Research of values of distortions of digital SEM images obtained on SEM DSM-960A (CARL Zeiss, Germany) and the accuracy of their consideration
For measurements of digital SEM images of test grid with a resolution 1425 lin/mm taken on a digital SEM DSM-960A (Carl Zeiss, Germany), are defined by their scale and geometric distortion of the SEM magnification range from 1000h to 20000h. Found that the large-scale distortions of digital SEM images obtained in this type of SEM is systematic, regardless of the increase and is approximately -2 % along the x-axis image and -4 % along the y-axis with a picture.
