摘要： A mirror including a substrate and a reflective coating that includes a first group of layers and a second group of layers arranged between the substrate and the first group of layers. Both the first and second groups of layers include a plurality of alternating first material layers and second material layers, arranged one above another. The refractive index of the first material for radiation in the range of 5-30 nm is greater than the refractive index of the second material in that wavelength range. The first group of layers is configured to have a number of layers that is greater than 20, such that, upon irradiation with radiation having a wavelength in the range of 5-30 nm, less than 20% of the radiation reaches the second group of layers, which has a layer thickness variation for correcting the surface form of the mirror.

摘要： A method of operating an illumination system of a microlithographic projection exposure apparatus is provided. A set of illumination parameters that describe properties of a light bundle which converges at a point on a mask to be illuminated by the illumination system is first determined. Optical elements whose optical effect on the illumination parameters can be modified as a function of control commands are furthermore determined, as well as sensitivities with which the illumination parameters react to an adjustment of the optical elements, induced by the control commands. The control commands are then determined while taking the previously determined sensitivities into account, such that deviations of the illumination parameters from predetermined target illumination parameters satisfy a predetermined minimisation criterion. These control commands are applied to the optical elements, before the mask is illuminated.

摘要： An illumination system of a microlithographic projection exposure apparatus can include at least one transmission filter which has a different transmittance at least at two positions and which is arranged between a pupil plane and a field plane). The transmittance distribution can be determined such that it has field dependent correcting effects on the ellipticity. In some embodiments the telecentricity and/or the irradiance uniformity is not affected by this correction.

摘要： The disclosure relates to a projection exposure apparatus for EUV microlithography which includes an illumination system for illuminating a pattern, and a projection objective for imaging the pattern onto a light-sensitive substrate. The projection objective has a pupil plane with an obscuration. The illumination system generates light with an angular distribution having an illumination pole which extends over a range of polar angles and a range of azimuth angles and within which the light intensity is greater than an illumination pole minimum value. From the illumination pole toward large polar angles a dark zone is excluded within which the light intensity is less than the illumination pole minimum value, and which has in regions a form corresponding to the form of the obscuration of the pupil plane.
