Abstract
Comparison is made for parameters and properties of test objects based on the relief structures with right-angled and trapezoidal profiles, which are used for calibration of scanning electron microscopes (SEMs) and atomic force microscopes (AFMs). Methods of calibration of SEMs and AFMs with help of this test objects are presented. Comparative analysis has shown that trapezoidal structures with large angles of sidewall inclination, created by anisotropic etching of silicon with the (100) orientation of its surface, possess the most universal characteristics. Such structures could be used for development of internationally recognized measures of length in the nanometer range for calibration of SEMs and AFMs.
