When Chen Jie heard him say this, he immediately opened his mouth to explain.

However, Professor Krueger said slowly: "Mr. Ni, the original accuracy of this lithography machine was 190 nanometers, but we have used a special method to increase its accuracy by about double. ”

"How is this possible? How could there be such a technique! ”

Ni Guangnan was dumbfounded, still in disbelief.

Even Director Zhang, who was standing behind and had not spoken, looked like he had seen a ghost.

How can such a big technological leap be made? Or in chip manufacturing, a cutting-edge field that the world has been working.

This can no longer be described as overtaking in corners.

It's basically opening up a new track!

Seeing that they didn't believe it, Chen Jie had no choice but to let Professor Kruger explain it roughly.

Infinity, Inc., the "first" immersion lithography technique, uses a variety of liquids with different refractive indices, such as 1.55 to 2.0 liquid materials.

After many trials and technical improvements, a special liquid was finally selected as the main material for immersion lithography.

The refractive index of this liquid is as high as 1.7, and its light transmittance is also fully suitable for large-scale production.

As long as Professor Kruger successfully transforms this lithography machine, Infinity can be far ahead of the world!

Even if a more advanced lithography machine is launched abroad, they can immediately use immersion technology to surpass their opponents!

Moreover, the biggest advantage of this technology is the manufacturing cost.

Generally speaking, the newly developed lithography technology in the world will have immature technology and low yield.

As a result, mass production was not possible for a long time.

The immersion technology adopted by Infinity relies on a mature and stable lithography machine, and after solving the core liquid material problem, its yield rate is several times higher than that of new technology!

To put it simply, they only need to use a variety of liquids with different refractive indices, and they can freely adjust them to get lithography machines with different precisions!

What Professor Kruger said was in a good way, and it didn't seem to be a fake at all, while Ni Guangnan and Director Zhang just froze in place, their mouths wide open, and their brains went blank.

They didn't expect that this seemingly simple method would have such a big impact on the chip manufacturing process.

Several disciplines are really complementary to each other.

Science has always had shortcuts, but you just didn't find it.

After a long time, Director Zhang changed his usual calm attitude and said in an extremely serious tone: "This technology must be kept strictly confidential and must not be spread!" ”

"In addition, if you need any support, you can also ask for it, and I will apply to the above!"

He added.

Chen Jie nodded and grinned: "Director Zhang, we are short of professional researchers now, I hope you can think of a way." ”

After he finished speaking, everyone looked at Ni Guangnan in unison.

At this time, Ni Guangnan has not come back to his senses, and when he came to Infinity Company today, what he saw and heard in the laboratory shocked him too much.

But when he thought that he could participate in designing a real domestic chip, or a chip that is leading the world level, he couldn't help but be excited.

He raised his head and saw that everyone was looking at him, and he couldn't help but sigh with emotion, although the senior management of such a private enterprise has a low level of education, but there is no doubt about patriotism.

He had also heard a little about the fact that they did not hesitate to go bankrupt and did their best to protect the Xiangjiang stock market.

Perhaps it is precisely because of this feeling that they are willing to spend a huge amount of money to devote themselves to the research of chips.

After thinking about this, he immediately expressed his willingness to join Infinity and participate in the research and design of chips!

After receiving his personal promise, Chen Jie and Lin Zeju were also very happy.

They appointed Ni Guangnan as the chief designer of the chip on the spot, with a monthly salary of 700,000 RMB.

This salary scale is not arbitrary.

Ni Guangnan once studied in Canada, and because of his research on pattern recognition and graphics, he got the opportunity to work in a Canadian research institute.

The monthly salary given by Canadians is about 7,000 Canadian dollars. (equivalent to about 38,000 RMB)

This was in 1981.

But Ni Guangnan still gave up, he resolutely returned to China, took a salary of 70 yuan a month, and engaged in computer research.

At that time, when he returned to China, he could have worked on the world's cutting-edge pattern recognition project in the computer institute, and "reached or approached the world's advanced level" to win respect.

But Ni Guangnan didn't, he chose to study the most valuable application and the most urgently needed Chinese character processing technology in the market.

It has to be admirable.

With the addition of Ni Guangnan, Professor Kruger did not make any reservations, and directly told him about the immersion lithography technology.

Including his own ideas during this time, he said it in one go.

The two sat together and had an in-depth discussion.

What Director Zhang is most concerned about at this time is the source of this technology, who invented it?

If it is researched by this foreigner, then the ownership of this technology is somewhat controversial.

He quietly walked up to Chen Jie's side and asked about it.

However, Chen Jie deliberately made a sloppy eye, saying that he would wait for the new batch of researchers to arrive, which made Director Zhang blow his beard angrily and stare at him.

Unexpectedly, Chen Jie still had scheming and wanted to negotiate conditions with him.

At the critical moment, Lin Zeju stood up and told him that it was Chen Weidong who called Professor Crook and then improved it through many experiments.

This answer made Director Zhang gasp.

He shook his head again and again, not believing it.

Chen Weidong is a high school dropout, and he is very good at finance, and everyone can barely accept it, because finance does not involve hard technical aspects.

It's not impossible to get started and become proficient.

But now you tell him that he even understands semiconductor chip research, isn't this nonsense!

They have already made it clear that Chen Weidong and Chen Jie, all the backgrounds of the two of them, as far as their poor countryside and the physics teacher in the school are still only college diplomas.

Don't talk about any chips, even if it's the most basic home circuit diagram, if they can read it, they won't be messing around in high school.

"Believe it or not, don't run over to us if you want to use it when the time comes."

Chen Jie turned around angrily, a little unhappy, he looked down on them so much.

Although Director Zhang still couldn't believe it, when he heard Chen Jie say that this technology belonged to Infinity Company, a hanging heart gradually fell.

This visit to Infinity Company was very rewarding.

The only thing that worried him was this foreigner named Kruger.

Regarding his identity information, all the resources used on it have not been found, and there is not even a clue at all.

I only know that he was personally found by Chen Weidong.

Now Infinity has the initial conditions for the development of high-precision technology, and in time, he has no doubt that it will produce some scientific research results.

But these technologies must be in the hands of their "own people".

He really wanted to talk to Chen Weidong about this topic, but when he thought that he was still in the island country, he delayed returning.

I couldn't help but sigh deeply.
