The rise of nanometers

Hongcao Town, Meicheng District, Shantou.

Not far from the headquarters of Suiren Company and the scientific research area, less than 2 kilometers away, a semiconductor base covering an area of ​​more than 5,000 acres has been leveled.

A large number of concrete frame and steel structure factory buildings have been built in one-third of the area. Pengcheng Central Inspection Company and several other engineering contracting companies are starting construction step by step.

Jiang Mingzhang of CCIC specializes in working with Suiren Company. Last year and this year, he won 1.3 billion contracts for the construction of a large number of instruments, equipment and laboratories. These are all money.

Moreover, Suiren Company's prices are relatively good, and it has no arrears on project payments. It is simply the dream partner of engineering contracting companies.

CCIC has asked Jiang Mingzhang to take charge of the semiconductor base that is currently under construction. He must satisfy Suiren Company.

This semiconductor base is called Dragon Totem Semiconductor Base.

The president of Long Totem Company is Zhang Weixin, the vice president of the head office, and the technical executive officer is Zhang Jingjian of the Semiconductor Microcircuit Laboratory.

Zhang Weixin, Jiang Mingzhang and others discussed the project and equipment, and then came to one of the factory buildings that was already in use.

In a high-level dust-free workshop.

Engineers, technicians, and researchers wearing full-body protective clothing and gas helmets are installing and debugging a chip production line.

"Jingjian, Mr. Huang and Mr. Lin have approved the glass disc project of the Scientific Research Department, and they will be busy next."

Putting down the tablet, Zhang Jingjian smiled and said, "It's good to be busy! I'm afraid I'm too busy."

Of course, it's better to be busy when running a company. It's not a good thing if you have nothing to do all day long.

"The production line of glass optical discs needs your follow-up. I have communicated with Mr. Du from Snail. Their industrial design center will fully cooperate with you." Zhang Weixin said as he walked.

"no problem."

…

After reporting to the headquarters, newcomers such as Wang Zhiyuan and Lu Qifu were arranged to a factory building in the semiconductor base for training and adaptability.

I just finished a class and came to the canteen in Pubian Town next door.

"Why do I feel like I'm in a pyramid scheme?" Lu Qifu joked while eating rice.

Wang Zhiyuan picked up a braised beef slice and said, "I guess it's because I'm afraid of infiltration by external forces, and a lot of the information given by the company is not made up of nothing. When I went to the United States as an exchange student, what I saw was indeed similar to what the company said."

"Yeah?"

Wang Zhiyuan nodded: "The company does not demonize foreign countries, and many of the investigations it provides are very objective. The world outside the wall is not only rich and glamorous, but also darkness."

"It seems that a lot of what we have seen before are beautified scenery through filters." Lu Qifu was a little disappointed, and also felt a little inexplicable.

Wang Zhiyuan felt even more profoundly, because he had experienced the smell of urine in the New York subway, had seen the decay of Detroit, and even witnessed with his own eyes the bloody mess falling from the sky on Wall Street.

After being summarized by the company's instructor, he gained a more intuitive and comprehensive understanding of the Western world.

"Perhaps the company is right to give up its illusions and prepare to fight. The enemy has been spying on the fruits inside the wall." After Wang Zhiyuan finished speaking, he took another sip of the pork rib soup.

Lu Qifu changed the subject: "Zhiyuan, how was your group's internship?"

"It seems to be designing a battery control chip, but I don't know much about it. We won't know the details until our internship period is over."

Lu Qifu said thoughtfully: "It seems that the company is indeed developing its own chips, but it doesn't know how to solve the problem of the lithography machine."

"Lithography machine? It's difficult! Microelectronics seems to have a project in Shanghai, but the level is worrying. Let alone keep up with ASML, even if it is the level of Nikon and Canon, we can't reach it." Wang Zhiyuan is a little worried.

…

July 21st.

The industrial design center of Snail Industry dispatched a team of more than fifty professional engineers, plus the Miao Guozhong team of the Glass Disc Laboratory and engineers from Long Totem Company.

Began to design a production line for mass production based on the technology of glass optical discs.

The main technical difficulty in the mass production process of glass optical discs is the accurate arrangement of the heterosilicon 9. The solution proposed by Miao Guozhong's team is to use the nanowire masking method.

The nanowire masking method first produces a glass film, then ion-deposits a layer of heterosilicon 9 on the glass film, and uses the processed aluminum nanonet on the other side to cover the glass film. Finally, a layer of glass film is added, and the silicon nanoparticles are passed through the The coating is cured and a glass disc is finished.

The grid of the aluminum nanomesh will expose the 9 layers of heterosilicon underneath to form grid points, and the laser irradiation of high-intensity ultraviolet light will be reflected by the aluminum nanomesh, thereby achieving a blocking effect.

The glass optical disc produced by this method is not only suitable for large-scale mass production, but the data points formed by the grid points are also very accurate.

Because the aluminum nanomesh is the key to determining the accuracy of the grid points, the 9 layers of heterosilicon do not determine the accuracy. If you really have to assemble the data points one by one, not only will the process be very difficult, but it will also lead to low accuracy and exploding costs. rise.

Using the masking method to produce glass optical discs requires supporting equipment, including ion deposition machines, aluminum nanowire synthesis machines, aluminum nanomesh weaving machines, and silicon nanocoating machines.

Suiren Company can produce these production line equipment by itself, as long as it places an order with Snail Industry.

As for deep ultraviolet burners, the production line is already being laid out. At the same time, engineers at the Industrial Product Design Center are also compressing product costs while ensuring product quality.

If a deep ultraviolet recorder priced at RMB 50,000 to RMB 60,000 is to be used on a large scale by ordinary consumers, it must reduce costs and control the price to less than RMB 10,000 before it can be reluctantly accepted by consumers.

The cost of a reader that also costs more than 800 yuan must be further reduced.

At this stage, the production process of glass optical discs has matured, but the remaining issue is cost.

More than a week later, all the equipment of the first glass disc production line was installed and entered the trial production stage.

On the production line, glass discs with a side length of 1.2 decimeters come off the assembly line. The smooth glass mirror is almost a transparent glass piece.

If you put these glass discs among a pile of ordinary glass, you really can't tell that this thing is a data memory with a storage capacity of 9200G.

Miao Guozhong immediately took his people, selected a hundred of them, and sent them for quality inspection.

The test results are very good. The quality of the glass disc is in line with their design expectations. Based on the arrangement of data points, the yield rate reaches more than 99.9999%.

Even if there is an abnormal arrangement of data points in a small area of ​​the glass disc, the area can be shielded and an abnormal area signal feedback can be burned in the directory area so that the recorder and reader can detect the abnormality during the recording and reading process. , automatically skip the abnormal area.

Of course, Dragon Totem has no intention of selling defective products. Glass discs found in abnormal areas are usually scrapped directly instead of entering the market.

After passing quality inspection, most of the first batch of trial-produced glass discs were sent to Time Information to upgrade the cold standby database. A small part was sent to the Ministry of Industry and Information Technology in preparation for applying for a birth certificate.

Happy New Year and good luck in the Year of the Ox!
