    摘要: An optical system of a microlithographic projection exposure apparatus contains a module, which can be fitted in the optical system and removed from it as a unit. The module contains a cavity which can be completely filled with a liquid and hermetically sealed, and a concavely curved optical surface which bounds the cavity at the top during operation of the projection exposure apparatus. This makes it possible to fill the module outside the optical system. The module can be tilted there so that no air bubble, which prevents complete filling, can form below the concavely curved optical surface.

    摘要: A device for the optical measurement of an optical system, in particular an optical imaging system, is provided. The device includes at least one test optics component arranged on an object side or an image side of the optical system. An immersion fluid is adjacent to at least one of the test optics components. A container for use in this device, a microlithography projection exposure machine equipped with this device, and a method which can be carried out with the aid of this device are also provided. The device and method provide for optical measurement of microlithography projection objectives with high numerical apertures by using wavefront detection with shearing or point diffraction interferometry, or a Moiré measuring technique.

    摘要: An optical system of a microlithographic projection exposure apparatus (10) contains a module (50; 150), which can be fitted in the optical system and removed from it as a unit. The module contains a cavity (42; 142) which can be completely filled with a liquid (34; 134) and hermetically sealed, and a concavely curved optical surface (S) which bounds the cavity at the top during operation of the projection exposure apparatus (10). This makes it possible to fill the module outside the optical system, The module can be tilted there so that no air bubble, which prevents complete filling, can form below the concavely curved optical surface.

    摘要: A method for producing a perforated mask for particle radiation includes calculating values of an elasticity of adjacent cells of a mask with respect to longitudinal and shear stresses in a main plane of the mask on a model of the desired pattern of mask openings. For the respective individual cells, length and direction of all the edge sections of the openings and cross-sectional areas of the openings are determined. Therefrom, statistical parameters are derived, which are used as a variable in preselected empirical functions to determine the elasticity values of the cells analytically. By linking the elasticity values determined with deformation forces to be expected, the vector field of a distortion of the mask to be expected is calculated by FE calculation. For cutting the mask openings into a blank, a pattern is selected that represents the desired pattern with a distortion being the inverse of the previously calculated distortion.

    摘要: A measuring system for the optical measurement of an optical imaging system, which is provided to image a pattern arranged in an object surface of the imaging system in an image surface of the imaging system, comprises an object-side structure carrier having an object-side measuring structure, to be arranged on the object side of the imaging system; an image-side structure carrier having an image-side measuring structure, to be arranged on the image side of the imaging system; the object-side measuring structure and the image-side measuring structure being matched to each other in such a way that, when the object-side measuring structure is imaged onto the image-side measuring structure with the aid of the imaging system, a superposition pattern is produced; and a detector for the locally resolving acquisition of the superposition pattern. The imaging system is designed as an immersion system for imaging with the aid of an immersion liquid. A structure carrier to be arranged in the region of the immersion liquid is assigned a protective system in order to increase the resistance of the measuring structure to degradation caused by the immersion liquid. A measurement of immersion systems under immersion conditions is thereby possible without detrimental influence of the immersion liquid on the measuring accuracy.
