The behavior of surface hydrocarbons and carbon during thermal oxidation of silicon is studied. It was established that organic contaminants are readily volatilized and do not affect, in a significant manner, the oxidation kinetics only in the case when the silicon surface during contamination is covered with an oxide at least 5 to 10 Angstrom thick. The organic removal process is substantially more effective at the higher temperatures of oxidation (900°C and above) than at the low temperature of 700°C. In the latter case, a noticeable disruption of the oxidation kinetics due to organic contaminants was observed for hydrophobic surfaces, or surfaces subjected to HF step last.
