How is silicon made into a CPU?

Simply put, it is with a laser.

This is a complex issue

Wafers are made from silicon ingots that are shaped into a perfect cylinder and then cut into sheets.

Wafers are not made by the CPU, but are used to make the CPU.

Modern CPUs are made of silicon, and the purity of silicon materials is extremely high in order to make CPUs

It will be chemically purified to the point that there are almost no impurities, and it will have to be converted into silicon crystals.

The raw silicon will be melted and placed into a huge quartz furnace. At this point, a seed is placed in the furnace so that the silicon crystal grows around the seed until it becomes a near-perfect monocrystalline silicon.

The silicon ingots are fabricated and shaped into a perfect cylinder, which is then cut into sheets, called wafers. Wafers are actually used for CPU manufacturing. Generally speaking, the thinner the wafer is cut, the more finished CPU products can be made with the same amount of silicon material.

Why do you say so much? To put it simply, it is made of sand (monocrystalline silicon (sand) with a high degree of purity).

Silicon is used for CPUs because it has so many advantages and disadvantages that can be overcome. Although germanium also has advantages (such as turn-on voltage and carrier mobility), it has several disadvantages that are difficult to overcome.

If you ask what the CPU is made of, everyone will easily give the answer - silicon. This is true, but what about silicon from? In fact, it's the most inconspicuous sand.

It's hard to imagine that the **expensive, complex, powerful, and mysterious CPU should come from that worthless sand.

Of course, there is a complex manufacturing process that must go through in between. However, it is not just a handful of sand that can be used as a raw material, it must be carefully selected to extract the purest silicon raw materials. Imagine if you made a CPU from the cheapest and most abundant raw materials, the quality of the finished product, and you could still use a high-performance processor like today.

The material of the chip is silicon.

But it's not just silicon.

Silicon is used as a material because silicon is a semiconductor.

Semiconductors mean that an electric current conducts electricity from one side to the other.

The reverse does not conduct electricity.

This excellent property is very suitable for mounting integrated circuits on it.

Integrated circuits are composed of various logic circuits.

The so-called logic circuit is the AND gate.

or doors. NAND Gate.

These circuits allow the computer to:

Run. So.

Computers are silicon that contains integrated circuits.

Pure hand-played. Hope.

There are roughly three ways to improve CPU performance:

1. Design more complex circuits, so the performance is higher.

2. Design a new type of circuit, so the performance is improved.

3. Find new materials to make CPU, so the performance will also be improved, these three methods are constantly advancing and integrating under the current technical conditions, so the performance of CPU will continue to improve. Batteries, which are related to the field of materials engineering, must be supported by basic physics research, which is not easy to break through. It is impossible to make progress in the field of batteries without the discovery or invention of new materials.

Upstairs is right, Moore's Law still drives the development of the entire hardware industry, but don't forget that the scalability and extensibility of technology are constantly improving with the progress of the times. Take the current cloud computing technology as an example, it is also composed of many parts, and Google's cloud computing center has millions of servers.

In other words, our direction can already be determined, but our results are constantly complex, because although this task has been theoretically derived by predecessors, the result will take many generations to complete.

Hehe, what do you say!!

The basic architecture will not change, and there will only be core, instruction set, cache, frequency, process, and integration.

CPU chip technology comparable to atomic bomb technology How many countries in the world can build it?

CPU technology is one of the world's top technologies, and it's not as easy as you say.

The chip is like a master controller, he is to input through the input device, after the input identification, calculation, shunt, and then through the output device display, and then you see the information and then through the input device input, input identification, calculation, shunt, and then through the output device display, is such a principle, silicon is used because of the characteristics of this material conductivity is good, conduction can be at the same time in the conduction of good shunt, easy to form a good control branch after manufacturing, the computer through the power to make the manufacture The components are activated like flowing water, the memory begins to transport information through the memory space, the hard disk begins to store generations, the graphics card begins to display the image on the screen through imaging technology, and the sound card begins to convert the input file information into sound through the output device**,
