摘要

Two-step (450°C-1000°C) and three-step (1150°C-450°C-1000°C) annealing experiments were carried out to study oxygen precipitation behavior in Czochralski silicon. A distinct retardation of precipitation was observed during the two-step annealing, while the retardation during the three-step annealing was less pronounced. In the three-step annealing, the first high temperature (1150°C) annealing in a N2 ambient caused the retardation of precipitation to occur at short nucleation times. The microstructure characteristics as a function of nucleation (450°C) annealing time were similar in the two-step and three-step annealed samples.
