Claim 0:
1. An integrated circuit comprising:
a first-voltage power rail and a second-voltage power rail, each of the first-voltage and second-voltage power rails extending in a second direction that is perpendicular to a first direction, each of the first-voltage and second-voltage power rails being in a first connection layer;
a first-voltage underlayer power rail and a second-voltage underlayer power rail below the first connection layer, each of the first-voltage and second-voltage underlayer power rails extending in the first direction;
a first via-connector connecting the first-voltage power rail with the first-voltage underlayer power rail, and a second via-connector connecting the second-voltage power rail with the second-voltage underlayer power rail;
a first semiconductor structure having a source region of a first-type transistor therein conductively connected to the first-voltage underlayer power rail, the first semiconductor structure underneath the first connection layer;
a second semiconductor structure having a source region of a second-type transistor therein conductively connected to the second-voltage underlayer power rail, the second semiconductor structure underneath the first connection layer;
a first signal conducting line extending in the second direction and in the first connection layer;
a gate-conductor extending in the second direction, the gate-conductor intersects either the first semiconductor structure or the second semiconductor structure at a channel region; and
a gate via-connector directly connecting the gate-conductor with the first signal conducting line.
