Technology company, I will become the light of China!

Chapter 77 One dares to brag, but a group dares to believe

Under the leadership of Gao Yongming, the access control of Loongson International was also opened one by one, and they came to the changing area.

If you want to enter the area where the photolithography machine is located, you must change into dust-free clothing.

The more precise the machine, the more it requires a highly clean environment. Even if we know that the photolithography machine is not that fragile, with the technical conditions of the Dragon Kingdom, we simply cannot afford it.

Because once there is a problem with the lithography machine, you can’t find anyone to repair it. You can only ask the original manufacturer to send an engineer, or send the lithography machine back. Either way, the cost of repair is as high as tens of millions.

It is necessary to wear dustproof clothing to avoid potential risks

Gao Yongming, two Loongson International executives, as well as Chen Xing, Qu Cheng, and Lin Tian were all neatly dressed, and after being thoroughly disinfected and disinfected, they entered the lithography machine area.

“please come with me”

Gao Yongming leads the way

When everyone passes through the corridor of about 20 meters, the access control system automatically recognizes and opens the glass isolation door

After passing through several gates in a row, Chen Xing finally saw the photolithography machine.

Different from the reduced pictures on the Internet, the real-life photolithography machine looks like a small passenger vehicle.

It is about six meters long, three meters wide and three meters high. The overall appearance is like a huge white container. Inside, there are more than 100,000 precision parts produced by advanced countries around the world and assembled by the Dutch ASML company.

Gao Yongming also stepped forward and explained to everyone:”This is a 28-nanometer process DUV lithography machine. It uses a deep ultraviolet light source with a wavelength of 193 nanometers. It can 28 nanometers, 34 nanometers, 48 nanometers and above at one time. Nano-process chips have been exposed and are currently the mainstream machines produced by our Loongson International.”

“If you want to produce 20nm chips, the accuracy and resolution of this 28nm process lithography machine are not enough, and you need to use a more advanced 20nm process lithography machine.”

“Everyone, please continue to follow me.”

Gao Yongming briefly introduced the 28nm process lithography machine and continued to lead the way. Chen Xing and others followed for another twenty meters and passed an access control.

When entering the area of another lithography machine, Chen Xing couldn’t help but be amazed. This lithography machine occupies a large area.

The height may be four meters, the width may still be three meters, but the length is at least seven meters, or even eight meters!

With such a huge volume, the shock-absorbing platform and steel structure shell of this photolithography machine must have been comprehensively upgraded.

When Gao Yongming looked at this huge lithography machine, his eyes revealed a touch of pride, and he solemnly declared:

“This one! It is our latest order from the Dutch ASML company, a 20-nanometer process DUV lithography machine, priced at 220 million per unit. With it, Loongson International has officially entered the ranks of 20-nanometer chip foundry companies.”

20nm chip foundry, which is barely keeping pace with the world

If independent mass production can be achieved, Longguo’s mainstream 28nm chips may have to be upgraded to 20nm.

A small step for Loongson International, but a big step for the development of Longguo Chip

When Chen Xing heard about the price of a lithography machine, he couldn’t help but marvel. If you buy a lithography machine for 220 million, you still need to explore the process technology yourself. The chip industry is indeed not something ordinary companies can play.

With such a harsh operating environment, even if you don’t invest hundreds of millions of dollars to build it, even if you have a photolithography machine, it will be useless.

The lithography machine is no different than other machines. It is too delicate. Any interference may affect the light source of the lithography machine, thus affecting the final production.

Qu Cheng grasped the key point and asked in confusion:”You mean Loongson International has just entered 20 nanometers, so what about 14 nanometer chips?”

“Ah…this…”

Gao Yongming is a little messy in the wind

He wants to say something now, you didn’t say you were going to make 14nm chips when you came here!

At this time, the Loongson International engineer standing next to Gao Yongming spoke.

“Qu Lao, the machine we purchased is a DUV lithography machine. Its light source is deep ultraviolet light with a wavelength of 193 nanometers. It is not an EUV lithography machine and cannot emit extreme ultraviolet light with a wavelength of 13.5 nanometers. We want to manufacture 14nm chips, maybe…well…there is still some distance”

loadAdv(7,3);

“Can’t make it?”

Qu Cheng was stunned, and then said doubtfully:”That’s not right, Feng Chengming said last time that you have put 14nm on the agenda.”

Feng Chengming, chief engineer of Loongson International, is also an academician of Longxin Academy of Sciences

Gao Yongming:”……”

Case solved!

He knew someone was bragging!

One dares to brag, the other dares…

No!

How dare he trust a group of academicians!!!

Two Loongson International engineers also realized that they finally understood why Chief Feng Chengming said he felt unwell overnight and went to the Imperial Capital to see a doctor.

After Xunsiyou finished bragging, he ran away first?

Gao Yongming and the two engineers are very embarrassed. Now they don’t know how to explain it, especially the Qu Cheng they are facing.

Chen Xing secretly frowned. He looked at the three people hesitating at Loongson International and seemed to vaguely guess something.

And judging from what they said, if there is no EUV lithography machine with a wavelength of 13.5 nanometers, then 14 nanometer chips cannot be manufactured. Is this trip in vain?

Qu Cheng, whose face was ashen on the side, had already cursed Feng Chengming hundreds of times in his heart. No wonder he posted on WeChat Moments overnight saying he was not feeling well and wanted to go to the imperial capital to recuperate. He was thinking, are you bragging?

Just blow it!

He also deceived a group of academicians!

Qu Cheng can’t get off the stage now. It’s really embarrassing.

Originally, they wanted to choose TSMC as an OEM, but these old guys asked Chen Xing to choose Loongson International under the guise of a guarantee. In the end, they didn’t even have suitable photolithography equipment?

What a shame!

I’m too embarrassed to see anyone!

Qu Cheng’s face was livid and his cheeks were still a little hot. If he had to choose again, he would let Wang Jirong come.

At least it’s embarrassing for him, not Qu Cheng’s face…

“In other words, Loongson International can only OEM 20nm chips at present, right?”

Chen Xing breaks the awkward atmosphere

Although a day or two was wasted, it doesn’t matter. It’s all about giving face to the academicians. After all, without them, Qingzhou’s 14nm processor chip would not have been designed so quickly.

If Loongson International doesn’t work, then look for other foundries.

“Still…there’s still a little distance…”

An engineer tremblingly replied

From 20 nanometers to 14 nanometers, you would say it is a little distance, right?

Chen Xing sighed slightly. Without an EUV lithography machine with a wavelength of 13.5 nanometers, even if there were red-quality lithography talents, it would probably not be effective.

Let him rub his hands?

There’s no way he can get an EUV lithography machine out, right?

Listening to everyone’s conversation, Lin Tian fell into silence. He didn’t expect that Longguo’s equipment foundation was so poor. It didn’t even have an EUV lithography machine. Was it too restricted?

“well!”

Chen Xing sighed. He didn’t hesitate and smoothed things over for Qu Cheng and Gao Yongming:

“It seems that our chip companies in Longguo still need to work harder, but this time it is not in vain. You can visit the lithography machine up close, and you can also���Seeing the gap with the West, we can catch up in the future”

After the steps were set up, Qu Cheng and Gao Yongming naturally wanted to go down the stairs.

However, before they could speak, Lin Tian said to Chen Xing in a serious tone:”If the president needs it, the 20-nanometer DUV lithography machine can produce 14-nanometer chips through multiple exposure technology, but it requires a lot of effort. Several times the cost of tape-out”
