A calibration standard, for calibrating lateral or angular dimensional
measurement systems, is provided. The standard may include a first
substrate spaced from a second substrate. The standard may be
cross-sectioned in a direction substantially perpendicular or
substantially non-perpendicular to an upper surface of the first
substrate. The cross-sectioned portion of the standard may form a viewing
surface of the calibration standard. The standard may include at least
one layer disposed between the first and second substrates. The layer, or
a feature etched into the first or second substrate or a feature etched
into the layer may have a traceably measured thickness or may be oriented
at a traceably measured angle with respect to the viewing surface. A
thickness or angle of the layer or other feature may be traceably
measured using any technique for calibrating a measurement system with a
standard reference material traceable to a national testing authority.
