Abstract:We review some experimental data on the dielectric breakdown (BD) phenomenon under high field stress of important gate insulators used in MOSFETs. We first discuss the case of silicon oxides or oxynitrides in the thickness range of tens of nm down to about 1 nm focusing on the kinetics of the final hard BD event.We describe the dependence of the BD current transient on the oxide thickness and the electric field and voltage. In particular we focus on the progressive BD phenomenon, i.e., a gradual growth of the … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
