Abstract
A method includes forming a transistor on a front-side of a substrate, the transistor comprising a channel region, a gate structure surrounding the channel region, and source/drain regions on opposite sides of the gate structure; forming a front-side contact on a first one of the source/drain regions of the transistor; forming a back-side contact on a second one of the source/drain regions of the transistor; forming a back-side capacitor on the back-side contact.
