WebAug 2, 2024 · Buried power rail means that the spacing between the P and N transistors in a cell is getting closer than we can deal with, <30nm. For all sorts of reasons, we can't really have the track spacing in the middle of the cells be larger than elsewhere, unless it is a whole track which defeats the purpose of removing a track. WebBuried power rail (BPR) is a key scaling booster for CMOS extension beyond the 5 nm node. This paper demonstrates, for the first time, the integration of tungsten (W) BPR lines with Si finFETs. The characteristics of CMOS in close proximity to floating BPR are found to be similar to the characteristics of CMOS without BPR. Moreover, W-BPR interface with … epic knowledge
