Abstract
A semiconductor structure with buried power rails (BPRs) and a method of fabricating the same are disclosed, the BPRs are formed in a semiconductor substrate, and device structures are formed on the side of a second surface of the semiconductor substrate. Connections and a signal delivery network (SDN) layer are formed on side of the second surface, and a power delivery network (PDN) layer is then formed on the side of a first surface of the semiconductor substrate.
