Inspection system, inspection method, and process management method

摘要

The present invention relates to an inspection apparatus comprising: an electron emitting unit for sequentially emitting an electron beam in the direction of the inspection area of a sample; a decelerating means for drawing back the electron beam in the vicinity of the inspection area; an imaging unit for forming images of the electron beam, which has been drawn back in the vicinity of the inspection area, on multiple different image forming conditions; an image detecting unit for capturing the electron beam that formed an image corresponding to each image forming condition and an image processing unit for comparing the images on different image forming conditions with one another to thereby detect a defect in the inspection area.
