    Abstract:
    The rate of oxygen precipitation in Czochralski-grown silicon with oxygen supersaturation ratios s greater than 5 and s less than 5 at 1000 degree C was studied as a function of surface processing. Reference samples were compared with samples diffused with high-concentration phosphorus or arsenic layers in N//2 or O//2 ambients. Oxygen precipitation was also studied in samples with air-abraded surfaces. It was found that for s greater than 5 the concentration of oxygen in SiO//2 precipitates in P diffused wafers did not equal the change in intersititial oxygen, and a high density of stacking faults were seen in the bulk. It is concluded that the point defects generated from damaged surfaces and P-diffused surfaces are not the same as those generated from an undoped surface during oxidation. A model describing the effect of surface-generated vacancies and silicon self-interstitials on oxygen precipitate nucleation and growth is discussed.
