    摘要: The disclosure relates to a microlithographic projection exposure apparatus and a microlithographic projection exposure apparatus, as well as related components, methods and articles made by the methods. The microlithographic projection exposure apparatus includes an illumination system and a projection objective. The illumination system can illuminate a mask arranged in an object plane of the projection objective. The mask can have structures which are to be imaged. The method can include illuminating a pupil plane of the illumination system with light. The method can also include modifying, in a plane of the projection objective, the phase, amplitude and/or polarization of the light passing through that plane. The modification can be effected for at least two diffraction orders in mutually different ways. A mask-induced loss in image contrast obtained in the imaging of the structures can be reduced compared to a method without the modification.

    摘要: A method of qualifying a diffraction grating comprises performing plural measurements by illuminating a region of the grating with a beam of measuring light and detecting an intensity of measuring light diffracted by the grating into a 0th diffraction order. A wavelength of the measuring light or a polarization of the measuring light or an angle of incidence of the measuring light onto the diffraction grating is varied between subsequent measurements. A shape parameter of diffracting elements forming the grating comprises a pitch, height or width of structural features of the diffracting elements. The shape parameter is advantageously used in analyzing interferometric measurements performed on optical surfaces during manufacture of optical elements of a high accuracy.
