Abstract
Embodiments disclosed herein describe a semiconductor structure. The semiconductor structure may include a device region with a first source/drain (S/D) and a second S/D. The semiconductor structure may also include a buried power rail (BPR) under the device region. A critical dimension of the BPR may be larger than a distance between the first S/D and the second S/D. The semiconductor structure may also include a via-contact-to-buried power rail (VBPR) between the BPR and the S/D.
