The technological empire begins with polymer materials

The next day came in a blink of an eye.

The test results were very gratifying. Kunlun Group’s optical system, including the most important objective lens, was lit up in one go and successfully taped out.

But at the same time, this experiment also found a lot of problems. Although the wavelength of the light source responsible for the Chinese Academy of Optoelectronics met the standard, it had the problem of too low power, resulting in insufficient exposure of the silicon wafer, even if the optical system gifted by the system was used. and super objective lens, there is no way to save it.

"How's the situation?"

Gao Yuan ran to take a nap, returned to the laboratory and yawned.

Chu Luoluo's face turned pale. This poor child was so excited and worried that she couldn't sleep well last night. But Gao Yuan was different. He not only slept comfortably, but also entered the system space to learn knowledge.

"We are still adjusting the light source. They are too slow. I think it doesn't work. Let's use our own light source!" Chu Luoluo was simple in mind and said immediately without thinking too much.

Gao Yuan frowned and looked at the laboratory where a group of engineers wearing white dustproof suits were debugging the light source generator. The entire test came to a standstill as everyone was waiting.

It seems that there is indeed a problem with their laser power, and it doesn't look like it can be solved in an instant.

Thinking of this, Gao Yuan walked into the project office.

Since it was a joint project, all the bosses were here, so there were many people in the office, and everyone looked very tired.

"Director Du." Gao Yuan said to Du Weiming from the Changchun Institute of Optics and Mechanics: "This time we brought an ultraviolet light source. If it doesn't work, let's test the ultraviolet laser first. The deep ultraviolet of the Institute of Optoelectronics will be tested later."

Gao Yuan brought a light source. He had already reported this matter, and everyone present knew it.

It's just that everyone is a little confused, what is an ultraviolet light source? Never heard of it before!

The light source made by optoelectronics is called ultraviolet, or deep ultraviolet laser, with a wavelength of 193nm. It is currently the most widely used in the world. This light source can be used from micron-level chips to 14nm chips.

Semiconductor foundry giant TSMC even used deep ultraviolet lasers to win the 7nm process, which shocked the world and completely established its reputation as the No. 1 Tianwang Mountain in the semiconductor field.

Therefore, when the Institute of Optoelectronics of China tested the deep ultraviolet light source, Gao Yuan had no objection at all. Although this kind of light source cannot produce top-notch craftsmanship, it is cheap and cost-effective. It does not mean that after Gao Yuan takes out the ultra-violet light source, the deep ultraviolet light source will no need.

A qualified photolithography machine should be compatible with several light sources and processes at the same time, so Gao Yuan asked the Zhongke Optoelectronics Institute to test deep ultraviolet light first, and planned to wait for them to complete it before testing its own ultraviolet.

Unexpectedly, the Institute of Optoelectronics made no progress all day long. This made Gao Yuan a little bit unbearable, and asked the engineers of the Institute of Optoelectronics to take a break. People are like this sometimes, getting busier and busier, and it is hard for everyone to get some sleep. Take a hot bath, enlightenment suddenly, and the problem is solved.

Du Weiming frowned and said: "It will probably take more than half a day to remove the light source generator and replace it with yours. Why don't you wait any longer? The light source is not a light bulb. It is very troublesome to replace it, and every time it is removed, Installation, the accuracy needs to be calibrated again.”

What Du Weiming said is true. The photolithography machine is not a sewing machine. It cannot be disassembled and disassembled all day long. If it is moved even slightly, the accuracy will have to be recalibrated, which is very troublesome.

When Gaoyuan arrived, the deep ultraviolet light source of the Institute of Optoelectronics had already been installed on the test machine, otherwise Gaoyuan would have asked to test its own light source first.

However, this conversation made Dean Gong Xinying of the Optoelectronics Institute turn red and white, making him unable to sit still.

They are all engaged in scientific research. Although Dean Gong has always admired Kunlun Group, this is too hurtful!

It seems that it was just because it was too troublesome that I reluctantly let my light source stay on the machine. If it were easy to disassemble and assemble, I would have removed my light source and thrown it away!

Are you okay?

Then come on!

Ultraviolet laser?

What a joke!

