  • Electron Microscope and Specimen Orientation Alignment Method
    Publication number: 20240087840
    Abstract: An electron microscope includes an irradiation optical system that irradiates a specimen with an electron beam, a specimen stage that supports the specimen, an image forming optical system that forms an image of electrons transmitted through the specimen, an imaging apparatus that captures an image formed by the image forming optical system, and a control unit that controls inclination of the specimen with respect to an incident direction of the electron beam. The irradiation optical system includes an aperture that cuts off a part of the electron beam to be irradiated to the specimen. The control unit acquires an image including Kikuchi bands that appear in a shadow region of the aperture, detects the Kikuchi bands in the shadow region of the aperture in the image, and controls inclination of the specimen with respect to the incident direction of the electron beam, based on the detected Kikuchi bands.
