Patent ID: 11233054

Abstract:
A semiconductor structure and a method for forming the semiconductor structure are provided. The semiconductor structure includes a substrate, which includes a first region, a second region, and a third region. The semiconductor structure also includes a first fin, a second fin, and a third fin formed on the first, second, and third regions, respectively. Moreover, the semiconductor structure includes an isolation layer formed on the substrate, and a portion of sidewall surface of each of the first, second, and third fins. In addition, the semiconductor structure includes a first epitaxial layer, a second epitaxial layer, and a third epitaxial layer formed on the first, second, and third fins, respectively. Two sides of the third epitaxial layer are in contact with the first epitaxial layer and the second epitaxial layer, respectively. Further, the semiconductor structure includes a conductive structure formed on the first, second, and third epitaxial layers.
