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 comprises a PFET; and, the second transistor region comprises 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 comprise a compressive region, a compressive liner, a tensile region, and a tensile liner.
