A method for making a semiconductor structure that overcome the dual stress liner boundary problem, without significantly increasing the overall size of the integrated circuit, is provided. In accordance with embodiments of the present invention, the dual stress liner boundary or gap therebetween is forced to land on a neighboring dummy gate region. By forcing the dual stress liner boundary or gap between the liners to land on the dummy gate region, the large stresses associated with the dual stress liner boundary or gap are transferred to the dummy gate region, not the semiconductor substrate. Thus, the impact of the dual stress liner boundary on the nearest neighboring FET is reduced. Additionally, benefits of device variability and packing density are achieved utilizing the present invention.
