Zusammenfassung:Defects observed by imaging tools may be classified by automatic comparison of features observed in a defect image with design information relating to corresponding portions of the image. Defect information may be generated from a defect image from a defect imaging tool. Design information relating to one or more structures to be formed on the substrate in a vicinity of the defect may be retrieved. The defect may be classified based on a combination of the defect information from the defect image and design information relating to one or more structures to be formed on the substrate in the vicinity of the defect.
