Patent ID: 8311775

Claim:
A defect repair apparatus, comprising: a defect detection unit operable to (i) inspect a multilayer substrate on which a repetitive pattern is formed (ii) extract positional information of a defect in the repetitive pattern, and (iii) extract feature information of the defect; a database operable to register a plurality of defect repair techniques; a defect repair unit operable to repair the defect of the multilayer substrate using one of the plurality of defect repair techniques; and a control unit operable to (i) read the one of the plurality of defect repair techniques for repairing the defect detected by the defect detection unit from the database based on a layer structure of the multilayer substrate, and (ii) control the defect repair unit that repairs the defect by using the one of the plurality of defect repair techniques, wherein, the database contains (i) layer information for individual layers of the multilayer substrate, and (ii) label information for individual areas of each of the individual layers.
