Abstract:
1. A defect review apparatus comprising: a storage device which stores data about a defect of an inspection target object; a first imaging device which captures an image located in a position on a surface of the inspection target object, the position being specified by information regarding the position of the inspection target object which has been input; and a control device which controls the first imaging device; wherein the storage device stores: first defect detection data including a defect number labeling the defect of the inspection target object detected by a first defect detection process, and information regarding the position of the defect; and second defect data including a defect number labeling the defect of the inspection target object detected by a second defect detection process, and information regarding its position; and based on the first defect detection data and the second defect detection data, the control device determines whether or not a same defect is registered in both the first defect detection data and second defect detection data, and if the same defect is registered in both the first defect detection data and the second defect detection data, the control device registers this defect in the storage section as a duplicate defect; and when capturing an image of the defect by the first imaging device, the control device directs capture of an image of the duplicate defect based on the information regarding the position registered in the first defect detection data, and then the control device does not direct capture of an image of the duplicate defect based on the information regarding the position registered in the second defect detection data.
