Backside Power Delivery and Bold Bets at Intel (2022)

> The net effect is a way to scale transistor size that doesn’t rely on EUV, and what’s more, this shrink will be the equivalent of 2 generations of EUV shrinkage.. That’s huge and now it’s pretty much the roadmap for future semiconductor scaling.

This is a significant point. The future of VLSI is likely not going to be just about shrinking transistors. We have to think about how feasible it is to fit so many transistors in such a small area, and all of the fundamental limitations that poses. It's possible that there will be an major secondary development pathway regarding how to provide power to transistors for future fabrication nodes. Backside power delivery may deliver as big if not bigger gains than simple shrinking of transistor sizes for the next few nodes.
