    Abstract: A method of fabricating a semiconductor device is provided. The method includes: forming mask patterns on a substrate, the mask patterns including a first mask fin pattern, a second mask fin pattern and a dummy mask pattern between the first mask fin pattern and the second mask fin pattern; forming a first fin pattern, a second fin pattern and a dummy fin pattern by etching the substrate using the mask patterns; and removing the dummy fin pattern, wherein the dummy mask pattern is wider than each of the first mask fin pattern and the second mask fin pattern.

    Abstract: A semiconductor device includes a back interlayer insulating film, a back wiring line disposed within the back interlayer insulating film, a fin-type pattern disposed on a first surface of the back wiring line, a source/drain pattern disposed on the fin-type pattern, and a back wiring contact connecting the back wiring line and source/drain pattern. A bottom surface of the source/drain pattern is connected to the fin-type pattern and faces the back wiring line. The back wiring contact includes a back contact barrier film, a back contact plug film, and a back ferroelectric material film. The back wiring contact includes a third surface facing the back wiring line. A vertical length from a second surface of the back wiring line to the third surface of the back wiring contact is less than a vertical length from the second surface to the bottom surface of the source/drain pattern.
