    摘要: An optical element (14) transparent for radiation with a wavelength λ in the ultraviolet wavelength range below 250 nm, in particular at 193 nm, comprises a substrate (17) with a refractive index nS larger than 1.6, and an antireflection coating (16) formed on at least part of the surface of the substrate (17) between the substrate (17) and an ambient medium with a refractive index nA, preferably with nA=1.0. The antireflection coating (16) consists of a single layer of a material with a refractive index nL of about nL=√{square root over (nAnS)}, in particular nL>1.3, and the optical thickness dL of the single layer is about λ/4. The optical element (14) is preferably part of a projection objective (5) in a microlithography projection exposure apparatus (1) and located adjacent to a light-sensitive substrate (10).

    摘要: In a method for making an optical system for imaging a radiation distribution from an input surface of the optical system into an output surface of the optical system, the optical system has a multiplicity of optical components which determine an imaging quality of the optical system, which are arranged along an optical axis of the optical system and comprise at least one optical component which has a substrate with a substrate surface which is provided for carrying an interference layer system having a layer construction that determines the optical properties of the optical component covered with the interference layer system. The method includes: predefining an optimization target for at least one imaging quality parameter that represents the imaging quality of the system; determining the imaging quality of the optical system while taking account of the layer construction of the interference layer system; and varying the layer construction for approximating the imaging quality parameter to the optimization target. In accordance with the method, the determination of the optimum layer construction is coupled directly with an assessment and of the imaging quality of the total system including the interference layer system to be optimized.

    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 catadioptric projection objective for images an object field onto an image field via imaging radiation. The projection objective includes at least one reflective optical component and a measuring device. The reflective optical component, during the operation of the projection objective, reflects a first part of the imaging radiation and transmits a second part of the imaging radiation. The reflected, first part of the imaging radiation at least partly contributes to the imaging of the object field. The transmitted, second part of the imaging radiation is at least partly fed to a measuring device. This allows a simultaneous exposure of the photosensitive layer at the location of the image field with the imaging radiation and monitoring of the imaging radiation with the aid of the measuring device.
