Abstract:
1. A semiconductor device comprising: a substrate; first and second electrodes formed on the substrate arranged in a first direction, the first and second electrodes being included in a first cell transistor; a first contact plug having bottom and top surfaces, the bottom surface thereof being in contact with the first electrode; a second contact plug having bottom, first side and top surfaces, the bottom surface thereof being in contact with the second electrode; a first insulation film formed on the top surfaces of the first and second contact plugs; a bit line formed on the first insulation film, the bit line extending in the first direction; a bit line contact plug formed through the first insulation film so as to connect the bit line and the top surface of the first contact plug; a first cell capacitor including a first lower electrode, the first lower electrode and the bit line being arranged in a second direction different from the first direction; a second insulation film arranged between the bit line and the first lower electrode so as to insulate from each other; and a first contact conductor connecting the first lower electrode to the first side surface of the second contact plug.
