Paper Abstract

Studies of both superclean silicon wafer surface and subsurface layer have shown high informative possibilities of the light scattering method. It was found that measurements of light scattering indicatrix vs azimuth make it possible to fix the occurrence of atomic steps on the surface studied. The possibility of detecting stacking faults in silicon single crystals is demonstrated by analyzing the intensity of the scattered light with a 442 nm wavelength during scanning of the sample surface with a focused laser beam.
