Abstract:
A microlithographic projection exposure apparatus ( 10 ) includes a projection lens ( 26 ) that images an object field ( 22 ) arranged in a mask plane ( 24 ) onto a substrate ( 28 ) during exposure operation of the projection exposure apparatus, and an illumination system ( 16 ) that has: an exposure illumination beam path ( 44 ) for radiating illumination radiation ( 14 ) onto the object field on the illumination side with respect to the mask plane, a measurement illumination beam path ( 48 ) for irradiating a measurement structure ( 54 ) arranged in the mask plane with the illumination radiation, and a scattering structure ( 50 ) arranged on the illumination side with respect to the mask plane and outside the exposure illumination beam path. The measurement illumination beam path extends via the scattering structure and runs rectilinearly between the scattering structure and the mask plane.

Claim (Index 14):
Method for measuring an imaging aberration at a microlithographic projection exposure apparatus comprising a projection lens configured to image an object field arranged in a mask plane onto a substrate during exposure operation of the projection exposure apparatus, and an illumination system comprising a facet mirror comprising a plurality of mirror elements configured to radiate illumination radiation, during the exposure operation, onto the object field via various radiation channels, wherein the method comprises:\n arranging a measurement structure in the mask plane, and arranging at least one of the mirror elements in a measurement position, in which a beam path of the illumination radiation that extends via the mirror element arranged in the measurement position is directed onto a scattering structure, wherein the illumination radiation scattered at the scattering structure is directed to impinge on the measurement structure.
