Unfortunately yes. Even people with a Master degree in Media technologie doesn't know on micro level how a transistor works. I think thats fundamental to know everything of technologie today.
That's because this is not part of electrical engineering. This type of thing is part of process engineering, chemistry, and material science. Of course this guy has hacked a transistor together in a cool way, but the actual science of this is beyond EE.
This video is ground breaking in the field of semiconductor fabrication to me. I've never thought of it as a possible DIY process. And surely the great explanation and deep understanding of what is the aim of every single step, makes it much more interesting to watch. Great Job Sam

So nice! This year I'm having a basic "electronic components fundamentals" course at college kept by a professor that used to do semiconductor research in the 80', it's so fascinating to see all the amazing processes he describes with nostalgia remade (with many simplification because it's not a university lab but who cares) by a new passionate person investing his energy in such an amazing field
This is seriously impressive work! I love seeing people push "home made" to the extreme. Especially when they're making my favorite type of active device. Whats the process like for making a GaN FET?
I had a channel where I did tech projects, and I remember thinking I might try to make a transistor from scratch, but quickly found it would not be possible with my resources. It's insane the level of specialization and generations of scientific knowledge that this small little piece of equipment rests upon. If society ever collapses, I wonder that it may be impossible to ever uncover this knowledge again without multiple centuries of consistent research.
Get the word out about this channel, there should be many more views. These are some great home brew semiconductor videos, thank you for sharing your efforts!
I was looking for more info on this topic, the only other was this lab girl who did the same, but didn't explain as well as you did. thanks for the informative video.
This is awesome. All that work. It's incredible. Thank you for showing this. It makes me wonder, man, if a person could create strips of adhesive materials and just build one with layers, like lego blocks.
I was under the impression that a mosfet had a source collector and a gate. now from your explanation I learn it actually has a source collector and a gay.
13:12 I would seriously advice against since the fumes are crazy toxic. Also you absolutely need to mention that it cannot be stored or handled in glass because it will not only ruin your glass but it will also contaminate your process.
Really nice presentation. Your pace is excellent... With your equipment and knowledge, I am curious why/what your looking for ? or just having fun ... If I had all that stuff I would be wondering what oxides do what in what combinations to which base metals / ad nauseum ... First one which comes to mind is titanium .. its oxides have very 'energetic' properties
Hi! What an amazing project! - just sheer determination.... By the way at 12:33, you mentioned that water doesnt wet the wafer post the HF dip. Thats actually because the HF leaves a layer of H atoms on the surface, and that'll go away shortly after the dip. (This was way back in 2017, you probably know that! And HF is HF, so be careful!)
Hey man you do a more than great job, you definitely have outsanding capacities, Thanks for sharing all this great stuff with us! Btw one question where do you find the silicon wafers? Do you think those available on ebay/Amazon can serve to start doing this? Thanks in advance!
Quite interesting. I wonder how many MOSFETs you could make on a wafer on that size now, having seen how much more sophisticated your processes have become.
no doubt to handle hazardous material their is standardise protocol of handballing & processing, nice work inspiring to upcoming talent & present professionals also thanks for such work cont., our good wishes always with you GD TC
It doesn't look like we'll see your transistors on Digikey anytime soon ;) But man, you made transistors at home!!!!! It was only a couple of years ago that I thought "when I was a kid, I had instructions on how to make a diode substitute... I wonder if you could make a transistor", going to various electronics forums and heard loads of people ranting "Don't be such an IDIOT! It's completely IMPOSSIBLE!" Well, I think you and Miss Ellsworth have got a thing or two to say about that "impossible". Watching this back to back with Ron Soyland making homemade vacuum tubes is cool... I'm beginning to think my soldering factory-made components to circuit boards is, y'know, a bit prosaic. ;) It's cool that you're doing this and it's fantastic that you bring us around your lab to watch. Keep up The Great Work.
I went here to learn how to make a transistor with my kids. We have made resistors, coils and capacitors but this looks a little more complicated and dangerous to me. Wow.
plz how can i dope silicon whith aluminium for p_type and antimony for n_type ?? bcs i dont have phosphor and boron ... i have just Al & Sb and thank you :-)
We had a thin and thick film clean room lab at our school. we did the etching, but the insurance companies wouldn't allow us to dope the silicon. we had the ovens and everything needed, but they still wouldn't let us dope the Si.....
*Sometimes when I run out of mosfets to make my blinking LED circuits I will make my own in the kitchen. Amazing. Thought emporium isn't sht compared to this level of DIY*
That's the point. What if you find yourself in a position where you can't get access to aliexpress or bangood anymore? Or what happens if they have a shortage of components? But the number one reason is to be able to do it yourself.

Do you realize that 99% of electrical engineering students graduate with a degree and never see this?
Unfortunately yes. Even people with a Master degree in Media technologie doesn't know on micro level how a transistor works. I think thats fundamental to know everything of technologie today.
Thanks god I'm in the 1% of them🤗
Sad story. i watched this and learned to make one for fun but never have a chance to get in an electric engineer programs.

