Abstract:A photon-induced leakage current technique to analyze hot carriers is discussed. CMOS photo-leakage test structures are used to determine the spatial dependency of photon-induced leakage current. New trench DRAM test structures are developed for application of the photon-induced leakage technique to analyze hot carriers induced by trench DRAM leakage mechanisms. An analytical model is developed for application of the photonInduced leakage analysis to MOSFET and trench GlDL mechanisms.
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.
