Abstract:The characteristics of polysilicon-oxide-nitride-oxidesilicon (SONOS) devices with different tunnel oxides are studied. The tunnel oxide fabricated by High-Temperature Oxide (HTO) with additional NO annealing treatment (HTO (NO*)) has better performance than that fabricated by HTO only and In-Situ Steam Generated oxide (ISSG) including operation window, retention, and endurance. Besides, the properties of charge-to-breakdown are also observed. The study can provide a straightforward way of reliability for futu… 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.
