Witrynathat impurity diffusion in oxidizing ambients is enhanced and the enhance- ment clearly depends on oxidation rates, the higher the rate, the larger the enhancement. Oxidation-enhanced diffusion is caused by the supersaturation of extrinsic point defects generated at the Si-SiO2 interface during oxidation. http://web.eng.gla.ac.uk/groups/sim_centre/courses/oxidation/sigrowth_8.html bitch band

Impurity redistribution during oxidation

WitrynaA model of the diffusion-segregation redistribution of phosphorus in an SiO 2 /Si system during thermal oxidation of highly doped silicon layers is developed taking into account the formation of a peak of surface impurity concentration at the interface. The formation of this surface concentration peak is attributed to a change in the free energy of the … WitrynaThe redistribution of impurities during thermal oxidation of silicon has been investigated using the metal‐oxide‐semiconductor (MOS) system. It has been demonstrated that the MOS technique permits a semiquantitative observation of both n‐ and p‐type impurity profiles in the silicon surface region.
