Highly Manufacturable TiN Metal Gate Nanorod Transistors Realized on Silicon-On-ONO (SOONO) Substrate

Abstract

In this article, we proposed and successfully demonstrated 25 nm TiN metal gate nanorod transistors with laterally and vertically scaled actives without process burdens. They showed the excellent short channel effect immunity and high current drivability DIBLs are below 40 mV/V and subthreshold swings are nearly ideal values showing no temperature dependency. The driving currents of 1.4 mA/mum for nMOS and 1.0 mA/mum for pMOS are achieved at Ioff=100 nA/mum and VD =1.0 V. Thus, it is proven that laterally and vertically scaled nanorod transistors can be a promising solution for ultimate scaling
