A semiconductor device includes a gate pattern formed over a semiconductor substrate, the substrate defining a cell region and a peripheral region. First and second contact plugs are formed in the cell region. Third and fourth contact plugs are formed in the peripheral region. A first separation structure is formed in the cell region and covers the first contact plug. A second separation structures are formed in the peripheral region and define first and second openings, the first opening exposing an upper portion of the third contact plug, the second opening exposing an upper portion of the fourth contact plug. First, second, and third metal wire sections are formed over the first, second, third, and fourth contact plugs. The first metal wire section is formed in the cell region and contacts the second contact plug. The second metal wire section is formed in the peripheral region and contacts the third contact plug. The third metal wire section is formed in the peripheral region and contacts the fourth contact plug. The first separation structure electrically isolates the first contact plug from the first metal section. |
