Patent ID: 8263929

Claim:
A standard member for calibrating a scanning electron microscope, wherein the scanning electron microscope measures a pattern within an observation area based on information about an intensity of a secondary electron or a reflected electron generated by scanning an incident electron ray on the observation area on a measurement sample, the standard member comprising: a first pattern area having a convex-concave pattern of a multilayer film cross section formed by laminating different materials periodically at a constant and fixed multi-layer pitch; and a second pattern area having a convex-concave pattern of a multilayer film cross section formed by laminating different materials at a variable multi-layer pitch which provides varying pitch sizes in one direction, wherein the convex-concave patterns of the first pattern area and the second pattern area are arranged adjacently on one axis and at substantially a same height, and wherein the variable multi-layer pitch in the second pattern area includes at least one pitch size for coarse adjustment larger than the fixed multi-layer pitch in the first pattern area and at least one pitch size for high-definition adjustment smaller than the fixed multi-layer pitch in the first pattern area.
