This setup is beyond words and the way you organized is outstanding, from safety to experiments.This video will always reminds me days of Shockley an early days of semiconductors
Somebody get this guy a Flux Capacitor and a DeLorean! In all seriousness, genuinely outstanding work. Just read a Wired story about you and I’m a fan. You will go far, please teach others, and help the world with what you learn. I’ll watch for you.
Wow! I both admire and envy this. Thank your parents as many times as possible please. If I got any of this stuff they would complain that I'm wasting money and would hurt myself or burn the house down. Got very little encouragement back then. Still kinda do..... Even though I work for what I have and finished college. Keep up the great work. You're going places. :-)
This is awesome! For those who want to build such labs please be aware: You must collect and recycle the chemicals in a facility you can not use the drain to discard them! That is extremely important. Please, pay attention to environmental safety.
Also: read up on emergency procedures in case you get some chemicals on your skin and find out what hospital close to you is able to treat chemical accidents (this may mean the difference between just a little accident and a lost limb). E.g. if you work with HF: have a tube of Calcium cream in your first aid kit and be prepared to use the entire tube on your hand after getting a few drops of HF on it (at least that's what the safety trainer told us last time I was in a Fab). In the 70s building semiconductors used to be very dangerous to the environment and health - this has changed massively today - it is one of the safest and cleanest industries. Not because the chemicals changed (they got worse), but because we have learnt from the mistakes. Please read the safety data that is available - safety data sheets are always written in blood, avoid it being your blood. ;-)
Do you care so much about how the lithium in all of your daily use devices is mined and the damage that is done to the environment and to the children who mine it? My guess is that you probably don't give it much thought at all considering it doesn't stop you(or me for that matter) from buying and using them. It would be hypocritical of us both to presume we care about the environment but yet still use the products made from it.
That vacuum chamber brings back so many memories of my internship at a research facility. We had most of that same equipment. Never thought I'd see it again in someone's garage.
Wow, your lab/shop is really impressive. Way to go! I like some of the improvised mounts and systems and I am personally working on a boom for a stereo microscope and found humorous the vise boom. Never thought of that way. I used to perform audits in Ag, Food and Drugs... so I have this impulse where my only observation is PPE and ventilation. Be safe and keep the work flowing. Way awesome!
ECG book had tens of thousands of different ics in them with diagrams of internal layouts.Use to get them from Randolph and Rice in Louisville and later in Nashville from Randolph and Randolph. Politicians decided to give our technology to Japan to help their economy and thus started the throw away economy. TVs were average 800.in late 1970's and early 80s bought many a 1000 PIV diode for repair of lightening surge voltage at 8 cents each. Use to be many tv repairmen and TVs got fixed, not thrown away! The good old days when there was only 1 kind of electronic solder and you didn't need an oven to control cool down times for ics with different mix solders for right temp mix so you didn't destroy ic or get a cold joint in a short period of time.
This is all fantastic, but is this really at your _home_? I think you may have crossed the line into having your own Private Research Lab, rather than a "home lab." Regardless, megakudos! And I am _dying_ to see some characteristics of those fets :-)
It does cost a bit, but a lot of equipment can be bought rather cheaply used from old labs, old manufacturer lines, and universities. It is important to have a lot of space to organize everything nicely. A lot of control stuff can be done cheaply these days from scratch using arduinos and rasberrys, and few off the shelf stuff and proper not that hard to write software. Finding a microscope or a high quality vacuum chamber is hard, but all doable.
Wow, I wish I had the space and the time to make a hobby out of chip making. Please continue to share! I feel like you could inspire a lot of people, the whole thing seems to be ver intimidating, but not impossible. I am sure more videos would help educate others and help them feel confident enough to try this!
Super cool man! I am temporarily working in the clean room for a tool-install for a semiconductor fab. The machines they use are absolutely incredible and the knowledge of the folks that do this stuff is amazing. I love seeing the same machines and processes done in a DIY fashion. Keep it up! Whats your background with this? I assume you have worked in a fab or currently do?
WOW! its crazy how we take for granted, the tech we use to make IC's and microchips. Not only electrical theory, but chemistry goes into fabrication of microelectronics. Once the knowlege is forgotten, its surely gone.
