      The effect of postdeposition annealing in vacuum and in dry O2 on the atomic transport and chemical stability of chemical vapor deposited ZrSixOy films on Si is investigated. Rutherford backscattering spectrometry, narrow ...

    • Thermal behavior of hafnium-based ultrathin films on silicon 

      Pezzi, Rafael Peretti; Morais, Jonder; Dahmen, Silvio Renato; Bastos, Karen Paz; Miotti, Leonardo; Soares, Gabriel Vieira; Baumvol, Israel Jacob Rabin; Freire Junior, Fernando Lazaro (2003) [Artigo de periódico]
      We report here on the thermodynamical stability of ultrathin, hafnium-based dielectric films, namely hafnium oxide (HfO2), silicate (HfSixOy), and aluminum silicate (AlHfxSiyOz), deposited on silicon. These materials are ...

    • Thermal stability and diffusion in gadolinium silicate gate dielectric films 

      Landheer, Dolf; Wu, Xiaohua; Morais, Jonder; Baumvol, Israel Jacob Rabin; Pezzi, Rafael Peretti; Miotti, Leonardo; Lennard, W.N.; Kim, Joon-Kon (2001) [Artigo de periódico]
      Gadolinium silicate films on Si(100) annealed in oxygen and vacuum at temperatures up to 800 °C were analyzed by Rutherford backscattering and narrow resonance nuclear profiling. Oxygen diffused into the film eliminating ...
