Abstract: A process for fabricating a fin-type field effect transistor (FinFET) structure is described. A semiconductor substrate is patterned to form a fin. A spacer is formed on the sidewall of the fin. A portion of the fin is removed, such that the spacer and the surface of the remaining fm together define a cavity. A piece of a semiconductor compound is formed from the cavity, wherein the upper portion of the piece of the semiconductor compound laterally extends over the spacer.

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.

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.
