    摘要： A Multi-Gate Field-Effect Transistor includes a fin-shaped structure, a gate structure, at least an epitaxial structure and a gradient cap layer. The fin-shaped structure is located on a substrate. The gate structure is disposed across a part of the fin-shaped structure and the substrate. The epitaxial structure is located on the fin-shaped structure beside the gate structure. The gradient cap layer is located on each of the epitaxial structures. The gradient cap layer is a compound semiconductor, and the concentration of one of the ingredients of the compound semiconductor has a gradient distribution decreasing from bottom to top. Moreover, the present invention also provides a Multi-Gate Field-Effect Transistor process forming said Multi-Gate Field-Effect Transistor.

    摘要： A semiconductor process includes the following steps. A substrate is provided. At least a fin-shaped structure is formed on the substrate. An oxide layer is formed on the substrate without the fin-shaped structure being formed thereon. A gate is formed to cover a part of the oxide layer and a part of the fin-shaped structure. An etching process is performed to etch a part of the fin-shaped structure beside the gate, therefore at least a recess is formed in the fin-shaped structure. An epitaxial process is performed to form an epitaxial layer in the recess, wherein the epitaxial layer has a hexagon-shaped profile structure.
