The growth mechanisms of the first steps of silicon oxidation at high temperature were studied. The rapid thermal oxidation under a static pressure (40 or 84 mbar) of oxygen isotopically labelled gas (18O2) has evidenced a linear rapid initial growth rate before the classical linear-parabolic Deal and Grove law prevails. The analyses of the 18O depth profile in oxide films formed by sequential oxidations, under dry 16O2 followed by 18O2, suggest an interpretation accounting for the rapid initial oxidation rate: the appearance during the first seconds of non-oxidized silicon fragments in the freshly formed silica network.
