Homebrew NMOS Transistor Step by Step - So Easy Even Jeri Can Do It

Jeri shows step by step how to make a transistor and at home with a kiln, Whink Rust and Stain remover, Emulsitone spin on dopant, ebay wafers and vinyl stickers.

Did you also make a PMOS transistor?

[jeriellsworth]

I have. It takes longer.

[supergenius1994]

where do you get the starting wafer?

[jeriellsworth]

Ebay and an other companies that offer prime wafers. Very easy to find.

[supergenius1994]

I'm sorry, but I can't find anything at all.

[jeriellsworth]

They will show up on ebay. Keep an eye open for silicon wafer.  There are companies that sell directly too.

You make homebrewed transistors? IMHO, you are officially the coolest woman alive. :D

[jeriellsworth]

@ITGuru0111 Dust is not a huge problem when the transistors are as big your thumbnail.

[Sean Murphy]

Just started watching another of your videos on this. I was right that the substrate needed to be p-doped, but I didn't know that the wafers came like that.

[Sean Murphy]

Don't you need the substrate slightly p-doped?

you would LOVE to work at ASML. have a whole factory and lab at your disposal.

worked there my selves for years at E-dev. the dumpster was a gold mine at times for getting nice rare treats :)

Sorry to tell you I made my first transistor out of a strip of copper oxide and with that I changed my relay computers into transistorized ones running MS-DOS thx again your talented like evan duffy

How is it so amazing? I have taught myself everything I know about electronics, assembly language (z80, 6502, 65816, 680x0, 80x86, ARM, PDP, PDP-11, and a couple homebrews), Physics, and mathematics by self study and experimentation. Further I was at a disadvantage as I began studying these things when I was 8 years old and did not enter into university level studies until I was 11 years old.

As to this method of making NMOS transistors, it was fairly common in the early days of FETs.

So I've been obsessed with a homemade relay based computer, .... I've changed my mind - I want to make a homemade transistor based computer ;)

[silectronics]

you are the best girl....you keep making those wafers and i'll keep designing stuff with them....what a cool team we would make.........i have always wondered how bismuth could be used as a junction material given the weird properties it has with magnetic fields  and if such a type transistor could be made.....would the transistor behave......certainly laws of physics would no longer apply.......what do you think?........

[pedobear123]

are you a wizard

[vivid554]

Do you think you could develop the materials for a 3D printer to print them?
