Abstract

Further improvement of FinFET has been demonstrated in the extension of the Moore's Law toward N3 technology and beyond. In the width direction, the approach is to use air-trench-isolation (ATI) between fins such that inter-fin spaces with air-gap in the active region become scalable. Along the channel direction, air-spacer between gate and S/D was adopted to reduce the parasitic capacitance. The scalable ATI FinFET exhibits better DC and RF performance as a result of huge increase of Ion and the reduction of Cgd. As a benchmark, in comparison to the conventional FinFET, we provide a guideline on designing much better improvement of the FinFET towards N3 technology node.
