Chapter 133 My Idea Is Simple!Build your own chips!

Chapter 133 My idea is very simple! Make your own chips!

"Hahaha, did you see it?"

"Old Wang, many countries are very interested in purchasing our filter membranes and soaking solutions!"

“Sewage treatment has always been a problem for these people!”

"But as Xiao Luo said, of course the price will be higher for foreigners!"

In Long Jianfei's office at the Magic City Military Industry, Wang Bozhao from the customs came to the door again.

The two of them were simply drinking tea and chatting.

But when they talked about the recent desalination of seawater, both of them became very emotional.

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

Without them, there would be absolutely no place today.

"Xiao Luo is great. When I found out about the filtration membrane factory, I directly made a statue of Xiao Luo. I think it was a bit excessive. But now looking at the reaction from the whole world, I think he deserves it!"

Wang Bozhao also said happily, and the two began to chat about the frequent happy events in the country recently.

But soon, Long Jianfei's phone rang.

When I saw it was Luo Feng calling.

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

"Hey, Xiao Luo."

"Hello, Mr. Long, I'm sorry to bother you again!" Luo Feng said with a smile when he saw that the call was answered in just 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?

"Mr. Long, I want to ask some questions!"

"you say!"

"That's it. If I want to invest in a wafer manufacturing plant, what are the procedures I need to go through? Is it complicated?"

Seeing Luo Feng ask this, Long Jianfei was frightened for a moment, "What? Xiao Luo? You want to build a wafer manufacturing plant?"

At this moment, his expression completely changed.

They all felt that they had heard wrongly.

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

"Yes!" Luo Feng nodded firmly.

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

"I know, a wafer is a monocrystalline silicon wafer, which is extracted from silica sand. It is a semiconductor material and a chip material!" Luo Feng filled in so much knowledge and answered in an instant.

Of course, Luo Feng knew that the other party did not want Luo Feng to popularize science.

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

Of course, the manufacturing specifications of wafers are also divided into 4 inches and 8 inches, but in recent years, larger specifications of 12 inches have been released.

The larger the wafer, the more ICs that can be produced on the same wafer, which can reduce more costs.

But the production technology is extremely strict.

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

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

Regeneration and building it yourself are two completely different things.

Wafer recycling is a process of reusing wafer scraps.

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 achieve 100% utilization. In fact, we only get 500 chips, which is not bad.

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

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

The wafer regeneration factory is to save production costs and 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, 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?"

When it came to this, the most critical issue, Long Jianfei started to look forward to it.

Although, now we also have a wafer manufacturing 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 in the Hai and Lin series very early.

But after being banned, top chip manufacturers such as Samsung will no longer OEM for Huawei, and our most advanced chip manufacturers are powerless.

Although Huawei itself also built its first wafer manufacturing plant, domestic 28nm wet equipment and domestic thin film deposition equipment were introduced into 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, to put it bluntly, compared with the top foreign nm technology, it is still far behind.

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

After all, the photolithography machine we developed ourselves can only successfully engrave lines with a line width of 9nm. For such top-notch chips, such a machine is powerless.

"I can't be sure yet, but at least it will be a 12-inch wafer production line, and 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 finished speaking.

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

"Huh? Okay then!"

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

Isn't this too anxious?

In addition to producing wafers, a fab 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 most advanced in the world.

We actually wanted to introduce such process equipment and technology at the earliest, but due to various reasons, it has never been possible.

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 Tianyuan Planet, this thing can’t even be called a chip.

Just like the battleships are the yachts of the rich 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 when Long Jianfei and the others came over, they called Zheng Zeyao along with them.

It was still the coffee shop that Luo Feng was familiar with, the Gushu Cafe.

When I meet Zheng Zeyao in my hometown of Luofeng, this is usually the place.

Of course, not only Zheng Zeyao and Long Jian flew over this time, but there was also a man wearing glasses, who was more elegant and had a bookish look on his face.

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

In fact, not many people know about Luo Feng's many contributions.

At the very least, this thirty-year-old doctor should not 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 am Ji Shunqing. I heard that you are planning to invest in a fab to manufacture chips, right?"

"Yes!"

"And you want to manufacture 5nm level ones?"

"Yes!" Luo Feng nodded without hesitation.

Ji Shunqing on the other side didn't know what to say. After smiling bitterly, he said, "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 was of high quality and naturally would not express his inner thoughts.

He just smiled slightly and said: "Mr. Luo, do you know that let alone 5nm-level chips, even if it is a 7nm-level chip, we can't get the corresponding equipment. Without the corresponding equipment, even if we have relevant knowledge, If you have talent, it will be like a tiger eating the sky, and you will have nothing to eat!"

"I can understand what you mean is that there is a lack of photolithography machines?"

In fact, if an expert speaks, it is generally easier to understand, but Luo Feng is a beginner who just checked the information all night, so naturally he does not understand many things very well.

So I asked.

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