Could it be stronger than the extreme ultraviolet of ASML in the Netherlands? ?

You know, ASML has reached a wavelength of 13.5nm, while traditional deep ultraviolet light is 193nm. There is an essential difference between the two light sources!

I don't believe it!

This ultraviolet light from your Kunlun Group can also achieve 13.5nm?

I'm afraid it's just a name!

Kunlun Group has always been keen on publicity, giving its products and technologies some incredible and weird names.

It's obviously a solid-state battery, but it's called Kunlun crystal.

It's obviously composite carbon fiber, but it's called Kunlun Dark Star.

The most outrageous thing is the mechanical exoskeleton, actually called the Atomic Ant?

Who do you think you are?

Marvel’s superhero Ant-Man?

Dean Gong had a gloomy face, and many thoughts flooded into his brain in an instant.

It’s not that anyone who does scientific research hasn’t got a little weird about the plateau? Before he finished his experiment, Gao Yuan rushed to replace him, which really made him lose face.

"Director Du, since Boss Gao has a more advanced light source, take down ours and put them in their place." Dean Gong frowned and said in a deep voice.

"There's no rush, no rush, both light sources need to be tested, so let's finish yours first." Du Weiming saw that Dean Gong's expression was not good, so he hurriedly smoothed things over.

"It doesn't matter, we are engaged in scientific research, and whoever has the ability always gets the job. I will let people do it and remove the light source."

Dean Gong couldn't help but leave the office and ordered his men to dismantle the laser generator.

The engineers at the Optoelectronics Institute were shocked. Why were they dismantled before the test was completed?

When they heard that it was to make way for the Kunlun Group, the engineers suddenly lost their temper. Who could let this person have great ability and a beautiful optical system? The accuracy of that set of objective lenses is said to be perfect within one nanometer.

Despite this, the engineers at the Institute of Optoelectronics are still a little unconvinced. After all, just because the optics are good does not mean that the laser can also do it.

When the time came at night, the deep ultraviolet laser emitter had been dismantled and replaced with an ultraviolet laser emitter brought by the plateau. The engineers worked hard and spent a whole day to complete the replacement and calibration of the light source.

Hey~

It doesn’t matter if it’s a bit hard, just hope for good results.

Ultraviolet?

The name is quite interesting, but I don’t know what the wavelength is and what the power is?

Dutch ASML has achieved these two most critical parameters to a level rarely seen in the world. The wavelength is only 13.5nm, and the power has reached 250w. When used to expose silicon wafers, the efficiency cannot be exaggerated.

If only Kunlun Group could use half the standard of Dutch ASML, thank God.

Bang~

As a laser blasted out, the machine lit up again, and the process went very smoothly.

After a while, an engineer wearing a white dust-proof suit held up a twelve-inch silicon wafer with trembling hands and placed it under the light to examine it.

Countless mysterious and complicated lines are like the most wonderful works of art in the world, which are fascinating.

"Light up again!?"

"This is so lucky!"

"What's the wavelength? What's the power?"

"I don't know. The specific parameters are in the control room, but I see that the wafer exposure seems to be much better than before."

The onlookers were talking a lot, and at the same time, there was a noise from the control room, as if a wild beast had entered the control room, causing a lot of chaos inside.

"what's the situation!?"

"They seem happy?"

"Maybe the parameters are relatively good, so they are more excited."

Everyone outside didn't know what was going on, and looked at the control room with curious eyes.

After a moment, the engineer wearing glasses pushed open the door and walked out. He held up a form with parameters written on it as if he was holding up a victory trophy.

"Wavelength 1.5nm!"

"The power is exactly 2000w!" The glasses engineer's eyes were red and he shouted at the top of his lungs: "Kunlun Group! Awesome!!!"

It was so difficult to write these two chapters. Although I am a computer major and I did work in the technology circle before writing the book, I have never seen such a high-level existence as a lithography machine. In addition, I don’t know much about software. I don’t quite understand, these are all facts.

In short, I will try my best to let everyone understand some technology-related information while reading the book. Knowing more things in this life is never a bad thing.

In addition, Chapter 241 has been blocked again. If you can't find an editor at this time, you will have to wait until tomorrow.
