The three-level and spectroscopic charge pumping techniques, deep level transient spectroscopy and capacitance-voltage measurements are both used to determine the energy distribution of Si–SiO2 interface states on submicrometer metal–oxide–semiconductor field-effect transistors and metal–oxide–semiconductor capacitors. This study is a systematic comparative analysis between charge pumping techniques and capacitance measurements. The measurements have been performed on different structures (n- and p-type materials, low and high interface states densities) and the performances of each technique have been compared.
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.
