摘要
High doses of the stable oxygen-18 tracer isotope have been implanted at 200 keV into thick thermal oxide on silicon to study oxide sputtering in conditions similar to the formation of isolated silicon device islands by SIMOX. Final tracer distributions were obtained by secondary ion mass spectrometry confirming the high mobility of oxygen within the silica, diffusion coefficient 1.7 x 10(-12) cm-2 s-1, with rapid desorption of excess oxygen from the top silica surface after perfect isotopic exchange as the oxide layer remains at the stoichiometry of SiO2.
