Abstract: Provided is a semiconductor device including a lower pattern layer including a first semiconductor material; a first conductivity-type doped pattern layer disposed on the lower pattern layer and including a semiconductor material doped with a first conductivity-type impurity; a source/drain pattern disposed on the first conductivity-type doped pattern layer and including a semiconductor material doped with a second conductivity-type impurity different from the first conductivity-type impurity; a channel pattern including semiconductor patterns connected between the source/drain patterns, stacked apart from each other, and including a second semiconductor material different from the first semiconductor material; and a gate pattern disposed on the first conductivity-type doped pattern layer and between the source/drain patterns, and surrounding the channel pattern.
