|Abstract:||The roles of hot electrons and hot holes in the generation of interface states in MOSFETs have been a controversial issue, due to the different interpretations of experimental data. In this article, a new physics-based charge-extraction algorithm, based on charge-pumping measurements, is used to investigate the roles of electrons and holes in the generation of interface states in submicrometre p-channel and n-channel MOSFETs. Our results show that while hot holes play an important role in the creation of interface states in submicrometre nMOSFETs, hot electrons are the main contributors to the interface-state generation in submicrometre buried-channel pMOSFETs. Therefore different analysis is required when characterizing the hot-carrier behaviour of pMOSFETs and nMOSFETs.|
