Making Microchips at Home - Cooking with Jeri Part1

[@witchdoctor88]

Years later this is still one of the most incredible videos I’ve ever seen

[@gregorymalchuk272]

"Hi, I'm Jerri Ellsworth, and today we're gonna be making semiconductors with a toaster oven, a tea kettle, and toilet bowl rust remover. :)" This entire video is honestly incredible.

[@edgeeffect]

I first discovered your work because I'd seen homemade diodes and wondered about making transistors. "You can't make your own transistors" said all the detractors on everything that Google turned up. Then I found this cool American woman who'd been making her own for ages. :)

[@DoRC]

Anyone that doesn't get why rolling your own semiconductors is cool is probably watching the wrong part of KZbin.

[@buildingbloxs6202]

I know right!!!

[@aorusaki]

hahahah yup

[@SameBasicRiff]

great comment and name.

[@itsnoam338]

Ha lol

[@forlinginst]

Why didn't we have teachers like you for chemistry and physics, not to say electronics? You are so clear in your explanations and totally without any BS.

[@eavids128]

Very cool! I was looking at Sam Zeloof's recent videos and I wanted to learn more about the history of homemade chip fab. It's awesome that you were able to do this years ago with less equiptment

[@umutpiynarr]

I remember first time I watched this video when I was 11 years old, now I am watching it again. After living many things, trying and failing and maybe not even trying well and failing many things, now I see there is still something I love in this world. Noone will get it but only such things prevents me from suicide.

[@NightRunner417]

You're frickin astonishingly intelligent, creative AND funny at the same time. The cool scale doesn't go high enough to properly register your true potential. :-)

[@martinda7446]

Hahaha. Did you mention ''common sense''.... On KZbin? Seriously though I loved this - and what sort of numpty would complain or moan, its pure gold! ( also I knew it was magic when you said you dropped your wand)

[@TheCrakkle]

The good in building transistors at home is that you can do it and it stems the tide of "Gollums" pretending that science is a black art and only machines can produce "Tech". We need to keep in perspective that Humans create this stuff. Great Video as usual :)

[@Ryukikon]

😶😑🤫

[@aaronmosey3637]

"My bones do feel a little gelatinous though.." :) :) I love it!! Super video, love the humor AND the science!!!

[@Xinfinitude]

I know nearly nothing about electrical engineering, and yet I still find these videos interesting.

[@chrism9598]

I came here to learn how semiconductors are made....since I teach new operators basic electrical theory at a commercial nuclear BWR and realized that I don't know how they make NPN (PNP) devices. I greatly appreciate your time and effort to teach these principles and your enthusiasm is contagious. Keep up the great work and let me know if you are interested in working in the nuclear industry.

[@Mackinstyle]

I love when videos chain together to show something complex beginning with very simple things.

[@an6366]

You had me at 0:05. Apparently, I had been living under a rock before now. I admire your mind and I’m glad to know of you.

[@cbriangilbert1978]

Wish I had a friend like you back in the day.

[@micky9229]

19 people thought the title said making Microwave Chips at home. lol

[@Ciprian-Amarandei]

Wow...I always dreamed of making my own microchips. I don't have the knowledge to design a circuit from zero, but at least now I know it can be done. Such a great video. Thanks Jeri and thanks internet :D

[@KRT054]

Keep going Jeri! And don't pay attention to those goofballs who think you're faking your transistors. I know better!!!!

[@Nomoreidsleft]

Nice demo. Many people don't realize that etching silicon is similar to etching PCBs. The hard part is growing the silicon cylinder and cutting it into wafers. That's where you need mult-million dollar fab plants.

[@JosipMiller]

Jeri, you made my day ! I am also engineer and sometimes ideas like this are crossing my mind but I never tried. You actually did this. Keep up the good work and thanks for the videos.

[@AllThisThen]

even just watching this video for half a second makes all your youtube suggested videos suddenly awesome

[@RasmusSE]

Wow. This is so brilliant that I don't know where to begin. Is there anything you cannot master in your home lab? You must seriously be one of the most talented persons alive on this planet. *speechless*

[@ThiagoVilla0]

Jeri I have seen only two of your videos and I already love you.

[@charlesokoh3373]

Wow I’m wowed studied this 2years back just didn’t have the patience to look for this video This is sweet everything’s clearer now #Thanks

[@TheWinnieston]

I'm currently etching my own pcbs at home, and I'll look at through hole plating too. This is a completely new level you have opened me up to!

[@sbandc]

Some people recognize that the skeptics and critics aren't the Teslas or the Newtons; and they often hold your work with no small amount of gratitude... perhaps even a hint of envy.. so thank you. :)

[@calthmlikiseethm704]

The people who doubt you are just jealous of your awesomeness... Smile I think you fantastic...

