From university academician to chief academician

Xia Xin International, Lithography Machine Research Institute!

When studying carbon-based chips, Ye Fei’s idea is to first study photolithography machines, which are the top priority for manufacturing chips.

Without a photolithography machine, it is certainly impossible to manufacture chips.

There are more than 3,000 researchers in the Lithography Research Institute. After learning that Ye Fei was leading their research, they were very excited and very motivated.

It is as if a photolithography machine capable of producing high-quality chips will be developed tomorrow.

Who doesn't know what Ye Fei wants to study, and he has never failed so far.

Therefore, they also have full confidence in Ye Fei when it comes to lithography machine research.

In the research of lithography machines, we must first figure out the theory, and then carry out applied research.

Of course, Xia Guo has made great progress since he has been studying lithography machines for many years.

Therefore, Ye Fei’s team collected existing technologies and conducted research on them.

The study of lithography machines is called lithography technology.

Its core technologies are photoresist, contact and non-contact lithography technology, exposure system, photolithography machine adjustment system and random error control.

meeting room!

Ye Fei sat at the head of the table, and below him sat ten researchers, all of whom were the team leaders and deputy team leaders of each group.

Ye Feidao: "Now foreign countries will not sell photoresist to us, so we have to make our own photoresist."

Photoresist, also known as photoresist, is the most important material in photolithography technology.

It is a light-sensitive mixed liquid composed of three main components: photosensitive resin, sensitizer and solvent.

The characteristics of photoresist have a great influence on the performance of photolithography machines, so it is very important to choose the appropriate photoresist.

Ye Feidao: "Moreover, we are studying carbon-based chips, so we need to create a photolithography machine suitable for carbon-based chips."

"So, we also need to develop photoresists suitable for carbon-based chips."

"Photoresist research team, I want you to travel all over the world and develop a photoresist suitable for carbon-based chips. Are you confident?"

The two researchers stood up and shouted: "Yes!"

The research on photoresist seems to be just a kind of glue, but the principles used in it are very complicated.

It requires knowledge of physics, chemistry, materials science, mechanical engineering, and electronic engineering to develop photoresist.

Researching chips is a very large project. It is more difficult than an atomic bomb. It requires the efforts of many people to develop it.

The research on photoresist alone consumes a lot of manpower, material resources, and financial resources.

You have to travel all over the world to find a lot of materials, theories and techniques.

Only by poaching talents from all over the world can we develop photoresist.

Ye Fei nodded and said, "Sit down!"

"Contact and non-contact photolithography technology requires the use of photoresist."

"So, contact team, you have to work together with the photoresist team."

Contact lithography technology refers to a technology in which the photoresist is in contact with the mask and is irradiated by photolithography light.

Non-contact photolithography technology is to perform photolithography after air or vacuum is separated between the photoresist and the mask.

"Yes, Dean!" Two researchers from the contact group stood up and said.

Ye Fei nodded and said, "Sit down!"

Ye Feidao: "I learned that Juguang Technology developed a technology some time ago that is very suitable for exposure systems."

"Light field homogenizer, light explosion system team, you can contact the people from Juguang Technology to see if you can cooperate in research."

"Yes, Dean!" said the two leaders of the exposure team.

"Photoresist, contact and non-contact lithography technology, and exposure systems, these three studies are all centered around photoresist research."

"The most difficult thing about lithography machines is the error. Our country has been studying lithography machines for so many years, and it is no longer a difficulty in theory and technology."

"I heard that there was once a college student in China who built a photolithography machine in his dormitory."

"Although the manufacturing accuracy of this photolithography machine has not reached the level of high-end process technology."

"However, it can be seen from this that manufacturing lithography machines in our country is not a fantasy."

"But the reason why our country cannot build a photolithography machine is because of the error."

When everyone heard this, they nodded in their hearts.

Indeed, the improvement of equipment and technology in the entire semiconductor industry chain is actually continuously reducing manufacturing errors.

Chips produced by good photolithography machines and chips produced by poor photolithography machines.

In appearance, the difference is not big.

But upon careful observation, there are still some differences in their transistor arrangements.

It is these differences that make the quality of chips vary greatly.

After all, a nanoscale chip, a chip the size of a fingernail, has tens of billions of transistors.

How to make these transistors appear completely according to the design on the chip design drawings.

This requires high-precision control during the manufacturing process.

Ye Feidao: "Therefore, the adjustment system and random error control of the lithography machine are the most difficult and core parts of the lithography machine."

"I will join in these two studies and study them together."

The two group leaders, the regulating system group and the random error control group, felt somewhat relieved after hearing this.

With Ye Fei joining in, I believe their research will be much easier.

"Let's adjourn the meeting and go back to prepare and start research."

After saying that, Ye Fei walked out of the conference room.

"Dean Ye!" Ye Fei was about to walk into his office when Qu Guangfu came up from behind him.

