Standard reference component for calibration, fabrication method for the same, and scanning electron microscope using the same

摘要

The present invention provides a standard reference component for calibration for performing magnification calibration used in the scanning electron microscope with high precision, and provides a scanning electron microscope technique using it. Provided is a standard reference component for calibration for calibrating a scanning electron microscope that measures a length of a pattern in an observation area from information on the intensity of secondary electrons or reflected electrons generated by scanning an incident electron beam in the observation area on a measuring sample, having: a first substrate on which a multiple-layer is laminated and a second substrate with a recess for holding the first substrate, wherein the first substrate is held in the recess of the second substrate so that a normal direction of the multiple-layer surface may be roughly perpendicular to a normal direction of the second substrate surface, and the multiple-layer has a multiple-layer structure of a film containing silicon and a film containing molybdenum.
