Abstract:
A projection exposure system ( 10 ) includes: a mask holding device ( 14 ), a substrate holding device ( 36 ), projection optics ( 26 ) imaging the mask structures ( 20 ) onto the substrate ( 30 ) during an exposure process, and a measurement structure ( 48 ) disposed in a defined position with respect to a reference element ( 16 ) of the projection exposure system, which defined position is mechanically uncoupled from the position of the mask holding device. The projection exposure system also includes a detector ( 52 ) arranged to record an image of the measurement structure imaged by the projection optics. During operation of the system, the imaging of the mask structures and of the measurement structure takes place at the same time by the projection optics. An evaluation device ( 54 ) establishes a lateral position of the image of the measurement structure in the area of the detector during the exposure process.

Claim (Index 9):
A projection exposure system for microlithography comprising:\n projection optics arranged to image mask structures onto a substrate during an exposure process, and a measuring apparatus configured to monitor lateral imaging stability of the projection optics comprising: a measurement structure, and a detector arranged to record an image of the measurement structure imaged by the projection optics, wherein the projection optics, the measurement structure, and the detector are arranged and configured such that the projection optics image the mask structures onto the substrate via a first optical path that terminates on the substrate and image the measurement structure onto the detector at the same time via a second optical path that differs from the first optical path and terminates on the detector such that the measurement structure is imaged by means of the projection optics directly onto the detector.
