    Abstract: A structure of semiconductor device is provided, including a substrate. First and second trench isolations are disposed in the substrate. A height of a portion of the substrate is between a top and a bottom of the first and second trench isolations. A gate insulation layer is disposed on the portion of the substrate between the first and second trench isolations. A first germanium (Ge) doped layer region is disposed in the portion of the substrate just under the gate insulation layer. A second Ge doped layer region is in the portion of the substrate, overlapping with the first Ge doped layer region to form a Ge gradient from high to low along a depth direction under the gate insulation layer. A fluorine (F) doped layer region is in the portion of the substrate, lower than and overlapping with the first germanium doped layer region.

    Abstract: A manufacturing method of a semiconductor device includes the following steps. An opening is formed penetrating a dielectric layer on a semiconductor substrate. A stacked structure is formed on the dielectric layer. The stacked structure includes a first semiconductor layer partly formed in the opening and partly formed on the dielectric layer, a sacrificial layer formed on the first semiconductor layer, and a second semiconductor layer formed on the sacrificial layer. A patterning process is performed for forming a fin-shaped structure including the first semiconductor layer, the sacrificial layer, and the second semiconductor layer. An etching process is performed to remove the sacrificial layer in the fin-shaped structure. The first semiconductor layer in the fin-shaped structure is etched to become a first semiconductor wire by the etching process. The second semiconductor layer in the fin-shaped structure is etched to become a second semiconductor wire by the etching process.

    Abstract: A manufacturing method of an epitaxial fin-shaped structure includes the following steps. A substrate is provided. A recess is formed in the substrate. An epitaxial layer is formed on the substrate. The epitaxial layer is partly formed in the recess and partly formed outside the recess. The epitaxial layer has a dent formed on the top surface of the epitaxial layer, and the dent is formed corresponding to the recess in a thickness direction of the substrate. A nitride layer is conformally formed on the epitaxial layer. An oxide layer is formed on the nitride layer. A first planarization process is performed to remove a part of the oxide layer, and the first planarization process is stopped on the nitride layer. The epitaxial layer in the recess is patterned for forming at least one epitaxial fin-shaped structure.
