After some internal celebrations, the news of Vimicro's breakthrough in 14nm front-end lithography machine manufacturing technology was temporarily blocked.

Now is an extraordinary period, there is no need to stimulate the nerves of Europe, America, Japan and South Korea, and there is still a big gap between 14nm and the 7nm technology of the Netherlands, and there is really nothing to show off.

The next step is to sprint towards the peak of 10nm!

This is a watershed moment for cutting-edge lithography machines, and it also determines whether Xinghai Technology's AI chips can be realized.

Chen Xu naturally knows this, but there is no need to be so eager, anyway, there are still some important parts that are still in production.

The lithography machine was put aside first, and Chen Xu set his eyes on the robot.

On the afternoon of May 6, Chen Xu came to the Future Robotics Base located at No. 500 Loujiang Avenue in Sioux City Industrial Park.

In the huge dust-free workshop, thousands of industrial robots are making robots, and at a glance, there is not even a single human operator on the assembly line of thousands of square meters of workshop.

Chen Xu went to the workshop to look around, and Dr. Lin Zhiqiang, the technical director, told him about the production situation in the recent period.

When it comes to excitement, it's a pity.

Happily, Xinghai Technology has mastered the "core algorithm" of the robot.

In the past, the key indicators such as stability, failure rate, and ease of use of domestic industrial robots were far inferior to the products of the "four families" of industrial robots.

The gap between the core algorithms is too large, resulting in poor stability and a high failure rate of domestic robots.

The gap in the algorithm is not only reflected in the core controller, but also slows down the response speed of the servo system, because every time the robot completes an action, the core controller, servo drive and servo motor need to work together.

For a single servo system, the dynamic and static accuracy of domestic robots are very high, but high-end robots generally have more than 6 servo systems at the same time, and it is difficult to achieve good control results with traditional control methods.

Today, the core algorithm of Xinghai Technology has been officially listed, and it has won many awards in international competitions.

In Chen Xu's words, this is still the reason for the garbage of the main control chipset, if it is replaced with a top-level AI chip, Xinghai Robot will sweep the world!

But there are also sad points.

Xinghai's development in hardware is still very weak, such as the tactile sensors in industrial robots.

This is the core component of the sensor, and the requirements for accuracy and stability are very strict.

At present, most of the domestic sensor companies are engaged in the production of gas, temperature and other types of sensors, except for Xinghai Technology is researching and developing, almost no other sensor manufacturers are engaged in the production of tactile sensors.

Xinghai was previously imported from Japanese benzene, which is a leader in this regard, and their "array tactile sensor" can distribute 120 sensitive components in a substrate of 10 cm × 10 cm in size, and the price of one is as high as 120,000 yuan.

Most of the domestic products are "one-point type", generally 100 yuan each.

There are also some other accessories, such as high-end capacitor resistors.

The so-called high-end capacitance resistor, the most important thing is that the same batch should be as consistent as possible, and the Japanese benzene ...... The little Japanese Ben devil is indeed the best in this regard.

Compared with domestic enterprises, there is still a certain gap, and most of the products belong to the middle and low end, which is equivalent to "any dish will be fried, but there is no guarantee that every time it is fried, it is a taste".

Although there is no restriction on the import of this item, it is often necessary to wait for the goods in large quantities.

And Xinghai is now blacklisted, and the delivery date is far away, so the only way is to develop and produce it yourself, and then do it from other manufacturers.

"At the current pace of research and development, tactile sensors will not be produced and sold until the end of the year at the earliest. ”

"What about high-end capacitors and resistors?"

"The lab is only 13 percent complete, and it won't be known until two months. ”

Chen Xu nodded, and when he got out of the workshop, he remembered and asked, "Where did Lao Su go?"

Lin Zhiqiang said with a smile: "An old classmate of his, got married today, and went to have a wedding wine." ”

"His classmate is in his forties...... First marriage, second marriage?"

Standing next to Lin Zhiqiang, a beautiful girl in a dust-free suit "giggled" and said, "Boss, guess." ”

The girl's name is Guan Xiaomin, and she is a researcher in the Industrial Machinery Department.

In this industry where women are basically extinct, girls like Guan Xiaomin who love machinery and look beautiful at the same time are rare, so the company treats her better.

Chen Xu smiled and said, "Listening to your tone, is it difficult to get married for the third time?"

Guan Xiaomin was stunned when he heard this, and then said in surprise: "Wow~~~ Boss, you are too powerful." ”

"Stupid, your face has already told me what you have to say. Chen Xu laughed.

After a few jokes, Chen Xu raised his hand and looked at the smart watch on his left wrist, at 11:20, it was already time for dinner.

"Eat a piece at my house?"

"No, I'll eat at the company. Lin Zhiqiang declined Chen Xu's invitation, and then accompanied him all the way to the parking lot.

After Lin Zhiqiang sent Chen Xu away, he turned around and threw himself into the laboratory again.

……

Here, Chen Xu went back to Jinji Lake Villa for lunch and rested for half an hour, and then went to Xingsi Semiconductor Co., Ltd. in the Science and Technology Park.

I went here to check the research and development progress of packaging and testing software, and then returned to Zhonghai non-stop.

Passing by the Xinghai Institute of Chemical Materials in Minhang District, I went to see the research and development progress of "photoresist" and "microspheres", and plunged into the laboratory.

Although Chen Xu really wants to take a break, go to a sauna, soak in a hot spring, or find a girl to have a while.

But I don't know why, he feels like someone is pushing him behind his buttocks, and he can't stop for a moment.

Because he didn't understand a lot of things before, he could be a happy nouveau riche or a scumbag without a heart, anyway, when the sky falls, there is a tall man on top, and it's his business.

But not anymore, the more he learned, the more he felt the weight on his shoulders.

Whenever he wanted to stop and enjoy himself, countless industrial data flashed in front of his eyes like a flash, pricking every nerve in him, and then spurring him to keep running forward!

It's like "photoresists" and "microspheres".

These two are the key technologies that have been stuck by foreign countries in the subsequent chip development process.

Many people have heard of the name "photoresist", which is one of the key materials for the processing of fine patterns in microelectronics.

The main purpose is to transfer the pattern on the mask to the oxide layer on the surface of the silicon wafer, and to protect etching and ion implantation in the subsequent process, which is very, very important.

However, it is very unfortunate that almost all of China's LCD photoresists are imported, and the core technology has been ...... by TOK, JSR, Sumitomo Chemical, Shin-Etsu Chemical and other Japanese benzenes Monopolized by the Kohi Ben Devil Enterprise.

Take "BOE", which has a certain competitive strength in the world, as an example, the photoresist used for high-end panels is all provided by Japanese benzene companies.

it.

There are also "microspheres".

This thing may not be known to ordinary people, so to speak, microspheres are the bones of the LCD screen of mobile phones and the feet of chips.

The microsphere, which is one-thirtieth the diameter of a human hair, is the spacer that allows it to hold up two glass panels, equivalent to a skeleton, and then pour liquid crystals into the gap between the two glass panels.

In a mobile phone screen, 100 microspheres are used per square millimeter.

In addition, the chip is commonly used for solder connection, but now the chip is too small, and the pins are so small that they can't be seen clearly, and the conductive gold ball replaces the solder.

Microspheres with a diameter of several microns are mixed in an insulating adhesive to form an "anisotropic conductive film".

This film is attached between the chip and the motherboard, and the pressure is applied to the place where the pins need to be connected, and the small gold ball will conduct electricity between the two, which is now the standard method in the microelectronics industry.

Suffice it to say, without microspheres, chip production, food safety testing, disease diagnosis, biopharmaceuticals, environmental monitoring, ...... Many industries are in a quandary.

However, the fact is that in the field of microelectronics alone, China imports tens of billions of yuan worth of microspheres every year.

In 2021, China's domestic LCD panel shipments will reach 40% of the world's total, and the industrial scale will reach 130 billion US dollars, ranking first in the world, but the key materials in the panel, "spacer microspheres" and "conductive gold balls", all rely on imports.

And there are only two Japanese benzene ...... in the world. Konichi Benzoni subsidiary can provide.

beep-yes.

Chen Xu said that he didn't want to be stuck in the neck of Xiao Riben.

Together with Xiaobai, he designed and developed the "Macromolecule Reverse Thrust Engineering System", which analyzes the chemical materials of photoresist and microspheres in an attempt to find the best preparation process......
