摘要: A microlithography projection optical system is disclosed. The system can include a plurality of optical elements arranged to image radiation having a wavelength λ from an object field in an object plane to an image field in an image plane. The plurality of optical elements can have an entrance pupil located more than 2.8 m from the object plane. A path of radiation through the optical system can be characterized by chief rays having an angle of 3° or more with respect to the normal to the object plane. This can allow the use of phase shifting masks as objects to be imaged, in particular for EUV wavelengths.

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 transversely 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.
