Original Abstract Submitted
a semiconductor device includes a fin-type active region that extends in length in a first horizontal direction on a substrate, a horizontal semiconductor layer on the fin-type active region, a seed layer on the fin-type active region and in contact with the horizontal semiconductor layer, a gate line that surrounds the horizontal semiconductor layer and the seed layer, on the fin-type active region, and that extends in length in a second horizontal direction that intersects the first horizontal direction, and a pair of vertical semiconductor layers respectively on first and second sides of the horizontal semiconductor layer in the first horizontal direction, on the fin-type active region, with the horizontal semiconductor layer therebetween, wherein an inner wall of each of the first and second vertical semiconductor layers contacts the horizontal semiconductor layer, and upper or lower surfaces of the vertical semiconductor layers contact the seed layer.
