Galaxy Technology Empire

Domestic semiconductor professional website, on November 9.

A research report on the world's silicon wafer industry was released, which immediately broke the Internet.

The bib also forwarded this article.

"The New Pattern of Silicon Wafers in the World", as of the release date of the research report, the silicon wafers of Neutron Star Company, a subsidiary of Galaxy Technology, have occupied 87% of the world's silicon wafer supply market.

The five giants including Shin-Etsu, Silitronic, and LG Chem, which previously held 98% of the silicon wafer supply market, have seen their overall market share drop to about 13%, and have been forcibly acquired by various chip manufacturing companies, and are currently reduced to low-end silicon wafer suppliers.

Congratulations to Neutron Star for becoming the world's number one company in the silicon wafer industry.

Materials Research Institute of Galaxy Technology.

Li Xiang and others have spent almost no time sleeping or eating in the past few months, because the invention of C31 fullerene gave Galaxy Technology atomic-level processing capabilities.

What is the accuracy of lathes in the world today?

Turning, milling, planing, grinding, drilling, and 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.

For example: turning precision is generally IT8-IT7, and surface roughness is 1.6-0.8 microns. Using finely ground diamond turning tools on high-precision lathes to finish turning non-ferrous metal parts at high speed can achieve a processing accuracy of IT7-IT5 and a surface roughness of Rα0.04-0.01 microns. This kind of turning is called "mirror turning".

Machining accuracy is mainly used to characterize the fineness of produced products and is a term used to evaluate the geometric parameters of the machined surface.

The standard for measuring machining accuracy is tolerance level. There are 20 levels from IT01, IT0, IT1, IT2, IT3 to IT18. Among them, IT01 represents the highest machining accuracy of the part, and IT18 represents the lowest machining accuracy of the part.

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

Product parts require different processing accuracy depending on their functions, and the selected processing forms and processing techniques are also different.

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

The surface roughness of precision grinding is 0.16-0.04 microns; the surface roughness of ultra-precision grinding is 0.04-0.01 microns; the surface roughness of mirror grinding can reach less than 0.01 microns.

In other words, the highest accuracy that humans can currently achieve is around 10 nanometers.

The problem is that this extreme precision is difficult to achieve in machining under normal circumstances, otherwise the photolithography machine would not be chosen in the chip process.

However, Galaxy Technology’s Materials Research Institute is currently able to complete part of the nano-level finishing.

By increasing the machining accuracy to the limit of 1 nanometer, 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 can be about 400 picometers, that is About 0.4 nanometers.

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

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

In terms of graphene production, Galaxy Technology can directly transport molecules to complete the production of graphene.

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

In the past few months, Galaxy Technology's Materials Research Institute has successfully applied for more than 2,000 patents on materials alone.

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

Huang Haojie held a piece of graphene the size of a mobile phone screen. This is a translucent graphene plate with a thickness of 100 nanometers.

This graphene plate is made through the atomic transport ability of C31. It is 100 nanometers thick and has a total of 250 layers of graphene.

I saw him directly kneading the graphene plate into a ball of paper, and as soon as I let it go, it instantly returned to its original shape.

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

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

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 flaws.

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 capacity is three times that of a silicon solar panel.

But there is a problem with graphene solar panels, that is, how to transport the electricity out of the graphene solar panels.

"Boss, we have completed the mass production process design of carbon fiber. Can we prepare for mass production?" Wen Du, deputy director of the Materials Research Institute, is responsible for technology application transformation.

"Give me the design plan and I will make arrangements." Huang Junjie thought for a while and ordered.

Wen Du quickly went to get the carbon fiber mass production plan.

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

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

"Can!"

"no problem."

"normal."

"Then let me get straight to the point. The main reason for this meeting today is that the carbon fiber from the Materials Research Institute can be mass-produced. Next, Neutron Star Company will mass-produce carbon fiber materials." After Huang Haojie finished speaking, he handed the planning document aside. Du Wei.

"The reason for calling you here is very simple. Once the materials are available, they 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 advantages of carbon fiber are its light weight and high strength. Its weight is only equivalent to 20% to 30% of steel, but its hardness is more than 10 times that of steel.

Therefore, the use of carbon fiber materials in automobile manufacturing can make automobiles lighter, achieve breakthrough progress, and bring social benefits of energy saving.

The generator rated power of wind turbines in the world is getting larger and larger, and the size of the corresponding wind turbine blades is also getting larger and larger.

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

In addition to being used in aerospace, national defense and sporting goods, carbon fiber is also being used in new 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, ocean development, new energy and other fields.

It can be said that it is widely used, especially in almost all the companies under Galaxy Technology. The vertical agriculture building that Planet Group is building for Fengdu Group can use carbon fiber to extend its service life.

Various companies were arranged to prepare carbon fiber applications.

Although other materials can be prepared, there are still many problems in practical applications that need to be solved and improved by Galaxy Technology.

Huang Haojie is preparing for tomorrow’s press conference of the 5-nanometer chip production line.
