A first facet mirror (6) has first facets (21) for reflecting guidance of illumination light (3) and for arrangement in a used region of a far field of an EUV light source. A second facet mirror (7) serves for reflecting guidance of the illumination light (3) reflected by the first facet mirror (6) to the object field (8). The second facet mirror (7) has second facets (25) for guiding respectively one illumination light partial beam (26) into the object field (8). The first facet mirror (6) is arranged in a field plane (6a) of the illumination optical unit. The second facet mirror (7) is arranged at a distance from a field plane (6a) and from a pupil plane (12b) of the illumination optical unit. The two facet mirrors (6, 7) are arranged in relation to one another in such a way that at least some of the illumination light partial beams (26) are guided over first facets (21) of the first facet mirror (6) with seamlessly connected reflection surfaces. An illumination optical unit without the mandatory use of a MEMS mirror as first facet mirror emerges.

摘要： According to a method of operating an illumination System of a microlithographic projection apparatus, a spatial light modulator (52) having a modulation surface (222) is provided which is formed by a plurality of micromirrors (56). Each micromirror comprises a mirror surface (224-1-1 to 224-4-9) having an orientation that can be changed individually for each micromirror. For at least one of the micromirrors, at least one parameter that is related to the mirror surface is measured. The orientation of the mirror surfaces is controlled depending on the at least one measured parameter. A light pattern is produced on the modulation surface (222), and an image of the light pattern is formed on an optical Integrator (60) that has a plurality of light entrance facets (75). Finally, images of the light entrance facets (75) are superimposed on a mask (16).

摘要： An illumination optical unit (32) for projection lithography serves for illuminating an object field (5), in which an object to be imaged can be arranged, with illumination light (14). The illumination optical unit has a collector for collecting the emission of a light source for the illumination light (14). The collector is arranged such that it transfers the illumination light (14) from the light source into an intermediate focus (16). The illumination optical unit (32) furthermore has a field facet mirror (20) and a pupil facet mirror (21), each having a plurality of facets (22, 23). The field facets (22) are imaged into the object field (5) by a transfer optical unit (21). The illumination optical unit (32) additionally has an individual-mirror array (17) having individual mirrors tiltable in a manner driven individually, said array being arranged upstream of the field facet mirror (20) and downstream of the intermediate focus (16) in an illumination beam path (26). The intermediate focus (16) is imaged via illumination channels (24), which are each formed by at least one of the individual mirrors and at least one of the field facets (22) and which guide a partial beam of the illumination light (14), into a spatial region (25) in which the pupil facet mirror (21) is situated. This results in illumination of the object to be imaged which can be designed in a flexible fashion and is readily adaptable to predetermined values.

摘要： An EUV light source (2) serves for generating a usable output beam (3) of EUV illumination light for a projection exposure apparatus (1) for projection lithography. The light source (2) has an EUV generation device (2c) which generates an EUV raw output beam. The latter is circularly polarized. For the purposes of setting the polarization of the usable output beam (3) and in respect of the polarization direction, a polarization setting device (32; 39) has a linearly polarizing effect on the raw output beam. This results in an EUV light source, which provides an improved output beam for a resolution-optimized illumination.
