Patent ID: 11881455
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 7:
8. A semiconductor architecture comprising:
a carrier substrate;
a first semiconductor device provided on a first surface of the carrier substrate, the first semiconductor device being configured to route signals;
a second semiconductor device provided on a second surface of the carrier substrate opposite to the first surface of the carrier substrate, the second semiconductor device being configured to deliver power;
a buried power rail (BPR) included inside of the carrier substrate and extending from the first surface of the carrier substrate to the second surface of the carrier substrate,
wherein the BPR comprises a first BPR portion and a second BPR portion,
wherein a width of the first BPR portion is different from a width of the second BPR portion,
wherein the first BPR portion extends from the first surface of the carrier substrate and the second BPR portion extends from the second surface of the carrier substrate, and
wherein the first BPR portion and the second BPR portion are integrally formed.
