High-resolution X-ray photoelectron spectroscopy at 6 keV photon energy was realized by utilizing high-flux-density x rays from the third-generation high-energy synchrotron radiation facility, SPring-8. The method was applied to high-k HfO2/interlayer/Si complementary metal oxide superconductor gate-dielectric structures. Results indicated that SiOxNy as an interlayer was more effective in controlling the interface structure than SiO2.
