The news is exciting!
After Chen Yao hung up the phone, he immediately rushed back to Jinglong Laboratory.
There is a transparent lens as big as the bottom of a pot in front of you. It is the optical lens of the photolithography machine.
There are 20 lenses installed in each lens.
The requirements for the lenses must be extremely precise and accurate. Chen Yaohe's team specially developed a new high-purity light-stealing material, coupled with fine polishing.
The top optical lens is finally available.
¡° If you want him to achieve high-precision lithography imaging, hardware alone is not enough, you also need algorithm support behind it.
This is the same as a camera. The camera is not powerful enough to take high-quality photos. The quality of the algorithm will affect the quality of the image.
Chen Yao coded himself, sitting in front of the computer and typing on the mechanical keyboard.
"Boss, you are using a black-axis keyboard. Aren't you afraid of hurting your fingers when typing?" Zhou Weiming came over and watched him code.
The next scene left him stunned.
Chen Yao¡¯s writing speed can be described as blazing fast. In the blink of an eye, there are 20 lines of code, and in the blink of an eye, there are another 20 lines of code.
Zhou Weiming didn¡¯t even see what code he wrote. He had already completed 300 lines.
Watching him code, the crazy speed of swiping the screen, full of pleasure!
In just 30 minutes, Chen Yao completed 23,000 lines of code and then packaged it.
¡°If Zhou Weiming hadn¡¯t seen it with his own eyes, he wouldn¡¯t have believed that there were such fast programmers in this world. There are really mountains beyond the mountains, and there are people outside the world and there is a sky outside.
¡°You don¡¯t believe there are geniuses in the world, it can only be said that you are short-sighted.

The photolithography machine lens technology has been broken, and other components will usher in a breakthrough.
In the next few months, Chen Yao trained talents while guiding the team to complete the research and development of other parts.
With his guidance, the members of Microscopic Jinglong have made rapid progress, and those who leave this unit in the future are worthy of pride.
The speed is very fast, and good news comes one after another.
A major breakthrough has been made in the light source technology of lithography machines, breaking the technical barriers in the United States and developing the world's most advanced extreme ultraviolet light.
When engraving on a nanometer-sized silicon wafer, a powerful and stable laser is crucial. This technology has been monopolized by the American Cymer company.
The light source developed by Chen Yao and his team has short wavelength, small size, high power and stability, and can be used to manufacture 5-nanometer chips.
? Continuous breakthroughs in technology have brought waves of pleasure!
The following month, sensor technology achieved a key breakthrough.
The interior of the lithography machine has very high environmental requirements for temperature and humidity, and the temperature change inside the machine must be controlled at five thousandths of a degree.
Exceeding the error will affect the focus accuracy of the lithography machine. Even if there is a slight error, the chip will fail.
Such high precision is simply abnormal.
A lithography machine will have more than two hundred high-precision sensors built into it to monitor data such as temperature, humidity, air pressure, etc. inside the machine.
In order to control the temperature change inside the machine within five thousandths of a degree, a very advanced cooling and heat dissipation system is required.
This request is not the most perverted, what is the most perverted?
There are two synchronously moving workpiece stages in the lithography machine, one for carrying negatives and one for carrying film.
The two must always be in sync with an error of less than 2 nanometers.
The two worktables moved from static to dynamic, and the acceleration was like missile launch.
There may be no concept in saying this, let¡¯s put it more vividly.
Its difficulty is equivalent to that of two large airplanes moving together from takeoff to landing. A knife sticks out from one plane and carves words on the grains of rice from another plane, making sure everything is exactly right.
Do you know why the photolithography machine is known as the most precise and most difficult instrument in the world? !
??Perverted, harsh, and unreasonable!
Today we humans can use smartphones. How much human wisdom and cutting-edge technology is behind them?
The last step is the most difficult. It requires extreme mechanical precision, and you cannot find such equipment produced in China.
Chen Yao led the team through many setbacks and failed many times. Some team members even felt frustrated and almost quit.
The situation is more difficult than expected. This kind of machine is not like a human being.It should be made.
Those days were Chen Yao¡¯s busiest days, spinning around in laboratories, factories, and colleges like a top.
On the one hand, we need to cultivate talents, and on the other hand, we need to participate in project research and development, design, testing, and even work as workers on the production line.
Fortunately, the most difficult period is finally over!
Chen Yao and the Micro Jinglong team successfully broke through the last difficulty!
At this point, all core components of the lithography machine have been domestically produced!
This is an amazing achievement!
The next step is assembly. The team hired Zhongxin International to complete the final assembly together.
The sales targets of lithography machines are chip foundries. As the best chip foundry in China, Zhongxin International must cooperate with them in the assembly of lithography machines.
Another advantage of doing this is that it allows their technicians to master the operation of the lithography machine as soon as possible.
Having a good machine is one thing, and operating it well is another.
Without high-quality talents, this kind of black technology machine cannot be controlled at all. The slightest deviation from the workers will lead to the failure of chip production.
In the morning, Chen Yao took a plane to Zhongxin International¡¯s chip factory in Zhonghai.
This is the largest wafer fab in the country and ranks among the top four in the world.
It¡¯s just that there is a huge gap with the three giants in front, which are Intel, Samsung and Semiconductor Manufacturing Company.
In fact, in terms of chip foundry technology, Zhongxin International is not much behind the giants. The key is that it has been strangled by the United States. It ordered ASML's lithography machine, but it has not been shipped for three years.
As soon as Chen Yao walked into the factory, exciting news came.
The Jinglong lithography machine developed by Huatian Microelectronics successfully passed the test!
Can be used as a 5nm chip!
Breaking the Western technology monopoly and making the world's top lithography machine!
What is exciting is that all core components are domestically produced and are completely independent of any other country.
Huaxia has become the only country in the world that can independently produce high-end lithography machines!
The number of patent applications exceeds 19,000, 98% of which are invention patents. Some technologies even surpass their opponents and become global leaders!
What makes Chen Yao most happy is that the research and development of photolithography machines has cultivated a large number of cutting-edge talents. The Micro Jinglong team has more than 2,800 people, and they are all technical experts in the semiconductor field.
"Captain, you're here!" Zhou Weiming rushed over excitedly and hugged him.
No words can describe the mood at this moment, Chen Yao and his brothers hugged each other tightly!
The whole team¡¯s brothers had tears in their eyes. This feeling was no less than winning a battle! (Remember the website address: www.hlnovel.com - Didn't finish reading?
