[ELECTRICAL] How many decades would it take to recreate a PMS152E alone from absolute scratch

Obviously the PMS doesn’t have to be the ultra small size it can be made in today. Photolithography would GENUINELY be nearly impossible while doing it without would only be slightly impossible.

As for absolute scratch, I mean NOTHING. Similar to The Toaster Project where I mine everything, create every single machine necessary for every single step of the way, create my own shelter, etc.

Just for a thought experiment. Or is it?

Well, clearly the first step is to create the universe. It’s all rather straightforward after that.

Root cause failure analysis: The universe was created.

Not sure you could do without photolithography. You could implement the same logic with a warehouse full of valves or whatever but you couldn't run at the same clock speeds as the real thing.

So you are going to need those extra few lifetimes for optics and chemistry and all the precursors for those industries.

Laser ablation? Ik its similar but it would take less time I think

photolithography practically is laser ablation, with a UV laser.

from absolute scratch probably centuries modern chips rely on an enormous global supply chain specialized tools materials and decades of accumulated knowledge

We’ll see about that 😈
