Silicon test object of the linewidth of the nanometer range for SEM and AFM

The results of the study of a test object on scanning electron microscopes and atomic force microscopes are presented. The test object presents a relief on a monosilicon surface, and it is fabricated by the anisotropic etching of monosilicon. The relief elements have a trapezoidal profile with large angles of inclination of the sidewalls. The sides of the relief elements coincide with the crystallographic planes {100} and {111} of silicon. The test object is intended for calibration of scanning electron microscopes and atomic force microscopes.
