Abstract:Correlations between reliability and interfacial structure changes of ultrathin silicon oxide gate films grown at 700 °C with in situ pyrolytic-gas passivation (PGP) were investigated. PGP uses a little pyrolytic N2O and NF3 during ultradry oxidation with pure O2 at less than 1 ppb humidity and has a potential for application to future low-temperature device fabrication processes due to the reliability retention of the films. It was found that the reliability for the 700 °C grown PGP films is much like that of… Show more
