Chapter 1365 Historical Moments
What Duan Yun also needs to break through is the lithography machine technology, and among them.

Top-level light source, high-precision lens and precision instrument manufacturing technology are the three core technologies of EUV lithography machine. The light source of ASML comes from the acquired subsidiary Cymer; the lens comes from deeply bound Zeiss; the precision instrument has its own many years of experience Experience and patent accumulation.

In fact, from the perspective of the development of the chip industry in later generations, domestic lithography machines have made major breakthroughs in terms of light sources and alignment tables of lithography machines, reaching the international advanced level. China's extreme ultraviolet light is also quite powerful. Therefore, light sources and workbenches are not the most important factors restricting domestic lithography machines.

What really restricts the development of domestic lithography machines is the lens of the lithography machine. ASML can become the leader in the field of lithography machines, and its core technology is the optical lens from Zeiss.

German Zeiss is an old-fashioned optical manufacturer, which began to produce camera lenses as early as 1890. The influence of this company in the industry is not only to sell camera lenses, Zeiss is also engaged in the manufacture of high-end lithography high-precision lenses, the Dutch company ASML The lithography machines manufactured basically use Zeiss lenses.

In the early years, Japan’s Nikon and Canon could also produce technologically advanced lithography machines with a good foundation in optical technology. However, after entering the 90s, with the continuous improvement of chip manufacturing technology, Nikon and Canon have tried to do higher. Lithography machine lenses, but all failed, so we had to give up. On this earth, only German Zeiss lenses can produce high-precision magnifying glasses.

How high the requirements of the lithography machine on the lens can be seen from its technical structure.

The lens located in the center of the lithography machine is composed of more than 20 large lenses connected in series. The lens must be made of high-purity light-transmitting material and high-quality polishing. It will take at least several decades for the material of this mirror surface to be uniform. Hundred years of technology accumulation.

The same lens is polished by different workers, and the finish is 10 times different.

The workers who polish lenses in the Zeiss company in Germany have three generations of grandparents in the same position in the same company.

If the surface of the optical lens of the ASML lithography machine is compared to a German territory, then the error of the buildings on it cannot be higher than two centimeters. It can be seen that the precision of this optical lens has reached an incredible level.

Now that Zeiss is controlled by ASML, it is impossible for Duan Yun to obtain high-precision lithography machine lenses from Zeiss. The only thing he can do is to support the research and development of domestic optical lenses.

Through understanding, Duan Yun learned that there are three domestic optical companies that have settled in the Shenzhen Science and Technology Park this time, two from BJ and one from Shanghai.

These optical research institutes were the first to study eye lenses. No matter in terms of corporate background or technical strength, they are far behind Zeiss, Nikon, Canon and other international manufacturers, and there are many technical bottlenecks that need to be broken through.

But good for the 80s.The technology of lithography machines is far less complicated than the EUV lithography machines of the later generations after 2000. If Duan Yun can maintain capital investment in these companies for a long time, he will have the opportunity to catch up with these international giants.

Once the optical lens of the lithography machine is broken through, the domestic lithography machine manufacturing has broken through the biggest technical bottleneck, and the localization of advanced lithography machines will become a reality.

As a series of lights flashed on the console, the NAND flash chip officially entered the trial production stage. Everyone present held their breath, and Duan Yun's face also looked very solemn.

Duan Yun has been waiting for this day for two years. If the trial production of NAND chips is successful, it will be a historic day for him and the entire national chip industry, and China's chip industry will also open a new chapter.

There was a hissing sound from the lithography machine, and it took only 3 minutes for the first wafer to be processed. It passed through the conveyor belt and entered the follow-up procedure. Once the finished product was tested successfully, it meant that the first NAND chip in the world was on the market. China was born.

At this time, Huang Lingyi couldn't restrain the excitement in her heart, and her body began to tremble slightly.

When all 20 wafers were processed, Duan Yun and others left Area C and came to the testing room located in Area A.

"Come out, come out!" Seeing the chip test results appear on the screen of the testing instrument, Jiang Mingwei shouted excitedly.

"The qualified rate of the finished product is 84%. All the chips are in good condition and there is no problem." At this time, the staff in charge of the chip inspection handed an inspection report to Duan Yun, and said excitedly.

"Papa papa!" Applause erupted at the scene, even though everyone was still wearing dust-proof gloves, the applause was still very enthusiastic.

"Great!"

"congratulations!"

At this moment, several people around finally showed smiles on their faces, and congratulated each other. Huang Lingyi even took the initiative to hug several people present.

"I now officially announce that the trial production of the NAND flash memory chip developed by Tianyin Group has been successful!" At this time, Duan Yun's voice was a bit high-pitched, and he continued: "Today's success is inseparable from everyone's efforts. For Tianyin Group and even China's chip industry, this is a memorable and historic day, and here I would like to express my deep gratitude to all those involved in chip research and development!"

When Duan Yun said this, he bowed to everyone.

At this moment, Duan Yun's heart was extremely excited, and a boulder that had been pressing on his heart for a long time was finally let go.

It can be said that the birth of this chip is the biggest achievement he has made since his rebirth came to this world, and the products he developed before, at best, only helped him earn a lot of money, far less than what this chip brought. of great value.

"Manager Duan, we should be thankful. Without you, we would not have achieved this year's results." At this time, Huang Lingyi said to Duan Yun excitedly.

"Yeah, I really didn't expect Tianyin Group to be so powerful and able to make such a good integrated circuit. A private company can do something that the country can't do. It's an eye-opener for me." Jiang Mingwei said Time followed suit.

It is true that Jiang Mingwei was thinking of making money when he joined Tianyin Group, but he also really wanted to make a career and contribute to the country's integrated circuit industry. This has always been his wish.

If he still doubted Duan Yun's ability and the strength of Tianyin Group at the beginning, then such doubts have completely disappeared now. In his opinion, Tianyin Group is indeed a company full of miracles. Compared with the national scientific research units, the strength It's even more than that...
