A method for fabricating a semiconductor device is disclosed. A substrate having thereon at least one metal-oxide-semiconductor (MOS) transistor is provided. A stress memorization technique (SMT) process is performed. The SMT process includes steps of depositing an SMT film covering the at least one MOS transistor on the substrate, and subjecting the SMT film to a thermal process. A lithographic process and an etching process are performed to form a patterned SMT film. A silicide layer is formed on the MOS transistor. The patterned SMT film acts as a salicide block layer when forming the silicide layer.
