    摘要: A complementary metal-oxide-semiconductor (CMOS) transistor comprising a substrate, a first conductive type MOS transistor, a second conductive type MOS transistor, a buffer layer, a first stress layer and a second stress layer is provided. The substrate has a device isolation structure therein that defines a first active area and a second active area. The first conductive type MOS transistor and the second conductive type MOS transistor are respectively disposed in the first active area and the second active area of the substrate. A first nitride spacer of the first conductive type MOS transistor has a thickness greater than that of a second nitride spacer of the second conductive type MOS transistor. The buffer layer is disposed on the first conductive type MOS transistor. The first stress layer is disposed on the buffer layer. The second stress layer is disposed on the second conductive type MOS transistor.

    摘要: A method of forming a semiconductor device. The method comprises steps of providing a substrate having a first transistor, a second transistor and non-salicide device formed thereon and the conductive type of the first transistor is different from that of the second transistor. A buffer layer is formed over the substrate and a tensile material layer is formed over the buffer layer. A portion of the tensile material layer over the second transistor is thinned and a spike annealing process is performed. The tensile material layer is removed to expose the buffer layer over the substrate and a patterned salicide blocking layer is formed over the non-salicide device. A salicide process is performed for forming a salicide layer on a portion of the first transistor and the second transistor.

    摘要: A method for fabricating a semiconductor device is provided. First, a substrate is provided, and a first-type MOS (metallic oxide semiconductor) transistor, an input/output (I/O) second-type MOS transistor, and a core second-type MOS transistor are formed on the substrate. Then, a first stress layer is formed to overlay the substrate, the first-type MOS transistor, the I/O second-type MOS transistor, and the core second-type MOS transistor. Then, at least the first stress layer on the core second-type MOS transistor is removed to reserve at least the first stress layer on the first-type MOS transistor. Finally, a second stress layer is formed on the core second-type MOS transistor.
