Abstract
A semiconductor device includes a semiconductor substrate, an active region on the semiconductor substrate and including a first semiconductor material, an isolation layer on the semiconductor substrate and a side surface of the active region, a first gate structure in a first gate trench crossing the active region, a second gate structure in a second gate trench in the isolation layer, the second gate structure being parallel to the first gate structure and adjacent to the active region, a semiconductor layer covering at least a part of the side surface of the active region, the semiconductor layer including a second semiconductor material different from the first semiconductor material, and at least a part of the semiconductor layer being between the active region and the second gate structure, and source/drain regions in the active region on opposite sides of the first gate trench.
