摘要: A projection exposure system includes an illumination system configured to illuminate a mask with radiation. The projection exposure system also includes a projection objective configured to project an image of a pattern of the mask onto a radiation-sensitive substrate. The projection exposure system further includes an angle-selective filter arrangement arranged at or close to a field surface of the projection objective in a projection beam path optically downstream of the object surface. The angle-selective filter arrangement is effective to filter radiation incident on the filter arrangement according to an angle-selective filter function.

摘要: A purely refractive projection objective suitable for immersion microlithography is designed as a single-waist system with five lens groups, in the case of which a first lens group with negative refractive power, a second lens group with positive refractive power, a third lens group with negative refractive power, a fourth lens group with positive refractive power and a fifth lens group with positive refractive power are provided. A constriction site of narrowest constriction of the beam bundle lies in the region of the waist. A waist distance AT exists between the object plane and the constriction site X. The condition AT/L≦0.4 holds for a distance ratio AT/L between the waist distance AT and an object-image distance L of the projection objective. Embodiments of inventive projection objectives reach very high numerical apertures NA>1.1 in conjunction with a large image field and are distinguished by a compact overall size and good correction of the lateral chromatic aberration.

摘要: A catadioptric projection lens for imaging a pattern arranged in an object plane onto an image plane, preferably while creating a real intermediate image, including a catadioptric first lens section having a concave mirror and a physical beamsplitter having a beamsplitting surface, as well as a second lens section that is preferably refractive and follows the beamsplitter, between its object plane and image plane. Positive refractive power is arranged in an optical near-field of the object plane, which is arranged at a working distance from the first optical surface of the projection lens. The beamsplitter lies in the vicinity of low marginal-ray heights, which allows configuring projection lenses that are fully corrected for longitudinal chromatic aberration, while employing small quantities of materials, particularly those materials needed for fabricating their beamsplitters.

摘要: A projection objective has at least five lens groups (G1 to G5) and has several lens surfaces. At least two aspheric lens surfaces are arranged so as to be mutually adjacent. These mutually adjacently arranged lens surfaces are characterized as a double asphere. This at least one double asphere (21) is mounted at a minimum distance from an image plane (0′) which is greater than the maximum lens diameter (D2) of the objective.

摘要: A catadioptric projection lens configured for imaging a pattern arranged in an object plane (2) onto an image plane (4) while creating a single, real, intermediate image (3) has a catadioptric first section (5) having a concave mirror (6) and a beam-deflection device (7), and a dioptric second section (8) that commences after the beam-deflection device. The system is configured such that the intermediate image follows the first lens (17) of the dioptric section (8) and is preferably readily accessible. Arranging the intermediate image both between a pair of lenses (17, 21) of the dioptric section and at a large distance behind the final reflective surface of the beam-deflection device helps to avoid imaging aberrations.
