Home Chip Fabrication in 66 Steps
Without further ado, I present the first home(garage)made lithographically-fabricated integrated circuit – the “Z1” PMOS dual differential amplifier chip. I say “lithographically-fabricated” becauseJeri Ellsworth made the first transistors and logic gates (meticulously hand wired with conductive epoxy) andshowedthe world that this is possible. Inspired by her work, I have demonstratedICsmade by a scalable, industry-standard, photolithographic process.
Needless to say, this is the logical step-up from my previous replication of Jeri’s FET fabrication work.
