Abstract:SummaryIn summary, we find it is possible to model the extent of diffusion during spike anneals with varying ramp rates by considering the full thermal cycle. These models allow the optimization of RTP ammealing cycles considering the trade-offs between junction depth and sheet resistance. For example, with 1050°C spike anneals, the active dose (and thus sheet conductivity) varies approximately linearly with junction depth. However, faster ramp rates allow the use of higher spike temperatures, with associated …
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific 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 researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
