A method of 3D reconstruction by stereo scanning electron microscope images for calculation of the surface profile of two samples comprising trapezoidal protrusions in single-crystal silicon was applied. It is shown that the average value of the protrusions height calculated by 3D reconstruction differs from atomic force microscope (AFM) results by 2.3 % for the first sample.
