0.2V adiabatic NC-FinFET with 0.6mA/µm I<inf>ON</inf> and 0.1nA/µm I<inf>OFF</inf>

Abstract

We present for the first time a Negative Capacitance (NC) FinFET. Simulation shows 0.2V operation with 0.6mA/µm on-current and 100pA/µm leakage current. A simple model guides the optimization of the ferroelectric film and the FinFET in the NC-FinFET. Our finding that a weak ferroelectric material is preferable greatly increases the candidate material classes and we report the target properties to search for. Counterintuitively, the gate to S/D capacitance and a thicker EOT both reduce the required V <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">DD</inf> . NC-FinFET is good for high performance and very low power applications.
