Upgraded Homemade Silicon IC Fab Process

linux users when they understand that their cpu is prebuilt

[AppliedScience]

Wow! You could make videos about all the details, and we'd watch every minute :)

[smartereveryday]

This is amazing. How do you repeatably index the projection?

[Arrogan]

Dude. You just brought the computer industry back into the garage... ;) Seriously very cool.
With the latest 2/3nm processes being so out of reach of the average amateur geek, it is brilliant to be able to go back to basics again. And I love that you are showing everything, it is so much more interesting to actually see the process being done physically, seeing the etching process, washing, layering, etc.

I'm extremely surprised how not only he knows how to make the 2nd gen chip at home by himself, but what's even more impressive is that he explained it all basically in under 6 minutes only.

"Are you kids smoking reefer in the garage?" "No Mom, we are baking a phosphorous dopant at very high temperatures!"

[gregeoryl]

Incredible!
I've been in electronics for 40 years and never thought home built chips were possible.

[TP-nhoi]

You really know your stuff. I work on silicon diode radiation detectors which are quite easily ruined by any contamination or slightly wrong process conditions. Getting these mosfets to work in a garage is really impressive, especially with only one guy doing it!

Btw, we also have the 4145A semiconductor analyzer in everyday use, old but gold :D

Someone : " Can you build a computer for me?"
Sam :" Sure I can"
Someone :" wait why don't we go into the computer store?"
Sam : "You said you want me to build a computer"

As someone working in a large semiconductor fab it is surreal to see the work that we do carried out (albeit on a much smaller scale and much larger scale, if you catch my meaning) by one person in his garage. This is impressive as hell.

[Slarti]

This is fantastic because so much of technological advancement is about building machines that then build smaller machines recursively - so being able to build a chip from scratch is a real talent and excellent for humanity too.
You never know, you may discover something that was missed in the early development of chips that proves invaluable to modern chips.
Great work!

[shamon]

What happened to you ? What are you doing today ?

[network]

Almost 20 years of chip design and this is one the coolest things I've seen so far.

[maidpretty]

2025, Sam: Oh, I finally made it to 5nm.
Intel: here's our new process.

[steventaylor]

Dude, that's an insane level of focus and commitment. Super, SUPER, impressive.

[Electro]

Darn! My definition of ‘Garage lab’ just got violently upgraded…
That is an impressive accomplishment!
Well done!!!

[dimtraveler]

Interesting... Being semiconductor professional, I think that this could be a good example for college labs, where students can craft their own transistors and do manual layout. With some extra addition of steppers to have good alignment. After that, one can transition to shuttle wafers for higher integration. This gives so valuable hands-on experience! Great job!

I worked in a small semiconductor fab in the summers of 1972/73, your setup brought back some good memories of what it was like back then. We grew our own silicon from a melt. All seems a very long time ago now.

[WarrenPostma]

This makes me so happy because it blows up this fear I have that if we have some kind of natural or man-made disaster (a big war) our society won't rebuild. With knowledge and skill like this, even stuff like this is possible in your own garage at home. Of course you have some pretty sweet gear. Awesome video.

A man of so many talents. I work in a plating field and am a guitar amp tinkerer. This is a little bit everything done right.