Ye Fei turned to look at Qu Guangfu and asked, "Director Qu, is there something wrong?"

With that said, Ye Fei pushed open the office door and said, "Let's go in and talk if we have anything to do!"

"Okay!" Qu Guangfu said.

After saying that, the two walked into the office.

After Qu Guangfu entered, he glanced at the office and said, "Dean Ye, are you satisfied with the office?"

The office area is relatively large, more than fifty square meters, and the decoration is simple.

There are desks, bookshelves, a set of sofas, and coffee tables, with a small tree placed in each corner.

Sunlight shines in through the floor-to-ceiling windows, making the office bright and clean.

This office had been renovated before Ye Fei came, and all the decorations were new.

The decoration style was also designed by Qu Guangfu after consulting some designers.

Qu Guangfu said: "If you feel dissatisfied, I will ask someone to change it immediately."

"No need!" Ye Fei quickly shook his head and said, "I'm very satisfied."

Ye Fei's requirements for food and accommodation are not very high, as long as he can have food and accommodation, and the office can be used.

With that said, the two sat on the sofa, and Ye Fei asked his assistant to bring them tea.

Ye Fei asked: "Dong Qu, what's the matter?"

Qu Guangfu said: "Because you joined our company to research chips."

"The higher-ups talked to me. At that time, I also talked with research units such as the Academy of Sciences and Shuimu University, and lithography equipment manufacturers such as Modu Microelectronics and Kyoto Kokubo Lithography."

"We hope they will assist us from above. If we have any difficulties, we can raise them to them."

Xiaxin International may not be considered a private company, but it is a private company controlled by a state-owned enterprise.

Therefore, strictly speaking, it is considered half a state-owned enterprise.

"This time, the higher authorities are very determined to develop chips."

"They hope to develop the chip as soon as possible."

"After all, as the world's largest consumer of chips, we cannot remain chipless!"

Ye Fei nodded and said, "That's true. I will definitely develop the chip as soon as possible."

Qu Guangfu said: "Yesterday, ASML suddenly submitted a large number of lithography machine technologies to Xia Guo with more than 3,000 lithography technology patents."

Ye Fei frowned slightly and said, "What are they doing?"

Ye Fei certainly doesn't think ASML is a well-intentioned act.

ASML is a Dutch lithography company and one of the world's largest semiconductor equipment manufacturers.

The world's best photolithography machine technology is in the hands of ASML.

Qu Guangfu said with a smile: "Of course we want to use their technology when we develop lithography machines, so that they can also participate in our research."

"After all, lithography machine is a very complex and very difficult research."

"It's impossible to completely localize it. Some foreign photolithography technologies will definitely be used."

Ye Fei sneered: "They are talking nonsense."

"I just want to make it completely localized."

When Ye Fei started researching lithography machines, he wanted to fully localize them.

If the things he researches have foreign technology, then foreign countries can also enjoy the benefits.

This is equivalent to giving benefits to foreign countries in vain.

Qu Guangfu said: "Not only that, they are also preparing to invest in some of my country's top chip manufacturing companies to help them develop lithography machines."

"This can significantly slow down your research."

"After all, if you think about it, everyone wants to develop a high-end lithography machine."

"Then they will focus more on themselves and not on helping other companies."

"In this way, when we look for help from other companies when researching lithography machines, they will also push us away."

Qu Guangfu shook his head and sighed: "These Westerners also learn the tricks of our ancestors."

"Build the plank road openly and cross Chencang secretly!"

"But they are a conspiracy and we can't stop it."

Ye Fei sighed in his heart, feeling helpless.

But Ye Fei can also understand if Xia Guo really develops a high-end photolithography machine.

Then ASML's high-end lithography machines will no longer be sold to Xia Guo, and it will be very difficult to do business with Xia Guo in the future.

Therefore, if Ye Fei can be prevented from developing a photolithography machine at this time, he must stop it.

Qu Guangfu said: "But please don't worry. Faced with this situation, the higher-ups have already contacted many companies and asked them to help us."

Ye Fei nodded and smiled: "Even if ASML blocks it, it may cause some difficulties for us, but we still have to develop our own lithography machine."

Qu Guangfu nodded and said: "That's right. No matter how many obstacles there are, we can't stop us from owning the photolithography machine that belongs to Xia Kingdom."

Netherlands, ASML headquarters, chairman's office!

The ASML director said: "Sean, do you think what we are doing is useful? Can it really stop Ye Fei from developing a photolithography machine?"

Sean is chairman of ASML.

Sean said: "I don't know if it will be useful, but there must be some obstacles."

"Don't forget, we submitted more than 3,000 lithography machine patents to Xia Guo."

"Even if we can't stop Ye Fei from developing a photolithography machine."

“But Ye Fei’s development of photolithography machines will definitely use our technology.”

