摘要
By means of low-temperature （10 K） Fourier transform infrared absorption spectroscopy, the kinetics of nitrogen indiffusion in Czochralski （CZ） silicon annealed at 1150-1250℃ in nitrogen ambient is investigated. Moreover, the nitrogen diffusivities in CZ silicon at elevated temperatures deduced herein are in good agreement with those previously obtained in float-zone silicon, thus leading to the conclusion that the nitrogen indiffusion in CZ silicon at elevated temperatures is via nitrogen pairs.
