Abstract

The implantation of Ge in Si has been found to considerably increase the steam oxidation rate of Si under certain conditions. This effect has been studied for a range of implanted ion energies and doses. During steam oxidation, implanted Ge is rejected from the growing oxide and forms a thin layer between SiO2 and Si. Segregated Ge is epitaxial with the underlying Si, and leads to enhanced oxidation of the underlying Si. Evidence suggests that the Ge alters the interfacial kinetics associated with oxide formation.
