Abstract:Deep submicron CMOS technology for low-power, low-voltage applications requires the use of symmetric n+/p+ poly gate structures. This requirement introduces a number of processing challenges, involving fundamental issues of atomic diffusion over distances of 1Å to ∼30μm. Two of the critical issues are dopant cross-diffusion between P- and NMOS devices with connected gates, resulting in large threshold voltage shifts, and boron penetration through the gate oxide. We show that in devices with W-polycide dual-gat… 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.
