  • Publication number: 20240085800
    Abstract: A component for a projection exposure apparatus for semiconductor lithography, comprises an optical element and an actuator, which are force-fittingly connected to each other. The actuator at least locally deforms the optical element. The actuator can be configured to minimize the loss in rigidity at the peripheries delimiting the actuator on the imaging quality. A method for designing a component of projection exposure apparatus is provided.

  • Publication number: 20230400772
    Abstract: A method for swapping an optical system, such as a DUV mirror, of a projection exposure apparatus, comprises: a) raising the optical system along a centre axis of the optical system so that mount struts of the optical system pass out of contact with frame struts of a frame carrying the optical system; b) rotating the optical system about the centre axis so that the mount struts are arranged between the frame struts; c) lowering the optical system along the centre axis; and d) shifting the optical system perpendicularly to the centre axis so that the optical system is moved out of a housing.
