Study of undoped channel FinFETs in active rail clamp ESD networks

In this paper we investigate state-of-the-art undoped channel FinFETs and FinDiodes with an emphasis on I/O and ESD applicability. Utilizing electrical characterization data, 3D TCAD, and a compact model, we demonstrate that FinFETs and FinDiodes exhibit a very appealing combination of high breakdown voltage and low Ioff for I/O and ESD protection circuit applications.
