Is it possible for an average person to grow a homemade monocrystalline silicon ingot big and pure enough to make at least 1 functioning microchip?
>>
sure but you are not going to make a chip out of it

I still don't understand how chip fabrication works.

just buy a blank waffer

Probably be one of the first technologies to fall out of use. We'll run out of enough people smart enough to do it.
>>
>>16547122
That's kinda helpful but I'd like to see what individual logic gates look like on the wafer. Also, is it all just a single layer?
>>
>>16547089
Probably? But that’s like the least important part. You can just buy em online.
The hard part is having a working photolithography setup and the means to apply stuff to your wafer.
Producing integrated circuits at home been done before though, and it’s one of my personal long term goals.
>>
>>16547089
Yes. But can you even grow a single block of salt first?

Your electric and/or gas bill will be horrendous.

People have been doing DIY semiconductors in their garages for decades anon.

Well, with what passes for average today, I am not so sure. Still, an average IQ dude with patience and willingness to learn, fail, try again (and probably a dash of autism) can do it, yes.
Silicon is a relatiovely forgiving material, and you can get quite a bit with plain shadow masks and avoid big mask aligners. The 6502 was made at a 3 um node.

Of course, if you do this, and it is possible, I will be happy to shake your hand and congratulate you on this monumental task.

>average person
What do you mean by this?
>average income
Yes, such a person could grow the crystal.
>average intelligence
Not a chance.

some rich girl on youtube shows how to make at least one transistor with equipment she has in her house. Some people make chips with thousands of transistors which... can do some calculations.
Its said it get hard when the transistors get very small because then you need ultra cleanliness, any dust, grease gets in the circuit and breaks it.

>>16547089
silicon really likes oxygen, so no.
>>
>>16547190
Just get chatgpt to do it :)

>>16547574
From wafers?

>>16547089
An _average_ person? No.

OP asked if an average person could grow a mono-crystalline silicon ingot of sufficient size and quality to make a functioning microchip. The answer is no. The average person does not possess the requisite equipment nor the expertise to use it, nor the motivation to acquire those skills and equipment.

I'm actually rooting for the Chinese to figure out fabs because literally all of modern civilization hinges upon the production happening inside one giant building in Taiwan.
>>
>>16550777
Taiwan are Chinese too.

It's a process mastered in 1915, it's well within reach of enthusiasts willing to spend some bucks. Pure enough to do some lithography and chemical etching to make working field effect transistors. Not fucking 5 nanometer microchips for your gayming console.

>it's well within reach of enthusiasts willing to spend some bucks
Sure. But not average persons.
>>
>>16547190
Not true. Some groups never rise. Look at abbos

That's a really wordy way of saying

Patents exist and are readily available for free, online. All the techniques have tutorials on youtube.
>nor the motivation to acquire those skills and equipment.
