Abstract

Dielectric breakdown (BD) of nFETs with TiN metal gates and HfO 2 /interfacial layer with 1.09 nm EOT is studied. Occurrence of progressive BD at low current levels is demonstrated. A new measurement methodology for extraction of the PBD time and its dependence on gate voltage are reported.
