Hey /g/, how dope is that? Also, silicon wafer thread

Bulk silicon is indeed heavily doped.

They sell them on ebay. Wafers with more impressive and/or notable designs are often quite expensive though. You can get wafers with more simplistic ICs for relatively little cost

Can produce my own silicon wafer at home, even using primitive technology or is still impossible in 2016?

Is there any logical reason why you would fucking say that post is underrated? Has anybody expressed any kind of dissatisfaction or criticism at all against it? Are you delusional? Are you reading replies that are nonexistant? Maybe you come from communities with voting systems, but there is literally no way that you could know what other people think of that post you just replied to here. Maybe it's psychological. Maybe it's your own post you're replying to, like a 12 year old fucktard liking his own facebook posts thinking his swelling autism is going unnoticed. Maybe your self esteem depends on you tricking yourself into thinking someone out there thinks your post is worth something. Or maybe you are just a retard, the worst kind of retard, the one who thinks he's smart, the one who thinks he's the only one to have gotten the joke, to have understood the post. Well, guess what, faggot, that post is by no definition underrated so why don't you do the world a favor and go check out what the bottom of your toilet smells like?

I worked with 4 inch silicon wafers and they were about 100 dollars each (virgin). When you add lithography processes to it, the price goes up exponentially.

One of them is shared prototype, probs some kind of CPU and photo sensors. Second one is some kind of data storage with uC, probs ram.

I only have a couple chips I designed and an intermediate 5" MEMS wafer I processed.

Though a whole wafer would be nice, how much do 300mm reject wafers go for?

The silicon plates are grown as one super-pure crystal. Like a snowball rolling down hill, it's not gonna be a square

>>56010893

>>56013744
does this mean my mom has crystals in her chest?

>>56013483
They're created from a circular crystal.

>>56013803
cylindrical* oops

>>56013763
Your mom is the opposite of super-pure, just ask the legions of people who've injected their code into her

>>56012927
I bet that was an Itanic wafer

>>56013860
you don't need to tell me that. at least she lets me do it too

>>56008691
How and why are they made like that?

>>56014051
High purity silicon is placed into a vat and heated until it melts. Then a wire is lowered into the molten silicon and they slowly and carefully pull the silicon to create a cylindrical crystal at a specific dimension. Then the crystal is sliced into thousands of razor thin wafers.

Give me a couple million dollars and I'll show you how to make a proper CPU

>>56015474
they could, but melted/formed metal has inconsistent internal structure
silicon used for wafer production is grown as a single crystal

>┌∩┐(◣_◢)┌∩┐
I'll give you a few bucks for that autism medication you've been skipping out on

>>56015474
The silicon is grown the way it is because it is an atomically uniform single crystalline structure. There is no variability in the placement of atoms within it. Thats a must when building small scale devices. Bulk silicon especially is treated with numerous additive metals, insulators, special sauce to prepare the wafer for the building of source/drain wells and channels. They aim for near atomic uniformity here, and if there is any variability in the wafer itself it will negatively impact the performance of every transistor.

As someone with an IT back ground how can I learn more about how CPUs are actually designed? Like for AMD sitting their team down tk develop Zen, how do they do it? Are the circuits designed in software? Etc. I am so fascinated by hardware bit don't know much about how it truly works

>>56015453
Is it possible to use one of those as a dildo? Where would one buy pure silicon dildos?

>>56016693
ARM uses software for simulations, I assume the rest of the cpu guys do as well

>>56016693
Complex ICs are usually written in a "hardware description language". They can also be simulated, basially someone writes a simulator of how the CPU is expected to work in a high level programming language and they compare the actual hardware to it.

>>56016693
Also here's a rather long video that kinda goes over some of the processes

https://www.youtube.com/watch?v=eDmv0sDB1Ak

>>56008700
P-pls explain

>>56016813
Doping is the process of depositing atoms into a semiconductor material like silicon to give it the properties of a semiconductor.

>>56016813
https://www.youtube.com/watch?v=k0J_y0Av_f8

>>56016693
Read Hennesy&Patterson's books

>>56016788
They have to guess a lot from what I understand, since the models they make only run at a fraction of the speed and with a lot less error than the actual hardware.

>>56017046
Take a look at Intel's errata for their x86 stuff. You'll realize that it's a miracle that these things actually run.
