摘要:
A projection exposure tool for microlithography for exposing a substrate is disclosed. The tool includes a projection objective. The tool also includes an optical measuring apparatus for determining a surface topography of the substrate before the substrate is exposed. The measuring apparatus has a measuring beam path which extends outside of the projection objective. The measuring apparatus is a wavefront measuring apparatus configured to determine topography measurement values simultaneously at a number of points on the substrate surface.
