Home Chip Lab
Home(garage)made lithographically-fabricated integrated circuit – the “Z1” PMOS dual differential amplifier chip. “Lithographically-fabricated” because Jeri Ellsworth made the first transistors and logic gates (meticulously hand wired with conductive epoxy) and showed the world that this is possible.

Laser Doping His Way To Homemade Silicon Chips
https://hackaday.com/2021/12/28/laser-doping-his-way-to-homemade-silicon-chips/
It’s a pity that more electronics enthusiasts haven’t taken the hobby to its ultimate level: making your own semiconductors. There are plenty of good reasons for that: chief among them is the huge expense involved in obtaining the necessary equipment. But for the sufficiently clever, there are ways around that.
[Zachary Tong] is dipping his toes into the DIY semiconductor world, and further to the goal of keeping costs to a hobbyist scale, is experimenting with laser doping of silicon. Doping is the process of adding impurities to silicon wafers in a controlled manner to alter the electrical properties of the semiconductor. [Zach]’s doping method is a more localized version of the simple thermal diffusion method, which drives a dopant like phosphorus into silicon using high temperatures, but instead of using a tube furnace, he’s using a fiber laser.

Old Printer Becomes Direct Laser Lithography Machine
https://hackaday.com/2022/03/22/old-printer-becomes-direct-laser-lithography-machine/
What does it take to make your own integrated circuits at home? It’s a question that relatively few intrepid hackers have tried to answer, and the answer is usually something along the lines of “a lot of second-hand equipment.” But it doesn’t all have to be cast-offs from a semiconductor fab, as [Zachary Tong] shows us with his homebrew direct laser lithography setup.
This machine makes patterns smaller than a human hair.

Student Competition Badge Bears Custom Silicon
https://hackaday.com/2022/08/09/student-competition-badge-bears-custom-silicon/
Daniel Valuch] shared a fun and record-setting conference badge story (Slovak, translated) with us. He was one of the organizers for the “ZENIT in electronics” event, which is an annual Slovakian national competition for students. During the competition, students are assigned a letter+number code for the purpose of result submission anonymity, and organizers are always on the lookout for a fun way to assign these codes – this time, they did it with custom silicon!
t just so happened that [Peter], one of [Daniel]’s colleagues, was at the time working for onsemi who were doing a tapeout and had some free space on their test chips. Of course, they didn’t have to think twice. When it was a student’s turn to draw their identification number, instead of a slip of paper, they received a SOIC-16 package with custom silicon bonded to it. Then, they had to solder it to their competition badge – which was, of course, a PCB. Each chip was individually laser-trimmed to contain the student’s number, and that number could then be decoded using a multimeter – or a reasonably sharp eye.
