This paper aims to provide insights into the thermal, analog, and RF attributes, as well as a novel modeling methodology, for the FinFET at the industry standard 5nm CMOS technology node. Thermal characterization shows that for a 165K change in temperature, the Sub-threshold Slope (SS) and threshold voltage vary by 69 % and ∼70 mV, respectively. At room temperature, a single gate contacted n-FinFET RF device exhibits a cutoff and maximum oscillation frequency of ∼100 GHz and ∼170 GHz, respectively. Analog and RF Figures of Merit (FoMs) for 5 nm technology at a device level and their temperature sensitivity are also reported. The industry standard BSIM-CMG model is modified to capture the impact of self-heating (SH) and parasitics. The SH model is based on measured data, and the modeling approach renders it independent of other model parameters. To the authors' knowledge, an iteration free approach to develop a model-card for RF applications is explained for the very first time. Excellent agreement between the measured data and the model indicates that our methodology is accurate and can be used for faster PDK development.
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.