U are the Grate Sam I want to learn some Electronic Skills from u but I m From Pakistan I love Electronics very much But we don't have that much innovation in technology
That modified optics looks like it has a roll of tape on it... Is that what you did? Really awesome that you've tried to do this, never thought anyone would go this far.
hello, great video. I am trying to make a photomask by sputtering chrome on a piece of glass or acetate. Next, an conventional artwok acetate sheet featuring the larger layout will to be placed in front of a basic lens setup so UV light passing through it can reach the chromed piece covered by photoresist. will it work for a 25-50micron final imprinted feature ? appreciate any suggestion
13:43 i noticed you havent been making any videos lately. is this related? im actually working on putting together a setup based on some of your designs, and i think this stuff is super cool! thanks so much for the videos and the hard work!!
I really want to start a Semi Fab business, and the obvious first step for me, is to start at home- then expand from there. I'm a layman and a hobbyist and a big problem I- we, have in my country- and area of the world, is that electronic components are relatively expensive since they need to be imported and you don't always get what you want- you have to sometimes order and wait a few weeks. Our economic supply still rely mostly on Importing. My country is at the start of the Manufacturing phase in our development- having moved out of the almost complete reliance on Agriculture relatively recently, Electronics have become my passion and I see this as a great opportunity to supplement the various industries and also to develop a business. My question is- starting out- at the technical level, what education/knowledge do I need to start a semiconductor fabrication business? I'm thinking, I need a degree/diploma or equivalent in Chemistry, and Electrical Engineering? Is this correct, or are those a bit overkill? Time is always of the essence... What else- apart from the business aspect, is needed? Thank you for your time.
Hey Sam, it's really great what you're doing here! Would it work to use a CNC or scanning UV laser to expose the photo resist instead of the DLP? People have done that for PCBs, and in fact I'm fixing up to do that myself for PCB solder mask exposure with a scanning focused 405nm UV laser diode and laser printer scanning optics.
No not many have, I have considered it, etching shouldn't be a problem, if anyone has an electron microscope, they can modify it to etch at scales of less than 5 nm, the problem is he heavy machinery needed for sputtering and deposition of conducting material. Also alignment, but you can buy nanometer precision alignment tables.
I wonder if this setup would allow me to copy some of the chips off the SGI Tezro. After they went belly up and merged with Rackspace to form new SGI, they stopped making the Tezros, and some of the chips were unique to them so you can't assemble them from parts. Might be possible to copy hard-to-find C64 chips, too.
So cool man.... I just want to what are u going to do in this lab.... I mean how that is going to help u... Please tel me... Im also curious to know Are u only make for youtube....!????
Kinda late to this but when you mentioned HF, I'm so eager to do a NurdRage style warning/disclaimer. "Warning! This is some crazy ass lethal shit. If you touch hydrofluoric acid YOU WILL DIE! (painfully)"
In fact, I am working on a DC sputtering DIY (already working) and RF sputtering for isolating materials deposition and the sputtering guns. We can exchange some info. Are you a graduate student?
Really great! But i don´t get it at long last.Is this a hobby or part of a professional,commercial(educational?) business? O.K. some people rebuild or restaurate old technics like oldtimer ,planes or so .So why not 70/80ies-electronics one could say. Btw.: A (electronic?)-microscope would be interesting to show the result. Some years ago i decappted someold chips up to mid-90ies mechanically when you still could see the structures. Looks very interesting under a 1000X-microscope
You say that you don't see other people doing this, I say to you whenever you buy a piece of equipment you need to get an extra one and mail it to me. I'd love to be making semi conductors there's a back order of PlayStations for days because of the global shortage of semiconductors. I'm trying to get paid yo
Very cool! You have built an incredible setup!
Thanks Ben! I appreciate it.

I must get started, now that I know it's possible…
wow, you've got like at least 15k+++ $ worth of equipment there at least. Really nice!
that vaccum chamber alone is prolly worth 15k
Dude should open up his own Workshop or Class and make some money. I don't know where he's located, but I'd fly down there in a heartbeat!
I would attend his classes too! - If I can get a place and some tools, I will definitely open an electronics research group…
Just read on IEEE Spectrum about you. You are incredibly innovative. I hope you go on inventing some cooler stuff to help the humanity.
How far way is your lab from creating an actual IC (like a small 4-bit accumulator CPU)?
