Abstract
Vertically stacked, buried power rails are electrically connected to wrap-around contacts or other electrically conductive liners on transistor source/drain regions. The buried power rails are electrically isolated from each other by an electrical insulator. Wrap-around contacts can be electrically connected to different ones of the vertically stacked, buried power rails or to the same buried power rail.
