ABSTRACT
An anomalous increase in oxidation rate was observed during low-temperature thermal oxidation of very high dose (5×1016, 7×1016/cm2) As+ ion implanted silicon. Oxidation of Si at 850 °C was faster than that at 950 °C. This effect was attributed to the snowplowing of arsenic (which was more pronounced at lower temperatures) creating a glassy Si-O-As layer near the Si-SiO2 interface.
