Hybrid FinFET structure
A semiconductor device includes a first fin field effect transistor (FinFET) device, the first FinFET device including a plurality of fins formed in a substrate, an epitaxial layer of semiconductor material formed on the fins forming non-planar source/drain regions, and a first gate structure traversing across the plurality of fins. The semiconductor device includes a second FinFET device, the second FinFET device including a substantially planar fin formed in the substrate, an epitaxial layer of the semiconductor material formed on the substantially planar fin and forming substantially planar source/drain regions, and a second gate structure traversing across the substantially planar fin.
