Life 1984

Li Yunhai and Li Juan came to Ji Wenshu's office.

Professor Ni and others are here.

As soon as Ji Wenshu saw Li Yunhai, she shouted excitedly: "Mr. Li! I succeeded! I finally lived up to your expectations. I developed an immersion lithography machine!"

Li Yunhai laughed and said, "Congratulations, President Ji! I've said it before, you will definitely succeed!"

Everyone applauded and congratulated Ji Wenshu.

Ji Wenshu couldn't help herself, she held her face with her hands and shed tears of happiness.

It took so many years to successfully develop this product. Only the people involved can understand the bitterness and pain involved.

Li Yunhai patted Ji Wenshu's shoulder gently and said with a smile: "Don't cry, it's a happy day! Tonight, we will have a dinner together! By the way, President Ji, if this project is successful, I will reward you and your team with 10 million in cash!"

The whole audience exclaimed "Wow" and then cheered loudly.

Ji Wenshu really stopped crying and burst into laughter: "Ten million? Isn't that too much?"

Li Yunhai said: "You think it's too much? Then I'll cut it in half?"

Ji Wenshu said quickly, "No, no, no, it's not just me who gets it, everyone has to share! Mr. Li, I'll take you to see the machine."

Li Yunhai nodded.

We came to the laboratory.

The immersion lithography machine invented now has only been successful in the laboratory. It will take some time to turn this technology into a project that can be mass-produced.

The principle of immersion lithography is to add a layer of water above the wafer and use a deep purple light source.

When deep ultraviolet light is refracted through water, the 193 nm wavelength becomes 134 nm, thereby improving the accuracy of lithography.

Except for the immersion system, the other structures are similar to those of ordinary non-immersion lithography machines.

The former Sihai Group already possessed relevant lithography machine technology.

The objective lens system is the difficulty of domestic immersion lithography machines.

Fortunately, Li Yunhai had made preparations in advance.

Before ASML started the research, Li Yunhai had already reached a cooperation with Carl Zeiss, and it was an exclusive cooperation!
In other words, Carl Zeiss can only develop relevant objective systems together with Sihai Group.

Currently, the most advanced objective lens system in the world can only reach 90nm.

Li Yunhai has a longer-term vision. He requires the Sanjiang Research Institute to make greater breakthroughs as soon as possible.

However, at present, 90nm is enough for a long time.

The development of science and technology is like squeezing toothpaste, growing slowly rather than happening all at once.

The workbench is the less difficult part of an immersion lithography machine.

The original Sihai Research Institute has already developed a workbench, and after being improved by Ji Wenshu's team, it has now achieved 134nm precision control.

Therefore, for immersion lithography machines, the problem of the workbench is basically solved.

The immersion system consists of control software, liquid sensors and controllers.

Sanjiang Research Institute has made a major breakthrough in immersion control systems, laying the foundation for the realization of immersion lithography machines.

With the realization of domestic immersion lithography machines, my country will be able to manufacture higher-level chips!

Including future 14nm and 7nm chips!

In this way, we can greatly reduce our dependence on imported equipment.

The breakthrough of immersion lithography provides great hope for my country's chip manufacturing industry. As long as the objective lens system can achieve a breakthrough, a fully domestically produced immersion lithography machine can be realized, making it less difficult to domestically produce 7nm chips in the future.

Li Yunhai is laying out a big plan and playing a big game of chess.

However, he still had to rely on Carl Zeiss to provide the objective system.

The thing Li Yunhai hates most is to let others strangle him!
The reason why he agreed to sell Sihai Group was also due to these considerations.

Because Sihai Group attracts attention because of its size!

Moreover, Sihai Group has some shares from the military side.

In the eyes of foreigners, the red color of Sihai Group is very obvious!
If they knew that Sihai Group is a world leader in developing the immersion lithography machine, they might become jealous and impose restrictions on Sihai Group's exports.

Li Yunhai simply went all out and sold the Sihai Group outright!

He controlled the business and scientific research through Sanjiang Company, and then produced immersion lithography machines.

Just after he completed the layout, Ji Wenshu lived up to expectations and successfully developed a new generation of lithography machines!
There has never been a commercial war or any production conflict between Sanjiang Company and foreign companies.

Therefore, the cooperation between Sanjiang Company and Carl Zeiss can definitely be maintained.

Li Yunhai couldn't say how long it could last.

He can only try his best to speed up the pace of independent research and development on the premise of cooperation.

Li Yunhai’s motto is to believe in yourself and not let others control your destiny!

At this moment, Ji Wenshu started the test machine and explained it to Li Yunhai while operating it.

When the first domestically produced 134nm chip was produced, excitement flashed across Li Yunhai's calm face!

In fact, he didn't expect that he could actually succeed!

Li Yunhai only knew the general principle of immersion lithography, but he had no confidence that it could be successfully developed in China.

All the credit for this really belongs to Ji Wenshu’s team!
Li Yunhai rewarded them with 10 million, which is not too much!
At this moment, looking at this great invention that was actually successfully developed by the company he controlled, Li Yunhai was so excited that he couldn't express it in words!
He understood the significance of this invention better than anyone else present!

Because he is from the future.

He has experienced those days when he was strangled by others!

Although Professor Ni and others are stronger than Li Yunhai in the field of science and technology, they do not know what this technology means to us.

At this moment, Li Yunhai really felt a sense of relief that his long-cherished wish had come true!

The greatest sense of accomplishment he had felt since his rebirth came at this moment.

Even when Sihai Group went public and its total market value exceeded 100 billion, he had never been so excited.

Li Yunhai felt that the meaning of his rebirth lies in this!

He lived his life again and accomplished something great!

Seeing Li Yunhai so excited, Ji Wenshu thought it was a product she developed, which was not to Li Yunhai's liking, so she asked nervously: "Mr. Li, do you think it's okay?"

Li Yunhai laughed and said, "Not bad! Not bad! President Ji, you guys are really great! You have done a great job!"

Professor Ni said: "Mr. Li, this new generation of lithography machines should be able to be used for more than ten years, right?"

Li Yunhai said: "More than that, 30 years is no problem! The chip industry is a toothpaste squeezing industry. The latest lithography machine is in our hands. We can control the development direction of the entire industry!"

Professor Ni asked: "Mr. Li, what you mean is that we want to strangle the foreign chip industry? To prevent them from producing the latest chips?" (End of this chapter)