[@DaveUK66]

I am glad you did not die - hope your gellatinous bones are better - excellent work as usual!

[@syn010110]

We need more people like this, period.

[@dchurch2012]

Agreed! This is a great video and proves what can be done by 1 person who is determined!

[@charlesurrea1451]

11 Years later and I'm just NOW seeing this? Still so very relevant.

[@jameswasil]

I love this. You're the Betty Crocker of Lithographic Engineering, Jeri. :) Excellent video!

[@undeadpresident]

How come schools don't teach jack shit about electronics despite the fact that practically everything we use is electronic nowadays?

[@GuiFalked]

Because VoTech is more profitable?

[@bighands69]

Because schools are out of date run by out of date people. Think about it children sit in a room from the age of 4 to 18. And if they are really good at that they go and sit in a bigger room for several years after. And after that the person is ready to go and get children sit them down in a room and control the whole room.

[@SianaGearz]

bighands69, i don't think that's the case, i think most people regardless of age or education realize that science and engineering is what drives progress forward, and electronics is a pretty accessible and practically important path. I think it's because they want to eradicate free thought and promote consumerism.

[@undeadpresident]

I think you are both right. They want to eradicate free thought and control people by raising them in a room

[@enorbet2]

In the TLDR age of "let somebody else do it" you fucking rock!

[@fluxx1]

You lady are my hero! A weird kind of hero, but a hero nonetheless. You have my biggest respect.

[@adammadron2080]

You are amazing Jeri. I accidentally stumbled upon your videos while sifting through various stem stuff available on KZbin. I am very intrigued and impressed with how you got to where you are now :D The world needs more Jeri Ellsworth type ladies. Thank you for sharing your knowledge! I know this is an older video, but it is new to me since I have not seen anyone else doing this sort of thing on YT except you.

[@blakekarbon9428]

I'm so glad someone is doing this! Gunna have to watch all these!

[@ArruVision]

This video has two of my favorite Jeri quotes: "getting tired of people claiming that my transistors are faked" and "before you get all preachy about hydrofluoric acid". Wicked!

[@FlyByPC]

This is awesome -- creating microchips with Aquafina, rust remover, and a steam kettle. Great explanation, and as usual, it looks like you've found a way to get results for cents on the dollar. (Bus turn warning systems, anyone?) Thanks!

[@ubidefeo]

you and Ben Krasnov are definitely my favourite 360º makers :D hadn't seen any of your videos for a while, and today I decided to randomly watch some. kick-ass, Jeri. my best regards u

[@RobertLBarnard]

Thank you Jeri. I'd never thought about making chips at home, now I am. Very inspiring!

[@IamBananas007]

common sense... is not too common these days. great work! love the video series.

[@sniffy6999999]

Jeri. I wish I had a fraction of your knowledge and 'get up and do it style'

[@sniffy6999999]

I'd go to part 2 but part 1 is 'busting my head'.

[@DOGPOOCHOGENIUS]

You are amazing a genius, beautiful woman. I always thinking about what makes people very smart, but I don't see them anyway. But this lady have multiple knowledge about every aspect I can see that in her. This wonderful lady got specific unique look that indicates very high intelligence almost not Earthly.

[@vampifrog]

Hi Jeri! If you need new bones you can buy from ebay! Thanks for the video!

[@BrightBlueJim]

@bmdawe: if you have to ask "why", nobody will be able to explain it to you. @jeri: you rock beyond all limits.

[@jeriellsworth]

@cpypcy Education, hobby, etc. What is the use for making anything at home that can be done better in mass production?

[@ЯношКабанчик]

We'll need new ics after the 2021 apocalypse!

[@kiteinthesky9324]

Because you should know how to make your own things, you petty consumerist child.

[@kallekillerapa]

OMG, be careful with that HCL! There are a number of occurrences where HCL has spontaneously jumped out of the container and on to innocent people. X) (awesome video)

[@VincentGroenewold]

Way to ignore what she mentioned about it at the beginning. :)

[@ryanpayne9119]

@@ElemparuMC Its 2% HF. I've seen KZbin videos where people rubbed their hand in this exact product while cleaning their sink. No gloves, no medical attention, still alive three years latter. Not that I'm suggesting you can be careless.

[@iamtanmay]

​@@ryanpayne9119 Rust cleaner is fine. But you do have to warn people NOT to buy 100% HF and try to dilute it down With all the jokes Jeri is making, a novice with no experience with acids might do just that And then yes, they will lose their limbs, eyes, lungs, as they try to tip the jar of 100% HF into a container of water. HF is scary. Working with Piranha and Caro already bothers me, when after a year, every lab worker has unexplained large holes in their brand new lab coats. These acids are invisible when they get on to you. Risk your life at your own peril.

