    摘要: A method of forming CMOS transistor is disclosed. A CMOS transistor having a first active area and a second active area is provided. In order to maintain the concentration of the dopants in the second active area, according to the method of the present invention an ion implantation process is performed to form a lightly doped drain (LDD) in the second active area after an epitaxial layer is formed in the first active area. On the other hand, the ion implantation process is performed to form the respective LDD of the first active area and the second active area. After the epitaxial layer in the first active area is formed, another ion implantation process is performed to implant dopants into the LDD of the second active area again.

    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.

    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.
