    摘要: A REMA objective 123 images an object plane 1 onto the reticle plane 33 and has a lens group 300 disposed in the half of the objective close to the reticle. The object plane 1 lies at a finite spacing. In the lens group 300, the principal ray elevations are greater in magnitude than the elevations of the peripheral rays. A scattering surface 28 is arranged in the lens group 300 having a largest magnitude of sine of the angle of incidence of the principal ray in air with respect to the surface normal (.vertline.sin (i.sub.princ).vertline.) greater than 0.35 and preferably greater than 0.5.

    摘要: A facet mirror is to be used as a bundle-guiding optical component in a projection exposure apparatus for microlithography. The facet mirror has a plurality of separate mirrors. For individual deflection of incident illumination light, the separate mirrors are in each case connected to an actuator in such a way that they are separately tiltable about at least one tilt axis. A control device, which is connected to the actuators, is configured in such a way that a given grouping of the separate mirrors can be grouped into separate mirror groups that include in each case at least two separate mirrors. The result is a facet mirror which, when installed in the projection exposure apparatus, increases the variability for setting various illumination geometries of an object field to be illuminated by the projection exposure apparatus. Various embodiments of separate mirrors for forming the facet mirrors are described.

    摘要: An EUV collector for collecting and transmitting radiation from an EUV radiation source includes at least one collector mirror for reflecting an emission of the EUV radiation source, which is rotationally symmetric with respect to a central axis. The EUV collector also includes a cooling device for cooling the at least one collector mirror. The cooling device has at least one cooling element, which has a course with respect to the collector mirror, in each case, such that the projection of the course into a plane perpendicular to the central axis has a main direction, which encloses an angle of at most 20° with respect to a predetermined preferred direction. The collector transmits improved quality radiation to illuminate an object field.

    摘要: An illumination optics for EUV microlithography illuminates an object field with the aid of an EUV used radiation beam. Preset devices preset illumination parameters. An illumination correction device corrects the intensity distribution and/or the angular distribution of the object field illumination. The latter has an optical component to which the used radiation beam is at least partially applied upstream of the object field and which can be driven in a controlled manner. A detector acquires one of the illumination parameters. An evaluation device evaluates the detector data and converts the latter into control signals. At least one actuator displaces the optical component. During exposures, the actuators are controlled with the aid of the detector signals during the period of a projection exposure. A maximum displacement of below 8 μm is ensured for edges of the object field towards an object to be exposed. The result is an illumination optics that is used to ensure conformance with preset illumination parameters even given the most stringent demands upon precision.

    摘要: A microlithography reduction objective formed from six mirrors arranged in a light path between an object plane and an image plane is provided. The microlithography reduction objective is characterized by having an image-side numerical aperture NA≧0.15. In some embodiments, the mirror closest to the image plane, i.e., the fifth mirror is arranged such that an image-side optical free working distance is greater than or equal to a used diameter of a physical mirror surface of the fifth mirror, a physical mirror surface being the area of a mirror where light rays from the object impinge. The fifth mirror may be arranged such that an image-side optical free working distance is greater than or equal to the sum of one-third the used diameter of the physical mirror surface on the fifth mirror and a length between 20 mm and 30 mm. The fifth mirror may be arranged such that the image-side optical free working distance is at least 50 mm, as well. The image-side free working distance is the physical distance between the vertex of the surface of the fifth mirror and the image plane. Other embodiments are described.
