Abstract: A scanning electron microscope having a charged particle device that processes a specimen using a charged particle beam, the scanning electron microscope includes: an electron source; a secondary-electron detector that detects secondary electrons generated from the specimen; a backscattered-electron detector that is disposed closer to the electron source than a detection surface of the secondary-electron detector to detect backscattered electrons generated from the specimen; a shielding plate for shielding a detection surface of the backscattered-electron detector; and a moving mechanism that moves the shielding plate. In a state where the shielding plate is moved by the moving mechanism so as to shield the detection surface of the backscattered-electron detector, the shielding plate is located between the detection surface of the backscattered-electron detector and the detection surface of the secondary-electron detector.

Abstract: The invention relates to an image capture assembly and method for use in an electron backscatter diffraction (EBSD) system. An image capture assembly comprises a scintillation screen (10) including a predefined screen region (11), an image sensor (20) comprising an array of photo sensors and a lens assembly (30). The image capture assembly is configured to operate in at least a first configuration or a second configuration. In the first configuration the lens assembly (30) projects the predefined region (11) of the scintillation screen (10) onto the array and in the second configuration the lens assembly (30) projects the predefined region (11) of the scintillation screen (10) onto a sub-region (21) of the array. In each of the first and second configurations the field of view of the lens assembly (30) is the same.

Abstract: A charged particle beam device is provided that performs proper beam adjustment while suppressing a decrease in MAM time, with a simple configuration without adding a lens, a sensor, or the like. The charged particle beam device includes: an optical element which adjusts a charged particle beam emitted from a charged particle source; an adjustment element which adjusts an incidence condition of the charged particle beam with respect to the optical element; and a control device which controls the adjustment element, wherein the control device determines a difference between a first feature amount indicating a state of the optical element based on the condition setting of the optical element, and a second feature amount indicating a state where the optical element reaches based on the condition setting and executes adjustment by the adjustment element when the difference is greater than or equal to a predetermined value.

Abstract: A method for evaluating a specimen, the method can include positioning an energy dispersive X-ray (EDX) detector at a first position; scanning a flat surface of the specimen by a charged particle beam that exits from a charged particle beam optics tip and propagates through an aperture of an EDX detector tip; detecting, by the EDX detector, x-ray photons emitted from the flat surface as a result of the scanning of the flat surface with the charged particle beam; after a completion of the scanning of the flat surface, positioning the EDX detector at a second position in which a distance between the EDX detector tip and a plane of the flat surface exceeds a distance between the plane of the flat surface and the charged particle beam optics tip; and wherein a projection of the EDX detector on the plane of the flat surface virtually falls on the flat surface when the EDX detector is positioned at the first position and when the EDX detector is positioned at the second position.
