Patent ID: 8045149

Claim:
An apparatus for processing each inspected data obtained by inspections using a plurality of inspection apparatuses, comprising: a data processing unit configured to receive position information, in a first coordinate system, of a first defects group detected on a sample by inspecting the sample under a first condition using a first defect inspection apparatus, and receives position information, in a second coordinate system, of a second defects group detected on the sample after at least one wafer processing step has been performed on the sample, by inspecting the sample under a second condition using a second defect inspection apparatus which is different from the first defect inspection apparatus, said data processing unit including: a position correction unit configured to correct error of relative position information on the first defects group and/or the second defects group, the error being generated by misalignment between the first coordinate system and the second coordinate system, and a defects checking unit which checks the first defects group and the second defects group, having error of the relative position information corrected; and an output unit which outputs the checked results.
