WebBuried power rail (BPR) is a key scaling booster to extend the CMOS technology roadmap beyond the 3 nm node. The process flow to co-integrate BPR within front-end-of-line, and Via-to-BPR (VBPR) within the middle-of-line needs to be defined. Secondly, BPR and VBPR metals need to be benchmarked based on their electrical/reliability performance. WebThe first integrated circuit die includes a first set of contacts on a bottom surface, a buried power rail (BPR), and a plurality of through-silicon vias (TSV) for connecting the BPR to the first set of contacts. The interposer includes a second set of contacts and a power delivery network (PDN).
