Oxidation Process of Hydrogen Terminated Silicon Surface Studied by Thermal Desorption Spectroscopy

Abstract
The oxidation process of hydrogen terminated silicon surface is investigated by thermal desorption spectroscopy (TDS). Oxidation proceeds by two steps, at about 500°C and 800°C, by the desorption of hydrogen and the consumption of oxygen and water. Oxygen and water are consumed simultaneously, but water consumption does not change with oxygen supply. The oxidation process changes by the presence of the native oxide.
