"Z1" - Homemade Silicon ICs / Computer Chips

you're looking at something so astonishing it almost contradicts everyday conceptions of reality it does the work of a room full of electrical circuits yet it uses almost no energy its predecessor cost over a million dollars and took up hundreds of square feet but it costs less than $10 and is smaller than your fingertip it's called a chip hi my name is Sam and in April of 2018 I released details on how I made my first integrated circuit at home I realized I never mentioned this on my youtube channel so here's a quick dive into making computer chips at home the chips have made her a simple differential amplifier containing six transistors on a 5 micron metal gate pima's process which is straight out of the early 1970s taking about two years to achieve this but those specs can be improved on quite a lot the FETs and diodes have really good characteristics and I've wired here as a ring oscillator in which three knock gates are chained together to blink an LED do this at home I've had to build and acquire quite a lot of specialized equipment this is a home-built lithography stepper that projects images in ultraviolet onto the chip from a DLP projector to expose photoresist and pattern of various layers with parts from eBay and donations I was able to build a high vacuum chambers for sputtering and thermal evaporation of metal layers onto the chip I also picked up this electron microscope which is not strictly necessary for making chips but makes things a lot easier it was a lot of fun to learn about this project was great because I got to learn so much about so many different fields this is a plasma sputtering system vacuum chamber that I built and number of other plasma cleaning and plasma etching experiments as well if you want to see more about this check out my website and YouTube channel also what to deal with a number of hazardous chemicals like hydrofluoric acid phosphoric acid sulfuric acid hydrochloric acid a number of others one of the steps involves a very high temperature furnace at about 1,200 degrees C for doping and the final step to put it all together is wire bond which I talked about in my last YouTube video and check that out and that's it thanks for watching my emails on my website so if you want to share any thoughts or ask some questions you can contact me there Thanks
