Abstract

An inspection apparatus comprising an electron emitting unit for sequentially emitting an electron beam in the direction of an inspection area of a sample; a deceleration unit for drawing back the electron beam in the vicinity of the inspection area; an imaging unit for forming images of the drawing back electron beam 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 detect a defect in the inspection area.
