  • Abstract
    Accordingly, we investigated possible NBTI mechanisms and resultant structural changes at Si/SiO2 and Si/SiOxNy interfaces. To determine if it is possible to identify a NBTI-generated structure through XPS of the interface, the N 1s core-level shifts of various structures at the Si/SiOxNy interface were also evaluated. We further considered the important role of hydrogen to localize the hole trapped in the interface
