Abstract
A fin field effect transistor (FinFET) device structure and method for forming FinFET device structure are provided. The FinFET structure includes a substrate and an isolation structure formed on the substrate. The FinFET structure also includes a fin structure extending above the substrate, and the fin structure is embedded in the isolation structure. The FinFET structure further includes an epitaxial structure formed on the fin structure, the epitaxial structure has a pentagon-like shape, and an interface between the epitaxial structure and the fin structure is lower than a top surface of the isolation structure.
