Abstract
We develop, for the first time, a compact and scalable model to account for the poly-space effects (PSEs) in uniaxially-strained Etch Stop Layer (ESL) stressors. The model is based on 2-dimensional (2D) finite element (FEM) stress simulations and 4-point bending characterization of Silicon, and agrees well with measured data. The impact of PSEs on circuit performance is also discussed.
