| Outline of Final Research Achievements |
In the present research subject, we have investigated background kinetics of metal-germanate formations on germanium substrates by radical-enhanced atomic layer deposition (REALD), where microwave-generated oxygen radicals are used as an oxidant of surface-adsorbed metal precursors, and its application to the formations of gate-dielectrics of Ge-MOSFETs. We have found that argon ions with kinetic energies of ~5 eV enhance the germanate formations. We have also succeeded in the formations of Ge-MOS capacitor with an oxide-equivalent thickness of 1 nm.
