    • A complementary metal-oxide-semiconductor (CMOS) device comprising a substrate, a first type of metal-oxide-semiconductor (MOS) transistor, a second type of MOS transistor, an etching stop layer, a first stress layer and a second stress layer is provided. The substrate has a first active region and a second active region. The first active region is isolated from the second active region through an isolation structure. The first type of MOS transistor is disposed in the first active region of the substrate; the second type of MOS transistor is disposed in the second active region of the substrate. The etching stop layer covers conformably the first type of MOS transistor, the second type of MOS transistor and the isolation structure. The first stress layer is disposed on the etching stop layer in the first active region and the second stress layer is disposed on the etching stop layer in the second active region.