So this man can make a computer from raw materials!
A n-type monocrystalline die is not exactly a "raw" material. This guy has really good skills anyway.
If it was from raw materials he would synthesize his own hf and make sand into the silicon wafers
@@Funnyfish458 then I should search for "DIY How to turn sand into silicon wafer" and "DIY How to synthesize HF"
The HF isn’t that hard. Turning sand into a silicon wafer….lol
Only thing left to do is scale it down to 5 nm. Great work, glad YT recommended your videos recently.
Get the word out about this channel, there should be many more views. These are some great home brew semiconductor videos, thank you for sharing your efforts!
thanks!
I've always wondered if it would be possible for one person to make semiconductors!
I love how you just have a box in your fridge labeled "POISON"

big thanks for this video, I'm researching MOSFET production processes for my game that I'm developing and this is a GREAT source! :D
Absoullute cool,did not thought this could be done at home.Thank you very much.
Very Nice way to Build...many thanks to you and your efforts , times you have spent for us...we are watching you from Iraq-Kurdistan
Incredible stuff - how many of us use devices and have no clue what goes into creating them. Let's have some more stuff Sam
This is awesome. All that work. It's incredible. Thank you for showing this. It makes me wonder, man, if a person could create strips of adhesive materials and just build one with layers, like lego blocks.
the problem is making it small.
I was under the impression that a mosfet had a source collector and a gate. now from your explanation I learn it actually has a source collector and a gay.
Sam: I’m going to make a mosfet
Atmospheric oxygen: I’m about to ruin this mans whole career.

You earned a sub!
13:12 I would seriously advice against since the fumes are crazy toxic. Also you absolutely need to mention that it cannot be stored or handled in glass because it will not only ruin your glass but it will also contaminate your process.
Your video tutorial making IC chips is very helpful...
Good job, you are very skilled, those wafers are incredibly fragile. It is interesting how such a complex device only costs about $1.

Thank you for sharing your knowleadge !!
Jesus fck, this is the best video I've seen. As an electronics engineering student I'm amused!
Jesus is great i say look into it what one learns via truth may be even a bit quantum sciences is crazy n lovenley great all is a trip this life
overbuilt automotive ... get help, my friend.
İ am an EE student i already have an idea on my mind how its made but still best video i have ever seen
This man is a real genius!
This is an absolutely epic video
It certainly looks like you've achieved gain, so it ought to work as an oscillator if you'd like to try. Congrats!
no shit sherlock.

Thanks sam. You are an inspiration
Great video sir.
Question: How have you soldered the wires? Conductive ink?
Yes, a conductive silver paste I think. We use in our lab for making contacts.
There are other ways, such as Ga-In eutectic or indium wire contact.
Excellent! Demonstrating high-tech understanding of chemistry and quantum theory. And in a "kitchen" lab :-)
Can we do that without a lab? Instead of a furnace can we use canthal heater?
Very impressive and inspiring Sam! Do you have any plans or ideas to make a metal layer on top of it to connect the individual mosfets?
Thanks, and yes I'm working on it :) Been sidetracked lately with other projects though.
I love your ZX81 avatar !
Excellent work
Awesome vid! Where could one find the photoresist to do this?
Great job and awesome video!! Thanks for share knowledge
Amazing stuff. Mind blown!
Thank you so much for the video Sir
That was amazing. What are limits of home laboratory in your opinion? Could you for example create some VERY simple processor in a couple of years?
+Marek Ardecki yes, that is possible. Main limits are air particulate contamination.
I went here to learn how to make a transistor with my kids. We have made resistors, coils and capacitors but this looks a little more complicated and dangerous to me. Wow.
Point contact diodes (i.e. crystal radio detectors) are pretty safe and easy though, can even look at doing a silicon carbide LED.
Wow this is great keep up the good work. Every thing is dangerous, u only live once!!
Great video bro 👍
Oh my this is amazing!
Amazing video. 8:40, there has to be a better way to break these?
Awesome videos and awesome skills.
But... You should get smaller sized gloves. Makes it much easier to work when they fit.
I am super interest, is there any private course? I can fly to USA to learn, thanks
It's so clear, thank you😆
This is ART
Awesome stuff 👌
Super mega, giga, tera good way to do mosfet, ı liked it. It is pure science 🎉
Thabk you for this i want to make the initial resources too. I want to mine the metal and melts it down.
Any demo about difference between dry and wet oxide on the gate?
Super! Thank you very much!
WOW !! very impressive !
That was excellent but I think you should measure the body diode....
plz how can i dope silicon whith aluminium for p_type and antimony for n_type ?? bcs i dont have phosphor and boron ... i have just Al & Sb and thank you :-)

do they make transistors with both a negative and positive gate, one on top and one on bottom?
Good project
Excellent video! :) .... Poison. Sealed and fresh!
Did I mention how this video is excellent? W O W

@ACAB\\ Mela BAKAta what religion are you talking about?
@@lazyh-online4839 It's a joke
@@GRBtutorials yeah, I obviously failed at understanding that, still don't quite get it sorry.
Do you know why a MOSFET with separate body & source (4 terminal) is not available in the market?
hello, i’m wonder where did you get materials
excellent dyi hands on skill , thank you for teaching !👍☺📚✏📐
凄すぎて感心します
How is your process not affected by dust ? The ICs are done in a very clean environment
are the Intel processor in our computer uses the same mosfet but in nano scale? or entirely the chemicals are different?
*Sometimes when I run out of mosfets to make my blinking LED circuits I will make my own in the kitchen. Amazing. Thought emporium isn't sht compared to this level of DIY*
could you sand blast with a fine grit to etch rather than using HF?
I want to builid audio amplifier with this device, can you make 4 pieces of N channel with similar characteristics?
What temperature did you grow your field oxide at? 2.5 hours seems awfully long for 5000A of wet oxide...
many many thanks
I am glad I can just buy the IRLZ34N for a few dollars...
But very informative video.
Seems fun.

Use patterned source drain area drawing make long effective field. Use photomasks photoresists and optical lenses.
