How To Make A CPU
2021-11-09 – By Robert Elder
The aim of this text is to clarify how you can make a CPU out of rocks and sand as quick as doable with out utilizing too many phrases. Because the world of proprietary {hardware} and software program crushes in round us, we danger dropping the power to make issues for ourselves as people. It is for that reason that I felt compelled to find out how one might hypothetically make their very own built-in circuits by themself. Skip to the tip of this text for a couple of extra phrases on this topic and a disclaimer.
WARNING: don’t try melting silicon at 1698 °Okay in your kitchen house oven.
WARNING: don’t place your fingers in molten silicon.
Additional studying: Boule, Czochralski Method.
I used to be not courageous sufficient to purchase elemental phosphorus, so you will have to make use of your creativeness with the matches.
And that is the way you make a CPU. Additionally, see CPUs Are Smaller Than You Think for a glance inside an actual Intel CPU.
Clearly, the method of creating a contemporary CPU is extra difficult and fewer well-defined that depicted by this text. Each new technology of chips normally makes modifications to the way in which options are constructed up on the wafer (not simply when it comes to function dimension). Many frequent methods should not even talked about on this article, and lots of vital steps have been not noted. Vital particulars (akin to exact chemical compositions/concentrations) are extraordinarily proprietary and you will not see anybody describing them on HackerNews or Reddit. Many steps within the course of (akin to sourcing and purification of the silicon) have multiple generally used technique. If you wish to study extra about these subjects, the correct search phrases are “Superior Optics For Photolithography” and “Chemical Deposition Nanofabrication” or “Lithographic Metrology”.
Though this text is not good, the hope is that an reader will profit from utilizing lots of the subjects mentioned herein as search phrases for additional analysis on their very own.
Whereas cutting-edge nanometer scale options should not prone to be accessible for a hobbyist, micron-scale novice chip fabrication does look like fairly possible. I’ve not tried this myself, however Sam Zeloof has, and you need to undoubtedly take a look at his YouTube channel. I feel you could possibly in all probability even construct some primary chips with far much less gear than he has in the event you get the optics proper. You may in all probability make it a pastime enterprise promoting cusom chips to different tech folks!
A Phrase Of Warning: In case it wasn’t already clear, I do not advise that anybody truly try making built-in circuits of their house within the method proven on this video. The ‘photoresist’ and ‘developer answer’ on this video is only a coloured prop. The true chemical compounds are normally hazardous and you need to solely work with them with correct security gear in a effectively ventilated space or in a fume hood.
