Abstract:
1. A pattern inspection apparatus comprising: substrate holding means for holding a substrate on which a pattern is formed; application means for applying a laser beam, a beam, or a charged particle beam to the substrate held by said substrate holding means; detection means for detecting a signal generated from the substrate by the application; storage means for imaging and storing the signal detected by said detection means; comparison means for comparing the image stored in said storage means with an another image formed from a pattern identical in design; determination means for determining if defects are detected in the pattern based on the comparison result of said comparison means; display means having a map display part where positions of defects on the substrate are displayed as a map, an image display part where defect images are displayed, a list display part where a list of defect information is displayed, and a graph display part where statistical information on selected defect items is displayed as a graph; and area selection means for selecting an area included in the map displayed in said map display part, wherein, when a map area is selected by said area selection means, a list of defect images of defects in the selected map area is displayed in said image display part, a list of defect information on defects in the selected map area is displayed in said list display part, and a graph of statistical information on defects in the selected map area is displayed in said graph display part.
