    Abstract: A semiconductor device includes first and second gate structures, first and second contact plug structures and a first wiring on a substrate. The first and second source/drain layers are formed on portions of the substrate adjacent to the first and second gate structures, respectively. The first and second contact plug structures are formed on the first and second source/drain layers, respectively. The first wiring contacts an upper surface of the first gate structure. The first gate structure includes a first gate electrode and a first gate insulation pattern on a lower surface and a sidewall of the first gate electrode. The second gate structure includes a second gate electrode and a second gate insulation pattern on a lower surface and a sidewall of the second gate electrode. The upper surface of the second gate electrode is lower than an upper surface of the first gate electrode.

    Abstract: A semiconductor device includes an active region extending on a substrate in a first direction, a gate structure including a gate electrode extending on the substrate in a second direction and traversing the active region, a spacer structure extending on opposing sidewalls of the gate electrode in the second direction, and a capping layer on the gate electrode and the spacer structure, a source/drain region on the active region adjacent the gate structure, and a first contact plug connected to the source/drain region and a second contact plug connected to the gate structure. The capping layer includes a lower capping layer and an upper capping layer on the lower capping layer, and the second contact plug penetrates through the capping layer, is connected to the gate electrode and includes a convex sidewall penetrating into the upper capping layer.
