Claim 10:
11. A semiconductor integrated circuit device including a standard cell, the standard cell comprising:
a first power supply line formed in a buried wiring layer, extending in a first direction and supplying a first power supply voltage;
a second power supply line formed in the buried wiring layer, extending in the first direction and supplying the first power supply voltage;
a third power supply line formed in the buried wiring layer, extending in the first direction between the first power supply line and the second power supply line 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 lying between the first power supply line and the second power supply line as viewed in plan;
a second transistor that is a three-dimensional transistor of a second conductivity type, formed above the first transistor in a depth direction, lying between the first power supply line and the second power supply line as viewed in plan;
a first local interconnect formed above the buried wiring layer in the depth direction and connected to a first terminal that is to be a source or drain of the first transistor;
a second local interconnect formed above the buried wiring layer in the depth direction and connected to a second terminal that is to be a source or drain of the second transistor;
a first contact formed at a position where the first power supply line and the first local interconnect overlap each other as viewed in plan, for connecting the first power supply line and the first local interconnect; and
a second contact formed at a position where the third power supply line and the second local interconnect overlap each other as viewed in plan, for connecting the third power supply line and the second local interconnect,, wherein
the second contact is longer in the depth direction than the first contact and greater in size in planar view than the first contact.
