Abstract


The oxygen (O) precipitate growth kinetics from moderate and high germanium (Ge) doped Czochralskigrowth silicon (Cz-Si) are in-situ investigated at 1000 degrees C utilizing high-energy X-ray diffraction and analyzed with respect to precipitate density within a diffusion-driven growth model. Distinct different precipitation kinetics are observed for high Ge doped specimens. From the comparison of three thermal treatments, it was found that even for a high Ge concentration the nucleation rate at 800 degrees C is not influenced, however it facilitates larger grown-in precipitates of smaller amount as compared to the precipitates in undoped and moderately Ge doped samples. However, those grown-in O precipitates can be erased either by a direct annealing at 1200 degrees C or 1000 degrees C, but on the other hand stabilized by an annealing step at 800 degrees C, which in this manner as a drift step of grown-in precipitates for the high Ge-doped samples. In comparison additional nuclei are formed at 800 degrees C in the moderate and undoped cases. (C) 2017 Elsevier B.V. All rights reserved.
