    摘要: A catadioptric projection objective for imaging a pattern provided in an object plane of the projection objective onto an image plane of the projection objective comprises: a first objective part for imaging the pattern provided in the object plane into a first intermediate image; a second objective part for imaging the first intermediate imaging into a second intermediate image; a third objective part for imaging the second intermediate imaging directly onto the image plane; wherein a first concave mirror having a first continuous mirror surface and at least one second concave mirror having a second continuous mirror surface are arranged upstream of the second intermediate image; pupil surfaces are formed between the object plane and the first intermediate image, between the first and the second intermediate image and between the second intermediate image and the image plane; and all concave mirrors are arranged optically remote from a pupil surface. The system has potential for very high numerical apertures at moderate lens material mass consumption.

    摘要: An optical system for ultraviolet light having wavelengths λ≦200 nm, which may be designed in particular as a catadioptric projection objective for microlithography, has a plurality of optical elements including optical elements made of synthetic quartz glass or a fluoride crystal material transparent to a wavelength λ≦200 nm. At least two of the optical elements are utilized for forming at least one liquid lens group including a first delimiting optical element, a second delimiting optical element, and a liquid lens, which is arranged in an interspace between the first delimiting optical element and the second delimiting optical element and contains a liquid transparent to ultraviolet light having wavelengths λ≦200 nm. This enables effective correction of chromatic aberrations even in the case of systems that are difficult to correct chromatically.

    摘要: A catadioptric projection objective which images a pattern arranged in an object plane of the projection objective into the image plane of the projection objective while generating a real intermediate image has a catadioptric objective part having at least one concave mirror and a beam deflecting device and also a dioptric objective part. The imaging system has a system diaphragm having a variable diaphragm diameter for variably limiting the cross section of the radiation passing through the projection objective. This system diaphragm is arranged in the catadioptric objective part, preferably in direct proximity to the concave mirror. The invention enables a projection objective with a simple construction.

    摘要: A projection exposure apparatus has a projection lens with an object plane, an image plane, an optical axis and a non-telecentric entrance pupil. The apparatus further comprises an illumination system having an intermediate field plane and a field stop. The field stop is positioned in or in close proximity to the intermediate field plane and defines an illuminated field in the object plane that does not contain the optical axis of the projection lens. The illumination system is configured such that, in the object plane, a mean of the angles formed between all principal rays emanating from the intermediate field plane on the one hand and the optical axis of the projection lens on the other hand differs from 0°.

    摘要: In certain aspects, catadioptric projection objectives for imaging a pattern from an object field arranged in an object surface of the projection objective onto an image field arranged in an image surface of the projection objective include a first objective part configured to image the pattern from the object surface into a first intermediate image, and having a first pupil surface, a second objective part configured to image the first intermediate image into a second intermediate image, and having a second pupil surface optically conjugate to the first pupil surface, and a third objective part configured to image the second intermediate image into the image surface, and having a third pupil surface optically conjugate to the first and second pupil surface. A pupil mirror having a reflective pupil mirror surface is positioned at or close to one of the first, second and third pupil surface. A pupil mirror manipulator operatively connected to the pupil mirror and configured to vary the shape of the reflective surface of the pupil mirror allows for dynamically correcting imaging aberrations originating from lens heating, compaction and other radiation induced imaging aberrations occurring during operation of the projection objective.