[@MrTeneric]

Used to work with HF liquidfied and aq. It can be very dangerous depending on concentration and temperature. Been burned once or twice. You are taking very reasonable precautions (more than I would have probably). I've got to say that you doing what had to have been done in the lab in the development of this tech should not suprise anyone. Nor the fact that you are an attractive woman. The fact that you are doing it is just plain cool! I admire your inquisitive mind. You are rare.

[@Moronicsmurf]

Common sense is so rare these days it should be considered a fucking super power.

[@geronimostade8279]

Smart girl! Enjoy your videos, just stumbled over your videos... great job! Cheers from Germany

[@dale116dot7]

This is very refreshing! I have thought about making my own IC at some point but I haven't done it yet, this is great! I bought a thermal evaporator that I use to make condensor microphone diaphragms off of eBay, Something like that would be a perfect addition to your setup if you wanted to deposit metal interconnects.

[@dd884e5d8a]

So impressive, Jeri! Thank you for the video.

[@VincentGroenewold]

Ah I see "people writing it's fake" started around this time on KZbin. Jeri, you're amazing, I hope you don't get annoyed too much anymore after these years. It's the only way to survive on YT it seems. :)

[@mrspelly7150]

This is what I always imagined a modern McGyver doing in his kitchen. Got no base circuit-board, just dry out bananas under pressure. Lacking a sepparating coating for wires in a electro-magnet? Use duct-tape. In fact, toss out the banana, dryed pressed duct-tape works even better. If there is any duct-tape left, you can fix any open wounds, just make sure to rince it in bottled water, or UV-sterilized rain-waiter. I have no clue about electronics, but this just seems cool no matter what

[@TVPiles]

Nice job. And for those who scream fake: 30 tears ago the amateur scientist already published an article on how to make some transistors at home (then in thin layer technique)

[@colzaidikari]

I like your mommy voice! YOUR AWESOME!

[@Mtaalas]

For all those haters: "faked" = do the fucking experiment yourself and if you can't reproduce the results you have a point. "what use is one transistor" = learning and fun? what the fuck did you expect? return of Jesus? :I Don't mind the haters Jeri...

[@davidkeller6352]

Jesus Rules! Seriously.

[@JohnDoe-gm5qr]

I am thinking of that scene from the Wizard of Oz where they threw water on the witch. I'm melting!

[@JustPastAlaska]

Jeri, carrying the fire.

[@jeriellsworth]

@ngneer999 I'm running oxidation for 6hrs. I have extra tubes for mine if I wanted to keep dopants separate. I don't at the moment.

[@technician-tony]

I could listen to you talk all day! You sound very attractive, I'm sure other guys agree. Thanks for the video!

[@richardhince9764]

Coming from the UK as I do, it's always a bit funny for us to hear the word 'sodering' (we say 'soldering'). Especially since we say things like 'silly sod' (meaning a slightly daft person) and other ridiculous colloquialisms such as 'sod that'(!). I wonder how these words diverged... anyway, great video. I didn't even know that a semiconductor wafer could be purchased until I saw it. I'm an N-type kind of guy, by the way, I should mention that.

[@AV1461]

I still find this awesome.

[@JosipMiller]

I am working in a mass spectrometry lab (maintenance technician) and one day I was surprised (i did not had mauch experience back then) when dichloromethane actually penetrated through the nitrile gloves while degreasing some parts of accidentally 'oiled' instrument components. :)

[@MillicentOak]

A friend linked to this, and for some reason I was expecting microwavable starchy goodness. But no worries, I couldn't figure out why she wouldn't want to deep-fry them anyway! This is far cooler!

[@StarGateSG7]

