The bondgap were calculated as 2.7eV. The dielectric constant of the multiple-layered films was close relative to the thickness of the covering layer-SiOx, so the thickness had better be reduce. The bonding configurations of multiple-layered films had no evident changes after 400癈 annealing, the thickness raise very little and the dielectric constant increase 8%.
