Claim One:
1. A system for analyzing defects in electronic circuit patterns, comprising: inspecting an object to detect structural defects during a production process and obtaining position information of said structural defects; detecting images of said structural defects using said position information of said defects; performing an electronic test on said first object after said production process is completed to detect electrical faults in said first object and obtain position information of said electrical faults; comparing said position information of said structural defects with said position information of said electrical faults and extracting corroborated defects having common position information between said structural defects and said electrical faults; classifying images of extracted corroborated defects into critical defect images and non-critical defect images based on a pre-stored classification rule which defines critical and non-critical defects by referring to images of defects, position information of said defects, and results of performing the electronic test to each other; displaying images of classified defects on a screen by discriminating between said critical defect images and said non-critical defect images; modifying said pre-stored classification rule by correcting classification of classified defect images displayed on the screen; and repeating the inspecting operation through the modifying operation for each subsequent object, wherein for each present object under inspection, using a modified pre-stored classification rule with respect to a previous object, as the pre-stored classification rule for the operations with respect to the present object.
