ABSTRACT:
A semiconductor device includes first and second unit circuits. Each first unit circuit has first transistors connected in series, wherein each of the first transistors includes a first gate structure having a pitch. Each second unit circuit has second transistors connected in series, wherein each of the second transistors includes a second gate structure having the pitch. A third transistor and a fourth transistor electrically isolate each of the first and second unit circuits, respectively. An insulation layer covers the first through the fourth transistors. Plugs in the insulation layer are connected to a first gate structure, a second gate structure, a first source region, a first drain region, a second source region or a second drain region. A wiring is connected to the plugs.
