The A-centers (VO) annealing and transformation of precursors to form stable
СiОi defects during these processes are described. It was found the necessity to take into
account annihilation of vacancy type defects with the interstitial type mobile defects to
describe the annealing of defects. It was shown that the energies of migration for vacancy
(V) and interstitial carbon atoms Сi that are defined by the degree of their localization in
silicon lattice at the temperature close to 550 K are equal Emv = 1.1 eV and Emc = 1.16 eV, accordingly.
