There’s a Class 100 semiconductor cleanroom inside this backyard shed.

Ah, I can almost hear the sound of my white cleanroom safety shoes sticking to the tacky mat :D

Like Sam Zeloof.

@jwt0625 Would you be willing to release the plans and BOM by any chance? 🙏

@jwt0625 I'd be happy to help! but it's kinda like building a house? haha every shed/space is unique! But it used standard semiconductor grade and commercial materials. For me it cost ~20k, expensive but not astronomical if you have a goal.

What the hell. This is beyond ridiculous. Craft beer but for semis 👌🏻😂

@yacineMTB Do you have a current upper limit on the number of transistors you can make on a chip? The early 8 bit CPUs had only a few thousand.

@yacineMTB Right now I can do sub-micron features reliably (1990s) and working on i-line immersion which can do sub-100nm (2004ish). But as fun as it would be to make chips (and may for future content) these aren't viable at this scale otherwise, so I mostly do R&D for novel devices.

Can't wait to see what you are doing with GaN and the blue LED

Hey you recognized it! I do a lot of GaN research, including in the shed, where as fun as it would be to make chips from the 90s-2000s it isn't profitable at this scale, maybe for youtube content though? Otherwise I do more R&D on GaN for single devices.

Of course. Personally I'd just like to see how exactly you did it at all. Surely the GaN had to be MOCVD produced off site, but beyond that I don't really know.

Offsite MOCVD...for now... haha but then there are some novel chemical treatments and fabrication mechanisms. LEDs are also pretty simple, etch and slap some metal on there :P

We need more of this.

@BreakingTaps Uuuh subbed+🔔

I built a CNC machine and thought that was cool but boy did you set the bar high. Nice brother

I think @elonmusk would be interested in your first principles approach to manufacturing!

Fastest subscribe in memory. Can't wait to see what you build!

I want to be you when I grow up

@tylercosgrove @tbpn @johncoogan @jordihays get this guy on the show!!

@jwt0625 This is what makes the internet worth paying for

Needs airlock decontam. space, esp. from outside.

You can just do things

@MakeAugusta @grok what does class 100 mean ?

Absolutely outstanding

Class 100? How many classes are there?

Haha they are rough guides in terms of particles per box of air per min, but they roughly go by orders of magnitude, 1, 10, 100, 1,000, 10,000 etc. All depending on the job, like if you are making circuit boards it may be class 10,000, you dont need it as clean.

😲😲😲😲😲 shock

Outdoor air can have a far lower particulate matter count than inside. Use a glove box for even better results.

Subscribed!

This is beyond impressive.

@jwt0625 @backslashvarphi

Incredible. The equipment setup is very impressive as well.

Beautiful. Looking forward to your next posts!

This is awesome dude! May I dm you with a question?

Certainly, DMs should be open

Nice! Willis would be proud!

What’s your YouTube? Or is it x?

Dr. Semiconductor haha it was available, and is just another fun place to showcase content. (profile pic is an SEM of a silica nanoshere I etched that came out looking like a pig)

@BayStatePosture check this out

The filtration and air makeup alone would be larger than several of those 'sheds'🙄
