Let you recycle scrap metal and bring back a 10,000-ton battleship

Chapter 133 My Idea Is Simple!Build your own chips!
"Hahaha, did you see it?"

"Old Wang, many countries really want to buy our filter membrane and soaking solution!"

"For these people, sewage treatment has always been a problem!"

"But as Xiao Luo said, of course foreigners have to pay a higher price!"

In Long Jianfei's office at Modu Military Industry, Wang Bozhao from the Customs came rushing through 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 became emotional.

And they knew that all of this was due to Luo Feng and the team behind him.

Without them, we definitely wouldn't be where we are today.

"Little Luo is great. When I found out about the filter membrane factory, I thought it was a little too much to get a statue for Xiao Luo. But now, looking at the reaction of the whole world, I think he deserves it!"

Wang Bozhao also said with relief, and the two of them began to chat about the recent frequent domestic happy events.

But soon, Long Jianfei's phone rang.

When he saw that it was Luo Feng calling.

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

"Hello, Xiao Luo."

"Old Long, hello, I'm sorry, I'm here to disturb you again!" Luo Feng said with a smile when he saw that the phone was answered within a few seconds.

"Hehe, what are you talking about? Why are you bothering me? You call me only to disturb me. I hope this kind of disturbance, come and trouble me every day." Seeing this, Long Jianfei, who was in a good mood, naturally laughed.

Every time Luo Feng took the initiative to contact him, good things happened.

So who wouldn't like such an interruption?
"Old Long, I want to ask some questions!"

"you say!"

"Exactly. If I want to invest in a fab, what procedures do I need to go through? Is it complicated?"

Seeing Luo Feng's question, Long Jianfei was stunned for a moment, "What? Xiao Luo? You want to build a wafer manufacturing plant?"

At this moment, his face completely changed.

I feel like I heard it wrong.

"Sorry, Xiao Luo, I lost my temper!" But Long Jianfei immediately thought that it was not someone else who said this, but Luo Feng, and then he calmed down a bit, and asked, "Xiao Luo, are you talking about wafers? One of the raw materials for chips?"

"Yes!" Luo Feng nodded with certainty.

"Then do you know the meaning of this thing?"

"I know, a wafer is a single crystal silicon wafer, which is refined from silicon sand, a semiconductor material, and a chip material!" Luo Feng answered so much knowledge in an instant.

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

Instead, I think, can Luo Feng handle such a thing?
Of course, the manufacturing specifications of wafers are also divided into 4 inches to 8 inches, but in recent years, larger specifications of 12 inches have emerged.

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

But the production technology is extremely strict.

"Actually, Xiao Luo, the first 12-inch wafer recycling factory in our country has already been put into operation. Although the output is not too much, but"

Luo Feng coughed immediately when he heard this, and interrupted: "Mr. Long, you must have heard the truth. What I want to do is not a wafer recycling factory, but a direct manufacturing, which is a first-hand product!"

Regeneration and self-creation are two different things.

Wafer regeneration, which is a process of reusing the scraps of wafers.

For example, the area of ​​a 12-inch wafer is about 7 square millimeters. Taking a 7NM chip as an example, if it is 700% cut, then about [-] chips can be obtained.

However, considering the yield rate and the shape of the wafer, it is impossible to have a 500% utilization, and the actual chip is only [-] yuan, which is not bad.

Therefore, at the same time, there will be about 10% to 20% of the wafer scraps left.

As Long Jianfei said just now, the wafer recycling factory specializes in processing these scraps and then reusing them.

Wafer regeneration factory is to save production cost, which is a very important link in 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, I am of course very happy, but the investment for this thing is not small, and the more important thing is that there must be talents in this field." Long Jianfei asked curiously, "By the way, Xiao Luo, how many nanometers of technology do you plan to use?"

Speaking of this, the most critical question, 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, as many people know, is not very optimistic.

For example, domestic Huawei mobile phones are very powerful in the field of chip computing. We have launched 3nm-level chips for the Hai and Lin series chips very early.

However, under the ban, top chip manufacturers such as Samsung will not OEM for Huawei, and our most advanced chip manufacturers will be powerless.

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

In addition, there are news that domestic 28nm chips will be mass-produced this year, and 14nm chips will be mass-produced next year, as well as Huawei's disclosed "dual-core stacking" patent, where two 14nm chips are stacked together, and the performance is comparable to 7nm chips.

Even so, but to put it bluntly, compared with the top nm technology abroad, it is still a lot worse.

Especially for Huawei's Kirin chip, even if its research technology has reached the world's leading level, the flaw is that it needs to rely on foreign advanced lithography machines.

After all, the lithography machine developed by ourselves can only successfully engrave lines with a line width of 9nm. For that top-notch chip, such a machine is powerless.

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

Luo Feng's words shocked Wang Bozhao, who was drinking tea, "Xiao Luo, is what you said true?"

"Yes, Xiao Luo, this seems unlikely, 5nm technology?" Long Jianfei was also surprised, his face pale.

"Of course! What I said is true!"

Luo Feng's voice fell.

The two looked at each other, and then, Long Jianfei didn't care too much, "Xiao Luo, wait for us, we will fly over to Hangzhou, and have a good talk with you in person!"

"Ah? That's fine!"

Luo Feng hung up the phone, feeling a little speechless about Long Jianfei.

Is this too urgent?
In addition to producing wafers, fabs can also directly manufacture chips.

But with different equipment and manufacturing processes, there is a big gap in 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 various reasons, we have not been able to realize it.

As for the higher level, Luo Feng naturally took it out without any intention. This thing can't be done overnight, it has to be done slowly.

Otherwise, on the Tianyuan planet, this thing can't be called a chip.
It's like the battleships are the rich yachts over there.
In the afternoon of that day, Luo Feng received a call from Zheng Zeyao, who was also in Hangzhou on vacation these days.

It is estimated that Long Jianfei and the others came over, so they called Zheng Zeyao together.

It was still the coffee shop that Luo Feng was more familiar with, the Old Tree Cafe.

This is the place where I usually meet Zheng Zeyao in my hometown Luofeng.

Of course, this time it wasn't just Zheng Zeyao and Long Jianfei who came over, there was also a man wearing glasses who was more gentle and bookish.

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

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

At the very least, this little doctor in his thirties probably wouldn't know.

"Little Luo! Let me introduce you!"

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

After speaking, Long Jianfei looked at Ji Shunqing, "Shunqing, this is Mr. Luo! I told you about the situation, so you can introduce yourself to Mr. Luo!"

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

"Yes!"

"And you're going to manufacture at the 5nm level?"

"Yes!" Luo Feng nodded without hesitation.

On the other hand, Ji Shunqing didn't know what to say. After a bitter smile, "Mr. Luo, do you really understand this industry?"

"I have checked some knowledge on the Internet, it can only be regarded as a preliminary understanding!"

Hearing this, Ji Shunqing also wanted to laugh. Fortunately, he is of high quality, so naturally he won't show his inner thoughts.

He just smiled slightly and said, "Mr. Luo, do you know that let alone a 5nm chip, even a 7nm chip, we can't get the corresponding equipment. Without the corresponding equipment, even if we have the relevant knowledge and talent, we will be eaten by tigers, and we will have nothing to eat!"

"You mean, I can understand that there is a lack of photolithography machine?"

In fact, if you want to talk to an expert, it is generally easier to understand, but Luo Feng is a beginner who just checked the information all night, so naturally he doesn't understand many things very well.

So I opened my mouth and asked.

But just asking this question, the other party seemed to be unable to bear it anymore, and burst out laughing, but it was just a sneer.
