Thereby, automatic movement to the position to be reviewed, acquisition of image and classification can be realized. On the occasion of identifying the position to be reviewed on a sample and forming an image through irradiation of electron beam on the basis of the positional information of defect detected with the other inspection instrument, an electrical defect can be reviewed with the voltage contrast mode by designating the electron beam irradiation condition, detectors and detecting condition depending on a kind of defect to be reviewed. The image obtained is automatically classified in the image processing unit and the result is then additionally output to the defect file.
