A physical model responsible for such enhanced degradation in PMOSFETs with oxynitride gate dielectric is proposed. It is shown that the hole injection barrier lowering as a result of the nitrogen-rich layer at the SiO/sub 2//Si interface in oxynitride is responsible for such enhanced degradation.","PeriodicalId":237214,"journal":{"name":"1999 International Symposium on VLSI Technology, Systems, and Applications.
