Ultrathin SiON films formed by thermal nitridation of SiO2 films were investigated. High-resolution angle-resolved photoelectron spectroscopy was used to investigate the interfacial chemistry of the films. The second-nearest-neighbor effect in the chemical shift was also taken into account. The valence-band offsets of the films were determined to be 4.4 eV.
