An integrated circuit includes a first power rail, a second power rail, and a power tap cell. The first power rail is at a first side of the integrated circuit. The second power rail is at a second side of the integrated circuit. The first and second sides are on opposite sides of at least a complementary field effect transistor. The power tap cell is coupled to the first power rail and the second power rail and configured to provide power from the first power rail to the second power rail.

Integrated circuits and methods for power delivery

A semiconductor structure includes a first transistor having a first source/drain (S/D) feature and a first gate; a second transistor having a second S/D feature and a second gate; a multi-layer interconnection disposed over the first and the second transistors; a signal interconnection under the first and the second transistors; and a power rail under the signal interconnection and electrically isolated from the signal interconnection, wherein the signal interconnection electrically connects one of the first S/D feature and the first gate to one of the second S/D feature and the second gate.
