Abstract

Fill pattern inspection system and method where the fill patterns are inspected to a different criteria than the primary pattern or not inspected at all. The fill pattern images are marked such that they may be identified by easily recognizable shapes or designations to avoid unnecessary inspections and repairs in the fill areas. Alternatively, subresolution markers are placed in an image data for locating fill pattern areas. A software tool is also programmed to automatically detect the subresolution markers during inspection and to inspect the regions on a plate which correspond to the subresolution markers in the image data at a different level of criteria than one which is employed for primary pattern inspection.
