After intermediate annealing is performed for two hours at 1350 deg.C in an O2 atmosphere containing 1.8% of Ar<+> , high-temperature annealing is performed for two hours at 1350 deg.C in an O2 atmosphere containing 0.5% of Ar<+> . With respect to the single crystal silicon substrate in which ion implantation has been performed, the partial pressure of oxygen in the oxygen partial pressure window process is changed. Thus, a SIMOX substrate having less SFC and less silicon islands may be provided.
