Claim 17:
18. A semiconductor integrated circuit device including a first standard cell and a second standard cell that is a capacitance cell, the first standard cell comprising:
a first power supply line extending in a first direction and supplying a first power supply voltage;
a second power supply line extending in the first direction and supplying a second power supply voltage different from the first power supply voltage;
a first transistor that is a three-dimensional transistor of a first conductivity type;
a second transistor that is a three-dimensional transistor of a second conductivity type, formed above the first transistor in a depth direction;
a first local interconnect connected with a source or drain of the first transistor, extending in a second direction perpendicular to the first direction as viewed in plan;
a second local interconnect connected with a source or drain of the second transistor, extending in the second direction as viewed in plan; and
a first gate interconnect that is to be a common gate of the first and second transistors, extending in the second direction as viewed in plan,
the second standard cell comprising:
a second gate interconnect formed on a level with the first gate interconnect in the depth direction;
a third local interconnect formed on a level with the first local interconnect in the depth direction; and
a fourth local interconnect formed on a level with the second local interconnect in the depth direction,
wherein
the second gate interconnect is electrically connected with one of the first and second power supply lines, and the third and fourth local interconnects are electrically connected with the other of the first and second power supply lines, and
the third and fourth local interconnects overlap each other as viewed in plan and are adjacent to the second gate interconnect as viewed in plan.
