    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 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.
