A semiconductor device may include a plurality of active patterns and a plurality of gate structure on a substrate, a first insulating interlayer covering the active patterns and the gate structures, a plurality of first contact plugs extending through the first insulating interlayer, a plurality of second contact plugs extending through the first insulating interlayer, and a first connecting pattern directly contacting a sidewall of at least one contact plug selected from the first and second contact plugs. Each of gate structures may include a gate insulation layer, a gate electrode and a capping pattern. Each of first contact plugs may contact the active patterns adjacent to the gate structure. Each of the second contact plugs may contact the gate electrode in the gate structures. An upper surface of the first connecting pattern may be substantially coplanar with upper surfaces of the first and second contact plugs.

Semiconductor devices and method of manufacturing the same

A semiconductor device includes a substrate including a first region and a second region, an active gate structure on the substrate in the first region, a dummy gate structure on the substrate in the second region, a source/drain on the substrate in the first region at each of opposite sides of the active gate structure, a plurality of first conductive contacts respectively connected to the active gate structure and the source/drain, a resistive structure on the dummy gate structure in the second region, a plurality of second conductive contacts respectively connected to the plurality of first conductive contacts and the resistive structure, and an etch stop layer between the dummy gate structure and the resistive structure. The etch stop layer includes a lower etch stop layer and an upper etch stop layer, which are formed of different materials.
