Abstract: A semiconductor device includes a substrate including an active region, a gate trench disposed in the substrate and crossing the active region; a gate dielectric layer disposed in the gate trench; a first gate electrode disposed on the gate dielectric layer and including center and edge portions; a second gate electrode disposed on the first gate electrode; a gate capping insulating layer disposed on the second gate electrode and filling the gate trench; and first and second impurity regions disposed in the substrate opposite to each other with respect to the gate trench. A top surface of each of the center and edge portions contacts a bottom surface of the second gate electrode. The top surface of the second gate electrode is concave. The bottom surface of the gate capping insulating layer is convex, and a side surface of the gate capping insulating layer contacts the gate dielectric layer.
