  • Patent number: 9431239
    Abstract: A method for fabricating semiconductor device is disclosed. The method includes the steps of: providing a substrate; forming a doped region in the substrate; forming a thermal oxide layer on the substrate and the doped region; removing the thermal oxide layer to form a first recess; forming an epitaxial layer on the substrate and in the first recess; and forming a gate dielectric layer in the epitaxial layer.
    Type: Grant

  • Publication number: 20150104914
    Abstract: A semiconductor process is provided, including following steps. A polysilicon layer is formed on a substrate. The polysilicon layer is cryo-implanted with at least two of multiple species including a germanium species, a carbon species and a p- or n-type species, at a temperature ranging between ?40° C. and ?120° C. An asymmetric dual-side heating treatment is performed to the polysilicon layer, wherein a power for a front-side heating is different from a power for a backside heating.
