Method and system for manufacturing semiconductor devices, and method and system for inspecting semiconductor devices
First Claim
1. A method of inspecting a semiconductor device comprising the steps of:
- acquiring an image of the semiconductor device;
detecting defects in the semiconductor device based upon the image acquired;
determining if any of information of the defects detected is false, and if so, removing such false information;
classifying the defects;
displaying the result of the classification on a display screen; and
determining if any defects were not classified during the step of classifying the defects and classifying those defects not previously classified.

Abstract
The present invention relates to a method and system of inspecting a product, including extracting defects from the product, classifying the defects on the basis of information about the extracted defects representing the analogy of the defects, extracting the feature data of the defects on the basis of the result of defect classification, and feeding back the feature data of the extracted defects for inspection. The method and system is characterized in that the extracted feature data of the defects is fed back for inspecting the product. The present invention also relates to a method of manufacturing a semiconductor electric or electronic device, including extracting defects from the semiconductor electric or electronic device, classifying the defects on the basis of information about the extracted defects representing the analogy of the defects, extracting the feature data on the defects on the basis of the result of defect classification, and feeding back the feature data of the extracted defects to an apparatus for manufacturing the semiconductor electric or electronic device.
