Patent ID: 8290241

Claim:
An analyzing apparatus which selects an inspection recipe with which defects to be inspected of a kind desired by a user can be detected maximally or with which defects of a kind not desired by the user can be detected minimally from among a plurality of inspection recipes prepared previously when inspection recipes for an inspection apparatus which inspects defects to be inspected are to be set, comprising: a defect information memory part which sets each of the plurality of inspection recipes in the inspection apparatus and receives defect information including, as a minimum, defect identification information (ID), defect coordinates and attribute data of defects which result from inspecting the same defect to be inspected by means of the inspection apparatus to store the defect information; a sampling information producing part which calculates a logical sum of defect IDs specifying common defect positions among the inspection recipes from defect positions obtained by the respective inspection recipes, and produces sampling information from the logical sum of the defect IDs; a review result information memory part which receives review result information from a defect review apparatus, which obtains an image of a position corresponding to the logical sum of the defect IDs, observed by the defect review apparatus, and which prepares kind information for each defect recognized from image information of each of the sampled defects to store the review result information; an analysis designation receiving part which receives kind information of defects to be analyzed by the user; a recipe analyzing part which specifies defect ID information of defects in the review result information corresponding to kind information designated by the user, specifies a state of a defect included in defect ID information by judging the state of the defect observed by the defect review apparatus and comparing the judged state of the defect with a feature amount included in the defect ID information, and calculates a reference value from attribute data of the defect information of the specified defect ID information, calculates distances of attribute data for all detected defects contained in the defect information from the calculated reference value, and counts a number of defects having the distance which is less than or equal to a predetermined threshold as a number of similar defects for each inspection recipe; and an output part which presents the number of similar defects for each inspection recipe to the user.
