TLDR
In this paper, the growth kinetics of SiO2 films grown on silicon at 950 to 1100°C in an O2/N2 mixture was empirically studied, and it was found that a linear-parabolic law is in excellent agreement with the oxidation data under the oxygen partial pressure PO2 of 1 or 10−1 atm.
Abstract
Oxide growth kinetics of SiO2 films grown on silicon at 950 to 1100 °C in an O2/N2 mixture is empirically studied. It is found that a linear‐parabolic law is in excellent agreement with the oxidation data under the oxygen partial pressure PO2 of 1 or 10−1 atm. However, a parabolic law is obtained at 10−2 atm, and an inverse‐logarithmic law at 10−3 atm. The Mott‐Cabrera oxidation rate equation is adapted to the thermal oxidation of silicon in the case of PO2≲10−2 atm. Finally, 43.9 kcal/mole is derived as the activation energy value of silicon atoms entering into the oxide.

Electron spectroscopic analysis of the SiO2/Si system and correlation with metal–oxide–semiconductor device characteristics

TL;DR: In this article, the ESCA measurement results on thin SiO2/Si samples are examined comprehensively, critically, and in detail to show that it is possible to correlate these results with MOS (metaloxide-semiconductor) device characteristics such as flatband (threshold) voltage, oxide breakdown field, mobile ion density, hole and electron trap density, and hot-carrier lifetime.
