One embodiment exemplarily described herein can be generally characterized as a semiconductor device that includes a lower level device layer located over a semiconductor substrate, an interlayer insulating film located over the lower level device layer and an upper level device layer located over the interlayer insulating film. The lower level device layer may include a plurality of devices formed in the substrate. The upper level device layer may include a plurality of semiconductor patterns and at least one device formed in each of the plurality of semiconductor patterns. The plurality of semiconductor patterns may be electrically isolated from each other. Each of the plurality of semiconductor patterns may include at least one active portion and at least one body contact portion electrically connected to the at least one active portion.
