Title: Behavior of nitrogen in Si crystal during irradiation and post-annealing

Radiation induced complexes in nitrogen (N) -doped silicon crystal was investigated by highly sensitive infrared absorption spectroscopy. The absorption by N{sub 2} pair was reduced by the electron irradiation in FZ crystals. The absorptions appeared on both sides of N{sub 2} line at 766 cm{sup −1}, at about 725 and 778 cm{sup −1}. By the annealing, N{sub 2} lines recovered a little at 600 °C and mostly at 800 °C. The above new absorption lines reduced by the annealing at lower temperatures and other absorption appeared. In CZ silicon, N{sub 2} lines did not change by the irradiation. Dominant absorption in low carbon FZ silicon was that of C-rich type complexes, VO and I{sub n}C{sub i}O{sub im}(n=0–3, m=0,1). Dominant absorption in the irradiated low carbon CZ silicon was that of C-lean type complexes I{sub n}O{sub 2+mi}(n=1, 2, m=0, 1), and the decrease of C-lean type O{sub 2i} and TDD was observed. By the annealing of CZ Si, VO{sub n} (n=2–4) formation and annihilation was observed.
