This is all you need to build simple transistors and IC's at your home. This picture was taken at the Think conference by a good friend.

We spent the weekend making solar cells, single transitors(fets), pmos inverter(resistive load) and a full CMOS inverter.

To the left you can see the nitrogen gas bottle, some cassettes of wafers, toward the middle the linberg furnace and test equipment to the right.


Keep an eye out for more chip fab videos at

    I found it interesting that the biggest reaction I got was when I made solar cells. I guess this is a good indicator what is on peoples minds these days.

    that's quite a bit of progress since your talk a few years ago.

    That´s pretty interesting stuff. I also watched your lecture at metalabs, which is a nice introduction to the diy semiconductor home fabrication. As electronics technician you usually only got taught how those components work and schematically look, but not how the production process is carried out.

    Nice to see someone is actually doing it and making the knowledge available.

    diy components? how cool is THAT! ;)

    Very impressive.

    Wow! Came across this while googling for "home made transistors". That's an idea that's always fascinated me. Your setup is the most advanced I've ever seen.

    what would it take to make a processor?
    like Suns' Niagra

    Jeri--I'd love to see you come out with a book that teaches DIYs home fabrication techniques.
  • John Boxall 5y

    That is just awesome. Words cannot do you justice.

    I have always wanted to make a homemade integrated circuit, or better yet a cpu, it looks like
    I have found just the right search engine and search term to find some help.

    Hi Jeri,

    Wow !!!!!!!!!!!!!!

    Well I've always been a bit slow :)

    I haven't watched your videos yet, but what is the "ballpark" $$$ for all your stuff?

    And ..

    Have you played with 3d printing tech ?

    The little I know about either 3dprinting or chip manufacturing, leads me to think that 3dp might be cleaner, easier ??? (though AFAIK, 3dp is not anywhere close to I.C. fabrication capability yet.
