Abstract

See full text

An apparatus for reviewing defects of a semiconductor device is provided to review a lot of defects in a short period of time thereby to improve the efficiency of defect review. A method for reviewing defects of a semiconductor device includes obtaining an image including a defect on the semiconductor device detected by a detection device by use of a scanning electron microscope at a first magnification, making a reference image from the image including the defect obtained at the first magnification, detecting the defect by comparing the image including the defect obtained at the first magnification to the reference image made from the image including the defect at the first magnification, and taking an image of the detected defect at a second magnification that is larger than the first magnification.
