Method for improving the reproducibility of a coordinate measuring apparatus and its accuracy
Abstract:
A method for improving the reproducibility of a coordinate measuring machine and its accuracy is disclosed. Using at least one measuring field of a camera, a plurality of images of at least one structure on the substrate are recorded. The substrate is placed on a measuring stage traversable in the X coordinate direction and the Y coordinate direction, the position of which is determined during imaging using a displacement measuring system. The measuring field is displaced by the amount of the deviation determined.
