A method of low-angle mid-IR light scattering is shown to be applicable for the contactless and non-destructive inspection of the internal gettering process in CZ Si crystals. A classifcation of scattering inhomogeneities in initial crystals and crystals subjected to the getting process is presented.
Czochralski-grown boron-doped silicon crystals were studied by the techniques of the low-angle mid-IR-light scattering and electron-beam-induced current. The large-scale accumulations of electrically-active impurities detected in this material were found to be different in their nature and formation mechanisms from the well-known impurity clouds in a float zone-grown silicon. A classifcation of the large-scale impurity accumulations in CZ Si:B is made and point centers constituting them are analyzed in this paper. A model of the large-scale impurity accumulations in CZ-grown Si:B is also proposed.
