    Abstract: An illumination system (12) for a microlithographic pro­jection exposure apparatus (10) comprises a masking de­vice (36) and a masking objective (38; 138; 238) which projects the masking device (36) onto an image plane (18). The illumination system further includes an optical correction element (46; 34'; 146a, 146b; 242; 242a, 242b, 242c) having a surface (48; 44; 44'; 148a, 148b) that is either aspherically shaped or supports diffractive struc­tures that have at least substantially the effect of an aspherical surface. This surface is arranged at least ap­proximately in a field plane (40; 140) which precedes the image plane (18) of the masking objective The aspheri­cally acting surface is designed such that a principal ray distribution generated by the illumination system (12; 112; 212) in the image plane matches a principal ray distribution required by a projection objective (16).

    Abstract: An illumination system for a microlithography projection exposure installation is used to illuminate an illumination field with the light from a primary light source (11). The illumination system has a light distribution device (25) which receives light from the primary light source and, from this light, produces a two-dimensional intensity distribution which can be set variably in a pupil-shaping surface (31) of the illumination system. The light distribution device has at least one optical modulation device (20) having a two-dimensional array of individual elements (21) that can be controlled individually in order to change the angular distribution of the light incident on the optical modulation device. The device permits the variable setting of extremely different illuminating modes without replacing optical components.

    Abstract: An illumination system of a microlithographic exposure apparatus (PEA) has an optical axis (OA) and a beam transforming device (20; 120; 220; 320; 420; 520; 1020; 1120; 1220; 1320; 1420; 1520). This device comprises a first mirror (122; 222; 322; 422; 522; 1122; 1222; 1322; 1422; 1522) with a first reflective surface (124; 224; 424; 524; 1124; 1224) having a shape that is defined by rotating a straight line, which is inclined with respect to the optical axis (OA), around the optical axis (OA). The device further comprises a second mirror (126, 126a, 126b; 226a, 226b; 326a, 326b; 426a; 426b; 526; 1126; 1226; 1326a, 1326b; 1426a, 1426b; 1526a, 1526b) with a second reflective surface (130, 130a, 130b; 1130) having a shape that is defined by rotating a curved line around the optical axis (OA). At least one of the mirrors has a central aperture (128) containing the optical axis (OA). This device may form a zoom-collimator (1020; 1120; 1220; 1320; 1420; 1520) for an EUV illumination system that transforms a diverging light bundle into a collimated light bundle of variable shape and/or diameter.

    Abstract: An illumination system for a microlithographic projection exposure apparatus comprises a light source (14), a first optical unit (26; 26’) having an exit pupil (32), an optical raster element (34) positioned in or in close proximity to the exit pupil (32) of the first optical unit (26; 26’) and a field plane (26) that is conjugated to the exit pupil (32) of the first optical unit (26; 26’) by Fourier transformation. The illumination system further comprises a second optical unit (42) imaging the field plane (36) into an image plane (44) and having at its object side a homocentric entrance pupil that at least substantially coincides with the exit pupil (32) of the first optical unit. This allows to dispense with a condenser lens that is usually required for conjugating the exit pupil (32) to the field plane (36).
