"Hahaha, do you see?"

"Lao Wang, many countries are very eager to buy our filter membranes and soaking liquids!"

"These people, sewage treatment has always been a problem!"

"But what Xiao Luo said, of course foreigners have a more expensive price!"

In the office of Long Jianfei in the military industry of the magic capital, Wang Bozhao of the customs came to the door again.

The two of them simply drank tea and chatted.

But when it comes to the recent desalination of seawater, both of them are in high spirits.

And they knew that all of this had to come from Luo Feng and the team behind him.

Without them, there would be no today.

"Xiao Luo is very great, when I knew about the filter membrane factory, I directly made a statue of Xiao Luo, I think it was a bit too much, but now it seems that the reaction of the whole world, I think he deserves it!"

Wang Bozhao also said with relief, and the two began to talk about the frequent happy matters in China recently.

But soon, Long Jianfei's phone rang.

When I saw that it was Luo Feng calling.

Long Jianfei immediately raised his index finger and made a silent gesture.

"Hey, Xiao Luo."

"Hello Long Lao, I'm sorry, I'm bothering you again!" Luo Feng saw that the phone was answered in just a few seconds, and said with a smile.

"Hehe, what's the matter, what are you bothering about? If you call me, it's all a disturbance, and I hope that this kind of interruption will bother me every day. Seeing this, Long Jianfei was in a good mood, so he naturally laughed.

Every time Luo Feng took the initiative to contact him, it was a good thing to happen.

So who wouldn't love such an interruption?

"Long Lao, I want to ask some questions!"

"You say!"

"That's it. If I want to invest in a fab, what do I need to do? Complicated or not? ”

Seeing Luo Feng ask, Long Jianfei was stunned for a moment, "What?" Xiao Luo? You're going to get a wafer fab? ”

At this moment, his face completely changed.

I don't think I've heard it wrong.

"I'm sorry, Xiao Luo, I lost my temper!" But Long Jianfei immediately thought that it was no one else who said this, but Luo Feng, and then his mood eased a little, and asked, "Xiao Luo, are you talking about wafers?" One of the raw materials for that thing? ”

"Yes!" Luo Feng nodded affirmatively.

"Do you know what this thing means?"

"You know, the wafer is a monocrystalline silicon wafer, which is refined from silica sand, semiconductor materials, and chip materials!" Luo Feng made up so much knowledge and answered in an instant.

Of course, Luo Feng knew that the other party didn't want Luo Feng to popularize science.

But I think, can Luo Feng handle such a thing?

Of course, wafer manufacturing specifications are also divided into 4 inches to 8 inches, but in recent years, larger specifications of 12 inches have come out.

The larger the wafer, the more ICs can be produced on the same wafer, which can reduce the cost even more.

However, the production technology is extremely strict.

"Actually, Xiaoluo, the first 12-inch wafer recycling factory in our country has been put into operation, although the output is not too much, but"

Luo Feng immediately coughed when he heard this, and interrupted: "Old Man Long, you can really hear it, what I want to do is not a wafer recycling factory, but a direct build, it is first-hand goods!" ”

Regenerating and building oneself are two different things.

Wafer regeneration is a process in which wafer scraps are reused.

FOR EXAMPLE, THE AREA OF A 12-INCH WAFER IS ABOUT 70,000 SQUARE MILLIMETERS, SO TAKING A 7NM CHIP AS AN EXAMPLE, IF IT IS 100% CUT, THEN ABOUT 700 CHIPS CAN BE OBTAINED.

However, considering the yield rate and the shape of the wafer, it is impossible to have 100% utilization, and it is actually possible to get 500 chips, which is good.

Therefore, at the same time, there will be about 10 to 20 percent of the wafer scraps, which will remain.

As Long Jianfei said just now, the wafer recycling factory is dedicated to processing these leftovers and then using them.

Wafer recycling factory, which is to save production costs, is a very important link in the chip manufacturing industry.

"Direct manufacturing?" Long Jianfei was stunned, and said with a bitter smile, "Xiao Luo, if you want to directly invest in manufacturing, of course I am very happy, but the investment in this thing is not small, and more importantly, there must be talents in this area." Long Jianfei said, and asked curiously, "By the way, Xiao Luo, how much nm process do you plan to use?" ”

Speaking of this, when the most critical question came, Long Jianfei at this moment also began to look forward to it.

Although, now we also have a wafer fabrication plant.

But the specific situation, in fact, many people also know, is not very optimistic.

For example, the domestic Huawei mobile phone is very powerful in the field of chip computing, and we launched the 3nm level of the Hai and Lin series of chips very early.

