Abstract
Provided is a semiconductor device. The semiconductor device comprises a first transistor stacked above a second transistor. The semiconductor device further includes a frontside power rail that is electrically coupled to a source/drain epitaxy of the first transistor. The semiconductor device further includes a backside power rail that is electrically coupled to a source/drain epitaxy of the second transistor. The semiconductor device further includes a plurality of frontside signal lines. The plurality of signal lines includes a first frontside signal line that is electrically coupled to a source/drain epitaxy of the second transistor. The frontside signal line is connected to the source/drain epitaxy through a backside contact and an interlevel via.
