    摘要: An illumination system for scannertype microlithography along a scanning direction with a light source emitting a wavelength especially ≦193 nm. The illumination system includes a plurality of raster elements. The plurality of raster elements is imaged into an image plane of the illumination system to produce a plurality of images being partially superimposed on a field in the image plane. The field defines a non-rectangular intensity profile in the scanning direction.
