Abstract

Methods and apparatus are disclosed for selectively inducing stress in a semiconductor device, wherein a first region of a substrate is implanted so as to induce stress in a second region. An electrical device is formed at least partially in the second region, wherein the induced stress therein may improve one or more operational characteristics of the device, such as channel region carrier mobility.
