Z2: Homemade Chips with About 1,000 Transistors

HN uses it as the go-to proof that small-scale, hobbyist chip fabrication is real, and as an entry point to the topic.

Sam Zeloof shows the upgraded second iteration of his homemade silicon integrated circuit fabrication process, producing chips with around a thousand transistors in his garage. It is a short overview of what the home fab can now do.