FANTASTIC JOB !!!! Great Work !!! This is the start of great things for you! As an microcircuit enthusiast in Vancouver, Canada who has dabbled in a tiny bit of CPU/DSP circuit design, I've been looking for just such a KZbin channel as yours! I have been eagerly looking for a way to do what you have just shown at home for many years. I've been itching for a way to not be so beholden to the wayward scheduling of our parent company's chip etching system. You have given me some incredible ideas and I think I just might be able to figure out a way to semi-automate SOME of your processes using home-built high-temperature-resistant 3D printers built from ink jet parts, ceramic and a do-it-yourself vacuum chamber! I think IT MIGHT BE POSSIBLE to dope the chips using a process similar to thin-film vapour deposition within a DIY vacuum chamber made from an old 20 lbs barbecue propane tank containing a TINY sealed printer head taken from an Epson or Canon inkjet. You will probably get a much more diffuse distribution of dopants using the nanoliter/picoliter capabilities of modern (and CHEAP!) inkjet heads! You might need to spend MAYBE $500 on parts and another 50 hours on assembly for the print head containing vacuum chamber. The SAME type of ink-ket technology could also be used as a DIY chip cleaning system within a SECOND propane tank vacuum chamber to spray solvents and/or specialty washes at nanolitre/picolitre amounts. For the chip masks, I suggest old large format ink jet printers you can buy off eBay for less than $1000. Just make sure their resolution is 600 dots per inch or better and PREFERABLY 1200 dots per inch or better. Print each layer of traces onto optically clear film using full black ink only! I suggest printing onto: ORAJET® 3352F Optical Clear Film from Orafol Corp or similar types of optically clear film. Print your traces and layers at 600 dpi or 1200 dpi at up 36 to 48 inches wide. Using such large prints for your traces means you can using a CHEAP DIY LED-based Infrared light array to expose the large film sheets into a CHEAP but truly optically clear high refractive index plastic focusing lens sourced from an optical supply store. You just need to build a large enough film-sheet holding frame (48 x 48 inches) and keep the plastic film electrostatically held onto a clear but very stiff 1/4 inch thick polycarbonate sheet embedded into the holding frame. The plastic-film-based printed trace sheets MUST be held on UNDERSIDE of stiff polycarbonate holding sheet to ensure less ragged trace edges when the Infrared exposure is reduced to micron levels. The large inkjet printed traces should then reduce quite nicely down to micron-level traces. It should be QUITE POSSIBLE to do two micron or even one micron circuit traces at enough accuracy that it is FEASIBLE to build a DIY 16-bit Intel 8086 CPU AT HOME !!! My estimate is around $1400 for the IR LED array parts, focusing lens and sheet filmholder parts and $100 electrostatic charger and the stiff polycarbonate sheet. So for much higher end performance chip making AT HOME, I think it's DEFINITELY feasible with around about $2500 and about 100-to150 hours of build time. Best Wishes and GREAT JOB !!!!

[@JasonRobards2]

"I made working devices, so..." is something I might use myself

[@jamest.5001]

I know this is an older video. and I know only what you have told in this video. but I'm asking could a whole or large piece of wafer be used to build a large high current transistor. it probably doesn't work that way does it? now that I'm thinking a little more. it is probably like how you get higher current capacity with MOSFETs. like there is a difference in a lot of wire. a long thin wire isn't the same as a short thick wire. even though they are both a lot of wire! like I said I know nothing! great video. I'm glad I came across your channel.

You are one amazing young Lady. I done tv repair for many years. now that I'm older I fiddle around with smaller electronics. Memory isn't what it use to be. After having open heart surgery something didn't go as it should so it's taken a big toll on my memory. Hopefully someday I'll remember what I use to know. I very much enjoy your video I think your doing a super job. May The Lord bless you 😊

[@hbira9955]

I watched your Homemade transistor video of and I want to do the exercise at home myself and make a transistor. Need some information like from where to purchase a p-type blank wafer. How to injecting n-type in to the p-type. From video it is not clear to me, how to fuse the n-type in to the p-type? Also how do I obtain the n-type materials. I have a bench, voltmeter, soldering station, scope, but not an hoven. Thanks

[@Donatellangelo]

That is quite impressive.

[@young10man]

Your experiment was great. But, I have few questions. 1. What kind of wafer did you get in ebay?( please, Copy-paste the product name from eBay) 2. How do you arrange the circuits on fininshed wafer? (Give me more detailed description on how, because it doesn't say on your 2nd video. 3. How do you make transistors and IC from it? Thank you for giving me a great video.

[@VeLawrence]

Hj Jeri what an impressive video thanks for sharing! I do not know if you still read comments but may I ask you where do you get wafers from? Do you think those being sold on Amazon or ebay are good to experiment? Thanks in advnce!

[@HeatherSpoonheim]

Ok, I thought I was kind of smart but not so much anymore. I can, however, bake bread and make beer - so if you need a baker/brewer after the apocalypse, please pick me because I want to be in a group with someone who can science the hell out of stuff in my group, :D

[@TheBaconWizard]

+Heather Spoonheim I will bring/make bacon :D And can also bake/brew a little.

I'm running a very similar oxidation furnace right now and really it's not much more sophisticated. It has boiling water and 1000C. Don't allow dopants or metals in mine though. How long did you run your oxidation? I'm running 17.5 hours for about 2um. Also note that I'm not scolding you about the HF.

[@marktirabassi7160]
