Abstract: Oxygen precipitation in conventional heavily B-doped Czochralski (CZ) silicon (HB-Si) and heavily Ge-B codoped CZ silicon (Ge codoped HB-Si) subjected to single step annealing at 650～1150℃ for 64h or low-high two step annealing(650℃/16h＋1000℃/16h and 800℃/4～128h＋1000℃/16h) are comparatively investigated.It is found that the density of bulk microdefects (BMDs) in Ge codoped HB-Si is much lower than that in HB-Si.The mechanism of which is preliminarily discussed.

Key words: heavily boron-doped Czochralski silicon, germanium, oxygen precipitation
