    Abstract: A semiconductor device includes; a substrate including a first region and a second region, a first active pattern extending upward from the first region, a first superlattice pattern on the first active pattern, a first active fin centrally disposed on the first active pattern, a first gate electrode disposed on the first active fin, and first source/drain patterns disposed on opposing sides of the first active fin and on the first active pattern. The first superlattice pattern includes at least one first semiconductor layer and at least one first blocker-containing layer, and the first blocker-containing layer includes at least one of oxygen, carbon, fluorine and nitrogen.

    Abstract: The semiconductor device may include an active pattern provided on a substrate and a source/drain pattern on the active pattern. The source/drain pattern may include a bottom surface in contact with a top surface of the active pattern. The semiconductor device may further include a channel pattern connected to the source/drain pattern, a gate electrode extended to cross the channel pattern, and a fence insulating layer extended from a side surface of the active pattern to a lower side surface of the source/drain pattern. A pair of middle insulating patterns may be at both sides of the bottom surface of the source/drain pattern and between the active pattern and the source/drain pattern in contact with an inner side surface of the fence insulating layer.
