Intel's 14A Magic Bullet: Directed Self-Assembly (DSA)

After reading everything intel is up to, they are a risky long bet but if they hit half their marks it's going to pay off in a major way.

All of this is at the fringes of my understanding but what I do want to know is if intel is sticking with the single shot EUV so they have higher accuracy to do a 2nd shot on the back side of the wafer. This: https://spectrum.ieee.org/backside-power-delivery
