    摘要: An EUV optical projection system includes at least six reflecting surfaces for imaging an object (OB) on an image (IM). The system is preferably configured to form an intermediate image (IMI) along an optical path from the object (OB) to the image (IM) between a secondary mirror (M2) and a tertiary mirror (M3), such that a primary mirror (M1) and the secondary mirror (M2) form a first optical group (G1) and the tertiary mirror (M3), a fourth mirror (M4), a fifth mirror (M5) and a sixth mirror (M6) form a second optical group (G2). The system also preferably includes an aperture stop (APE) located along the optical path from the object (OB) to the image (IM) between the primary mirror (M1) and the secondary mirror (M2). The secondary mirror (M2) is preferably concave, and the tertiary mirror (M3) is preferably convex. Each of the six reflecting surfaces preferably receives a chief ray (CR) from a central field point at an incidence angle of less than substantially 15°. The system preferably has a numerical aperture greater than 0.18 at the image (IM). The system is preferably configured such that a chief ray (CR) converges toward the optical axis (OA) while propagating between the secondary mirror (M2) and the tertiary mirror (M3).

    摘要: A bundle-guiding optical collector collects an emission of a radiation source and forms a radiation bundle from the collected emission. A reflective surface of the collector is the first bundle-forming surface downstream of the radiation source. The reflective surface is formed such that it converts the radiation source into a family of images in a downstream plane. The family of images includes a plurality of radiation source images which are offset to each other in two dimensions (x, y) in a direction perpendicular to the beam direction of the transformed radiation bundle and are arranged relative to each other in a non-rotationally symmetric manner relative to the beam direction of the transformed radiation bundle. The transformed radiation bundle in the downstream plane has a non-rotationally symmetric bundle edge contour relative to the beam direction of the transformed radiation bundle. The result is a collector in which the radiation bundle shape generated by the collector. In other words, the illumination distribution generated by the collector in a defined manner in the plane downstream of the collector has a shape which is freely selectable to the greatest possible extent.
