changing the field to a second exposure field, and changing the optical parameters to a second setting such that the imaging performance within the second exposure field is a second optimum performance.
