摘要:
A standard member for automatically, stably, and highly accurately performing magnification calibration used in an electron microscope, the standard member including, on the same plane, a multilayer film cross section formed by alternately laminating materials different from each other, a plurality of first mark patterns arranged across a first silicon layer and in parallel to the multilayer film cross section, at least a pair of second mark patterns arranged across a second silicon layer thicker than the first silicon layer on the opposite side of the first mark patterns with respect to the multilayer film cross section and in parallel to the multilayer film cross section, and a silicon layer arranged on the outer side of the first mark patterns and the second mark patterns with respect to the multilayer film cross section.
