    摘要: A projection objective of a microlithographic projection exposure apparatus has a correction device which can correct photoinduced imaging errors without optical elements having to be removed for this purpose. The correction device includes a first optical element and a second optical element, whose surface facing the first optical element is provided with a local surface deformation for improving the imaging properties of the projection objective. In a wall, which seals an intermediate space formed between the first optical element and the second optical element, an opening is provided through which the intermediate space can be filled with a fluid. By modifying the refractive index of the fluid adjacent to the surface, the effect of the surface deformation can be modified in a straightforward way.

    摘要: A very-high aperture, purely refractive projection objective is designed as a two-belly system with an object-side belly, an image-side belly and a waist (7) situated therebetween. The system diaphragm (5) is seated in the image-side belly at a spacing in front of the image plane. Arranged between the waist and the system diaphragm in the region of divergent radiation is a negative group (LG5) which has an effective curvature with a concave side pointing towards the image plane. The system is distinguished by a high numerical aperture, low chromatic aberrations and compact, material-saving design.

    摘要: An illumination system for a projection exposure machine, operating with ultraviolet light, for microlithography has an angle-conserving light mixing device with at least one integrator rod that has an entrance surface for receiving light from a light source, and an exit surface for outputting exit light mixed by the integrator rod. At least one prism arrangement for receiving exit light and for varying the state of polarization of the exit light is placed downstream of the integrator rod. A preferred prism arrangement has a polarization splitter surface, aligned transversely to the direction of propagation of the exit light, which passes light fractions with p-polarization without hindrance, and reflects fractions with s-polarization. The separated beams with orthogonal polarization are parallelized by means of a reflecting surface aligned parallel to the polarization splitter surface, and the same state of polarization is set for both partial beams by means of a suitable retarder.

    摘要: In a method for manufacturing semiconductor devices and other finely structured parts, a projection objective (5) is used in order to project the image of a pattern arranged in the object plane of the projection objective onto a photosensitive substrate which is arranged in the region of the image plane (12) of the projection objective. In this case, there is set between an exit surface (15), assigned to the projection objective, for exposing light and an incoupling surface (11), assigned to the substrate, for exposing light a small finite working distance (16) which is at least temporarily smaller in size and exposure time interval than a maximum extent of an optical near field of the light emerging from the exit surface. As a result, projection objectives with very high numerical apertures in the region of NA>0.8 or more can be rendered useful for contactless projection lithography.
