Take a dustpan to the river to catch some dustpan sand, and melt the sand in the prepared shaft furnace or thermite to get silicon dioxide. However, because the silicon purity of IC must reach 99.999999999%, silicon dioxide should evolve into a "silicon single crystal" step by step like a digital baby. Many individual players are stuck here. I hope you can get through
Monocrystalline silicon needs to be cultivated. After practice, you can rotate clockwise with your hand that you have dealt with five girls for 30 years, reaching the third cosmic velocity thrust that can make you fly out of the solar system. With this high-speed rotation and intense air friction, the newly formed silicon ingot will be as uneven as if it had been chewed by Hal, so it needs to be polished and cut.
Use a grinder and 5000-mesh sandpaper to carefully grind the manufactured pure silicon ingot into three-body filaments as smooth as water drops. Then the silicon ingot was cut into pieces with the thickness of 1MM by NVIDIA's old yellow knife, and the surface damage of the cut surface must be re-polished.
Borrow glue, correction fluid, paste 502 and Spring Festival couplets. Of course not. We need photoresist here. Put the coated wafer in the sun at noon (be careful not to put it everywhere). Then you use some deep water treasures, five wallets and mail back 3 yuan. Large-scale vehicle-mounted magnifying glasses form a lithography array to carry out ultraviolet lithography on circular wafers. Circuit diagram You can manually move the circular chip to complete the route.
After lithography, it is necessary to clean the developed round wafer, and put the cleaned round wafer in the oven to bake and cure the photoresist, or bake it with several egg tarts by the way. Creation and life are correct.
After eating the egg tart and wiping your mouth, you will go to the etching stage. Remember never to use aqua regia. The method of brine electrification etching seems to be good, with low cost and high efficiency. In the process of etching, you should shout at the wafer and rotate the etching carrier at high speed to form ultrasonic vibration in order to remove colloidal impurities.
Burn a little plant ash, then take the etched round crystal to the barber shop, sprinkle plant ash on the round crystal, and let the barber shop do a set of ion ironing for it to remove the gum on the round crystal, thus forming the first loop. Of course, it can't be done at one time. The process of photoresist cleaning, etching and cleaning is repeated about 8 times. The next few times, there are a series of operations such as adding plastic wrap, so I won't go into details. Finally, let the barber do ion implantation.
After ion implantation, the circular wafer has the shape of a transistor, covered with a silicon oxide insulating film, and then punched. Let your brothers and sisters go to work. You can't just enjoy not working, can you? After high-speed dense drilling, the conductive electrode can be pulled out of the hole.
Then cover layer by layer, carve layer by layer, polish layer by layer, connect layer by layer, and finally form a complete round crystal with a complete core. Borrowed a knife from the cake cutter (Lao Huang refused to borrow a knife, which was smoother than him) and began to finely cut round crystals. Cut into cubes like a core. The best is I9, the best is I7, the average is I5, the worst is I3, and the worst is Pentium Celeron. Oh, you're going to be a Mercedes-Benz processor. I think Faraday is better. Let's call it I 10, I8, I6, I4, which is better than Intel. what do you think?
Cut off the processor. Time to pack. Paint some super glue on the IC chip, stick pins on the bottom and a metal shell on the top. Of course, I have to go to the computer after I finish. When you press the start button, a puff of smoke comes out. Don't forget to take a selfie with the smile of the smoke at the moment when the smoke rises as a souvenir.
Billions of wealth finally spent 999997899 yuan to build their own CPU, and the rest went to the electronic city to pat the money on the table: boss, come to a piece of 8700K, let's share it!
The main raw material for producing wood chips is sand. Of course, only with the help of special equipment and technology can we make chips. It can be said that chip manufacturing is turning stone into gold. It is a bit complicated to make a simple cpu out of sand. The main process is as follows:
First, the sand is made into silicon ingots by a special furnace.
Second, cut the silicon ingot into a single silicon wafer with cutting equipment, which is what we usually call a wafer.
Thirdly, coating photoresist and photoetching.
Fourth, etching.
Verb (abbreviation for verb) ion implantation
Six, electroplating
Seven, cutting and packaging
Although the raw sand for making cpu is easy to find, the smelting of high-purity silicon, the IC design of the chip, the production equipment and technology of the chip are very complicated, so if you want to make a simple cpu with sand, you'd better find a chip foundry for OEM.
1. First, prepare 50g of small river sand, remember that the size should be even. The optimum particle size is 0.5-0.2 mm.
2. Wash the river sand and dry it! Remember to dry it in the sun, and the water content should be less than 3%.
3. Prepare a 200mm x 200mm kraft paper, reinforced.
4. Spread the glue evenly on the kraft paper, sprinkle the river sand evenly on the glue, and then dry it!
5. This step is the most critical, and success or failure depends on this step:
Buy a CPU and use sandpaper made of it to polish the logo on it, and then find a correction fluid pen to sign it! A CPU of your own will be done!
6. Next, you can copy papers online and apply for research funding!
1. Extracting silica from sand
2. Reducing silicon dioxide to silicon (chemically pure)
3. Cut the pure silicon into pieces with a kitchen knife (size 0.4cm x 0.4cm x 0.05cm).
4. Draw the layout of 10 transistors on the silicon surface with a laser beam of 0.00 1 nm under the electron microscope (you don't need to draw it yourself, just download a data packet on the Internet, and the computer will execute it by itself, and the data is about 3000G).
5. Then etch with chemical reagent.
6. Make the circuit board and solder the pins.
7. Just cover the shield.
Step 8 plug in boots
9. 1 minute later, the following text appears on the computer:
Lying in the trough, is that okay?

