    摘要: A method for making a silicon wafer includes the steps of generating and stabilizing embryos that become oxygen precipitates by succeeding thermal annealing applied during a semiconductor device manufacturing process. In the silicon wafer, embryos are substantially removed in a denuded zone, and embryos are distributed at a relatively higher concentration in a bulk region. Also, by controlling behaviors of embryos, a silicon wafer having a desired concentration profile of oxygen precipitates by succeeding thermal annealing is manufactured with high reliability and reproducibility.
