Claim Text:
1. An integrated circuit (IC), comprising: a substrate, wherein the substrate includes functional devices formed therein; a dummy diffusion region formed within the substrate, wherein the dummy diffusion region is one of a p-type or a n-type; a strain-inducing composite embedded into the dummy diffusion region; and a strain-inducing composite disposed on top of the dummy diffusion region, wherein a crystal orientation of the strain inducing composite embedded into the dummy diffusion region is substantially identical to a crystal orientation of the strain-inducing composite disposed on to of the dummy diffusion region, and wherein the crystal orientation of the strain inducing composite embedded into the dummy diffusion region and the crystal orientation of the strain-inducing composite disposed on top of the dummy diffusion region are substantially identical to a crystal orientation of the substrate.
