Introduction
Surface roughness measurements of fine ceramic thin films at the nanometer scale by atomic force
microscopy is widely applied to quality control and assurance in industries.
One frequently occurring issue in roughness measurements by atomic force microscopy resulting from its
scale dependency is the deviation of roughness due to wear of the probe tip or the deviation in the curvature
of commercially available probe tips. This makes it difficult to obtain a reliable and reproducible result of
the roughness measurement. Therefore, it is highly desirable to standardize a method to evaluate probe tip
diameter or curvature radius.
This document covers the evaluation of probe-tip diameter and provides a method to judge the adequateness
of a probe tip for use in day-to-day roughness measurements of fine ceramic thin films with a certain
arithmetical mean roughness in the range needing the use of atomic force microscopy in production lines or
quality assurance processes.
It should be noted that because surface roughness is a scale-dependent metrology parameter, it is unavoidable
that the probe-tip evaluation process contains some contradictory procedures, namely the adequateness of
the probe tip for a roughness measurement depends on unmeasurable true roughness in a scale of interest.
In this document, the parameters based on roughness profiles are used. The roughness profile is obtained
by using a low-pass filter according to ISO 16610-21. The process to obtain the sampling length, which is
identical to cut-off wavelength, is given in ISO 21920-2. Some different sampling lengths to process a primary
profile can be applied to obtain appropriate values of arithmetic mean deviation of a roughness profile, if
necessary.
