The domestic semiconductor professional website, on November 11th.

Published a research report on the world's silicon wafer industry, blowing up the Internet at once.

Scarf also forwarded this article.

"New pattern of silicon wafers in the world", as of the release date of the research report, the silicon wafers of Neutronstar, a subsidiary of Yinhe Technology, have occupied 87% of the world's silicon wafer supply market.

The five giants, including Shin-Etsu, Silitronic, and LG Chem, which had been occupying 98% of the silicon wafer supply market before, had an overall market share of about 13%, and were forcibly acquired by various chip manufacturers, and are currently reduced to low-end silicon wafer suppliers.

Congratulations to NeutronStar for being number one in the silicon wafer industry.

Materials Research Institute of Galaxy Technology.

Li Xiang and others have almost forgotten to sleep and eat in the past few months, because the invention of C31 fullerene has given Yinhe Technology the ability to process at the atomic level.

What is the accuracy of lathes in the world now?
Turning, milling, planing, grinding, drilling, boring, the highest precision of these machine tools and the tolerance levels that can be achieved by various processing methods are generally between microns and nanometers.

例如：车削加工精度一般为IT8—IT7，表面粗糙度为1.6—0.8微米。在高精度车床上用精细修研的金刚石车刀高速精车有色金属件，可使加工精度达到IT7—IT5，表面粗糙度为Rα0.04—0.01微米，这种车削称为“镜面车削“。

Machining accuracy is mainly used to characterize the fineness of the produced product, and it is a term for evaluating the geometric parameters of the machined surface.

The standard for measuring the machining accuracy is the tolerance level. There are 01 tolerance levels from IT0, IT1, IT2, IT3, IT18 to IT20. Among them, IT01 indicates the highest machining accuracy of the part, and IT18 indicates the lowest machining accuracy of the part.

General factory and mining machinery belongs to IT7 level, and general agricultural machinery belongs to IT8 level.

According to the different functions of the product parts, the processing precision that needs to be achieved is different, and the selected processing form and processing technology are also different.

Among them, grinding is usually used for semi-finishing and finishing, the precision can reach IT8-IT5 or even higher, and the surface roughness is generally 1.25-0.16 microns.

精密磨削表面粗糙度为0.16—0.04微米；超精密磨削表面粗糙度为0.04—0.01微米；镜面磨削表面粗糙度可达0.01微米以下。

That is to say, the highest precision that humans can achieve at present is around 10 nanometers.

The problem is that the ultimate precision is difficult to achieve by mechanical processing under normal circumstances, otherwise the method of lithography machine would not be chosen in the chip process.

However, the Materials Research Institute of Yinhe Technology has been able to complete part of the nano-level finishing.

Raise the machining accuracy to the limit of 1 nanometer, and the atomic limit can be reached in the future. For example, the radius of a carbon atom is 91 picometers, and the diameter is 182 picometers. Adding the atomic surface tension, the processing limit is about 400 picometers, that is, About 0.4 nanometers.

If you still want to continue to improve the accuracy, you can only consider breaking the atomic structure and performing neutron and proton modification.

If the improvement of finishing alone is not enough to bring about a qualitative change in Galaxy Technology, then the atom transport ability of C31 fullerene endows Galaxy Technology with another effect, the ability to arrange and combine atoms, which will directly make Galaxy Technology's materials science and finishing. qualitative change.

For example, in terms of graphene production, Yinhe Technology can directly complete the production of graphene by transporting molecules.

What is graphene? Simply put, it is a single layer of graphite, a two-dimensional flat material.

In the past few months, Yinhe Technology's Materials Research Institute has successfully applied for more than [-] patents on materials alone.

Among them, carbon materials such as graphene, carbon fiber, and artificial diamond can be said to have advanced by leaps and bounds.

Huang Haojie holds a piece of graphene the size of a mobile phone screen, which is a translucent graphene plate with a thickness of 100 nanometers.

This graphene plate is manufactured through the atomic transport ability of C31, with a thickness of 100 nanometers and 250 layers of graphene stacked on it.

I saw that he directly squeezed the graphene plate into a ball of paper, and it returned to its original shape in an instant after letting go.

It is not so much a graphene plate as a graphene paper or film.

In fact, graphene is widely used, including graphene batteries, graphene solar power generation, graphene semiconductors, graphene seawater desalination and so on.

The reason why there is no large-scale application at present is that the production technology is not good enough, resulting in high cost;

The second is that the material performance is very good, but there are technical defects.

For example, in terms of graphene solar power generation, a photon bombarding a silicon atom can only produce one electron, but bombarding a carbon atom can produce three electrons, which means that the power generation is three times that of a silicon solar panel.

But graphene solar panels have a difficult problem, that is how to transport the electrical energy from the graphene solar panels.

"Boss, we have completed the large-scale production process design of carbon fiber, can we prepare for mass production?" Wen Du, deputy director of the Materials Research Institute, is in charge of technology application transformation.

"Give me the design plan, and I'll arrange it." Huang Haojie thought for a while and ordered.

Wen Du hurried to get the carbon fiber mass production plan.

After Huang Haojie took over the plan, he summoned Du Wei, the president of Neutron Star Materials Company, and asked Pang Dayi from Planet Group, Fang Shengjie from Raytheon Group, and Wen Weiping from The Paper Group to conduct a video conference.

"Ahem, can you hear me clearly?" Huang Haojie patted the microphone.

"can!"

"no problem."

"normal."

"Then I'll get straight to the point. Today's meeting is mainly because the material research institute's carbon fiber can be mass-produced. Next, Neutron Star will mass-produce carbon fiber materials." After finishing speaking, Huang Haojie handed the plan to the side. of Du Wei.

"The reason for calling you here is very simple. If there is a material, it must be applied on a large scale. Carbon fiber can be used in wind wheels, electric vehicle bodies and parts, electric vehicle parts, and building materials."

Wen Weiping and others immediately understood the usefulness of carbon fiber for their products.

As an automotive material, the biggest advantage of carbon fiber is its light weight and high strength. Its weight is only 20% to 30% of that of steel, but its hardness is more than 10 times that of steel.

Therefore, the use of carbon fiber materials in automobile manufacturing can reduce the weight of automobiles, make breakthroughs, and bring social benefits of energy saving.

The rated power of generators of wind power generating sets in the world is getting bigger and bigger, and the size of fan blades corresponding to it is also getting bigger and bigger.

In order to reduce the deformation of the blade, carbon fiber is used in some parts of the main force parts such as bearings and blades to supplement its rigidity.

In addition to being used in aerospace, national defense and sporting goods, carbon fiber is also being used in new carbon fiber markets such as automotive components, wind power blades, building reinforcement materials, reinforced plastics, and drilling platforms.

In addition, it is also used in pressure vessels, medical equipment, marine development, new energy and other fields.

It can be said that it has a wide range of applications, especially in almost all the companies under Galaxy Technology. The vertical farming building that Planet Group is building for Fengdu Group can use carbon fiber to prolong its service life.

Arrangements were made for various companies to prepare carbon fiber applications.

As for other materials, although they can be prepared, there are still many problems in practical application, which need to be solved and perfected by Yinhe Technology.

Huang Haojie is preparing for the press conference of tomorrow's 5nm chip production line.
