Abstract:
An electron microscope includes: an irradiation lens system that irradiates a specimen with an electron beam; an irradiation system deflector that deflects an electron beam incident on the specimen; a specimen tilting mechanism that tilts the specimen; an imaging lens system that forms an electron diffraction pattern or an electron microscope image by using an electron having passed through the specimen; an imaging device that acquires the electron diffraction pattern or the electron microscope image formed by the imaging lens system; and a controller that controls the irradiation system deflector and the specimen tilting mechanism. The controller performs: a process of acquiring a plurality of electron diffraction patters formed by using electron beams having different incidence angles to the specimen, the different incidence angles having been obtained by deflecting the electron beams incident on the specimen by using the irradiation system deflector; a process of calculating a tilt angle of the specimen based on the plurality of electron diffraction patterns; and a process of controlling the specimen tilting mechanism so that the specimen has the calculated tilt angle.
