  • Publication number: 20100148228
    Abstract: A semiconductor device includes a gate formed on a semiconductor substrate. A first junction region is formed on a first side of the gate and a second junction region formed on a second side of the gate. A bit line is formed over the gate to be electrically coupled with the first junction region. A first metal plug is formed electrically coupling the second junction region. A bit line contact plug is provided between the first junction region and the bit line, and electrically couples the first junction region and the bit line. A second metal plug is formed over the first metal plug and electrically couples the first metal plug. The junction region of a gate in a core or peripheral region is connected to the metal line using a metal plug so that bit lines formed in the core and peripheral area can have a pattern similar to that formed in a cell region.