It takes many steps for a processor to be sold for commercial and civil use, such as raw sand (timely), silicon ingot, wafer, lithography (lithography), etching, ion implantation, metal deposition, metal layer, interconnection, wafer testing and cutting, core packaging, grade testing, packaging listing and so on. Of course, since it is self-made and not sold, it can be finished when it comes to core packaging. What test?
Look for a pile of sand first, then you use instruments (what instruments you can buy yourself, assuming you can afford them) to deoxidize, and you can't get them down until the end! Look: Ah, is that shiny thing the legendary silicon? Sand and silicon are deoxidized to 25% in time, which is the basis of semiconductors! So the composition of semiconductor is really simple, but the technical content is a bit too high!
Don't think you can make a processor out of silicon. You must smelt and purify it, so that silicon can be used in semiconductor manufacturing. The scientific name is electronic grade silicon. You can call it Ninja Turtle. You have to purify it repeatedly to get a large crystal composed of electronic grade silicon. The silicon content is as high as 99.99%. Congratulations, this step is completed! As for the melting purifier, please repair it yourself! If you are a fairy, you can use your magic to solve this problem!
This large crystal is cylindrical and weighs about 100 kg. It is heavy, isn't it? Now you have to cut it! Cut this cylindrical crystal horizontally, and each piece is what we often call a wafer. Why are all the wafers we see round? Do you understand now?
Generally, at this point, I estimate that it is almost enough, because these are all things that traditional fabs have to do. Factories that have their own processor production capacity or can do OEM work, such as Samsung, Intel and TSMC, have already started to do it themselves after this step! In the past, those were things with little technical content, which were generally made by other manufacturers. For example, Intel only needs to buy wafers and continue its own processing!
I won't say anything more ... because at this point, I will use the best chip manufacturing equipment-mask aligner! At present, mask aligner generally uses Dutch ASLM company, and Samsung TSMC and Intel are its shareholders, which have the preemptive right, but China can't buy it, so the output is not enough! The price is actually not bad. The cost of a new mask aligner may be less than $200 million, while this factory in the Netherlands produces more than 65,438+00 sets every year!
To be sure, because the subject can't buy mask aligner, so this step can only look at the wafer that he spent a lot of money to buy! Don't lose heart, because wafers need polishing, so they look almost like a perfect round mirror. You can't make a processor, but you can use these wafers as mirrors!
Well, it's actually very simple. In the infinite space, there are countless monkeys. Time is not limited, materials are not limited, it only takes a second for a monkey to hit the sand with a hammer, and then the cpu you want is ready.
In fact, during the Warring States period, someone smashed a radiator with a hammer, which was still bronze.
1. Choose high-quality sand, it must be fine, it must be ground if it is too thick, and it is best to use river sand, the sea sand is salty, and the CPU made is salty;
2. Remember to add black toner as auxiliary material. Please refer to SiO2+2C=Si+2CO (high temperature frying) for specific dosage. Don't use a wooden shovel (I've burned several).
3. Cutting pure silicon wafer (size 0.5nmx0.5nmx0.0 1nm) with superb sword (at least dragon slaying sword) combined with lightning knife method (the fighting skill of each level is worse than that in any large fantasy novel, the minimum standard);
4. Draw the layout of 888 transistors on the surface of the silicon wafer with an eye drill (low-order eye drill, you can do 10 times a day, and practice 1 year later) (you must be calm, people with strong spirit have an advantage, and you can meditate to enhance this ability at ordinary times).
5. Then use a carving knife (all painters know this thing, but it's not Taobao's, like in 9.9) to etch the surface with an etching knife method.
6. Find a small square film (Taobao has a custom-made, choose a good quality shop, some are not up to standard and easy to paste) as a circuit board, and solder the pins (it is important to practice this welding several times);
7. Arrange shielding cover (Tai Chi II array method to prevent information leakage and isolate other injuries at the same time) and put it away;
8. Of course, other computer accessories are needed at this time, which are not rare and easy to handle (and beware of foreign garbage, which is not stable to use);
9. Install the system (there are free tutorials online) (buy a fool to install a USB flash drive, of course, if you go to the celestial world, it will be more perfect to install it with your mind);
10, after 0.8 seconds, the computer will usually prompt the following words: Congratulations, your computer beat 99.99% of the computers, won the title of magic machine, and perfectly ran all the major cosmic masterpieces.
1 1. From then on, I have a machine in my hand, which is available all over the world! I used to say 666!
Accidentally revealed such a powerful method, but this is the production process of God U, is it simple? You can make your own decisions, and you can release water at every step, but this scale depends on your own grasp.
You can't do such a simple thing? !
Step 1: Prepare clean sand, white sand and yellow sand!
Step 2: Prepare a clean desktop.
Step 3: The most important step is to start making. Grab the yellow sand with your right hand and put your left hand behind your back! Take the three letters of CPU as the track on the desktop and sprinkle sand evenly!
Step 4: Take photos and send friends.
1. Write three letters of CPU on white paper with a thick pen.
2. Paint these three letters with glue, and be careful not to paint them where there are no words.
3. Sprinkle sand on the glue.
When the glue is dry, you are done! The simplest CPU making method in the whole network!
It depends on what equipment you use. A basic MOS transistor, the channel of source and drain, is generally micron-level, and general equipment can't do it.
Maybe you think, you can make it bigger. But this is impossible, and the channel length is too large for the device to work at all.
In addition, the chip manufacturing process requires extremely high environmental requirements, such as dust-free and static-free, and the initial purity of silicon ingots should reach 9 nines, which is 99.999%. What did you say?/Sorry?
