Abstract
The embodiments of the invention provide a device, method, etc. for a dual stress STI. A semiconductor device is provided having a substrate with a first transistor region and a second transistor region different than the first transistor region. The first transistor region includes a PFET; and, the second transistor region includes an NFET. Further, STI regions are provided in the substrate adjacent sides of and positioned between the first transistor region and the second transistor region, wherein the STI regions each include a compressive region, a compressive liner, a tensile region, and a tensile liner.