"As long as our technology is used, we can profit from its lithography machine research."

Sean shook his head and smiled: "Whether Ye Fei develops a photolithography machine or not, we can all benefit from it."

"The inability to develop a photolithography machine is the biggest benefit to ASML."

"The development of a photolithography machine will also have certain benefits for ASML."

The director worriedly said: "What if Ye Fei goes completely local?"

Sean was stunned for a moment, then shook his head and said with a smile: "Do you think the photolithography machine is as simple as making a jack-o'-lantern?"

"It is more difficult to manufacture than an atomic bomb. How can it be completely domestically produced?"

"Even ASML cannot achieve complete localization."

"No country in the world can achieve complete localization of photolithography machines."

The director thought for a moment and realized that indeed, the photolithography machine was not a jack-o'-lantern and could not be developed so easily.

No lithography machine developed by any country in the world is completely domestically produced.

Thinking of this, the director felt relieved.

The director nodded and smiled: "That's true!"

Sean said: "But we can't let down our guard. If Ye Fei develops quantum chips, then we will develop photonic chips."

Carbon-based chips are one of the core technologies for the next generation of supercomputers.

A supercomputer is a quantum computer.

Therefore, carbon-based chips are also called quantum chips.

Photonic chips are generally used in mobile phones, and their performance is much better than 5nm silicon-based chips.

Carbon-based chips are generally used in computers and can also be used in mobile phones.

However, it is mainly used on computers, and its performance on mobile phones is far inferior to that on computers, and is similar to the performance of photonic chips.

However, carbon-based chips are much more difficult than photonic chips.

Sean said: "Photonic chips have always been our main research area."

"If we can develop a photonic chip, then even Ye Fei can develop a quantum chip."

"We can also compete with him in the mobile phone market."

"Maybe the quantum chip he developed is not as good as our photon chip!"

The director's eyes lit up and he said: "That's right!"

The director asked: "What progress is our photonic chip research at?"

Sean said: "It will take more than half a year to develop it. I think our photon chip has been developed, but Ye Fei's quantum chip has not been developed yet!"

Sean smiled: "Speaking of which, we may still have the upper hand."

"After all, quantum chips are not easy to develop."

"By the time Ye Fei develops a quantum chip, our photonic chip will already have a head start in the mobile phone market."

"Ye Fei's quantum chip wants to compete with us, but it is already at a disadvantage."

The director smiled and said: "That's right!"

Sean shook his head and said regretfully: "It's a pity that we can't mass-produce carbon nanotubes, otherwise we can also develop quantum chips."

"This is the core technology of quantum computers!"

"The future world must be the era of quantum computers."

"If Ye Fei develops a quantum chip, he will definitely be able to kill everyone in the future."

The director frowned and asked: "Beiliguo hasn't developed a mass production method for carbon nanotubes yet?"

"No!" Sean shook his head and said: "The batch manufacturing method of carbon nanotubes is a global problem. Only Ye Fei has developed it so far. I don't know when Beili will be able to develop a batch manufacturing method of carbon nanotubes! "

Beiliguo, MIT, Nanomaterials Research Institute!

Boy said anxiously: "Lucas, when will you develop a method for batch manufacturing of carbon nanotubes?"

"The superiors are very anxious about this matter, and Ye Fei has begun to develop carbon-based chips."

"If we don't have a mass production method for carbon nanotubes, we don't have carbon-based chips, and we can't develop carbon-based chips."

Lucas said helplessly: "What's the use of urging me? Can research be used to induce it?"

Boyi was anxious and helpless. He found that since meeting Ye Fei, everything went wrong for him.

Ye Fei developed Web3.0. He dug V God to Beili Country, but has not yet developed Web3.0.

Later, Ye Fei went to research and develop fullerenes, but discovered C72 fullerenes.

Then Ye Fei discovered high-purity graphene, allowing Xia Guo to produce the highest-purity graphene in the world.

You know, in the past, the highest purity graphene in the world was produced in Beili.

Next, Ye Fei developed a method for batch manufacturing of carbon nanotubes. Unexpectedly, it only took more than half a year for Ye Fei to successfully develop it.

After having high-purity graphene and carbon nanotube batch manufacturing methods.

Ye Fei finally took action on the chip.

Moreover, what is being developed is carbon-based chips.

No country in the world, except for Xia, is qualified to develop carbon-based chips.

Boyi felt desperate: "If Ye Fei is allowed to develop a carbon-based chip, the higher-ups will be furious, and I won't be able to sit in this position."

"Why would someone like Ye Fei appear in Xia?"

"And our country, Beili, is the world's strongest technological country and the strongest educational country."

"But it failed to cultivate talents like Ye Fei."

"Boss!" At this time, a young man walked up to Boyi and said excitedly: "The Kangxing Blockchain Research Institute just sent news that their Web3.0 development was successful."
