Abstract:
An inspection system, comprising:an inspection means that detects the positions and size of particles or pattern defects with which an inspected object is provided; a storage means that is connected to the inspection means via a network and stores inspection data that the inspection means detected and obtained and kill ratio computation data for the position and size of the particles or pattern defects in a device that is formed in the inspected object, wherein the storage means further stores a decision result of good products and bad products in a probing test of an inspected object and the inspection data detected by the inspection means and the kill ratio computation data are created from the decision result of the good and bad products in the probing test; and a computation means that computes kill ratios of individual particles or pattern defects based on the inspection data and the kill ratio computation data and kill ratios for every device that comprises the inspected object from the kill ratio of every individual particle or pattern defect.
