Abstract
A semiconductor device includes multiple transistors formed in a substrate, a frontside power rail disposed on a frontside of the substrate, and a backside power rail disposed on a backside of the substrate. The transistors form at least a first cell functioning under a first power supply voltage and a second cell functioning under a second power supply voltage that is different from the first power supply voltage. The frontside power rail provides the first power supply voltage to the first cell, and the backside power rail provides the second power supply voltage to the second cell.
