    摘要: A method for fabricating a metal oxide semiconductor (MOS) device is described, including following steps. Two recesses are formed in a substrate. A first epitaxy growth process is performed, so as to form a first semiconductor compound layer in each of the recesses. A second epitaxy growth process is performed with an epitaxial temperature lower than 700° C., so as to form a cap layer on each of the first semiconductor compound layers. Each of the cap layers includes a second semiconductor compound layer protruding from a surface of the substrate. The first and the second semiconductor compound layers are composed of a first Group IV element and a second Group IV element, wherein the second Group IV element is a nonsilicon element. The content of the second Group IV element in the second semiconductor compound layers is less than that in the first semiconductor compound layers.

    摘要: First, a substrate with a recess is provided in a semiconductor process. Second, an embedded SiGe layer is formed in the substrate. The embedded SiGe layer includes an epitaxial SiGe material which fills up the recess. Then, a pre-amorphization implant (PAI) procedure is carried out on the embedded SiGe layer to form an amorphous region. Next, a source/drain implanting procedure is carried out on the embedded SiGe layer to form a source doping region and a drain doping region. Later, a source/drain annealing procedure is carried out to form a source and a drain in the substrate. At least one of the pre-amorphization implant procedure and the source/drain implanting procedure is carried out in a cryogenic procedure below −30° C.
