摘要： 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.

摘要： A scanning electron microscope includes: a liner tube which transmits an electron beam; a scintillator having a through-hole into which the liner tube is inserted; a light guide which guides light generated by the scintillator; a conductive layer provided on a sensitive surface of the scintillator; and a conductive member provided in the scintillator, wherein the shortest distance between the liner tube and the conductive member is shorter than the shortest distance between the liner tube and the conductive layer, a voltage for accelerating electrons is applied to the conductive layer, and the conductive layer and the conductive member have a same potential.

摘要： An image evaluation method includes: a template image acquisition step that designates part of a reference image to acquire a template image; a first comparative image acquisition step that acquires a first comparative image in which the position of the template image is moved in a first direction by a first moving amount relative to the reference image; a first evaluation step that performs a pattern matching process on the template image and the first comparative image and evaluates the template image; a second comparative image acquisition step that acquires a second comparative image in which the position of the template image is moved in a second direction that is orthogonal to the first direction by a second moving amount relative to the reference image; and a second evaluation step that performs the pattern matching process on the template image and the second comparative image and evaluates the template image.
