    Abstract: A semiconductor device includes device isolation layer on a substrate to define an active region, a first gate electrode on the active region extending in a first direction parallel to a top surface of the substrate, a second gate electrode on the device isolation layer and spaced apart from the first gate electrode in the first direction, a gate spacer between the first gate electrode and the second gate electrode, and source/drain regions in the active region at opposite sides of the first gate electrode. The source/drain regions are spaced apart from each other in a second direction that is parallel to the top surface of the substrate and crossing the first direction, and, when viewed in a plan view, the first gate electrode is spaced apart from a boundary between the active region and the device isolation layer.
