    摘要: A projection exposure tool for microlithography for exposing a substrate is disclosed. The tool includes a projection objective. The tool also includes an optical measuring apparatus for determining a surface topography of the substrate before the substrate is exposed. The measuring apparatus has a measuring beam path which extends outside of the projection objective. The measuring apparatus is a wavefront measuring apparatus configured to determine topography measurement values simultaneously at a number of points on the substrate surface.

    摘要: A projection objective for microlithography includes at least one optical assembly with optical elements which are disposed between an object plane and an image plane. The optical assembly includes at least one optical terminal element, which is disposed close to the image plane. A first immersion liquid is disposed on the image oriented surface of the optical terminal element. A second immersion liquid is disposed on the object oriented surface of the optical terminal element. The object oriented surface includes a first surface section for the imaging light to enter into the terminal element, and the image oriented surface includes a second surface portion for the imaging light to exit from the terminal element.

    摘要: The disclosure relates to a microlithographic projection exposure apparatus and a microlithographic projection exposure apparatus, as well as related components, methods and articles made by the methods. The microlithographic projection exposure apparatus includes an illumination system and a projection objective. The illumination system can illuminate a mask arranged in an object plane of the projection objective. The mask can have structures which are to be imaged. The method can include illuminating a pupil plane of the illumination system with light. The method can also include modifying, in a plane of the projection objective, the phase, amplitude and/or polarization of the light passing through that plane. The modification can be effected for at least two diffraction orders in mutually different ways. A mask-induced loss in image contrast obtained in the imaging of the structures can be reduced compared to a method without the modification.
