China began to study lithography machines in the 1970s, and initially asked the Institute of 1445 of Nanjin University to conduct research.

In the 1970s, China had already realized the importance of lithography machines and quickly began to study lithography machines. In 1982, the KHA-75-1 lithography machine from the 109th Academy of Sciences. The level of these lithography machines was not low at that time. The most conservative estimate was less than 4 years compared with the most advanced canons at that time.

In 1985, the Institute of Mechanical and Electrical Engineering and Electrical Engineering developed a step-by-step lithography machine prototype. Through the technical appraisal of the Ministry of Electronics, it was believed that it reached the level of 4800DSW in the United States. This should be the first step-by-step projection lithography machine in China, using a 436-nanometer G-line light source. According to this time node, the gap between China and foreign countries in step-by-step lithography machine is no more than 7 years.

Looking back from history, China's semiconductor industry has actually developed very well. It has already started in the 1950s. Next, we just need to follow the steps and develop slowly. China will definitely be one of the leaders in the future semiconductor and electronics industries.

At that time, China's semiconductor industry was second only to the United States.

The older generation of scientific researchers dedicated their youth and created the semiconductor industry in China. At that time, although the semiconductor industry in China did not surpass the world's first level at that time, the gap was not big. More importantly, it built a full industrial chain from single crystal preparation, equipment manufacturing, and integrated circuit manufacturing, which basically did not rely on foreign imports. In other words, China used the supply chain of one country to catch up with the entire supply chain of the alliance of developed Western countries. You must know that Intel also used neon lithography machines at that time.

However, why hasn’t China’s lithography machine technology developed?

Now, the lithography machine used in China is 193nm argon fluoride laser lithography technology. At this time, the Netherlands, far away from the ocean, had developed euv lithography technology, using 13nm extreme ultraviolet light technology.

This technology is at least twenty years behind the other party.

What are we doing in the past twenty years?

It’s not that the country does not develop, but that there is no way.

If you look at the development of China carefully, from the beginning to the point where everything is in trouble, to now, almost 90% of people have enough food and clothing, which is due to the country's vigorous economic development.

At that time, our country was so weak that no one dared to bully it. Good steel was used on the blade. China had no choice but to use all its economy to develop weapons. Because two bombs and one satellite made our country no longer dared to be ridden on the head at will.

But at a glance, the people of the whole country are all poor.

This is a very realistic question. When most people can’t have food, how can they talk about developing lithography machines? What’s the use of developing them?

At that time, China faced two choices: either sacrifice the national level and invest money in basic scientific research. Or sacrifice this industry and focus on improving the quality of life of the people.

Until now, behind the common food, clothing, housing and transportation we have become accustomed to is the efforts of several generations of scientific researchers.

We have successfully made the people of our country start to have a meal and become rich. With the current situation of improving people's cultural level, we finally turned our attention to the so-called lithography machine again.

A lithography machine, in layman's terms, is the most important instrument for producing chips.

There is no need to say how important the chip is.

A small chip has reduced the large area of ​​computers that occupied the entire room in the 1970s to the host that can be picked up with one hand now. The most important part of the future smartphone is also the chip.

However, even in 2020, China could not make chips by itself at that time, because our lithography machine technology could not be achieved.

Although our country's scientific researchers have created two bombs and one satellite, made aircraft carriers, and made the most advanced weapons, the only lithography machine is really not able to be made.

Because the difficulty of making this thing is the world's most difficult.

The lithography machine contains the essence of many disciplines such as mathematics, optics, fluid mechanics, precision instruments in polymer physics and chemistry, as well as the most animated image recognition.

The euv lithography machine is the world's top engineering technology, material technology and design level. The engineers who made this instrument can adjust the position of a part for decades and polish it millions of times. With the current technical level of China, it is very realistic to say that it cannot be made.

In the future, only the Netherlands and Neon can produce lithography machines. Only Intel in the United States, Samsung in the Kimchi country, and TSMC in Wanwan can produce chips.

It is not that these places have the ability to make lithography machines. The company that made lithography machines in the Netherlands is Asmr, but the parts of the SUV lithography machines they made are 90% from other companies.

Deguo provides world-class Zeiss lenses, optical technology comes from Neon, process distribution technology comes from Intel TSMC and Samsung. There are even Swedish bearings and French valve parts.

The companies that provide these technical support are all shareholders of Dutch Asmr.

Whenever new lithography machines are released, these companies will be given priority, so the United States never worrys about not having chip production.

With the United States as the leader, they can actually control Asmr and TSMC. In this way, the transformation of later generations was blocked by the United States.

When they are gone, they fall into the worst situation. The United States does not want China to be exposed to the latest lithography machine technology. If the lithography machine technology cannot be improved, it proves that neither the Internet of Things artificial intelligence nor technology can develop.

Although the lithography machine technology in China in later generations has reached 90nm, it is still 15 years away from top countries.

Because of the small chip, China is clamped everywhere.

Even now in 1999, the official already had a premonition in this regard, so when Deng Zhonghan brought foreign technology back to the creation of Zhongxingwei, the official would let him pass the review quickly through the green channel.

However, due to the official support, they can only provide support without any convenience. As for other aspects, they will eventually need Deng Zhonghan to do it himself.

So what is Deng Zhonghan’s most lacking now? This is the most fundamental reason why he found Chu Han.

When Deng Zhonghan revealed his name, Chu Han already knew what the other party wanted, but he still sat calmly in his position, silently waiting for Deng Zhonghan's narration.

This future academician of the Academy of Engineering, founder of Zhongxing Micro Group and chief scientist, said carefully: "Boss Chu, in fact, I'm looking for you this time, there's nothing else. I'm...just..."