But after being banned, top chip manufacturers such as Samsung will not be foundry for Hua Wei, and our most advanced chip manufacturers will not be able to do anything.

Although Hua Wei also built its first wafer fabrication plant, the domestic 28nm wet process equipment and domestic thin film deposition equipment entered the 14nm production line.

And there are also domestic 28nm chips mass production this year, 14nm chip mass production next year, and what "dual-core superposition" patent disclosed by Hua Wei, two 14nm chips are superimposed together, and the performance is comparable to 7nm chips and so on.

Despite this, it is not good to say, compared with the top NM process abroad, it is still much worse.

Especially Hua Wei's Kirin chip, even if the research technology has reached the world's leading level, the flaw is that he needs to rely on advanced lithography machines from abroad.

After all, the lithography machine we developed ourselves can only successfully carve out lines with a line width of 9nm, and there is nothing we can do about that kind of top-notch chip and such a machine.

"I can't be sure yet, but at least it's a 12-inch wafer production line, and a 5nm chip process!"

Luo Feng's words directly made Wang Bozhao, who was drinking tea on the side, startled, "Xiao Luo, is what you said true?" ”

"yes, Xiao Luo, this seems unlikely, 5nm process?" Long Jianfei also said in surprise, his face pale.

"Of course it's certain! What I'm saying is true! ”

Luo Feng's voice fell.

The two of them looked at each other, and then, Long Jianfei couldn't care so much, "Xiao Luo, you wait for us, let's fly over to Hangzhou and talk to you in person!" ”

"Huh? All right! ”

Luo Feng hung up the phone, and he was a little speechless about this Long Jianfei.

That's too much of a hurry, isn't it?

Wafer fabs, in addition to being able to produce wafers, can also directly manufacture chips.

However, there is a big gap between different equipment and manufacturing processes and the level of chips that can be manufactured.

The 5nm manufacturing process is already the best in the world.

In fact, we wanted to introduce such process equipment and technology at the earliest, but due to general reasons, it has not been realized.

As for the more advanced, Luo Feng naturally took it out without any intention, this thing can't be done overnight, you have to take it slowly.

Otherwise, on the Celestial Origin Planet, this thing can't be called a chip

For example, the warships are all rich yachts over there

In the afternoon of the same day, Luo Feng received a call from Zheng Zeyao, who was also on vacation in Hangzhou these days.

It is estimated that Long Jian flew over with them, and they called Zheng Zeyao together.

It's still the café that Luo Feng is more familiar with, the Ancient Tree Cafe.

When Luo Feng and Zheng Zeyao meet in their hometown, they are usually in this place.

Of course, this time it was not only Zheng Zeyao and Long Jian who flew over, but also a man with glasses, who was more elegant and bookish.

When he saw Luo Feng, he couldn't hide the suspicion on his face.

For Luo Feng, there are not many people who have made a lot of contributions, in fact, there are not many people who know about it.

At the very least, this little doctor in his thirties should not know.

"Xiao Luo! Let me introduce you! ”

Seeing Luo Feng and Zheng Zeyao sitting opposite, Long Jianfei spread his hands towards the little doctor beside him, "This is our Loongson expert, whose name is Ji Shunqing." ”

As he spoke, Long Jianfei looked at Ji Shunqing, "Shunqing, this is Mr. Luo!" I told you about the situation, you can introduce it to Mr. Luo yourself! ”

Seeing this, Ji Shunqing nodded slightly and said, "Hello Mr. Luo, I'm Ji Shunqing, I heard that you plan to invest in a wafer factory and make chips, right?" ”

"Yes!"

"And you're going to make a 5nm class?"

"Yes!" Luo Feng nodded without hesitation.

On the other hand, Ji Shunqing didn't know what to say, and smiled bitterly, "Mr. Luo, do you really understand this industry?" ”

"I've checked some things on the Internet, so I can only be regarded as a preliminary understanding!"

Hearing this, Ji Shunqing also wanted to laugh, fortunately, the quality is very high, so naturally he will not show his inner thoughts.

He just smiled and said: "Mr. Luo, do you know, let alone a 5nm chip, even if it is a 7nm chip, we can't get the corresponding equipment, there is no corresponding equipment, even if there is relevant knowledge and talents, it is a tiger, and there is no way to eat it!" ”

"What do you mean, I can understand that there is a lack of lithography machines?"

In fact, if you want to speak in an expert, it is generally easier to understand, but Luo Feng belongs to the preliminary beginner who checked the information all night, and naturally he doesn't understand many things.

So I asked.

But as soon as he asked like this, the other party seemed to be unable to hold back any longer, and laughed out loud, but it was just a sneer.
