Countercurrent 1982

Chapter 1343 Major Breakthrough
Just when his wife Cheng Qingyan started planning to enter the domestic real estate industry, Duan Yun finally got a great news from the chip research and development team, that is, the team led by Wang Lingyi has initially completed the design of the NAND flash memory chip, and the next step is to prepare the photolithography mask. Diaphragm, and then trial production.

At present, Tianyin Group cannot produce masks. The flash memory chip mask used before was provided by Toshiba, Japan, and the imitation 6052 chip mask used later was Huang Lingyi’s old company, the Institute of Microelectronics, Chinese Academy of Sciences. The production cost a total of more than 20 yuan.

Unlike the nano-level chip masks of later generations, the production of micron-level chip masks in the 80s was not difficult.

The first generation of masks appeared in the 1s and were hand-engraved red films, which have now been eliminated.

The second-generation mask is the Feilin mask, which was born in the 2s and is still used in some industries in a small range, such as pcb, fpc and other industries.

Today, chip companies generally use the fifth-generation mask, which is divided into soda mask and quartz mask, which were born in the 5s.

China's mask manufacturing is mainly concentrated in a few enterprises and some scientific research institutes, including the Institute of Microelectronics of the Chinese Academy of Sciences, the Institute of Semiconductors of the Chinese Academy of Sciences, the 13th Institute of Electronic Science and Education, Wuxi Zhongwei Photomask, the 55th Institute of Electronic Technology, and the Chengdu Institute of Optoelectronics of the Chinese Academy of Sciences.

Among these enterprises, Huang Lingyi's former owner, the Institute of Microelectronics of the Chinese Academy of Sciences, has the most advanced mask production technology in China. They can now produce optical masks with a resolution of 1.2 microns, which is very close to the international advanced level.

In the early years, these high-tech technologies were basically closed to private companies. However, in recent years, various departments of the Chinese Academy of Sciences have also begun to come down. In Zhongguancun alone, there are more than 40 companies affiliated with the Chinese Academy of Sciences, including optical masks. make.

Huang Lingyi's project team developed a NAND flash memory chip with a process of less than three microns. Domestic companies are fully capable of producing optical masks for this chip.

While taking Huang Lingyi to BJ with the parameters of the newly developed NAND flash memory chip to make optical masks, Duan Yun also began to make preparations to register product patents for this newly developed NAND flash memory chip at home and abroad.

As early as a few years ago, Duan Yun had already employed several lawyers from Shekou Law Firm to set up the company's legal department. Over the years, several lawyers in the legal department have been formulating various labor contracts, product transaction contracts and Various legal consultations have played a very important role, and this time, Duan Yun plans to subdivide the legal department and arrange several people to specialize in product patent applications.

In recent years, the cost of international patent application has been getting higher and higher. It takes at least 2 US dollars to apply for a single product patent in a country. If you want to speed up the patent review process, the price must be increased by at least 5 times, which is 10 US dollars. It takes at least one month for a patent application to be successful.

But in any case, as long as the patent can be registered before Hitachi of Japan developed the NAND flash memory chip in 1989, Duanyun will win a major victory.

At present, the storage capacity of Toshiba's Flash memory chip produced by Duan Yun is 512KB, and this is a newly developed NAND flash memory chip with a storage capacity of 1MB, which not only doubles the storage capacity, but also reads and writes faster than NOR. The chip is much faster, and it is precisely because of this that after the appearance of the NAND chip, it quickly replaced the NOR flash memory chip and became the highest-selling storage chip in the world at that time.

However, this three-micron process NAND flash memory chip is only a transitional product for Duan Yun. His purpose is to occupy the patent rights of this product in advance. In the next step, he will arrange for Huang Lingyi's team to develop a chip based on the one-micron process. technology, a NAND flash memory chip with a storage capacity of 2MB.

However, if you want to develop and produce chips with a micron process, it is not enough to rely on a few advanced ASML lithography machines. If you cannot introduce advanced foreign product equipment, then Duan Yun still needs to solve many technical thresholds, and Next, whether the Ministry of Machinery and Electronics Industry will send a "national team" to Shenzhen Science and Technology Park, and realize the seamless connection between R&D institutions and their Tianyin Group's product technology is the key to whether domestic one-micron process chips can be produced.

But whether this matter can be finally implemented, Duan Yun still needs to wait patiently.

There is no news from the Shenzhen Science and Technology Park, but the sales volume of Tianyin Group's products this month has reached a record high.

Under the overwhelming publicity of advertisements, the sales of Tianyin disc video recorders and repeaters continued to rise, and Tianyin brand learning machines completely detonated the market, reaching a state of short supply.

The 35 learning machines that were put on the market in advance were all sold out in less than a month. More than 200 dealers across the country asked the head office to increase the supply. It drove directly to the entrance of Tianyin Electronics Factory, so that many products had already been pulled away by suppliers as soon as they came off the production line. No less.

A large number of orders prompted Duan Yun to continuously outsource products in order to increase production. More than 20 holding companies in the group have all reached the upper limit of production capacity, and the daily production of learning machines is as high as 3 units. Reseller Membership Requirements.

Not only that, Tianyin Group has also supported nearly half of the enterprises in the Upper Industrial Zone and Bagualing Industrial Zone. Because the demand for video recorders and learning machine cassettes is also very large, many manufacturers who originally assembled radios, tape recorders and other electronic products rushed to Turned to the production of cassettes for video recorders and learning machines. Because of the tight construction schedule and the large number of orders, the Shangbu Industrial Zone and Bagualing Industrial Zone have almost become cities that never sleep. Standing on the mountain in the evening, the lights are bright, very spectacular.

And Duan Yun's Tianyin chip factory has also entered a state of full production. After the newly added 4 photolithography machines were put into use, the daily chip production has doubled from the previous 2 pieces to more than 4 pieces. If other follow-up equipment is installed in place, after the two new production lines are put into production, the maximum daily chip output will reach about 7 pieces, and the annual output will reach 2 million pieces, which is almost twice the total chip production in China last year.

The booming sales of Tianyin Group's products also led to a sudden increase in electricity consumption in the Shenzhen Industrial Zone. The peak period of electricity consumption has more than tripled. In order to ensure that there will be no problems with the power supply facilities, the SZ Municipal Government has also specially An emergency team was set up to direct a large number of electric power workers to conduct 24-hour line inspections. At the same time, the plan to start the third phase of the Shekou Power Plant has been included in the schedule. It is planned to build a new power supply network within two years...
