    摘要: An integrated circuit and an improved method for manufacturing a semiconductor using a stress proximity technique process are provided to reduce a compressive force of one or more NFET(N-type Field-Effect-Transistor) devices by protecting one or more NFET devices when a compressive stress liner is activated. At least one PFET(P-type Field-Effect-Transistor) device(104) includes first sidewall spacers(115A,115B) on at least one side of a first gate electrode(120). At least one NFET device(102) includes first sidewall spacers(114A,114B) formed on at least one side of a second gate electrode(112) and second spacers(116A,116B). Plural NFET and PFET devices are formed on a semiconductor substrate(108). A compressive stress layer covers at least one NFET and PFET devices and includes a nitride layer liner. Relaxation species are implanted into the compressive stress layer covering at least one NFET device to relax compressive stress on at least one NFET device. The relaxation species are not implanted into the compressive stress layer covering at least one PFET device.
