Results of measurements of the thickness of natural oxide on a silicon structure in the form of a set of elements (protrusions) with trapezoidal profile, 2 μm step, width of upper base 10 nm, height of elements 500 nm, and tilt angle of lateral side of element relative to its base 54.7° are presented. The entire structure is covered with a natural oxide that appeared at room temperature. The distance between the {111} planes of silicon is used to assure traceability of the measurements.
