    摘要： There is provided an illumination system. The illumination system includes a source for light having a wavelength ≦193 nm, a field plane, and a collector having a mirror shell for receiving a part of the light. The mirror shell is arranged so that a real image of the source is formed and comes to lie in a plane that is defocused relative to the field plane by more than 30 mm, so that the field plane is illuminated in a predetermined region, substantially homogeneously.

    摘要： 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.

    摘要： There is provided an illumination system for microlithography with wavelengths ≦193 nm. The illumination system includes a primary light source, a first optical component, a second optical component, an image plane, and an exit pupil. The first optical component transforms the primary light source into a plurality of secondary light sources that are imaged by the second optical component in the exit pupil. The first optical component includes a first optical element having a plurality of first raster elements that are imaged into the image plane, producing a plurality of images being superimposed at least partially on a field in the image plane. The plurality of first raster elements are rectangular. The field is a segment of an annulus, and the second optical component includes a first field mirror with negative optical power for shaping the field to the segment of the annulus and a second field mirror with positive optical power. Each of a plurality of rays intersects the first field mirror with an incidence angle greater than 70° and each of the plurality of rays intersects the second field mirror with an incidence angle of less than 25°.

    摘要： An illumination system comprises (a) a first optical element upon which a light beam impinges, where the first optical element has first raster elements that partition said light beam into light channels; (b) a second optical element that receives said light channels, where the second optical element has a second raster elements; (c) an object plane that receives said light channels via said second optical element; and (d) an exit pupil that is provided with an illumination via said object plane. The system is characterized by an assignment of a member of said first raster elements and a member of said second raster elements to each of said light channels to provide a continuous beam path from said first optical element to said object plane for each of said plurality of light channels. The assignment is changeable to provide an adjustment of said illumination in said exit pupil.
