or P+ dopants the work function can be tuned over Abstract the whole Si band-gap guaranteeing suitable threshold voltages for both PMOS and NMOS devices. In complete analogy, the ideal metal gate In this paper, we show that TOtally Sllicided should consist of one single material, the work (TOSI) gate electrodes offer an interesting and function of which can be tuned by a comparably industrially viable option for the integration of simple process in order to match the PMOS and metal gate electrodes in advanced CMOS NMOS requirements. Equally important, the technologies as their integration requires only few integration of the new gate material, in particular modifications with respect to a CMOS standard the gate patterning, should be comparably easy than flow. Moreover, the use of NiSi gives access to an for poly-Si. Both requirements can be met using electrode with a tunable mid-gap work function. silicides as gate electrodes. Historically, it has been The potential of TOSI-gate devices is demonstrated shown for the first time in 2001 that a metal gate
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.
