摘要：A method and device for observing a specimen in which an electron beam isirradiated and scanned from an oblique direction, onto a surface of a calibration

substrate on which a pattern with a known shape is formed, and an SEM image of thesurface of the calibration substrate is obtained. An angle in an oblique direction of theelectron beam irradiated is obtained and is adjusted to a desired angle. The electronbeam is irradiated from the adjusted desired angle in the oblique direction, onto aspecimen substrate on which a pattern is formed, and an SEM image of the specimensubstrate is obtained. The SEM image of the specimen substrate is processed by use ofthe information of the desired angle, and a 3D image of the pattern on the specimensubstrate or a shape of a cross section of the pattern is obtained.
