    Abstract: An illumination system (12) of a microlithographic expo­sure system comprises a plurality of light emitting ele­ments (24) that have light exit facets that are-posi­tioned in or in close proximity to à field plane (OP) or a pupil plane and are configured to be individually acti­vated. Light collecting elements, for example microlenses of a fly-eye lens or arrays of cylinder lenses, may be used to collect the light bundles emitted by the light' emitting elements (24). Homogenizing means, for example a rod integrator or an optical raster element (40), may be provided for improving the intensity uniformity in a re­ticle plane (RP).

    Abstract: An illumination system for a microlithographic projection exposure step-and-scan apparatus has a light source (14), a first optical raster element (62; 62'; 62''; 62''') and a second optical raster element (64; 90; 90''; 100). The first optical raster element extends in a first pupil plane (28) of the illumination system (10) 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 (28) of the illumination system, which is not necessarily different from the first pupil plane (28), and is designed such that the geometrical optical flux of the system is increased in the scan direction and perpendicular thereto. This allows to improve the irradiance uniformity in a reticle plane (46).

    Abstract: A projection exposure apparatus for microlithography comprises illumination optics for illuminating object field points of an object field in an object plane. The illumination optics have, for each object field point of the object field, an exit pupil associated with the object point, wherein sin(γ) is a greatest marginal angle value of the exit pupil, and wherein the illumination optics comprise a multi-mirror array (38) comprising a plurality of mirrors (38s) for adjusting an intensity distribution in exit pupils associated to the object field points. The illumination optics further contain at least one optical system (33a; 33b,; 33c; 3d; 400; 822; 903; 1010; 1103; 1203) for temporally stabilising the illumination of the multi-mirror array (38) so that, for each object field point, the intensity distribution in the associated exit pupil deviates from a desired intensity distribution in the associated exit pupil in the case of a centroid angle value sin(β) by less than 2% expressed in terms of the greatest marginal angle value sin(γ) of the associated exit pupil and/or, in the case of ellipticity by less than 2%, and/or in the case of a pole balance by less than 2%.
