Love this stuff.

Followed a couple of links and ended up on his brother's page, reading about another example of the anti-immigrant insanity that's taken hold of this country: https://adam.zeloof.xyz/2025/04/01/karim/ . So sad.

oh man, I remember hearing about this back then and I got excited that there had been an update. From what I hear he’s gone off to college now but will hopefully be back to cooking up semiconductors once he graduates

He founded a company with Jim Keller called Atomic Semi since then.

Awesome! I wouldn't have thought that it is possible to make ICs in a garage. Of course it requires a lot of knowledge, etc. But still, not a multi-billion dollar clean room with specialist equipment.

Replicating late 70s chip fab in one's parents' garage. Incredible honestly, given that the microprocessor is probably the most complex human invention.

The timing of this share is crazy, since I was just looking around a few days ago to see if there were any guides or even kits for doing photolithography at home. It's part of my mission to demystify modern technology for my kids. I couldn't find anything, so this is excellent to see. Far too complex for my kids ages, but it might be cool to replicate at least part of this amazing project when they're older.

This is impressive work. Every time I see hobbyist-scale semiconductor projects, it reminds me how much innovation still happens outside big labs. Curious how far this approach can scale.
