Abstract
A semiconductor device includes a frontside including first metal structures, transistors disposed between the frontside and a backside opposite the frontside, each transistor including a source/drain positioned within a stack of nanolayers, the stack of nanolayers forming a gate structure and a power circuit on the backside and connected to the transistors by backside contacts. A backside dielectric isolation has a horizontal portion along a backside of the gate structure and a vertical portion substantially perpendicular to the backside and self-aligned to selected source/drains to electrically isolate the power circuit from the transistors.
