  • Abstract
    This work discusses effects of the substrate on the scavenging of SiO2 interface layer (SiO2-IL) in HfO2 gate stacks. We propose a model that SiO2-IL scavenging occurs through the reaction of the oxygen vacancy (VO) transferred from HfO2 to SiO2 with oxygen formed at SiO2/substrate interface.
