Using 248 nanometer technology to produce 193 nanometer chips, the contractor of the American Land Warriors Project would definitely make fun of him if he knew about it.

This is not a question of how difficult it is. It is an impossible question.

Just as a brush cannot write a font as thin as a pen, the 248-nanometer lithography technology cannot produce a 193-nanometer chip.

But scientists in the world are using a new technology that has passed the test to make this impossible possible!

This technology is worthless. But in 1996, no company had a sudden improvement in existing manufacturing technology using this method.

Therefore, in order to protect this exclusive secret, German and French engineers only helped the world's technicians install production lines in the clean factory of the experimental factory, and were unable to enter the world's laboratories.

Although everyone is curious about how the Universal uses rough processing technology to produce 193 nanometer chips, it is obvious that Universal will continue to keep their mysterious ground veils and do not intend to share them with the world.

There are joint security personnel on duty around the laboratory responsible for transforming the lithography machine 24 hours a day.

This security team is composed of the security team members of the Universal Corporation, military commandos, and plainclothes agents from Guoan. The strictness of its guard is probably not as strict as Zhongnanhai.

As soon as Xiao Qiang signed the letter, he drank a glass of champagne with the German and French military officers stationed in China. He accused them of guilt and left.

For specific reception work, other people are responsible for it.

He walked to the laboratory, and the security team on duty at the door saluted him. The military commando also stood attentive with guns.

In the past, Dihuanyu Company only achieved the dominant position of global personal computer operating systems in software. On the other hand, it is a catalyst for domestic technology improvement. From the role of scientific instruments and technological pioneers, domestic units provide technical support.

But both aspects have very limited actual effects.

The achievements in software are more of an influence that makes the whole world understand that China is already a modern country with developed technology. Under the influence of comprehensive means such as the Internet and movies, it has changed the West's understanding of China.

Its function is only here.

Progress in software cannot naturally make the same progress in hardware.

In comparison, for the domestic science and technology community, this achievement instruction is spiritually encouraging. What they value more is the support of Universal Corporation for domestic scientific research.

Scientific instruments have shortened the gap between us and foreign research institutes in equipment.

The benefits it gives to domestic research departments are far greater than the invisible technological influence of software and other software. Of course, due to the Chinese environment of the software and the huge software compilation group formed after being promoted in China, it is still very helpful for us to develop our own special software, but it is not as helpful as high-precision scientific instruments.

However, since our - Piao Astronomy - is too low after all. We are developing and we are not resting abroad.

Therefore, although the country has become more and more fully aware of technology as the primary productive force, and has been continuously increasing its investment.

However, even if the domestic top-down, they attach great importance to high-tech research and development. Due to the technology blockade in foreign countries, we still have no shortcuts to take. We cannot directly cross the research path that foreign countries have taken. We still have to start research. Therefore, the domestic efforts to catch up only make this gap no longer expand. The gap between the highest technical level in China and abroad has not narrowed.

We have Fc-1, but the US F22 is about to be developed successfully; we have the Type 90 tank, and the West has evaluated the future combat system (FCs) and MIA3; we have just started to develop array radar. The Western active array radar has begun to test aircraft; we are starting to build a new frigate. The US Aegis has been included in the equipment and started mass production; we have finally broken through the micron technology mark. The West has popularized 360 nanometers and 248 nanometers. It has also been used on a large scale by many high-tech electronic companies and has begun to launch an impact on 193 nanometers...

Therefore, although the domestic scientific research environment is at its best in history, state-owned and private research units have been established like mushrooms after a rain with the support of scientific instruments supplied by Universal Company at low prices.

But in terms of practical research progress, there is still a huge gap between us and the West.

Just when the domestic technology industry felt that time was tight and surrounded by a heavy sense of oppression, Universal Company launched digital individual equipment in a shocking way!

This is a piece of equipment that can change the future war mode. More importantly, it was first proposed by China and made it practical!

Even the United States, which first proposed this concept and invested huge amounts of money to verify it, did not have the digital equipment that reached scale and leaped onto the international stage and showed strong combat effectiveness in actual combat.

The Chinese military has been constantly experiencing this equipment from the original "Oh? Is the Universal World doing it?" to surprises after the confrontation exercises, and then to satisfaction with the improvements. Its desire for digital equipment has been progressing again and again.

By the time Saudi Arabia used a digital soldier in the land to resist and severely damage a battalion of the Iraqi Republic Guard, the military's expectations for Universal Company had reached a peak.

Not only was the military ecstatic, but the government was also surprised to discover the benefits of "equipment diplomacy".

By using exclusive supply of digital equipment, we have successfully broken the blockade line that the United States has taken the lead through a series of public relations operations. There is no need to say about the achievements of the Middle East, and Europe, Germany and France, which had wanted to break away from the United States, and began to secretly relate to China.

After that, the "secret crossing Chen Cang" plan for this cooperation between the three countries was formed. Use equipment to exchange for advanced chip production lines.

Originally, what Xiao Qiang hoped most was to secretly import a set of large high-precision processing machine tools from abroad, but Germany and France decisively rejected it. Although the 248-nanometer production line is advanced, it has been popular in the West. Even if it is given to China, it has nothing. Besides, it has obtained the production line. China cannot domestically produce it without ultra-high precision mechanical production capacity and optical support.

But large ultra-high precision machine tools are another matter.

With this set of equipment, China can use it as a parent machine to produce a large number of high-precision machine tools, which directly threatens the military security of the West.

If they agree to the global demands, not to mention that the United States will definitely impose sanctions like crazy, they may even dispatch military machines to stop them. Even in their country, they will never be allowed.

Therefore, the military attaches great importance to the two sets of eight-inch production lines that are smuggled back this time. We hope that Universal will continue to create miracles.

Universal said it would transform this equipment. Suddenly, both the military and the government provided the highest support.

Huanyu Company said it would keep it confidential, and the military local commando and the national security department immediately sent the strongest lineup to assist Huanyu Company to provide the most stringent protection of the laboratory.

Paying tribute to Xiao Qiang, the security team members are also equipped with the most advanced equipment: digital individual equipment!

All of them have heard of the legend, including military alert personnel and Guoan Di plainclothes. It is said that the development of digital individual equipment by Universal Corporation is only derived from Xiao Jianjun's statement that he wanted to test digital soldiers. In order to please his father, the boss of Universal Corporation made this set of equipment and made a big splash.

It's that simple.

This is just like what the Bible says: There must be light, and so there will be light.

This young man named Xiao Qiang is like a mysterious immortal. As long as he wants, he will not be able to get it. So, what kind of surprise will the transformation he has done this time bring to them?

Xiao Qiang entered the laboratory. He took off his clothes and took off the dust from his body. He illuminated the ultraviolet irradiation room for several minutes before he changed into a one-piece sterile suit, opened the door, and entered the interior of the laboratory.

There are two lithography machines in the laboratory in nearly a thousand square meters. The engineers from the world are not in a hurry to start immediately. They are surrounding the lithography machines and are discussing according to the technical manual.

Next to the laboratory, there are various high-precision measuring instruments and automated robotic arms. Half a room is filled with it.

Only these high-precision measuring instruments can ensure that the lithography machine can be successfully restored after disassembly.

Xiao Qiang found Wang Gong from Huanyu Precision Instrument Company and asked: "How is it? Is it difficult to transform the technology?"

"Very big!" Wang Gong bluntly admitted, "This equipment is very quiet and we dare not take action before we figure out all the technical details. If we mess it up, this equipment worth hundreds of millions of dollars will be finished!"

"When can the transformation be completed?" Xiao Qiang was a little nervous. He had signed a formal contract with Germany and France. If it could not be completed, he would have the only way to go bankrupt except to default on the debt.

Wang Gong saw his nervousness and comforted him: "Boss, don't worry. We have conducted verifications many times before, and there will be no problem. Now we mainly need to figure out the internal structure details of the lithography machine. As long as we understand this thoroughly, the transformation itself is very simple. Restoration will not bring difficulties. Sharpening the knife will not delay the chopping of wood. This is necessary."

These scientific researchers are used to the slightest scientific research process. If Xiao Qiang had not been the company's boss, they would have known that Xiao Qiang was under tremendous pressure. They might have contradicted him long ago.

After hearing his explanation, Xiao Qiang was still worried, but he still forced himself to calm down.

He knew that Mr. Wang was right.

The transformation of equipment is not under the guidance of original technicians. No matter how cautious it is, it is not an exaggeration.

As for the transformation of new technology, Xiao Qiang was a little funny when he remembered the first time he heard this technology.

The reason why he was shocked at that time was not because the technology was so difficult, but because it was too simple, so simple that he thought he had heard it wrong. Using such a simple method, he could greatly improve the processing accuracy of the lithography machine?

This new technology was named "Immersive Lithography" by Precision Instrument Company.

It sounds like a great invention.

But when Xiao Qiang understood the principle, he was stunned on the spot.

Immersive lithography technology is to fill the liquid between the lithography lens and the silicon wafer to be etched!

It was so simple that Xiao Qiang thought that Wang Gong and others were forced to make him anxious. So he came up with this ridiculous statement to fool him. It was not until he heard Wang Gong explain the principles and saw a small modified 800-nanometer lithography machine on site in the laboratory that successfully carved intensive graphics of 550-nanometer ground. He was immediately moved.

In normal lithography machines, there is no occlusion between the lithography lens and the silicon crystal element.

Of course, from another perspective, the air is filled among them.

The immersion method is to replace the air in the middle with liquid. Since the liquid has a refractive index, when ultraviolet light passes through the liquid medium, the wavelength of the light source will be shortened, thus playing a role in fine engraving.

Using the mainstream 360-nanometer technology, using a liquid with a refractive index of 1.5, its light waves can become 240 nanometers!

The 248-nanometer lithography machine that Universal Company has worked hard to get back, adopting the 15-yuan immersion technology, and immediately transformed into a 165-nanometer lithography machine, far exceeding the existing lithography technology!

In fact, immersive lithography is not the first to be created by Universal Corporation. However, the only Universal Corporation in the world is truly regarded as a research unit for a long time.

When the development of lithography technology develops from one generation to the next generation of technology, there will always be bottlenecks.

Therefore, as early as 1980s, some scientists used immersion technology to successfully improve the lithography effect. However, due to immersion lithography technology, its liquids are prone to contaminating optical lenses, so mainstream lithography technology research only uses it as a transitional means and does not pay attention to it. Once the next generation of lithography technology is mature, immersion lithography will be abandoned without hesitation.

But Universal Corporation is different.

Although researchers from precision instrument companies such as Wang Gong have tried their best, they are limited to the constraints of optical technology. They always lag behind the West in lithography machines.

If you are poor, you will change. If you change, you will be able to achieve success.

In order to improve the lithography accuracy, they used all the available technologies. Finally, after repeated research, they devoted their main energy to the research of immersion lithography technology without giving up on optical research, and have achieved great results in recent times.

They have developed a complete set of immersion technologies.

For example, liquids with different refractive indexes can be used to have a variety of immersion liquid materials ranging from 1:55 to 2.

Research on liquid foam, light transmittance, special photoresist, etc. that affect the photolithography effect has also achieved great success and has been initially practical.

Precision instrument laboratory has selected a special liquid as the main material for immersion lithography technology.

The refractive index of this liquid is as high as 17. Through experimental and technical improvements, its light transmittance can be fully applied to large-scale production.

As long as Wang Gong and others successfully transform the lithography machine, Universal will immediately obtain two sets of 145-nanometer ultra-high precision lithography machines. This alone can make Universal far ahead of the world level!

Universal has also provided the most stringent protection for this mature technology.

When they were keen on developing optical lenses with higher precision and neglecting immersive lithography technology abroad, they had already done a lot of work and accumulated rich experience.

In this way, even if foreign countries launch even more advanced lithography machines, they can immediately use immersion technology to surpass their competitors.

Moreover, the greater advantage of this technology lies in its cost.
