    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: A catadioptric projection objective for imaging a pattern onto an image plane includes: a first objective part for imaging the pattern into a first intermediate image; a second objective part for imaging the first intermediate image into a second intermediate image; and a third objective part for imaging the second intermediate image onto the image plane. A first concave mirror having a continuous mirror surface and a second concave mirror having a continuous mirror surface are upstream of the second intermediate image. A pupil surface is 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. A plate having essentially parallel plate surfaces is positioned in the first objective part near the pupil surface. At least one plate surface is aspherized to correct for aberrations.

    摘要: A catadioptric projection objective for imaging an off-axis object field arranged in an object surface of the projection objective onto an off-axis image field arranged in an image surface of the projection objective has a front lens group, a mirror group comprising four mirrors and having an object side mirror group entry, an image side mirror group exit, and a mirror group plane aligned transversly to the optical axis and arranged geometrically between the mirror group entry and the mirror group exit; and a rear lens group. The mirrors of the mirror group are arranged such that at least one intermediate image is positioned inside the mirror group between mirror group entry and mirror group exit, and that radiation coming from the mirror group entry passes at least four times through the mirror group plane and is reflected at least twice on a concave mirror surface of the mirror group prior to exiting the mirror group at the mirror group exit. The mirror group entry is positioned in a region where radiation exiting the front lens group has an entry chief ray height. A second reflecting area is positioned in a region where radiation impinging on the second mirror has a second chief ray height deviating from the entry chief ray height in a first direction; and a fourth reflecting area is positioned in a region where radiation impinging on the fourth mirror has a fourth chief ray height deviating from the entry chief ray height in a second direction opposite to the first direction.
