    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: A semiconductor device includes a substrate including a peripheral region, a first active pattern on the peripheral region, the first active pattern having an upper portion including first semiconductor patterns and second semiconductor patterns, which are alternately stacked, a first gate electrode intersecting the first active pattern, a pair of first source/drain patterns provided at both sides of the first gate electrode, respectively, a first capping layer on the first active pattern, a second capping layer on the first capping layer, and a first gate insulating layer between the second capping layer and the first gate electrode. The first capping layer is between a sidewall of the first active pattern and the second capping layer. A concentration of germanium (Ge) of the first capping layer is greater than a concentration of germanium of the second capping layer.
