Abstract

In this paper we highlight the complementarities of process-induced stress and wafer level stress (sSOI). We first present a state of the art of the various strain engineering techniques used in production for both PMOS and NMOS devices and discuss their scalability for 45nm and 32 nm nodes using some mechanical modeling. In a second part, we explain how wafer level stress can be used together with process-induced stress to overcome these difficulties and insure further performance enhancement. We discuss some device data showing compatibility and additivity of process-induced and wafer level stress. Finally, we give an overview of further sSOI developments that will insure scalability beyond 32nm. copyright The Electrochemical Society.
