Advanced CMOS reliability challenges

Abstract

This work reviews transistors of advanced CMOS process nodes from a reliability perspective and covers some of the important challenges and solutions. Physical mechanisms for various modes are investigated for 65nm to 22nm nodes with focus on disruptive changes such as HK/MG and Tri-gate/FinFET. The importance of modeling non-idealities and variation is also emphasized, and projections are made for scaling to sub-20nm with comparisons to existing research.
