    摘要: A method of matching CD-SEM's to ensure consistent measurements over an installed base of SEM's is disclosed by measuring with each of a plurality of scanning electron microscopes the feature size of resist features in at least two positions on the substrate such that field-to-field variations, and reticle and exposure tool non-uniformities are efficiently suppressed in the matching result.
