Wang Xueba System

In addition to the newly invented alloy, Luo Hao is also working on several other technologies.One is the lithography machine technology that is now the main reason for relying heavily on chips from the beautiful country.

The cpu of the mobile phone and the cpu of the computer are in the lithography machine, and Xia Guo has been lagging behind in the manufacture of high-precision chips.Until now, Xia Guo's self-developed lithography machine can only support 14nm chip production at most.This was recently produced by a technology company after many years of research.

However, in terms of current mobile phones and computers, the CPU level used has basically broken through to single digits, and the chips of mobile phones can even reach the highest 4nm level.

And the mobile phones and computers produced by these chips have a large sales volume in Xia Guo, a country with a large population.Although the number of chips that the country can use at this level is not much compared to the number needed by ordinary people, in some special fields, Xia Guo still needs to make its own security chips to ensure the confidentiality of its own data. In addition, Once the beautiful country raises the prices of the major electronic manufacturers in the Xia country, it will also be a huge blow to the Xia country's economy.

The most intuitive phenomenon is that Xiaguo's mobile phones and computers will not meet the needs of today's use. Everyone can only accept expensive prices to buy new mobile phones, or they can only buy some mobile phones that were a few years ago or even more than ten years ago. Mobile phones and computers, or can only buy machines of other national brands.

Some heavy industries in Xiaguo will be greatly affected without cash chip support, and even cause development to stagnate.

The reason why Luo Hao wants to study this technology is also because the core technology of this lithography machine is somewhat related to the 5g signal anti-jamming technology that he has studied before.

Light waves are also a type of electromagnetic waves.Among the four most critical technical difficulties in lithography machines, two are related to light-light source and purification spectrum.

The light source mainly needs to produce short-wavelength light that can be fully controlled.What is stuck in Xia Guo now is how to produce continuous and controllable short-wavelength light. Moreover, the shorter the wavelength of light, the higher the accuracy. Produce a light source with a shorter wavelength than the light source used in the beautiful country, and now the most advanced light wave in the world is the extreme ultraviolet in euv, and its wavelength is only 13.5 nanometers!

Don't think that 13.5 nanometers is very big. You must know that the diameter of human hair is about 8000 nanometers!

And the beautiful country produces this kind of extreme ultraviolet light by using a carbon dioxide laser with a power of 250 to continuously bombard the dripping metal tin droplets. After continuous bombardment, euv plasma can be excited to obtain light with a shorter wavelength. .In this process, about 5 droplets are attacked per second, and a metal tin droplet is actually only 20 microns in size.

And this is enough to see why the light source has become a major problem hindering the development of Xiaguo lithography machines.

Another piece of the puzzle is mirrors.

The function of the mirror is to scale down the circuit diagram on the template and present it in the form of a circuit diagram on the silicon wafer, which is a key component for manufacturing chips.The mirror used in the lithography machine is actually a coated mirror, which will screen the spectrum during reflection, and multiple reflections can better purify the spectrum and obtain euv that meets the requirements.

The reason why the reflector becomes a problem is because the light is reflected many times, and because of the precision of the mirror surface, the light source will be attenuated, and if you want to get a light source that meets the requirements, you need to improve the precision of the reflector !

In a word, how high is the accuracy of the euv mirror?Assuming that a mirror with a diameter of almost half a meter is as large as the land of the country of beer, its local unevenness cannot exceed 1mm.

At this moment, due to technological limitations, if Luo Hao wants to overcome this problem, he must create a new method. One is to produce a light with a sufficiently small wavelength, and the other is to find and create a process to produce Reflectors sufficient to meet the conditions.

Looking at the experimental results in front of him, Luo Hao smiled.

A new method of producing extreme violet light has been created, with a wavelength of only 10.5 nanometers!

This is what Luo Hao has been researching since he made a new type of metal, and the next step is to break through the manufacturing process of the second reflector.

"But this is not that important. The country of beer also has such things as reflectors, and the craftsmanship has always been leading in the world." Luo Hao touched his chin, "Research and study first, and talk about it if we can't make it, otherwise it will really affect me. Make the operating table of the lithography machine behind."

After thinking about it, Luo Hao operated on the computer in the laboratory for a while, then sat in the laboratory and waited quietly.

Soon, a batch of experimental materials were sent over, along with a mobile hard disk, which contained the materials made by the reflector.

"Huh..." After thanking Luo Hao and the staff who delivered the materials, he stretched his waist, "It's time to learn something new again!"

Soon, Luo Hao was immersed in study and research again.

............

On the other side, Xia Guo's announcement has been sent out.

"Xiaguo actually has anti-jamming technology?" Bai Deng frowned. If this is the case, then it makes sense that the signal jammer didn't take effect before.

"Hansen, what happened to the matter you were asked to investigate earlier?" Bai Deng asked suddenly.

"There is no news, and no one can tell who made the 5G communication technology." Hansen said, "This has already used all our ordinary intelligence personnel, and some special intelligence personnel have not received the news."

"Is it so secret?" Bai Deng frowned, "So, the biggest possibility is that this technology was created by Luo Hao?"

"Yes, this is the only possibility, and this anti-jamming technology is probably invented by Luo Hao." Hansen nodded, "In addition, according to the news from the technical department, Xia Guo was in the The storage technology demonstrated during the test in Romantic City is also very powerful, and our beautiful country should not have such a strong writing speed."

"Could it be that Luo Hao created this too?" Bai Deng frowned even tighter, "I said to investigate Luo Hao's recent formation, how is it going?"

"Luo Hao hasn't come out from Fuxing Academy recently. He is probably doing some experiments. According to our investigation, he basically stayed in the laboratory all the time."
