Area-Selective Post-Deposition Annealing Process Using Flash Lamp and Si Photoenergy Absorber for Metal/High-k Gate Metal–Insulator–Semiconductor Field-Effect Transistors with NiSi Source/Drain
Abstract:We have proposed an area-selective post-deposition annealing (PDA) process that involves a combination of flash lamp annealing and the use of a Si photoenergy absorber (Si-PEA) for metal/high-k gate last metal-insulator-semiconductor fieldeffect transistors (MISFETs) with NiSi on source/drain (S/D). The process makes it possible to suppress the increase in both the sheet resistance and junction leakage current of NiSi S/D regions. This PDA process also showed optimality for silicide gate electrode formation wi… 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.
