Abstract
An integrated circuit includes a first and a second power rail on a back-side of a wafer and configured to supply a first voltage, a footer circuit coupled to the first and the second power rail, and configured to receive a second supply voltage, and to supply the first voltage to the first and the second power rail in response to a control signal, a third power rail on the back-side of the wafer, and configured to supply a third voltage, a fourth power rail on a front-side of the wafer and a fifth power rail on the back-side of the wafer. The fourth power rail and the fifth power rail are configured to supply the second voltage to the footer circuit. The fourth power rail includes a first set of conductors, each conductor of the first set of conductors is separated from one another in the first direction.
