Electrons that are incident on a specimen are back scattered and appear to emerge from the specimen. These backscattered electrons and secondary electrons can be seen in the shape and the composition of the specimen’s surface. In this research, we created a three-dimensional scattering trajectory program to examine beam-specimen interactions by using Monte-Carlo techniques, and we obtained the yields of backscatter electrons and the secondary electrons protruding from the surface of the specimen. Using this program, we analyzed the properties of the secondary electrons and the backscatter electrons according to the energy distribution of the incident electrons, the shape of the surface, and the composition of the specimen, and we made different models to create two-dimensional images by using Monte-Carlo simulations.
