    摘要: A microlithographic illumination system can include a light distribution device that can generate a two-dimensional intensity distribution in a first illumination plane. A first raster array of optical raster elements can generates a raster array of secondary light sources. A device with an additional optical effect can be disposed spatially adjacent to the two raster arrays. The device can be configured as an illumination angle variation device. The device can influence the intensity and/or the phase and/or the beam direction of the illumination light. The influence can be such that an intensity contribution of raster elements to the total illumination intensity can vary across the illumination field. This can enable the illumination intensity to be influenced across the illumination field in a defined manner with respect to the total illumination intensity and/or with respect to the intensity contributions from different directions of illumination.

    摘要: A projection exposure apparatus for microlithography comprises illumination optics for illuminating object field points of an object field in an object plane is disclosed. The illumination optics have, for each object field point of the object field, an exit pupil associated with the object point, where sin(γ) is a greatest marginal angle value of the exit pupil. The illumination optics include a multi-mirror array that includes a plurality of mirrors to adjust an intensity distribution in exit pupils associated to the object field points. The illumination optics further contain at least one optical system to temporally stabilize the illumination of the multi-mirror array so that, for each object field point, the intensity distribution in the associated exit pupil deviates from a second adjusted intensity distribution in the associated exit pupil by less than 0.1 in at least one of an inner σ or an outer σ.

    摘要: An illumination system of a micro-lithographic projection exposure apparatus is provided, which is configured to illuminate a mask positioned in a mask plane. The system includes a pupil shaping optical subsystem and illuminator optics that illuminate a beam deflecting component. For determining a property of the beam deflecting component, an intensity distribution in a system pupil surface of the illumination system is determined. Then the property of the beam deflecting component is determined such that the intensity distribution produced by the pupil shaping subsystem in the system pupil surface approximates the intensity distribution determined before. At least one of the following aberrations are taken into account in this determination: (i) an aberration produced by the illuminator optics; (ii) an aberration produced by the pupil shaping optical subsystem; (iii) an aberration produced by an optical element arranged between the system pupil surface and the mask plane.
