    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.

    摘要: A method of fabricating a complementary metal oxide semiconductor (CMOS) device is provided. A first conductive type MOS transistor including a source/drain region using a semiconductor compound as major material is formed in a first region of a substrate. A second conductive type MOS transistor is formed in a second region of the substrate. Next, a pre-amorphous implantation (PAI) process is performed to amorphize a gate conductive layer of the second conductive type MOS transistor. Thereafter, a stress-transfer-scheme (STS) is formed on the substrate in the second region to generate a stress in the gate conductive layer. Afterwards, a rapid thermal annealing (RTA) process is performed to activate the dopants in the source/drain region. Then, the STS is removed.

    摘要: A method of fabricating a semiconductor device is provided. A substrate is first provided, and than several IO devices and several core devices are formed on the substrate, wherein those IO devises include IO PMOS and IO NMOS, and those core devises include core PMOS and core NMOS. Thereafter, a buffer layer is formed on the substrate, and then the buffer layer except a surface of the IO PMOS is removed in order to reduce the negative bias temperature instability (NBTI) of the IO PMOS. Afterwards, a tensile contact etching stop layer (CESL) is formed on the IO NMOS and the core NMOS, and a compressive CESL is formed the core PMOS.
