Abstract: A semiconductor device includes a substrate, a first active pattern disposed on the substrate, a second active pattern stacked on the first active pattern, a first gate structure extending to intersect the first active pattern and the second active pattern, a second gate structure spaced apart from the first gate structure and extending to intersect the first active pattern and the second active pattern, a first epitaxial pattern interposed between the first gate structure and the second gate structure, and connected to the first active pattern, a second epitaxial pattern interposed between the first gate structure and the second gate structure, and connected to the second active pattern, an insulating pattern interposed between the first epitaxial pattern and the second epitaxial pattern, and a semiconductor film interposed between the insulating pattern and the second epitaxial pattern, the semiconductor film extending along a top surface of the insulating pattern.
