    摘要: As a preliminary stage in manufacturing a lens or lens part for an objective, in particular a projection objective for a microlithography projection system, an optical blank is made from a crystal material. As a first step in manufacturing the optical blank, one determines the orientation of a first crystallographic direction that is defined in the crystallographic structure of the material. The material is then machined into an optical blank so that the first crystallographic direction is substantially perpendicular to an optical blank surface of the optical blank. Subsequently, a marking is applied to the optical blank or to a mounting element of the optical blank. The marking has a defined relationship to a second crystallographic direction which is oriented at a non-zero angle relative to the first crystallographic direction.

    摘要: A microlithographic illumination method for imaging a pattern arranged in an object plane of a projection lens onto an image plane of the projection lens, under which a special means for optically correcting the optical path lengths of s-polarized and p-polarized light such that light beams of both polarizations will either traverse essentially the same optical path length between the object plane and the image plane or any existing difference in their optical path lengths will be retained, largely independently of their angles of incidence on the image plane, which will allow avoiding contrast variations due to pattern orientation when imaging finely structured patterns, is disclosed. The contrast variations may be caused by uncorrected projection lenses due to their employment of materials that exhibit stress birefringence and/or coated optical components, such as deflecting mirrors, that are used at large angles of incidence.

    摘要: An optical system of a microlithographic projection exposure apparatus includes a wavefront correction device which has a plurality of fluid outlet apertures. The apertures are arranged so that fluid flows emerging from the outlet apertures enter a space through which projection light propagates during operation of the apparatus. A temperature controller sets the temperature of the fluid flows individually for each fluid flow. The temperature distribution is determined such that optical path length differences caused by the temperature distribution correct wavefront deformations.

    摘要: A catadioptric projection objective has a multiplicity of lenses and at least one concave mirror, and also two deflection mirrors in order to separate a partial beam path running from the object field to the concave mirror from the partial beam path running from the concave mirror to the image field. The deflection mirrors are tilted relative to the optical axis of the projection objective about tilting axes running parallel to a first direction (x-direction). The first deflection mirror is arranged in optical proximity to a first field plane and the second deflection mirror is arranged in optical proximity to a second field plane, which is optically conjugate with respect to the first field plane. A displacement device for the synchronous displacement of the deflection mirrors is provided. The deflection mirrors have different local distributions of their reflection properties in first and second reflection regions, respectively.
