Beschreibung
Zusammenfassung:	A projection exposure apparatus for semiconductor lithography having a projection optical unit. The projection optical unit includes a sensor frame, a carrying frame, and a module. The module includes an optical element and actuators for positioning and orienting the optical element. The module is on the carrying frame, and the sensor frame is a reference for the positioning of the optical element. The module includes an infrastructure which includes interfaces for separating a module from the projection optical unit. A method exchanges the module of a projection optical unit of a projection exposure apparatus for semiconductor lithography, wherein the module includes an optical element, while the reference remains in the projection exposure apparatus.
