Abstract:The effect of Ge doped in CZSi on the precipitation and the defect-free zone (DFZ) formation in Ge-doped CZSi wafers after a three step gettering annealing was studied. It is found that Ge not only can promote the out-diffusion of oxygen and form wider DFZ in Ge-Doped CZSi wafer than that in the control sample, but also can suppress the formation of precipitation.
