    Abstract: A semiconductor device includes a fin structure, an isolation structure, a gate structure and an epitaxial structure. The fin structure protrudes from the surface of the substrate and includes a top surface and two sidewalls. The isolation structure surrounds the fin structure. The gate structure overlays the top surface and the two sidewalls of a portion of the fin structure, and covers a portion of the isolation structure. The isolation structure under the gate structure has a first top surface, and the isolation structure at two sides of the gate structure has a second top surface. The first top surface is higher than the second top surface. The epitaxial layer is disposed at one side of the gate structure and is in direct contact with the fin structure.

    Abstract: A fabrication method of a semiconductor structure includes the following steps. First of all, a gate structure is provided on a substrate, and a first material layer is formed on the substrate and the gate structure. Next, boron dopant is implanted to the substrate, at two sides of the gate structure, to form a first doped region, and P type conductive dopant is implanted to the substrate, at the two sides of the gate structure, to form a second doped region. As following, a second material layer is formed on the first material layer. Finally, the second material layer, the first material layer and the substrate at the two sides of the gate structure are etched sequentially, and a recess is formed in the substrate, at the two sides of the gate structure, wherein the recess is positioned within the first doped region.

    Abstract: A semiconductor process includes the following steps. A substrate is provided. At least a fin-shaped structure is formed on the substrate and a gate structure partially overlapping the fin-shaped structure is formed. Subsequently, a dielectric layer is blanketly formed on the substrate, and a part of the dielectric layer is removed to form a first spacer on the fin-shaped structure and a second spacer besides the fin-shaped structure. Furthermore, the second spacer and a part of the fin-shaped structure are removed to form at least a recess at a side of the gate structure, and an epitaxial layer is formed in the recess.
