Classification: CPC H | IPC H

Claim 10:
11. A circuit structure, comprising:
a substrate;
a first transistor stack over the substrate, the first transistor stack comprising:
a first transistor, over the substrate, wherein the first transistor is a first conductivity type; and
a second transistor, above the first transistor, wherein the second transistor is a second conductivity type different from the first conductivity type;

a plurality of first conductive lines disposed in a first metal layer above the first transistor stack, the plurality of first conductive lines electrically connected to the first transistor stack; and
a plurality of second conductive lines in a second metal layer below the substrate and underneath the first transistor stack, the plurality of second conductive lines electrically connected to the first transistor stack,
wherein the plurality of first conductive lines are configured asymmetrically with respect to the plurality of second conductive lines.
