Chapter 133 My idea is very simple! Make your own chips!
“Hahaha, did you see it?”
“Old Wang, many countries are very interested in buying our filter membranes and soaking solutions!”
< br>“Sewage treatment has always been a problem for these people!”
“But as Xiao Luo said, foreigners will of course have higher prices!”
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 excited.
And they know that all of this stems from Luo Feng and the teams 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 too much. But now looking at the reaction from the whole world, I think he deserves it!"
Wang Bozhao Said with relief, 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.
"Hello, Xiao Luo."
"Hello, Mr. Long, I'm sorry to bother you again!" Luo Feng said with a smile when he saw that he answered the call in just a few seconds.
"Haha, what are you talking about? Why are you disturbing me? All the calls you make to me are just to disturb me. I hope such interruptions come to disturb me every day." Seeing this, Long Jianfei was in a good mood He naturally laughed.
Every time Luo Feng took the initiative to contact him, good things happened.
Who wouldn’t like this kind of interruption?
"Mr. Long, I would like to ask some questions!"
"Say!"
"That's it. If I want to invest in a wafer manufacturing plant, what are the procedures I need to go through? It's complicated. Not complicated?"
Seeing Luo Feng ask, Long Jianfei was stunned for a moment, "What? Xiao Luo? You want to build a wafer manufacturing plant?"
At this moment His expression changed completely.
They all felt that they had heard wrongly.
"Sorry, Xiao Luo, I lost my composure!" But Long Jianfei immediately thought that it was not someone else who said this, but Luo Feng. Then he relaxed a little and asked, "Xiao Luo, you 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?"
"Yes, wafers are single-crystal silicon wafers, which are extracted from silica sand, semiconductor materials, and chip materials!" Luo Feng E had gained 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 to 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 coughed immediately when he heard this, Interrupted: "Mr. Long, are you serious? What I want to do is not a wafer regeneration factory, but a direct manufacturing. It is a first-hand product!"
Recycling and building it yourself are not the same thing. It's just two different things.
Wafer recycling is a process of reusing wafer scraps.
For example, the area of a 12-inch wafer is about 70,000 square millimeters. Taking the 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 achieve 100% utilization. In fact, we only get 500 chips, which is not bad.
So, at the same time, about 10% to 20% of wafer scraps will remain.
As Long Jianfei said just now, 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, of course I will be very happy, but the investment in this thing is not small. What's more important is that we need people with this expertise," Long Jianfei said, curiously asking, "By the way, Xiao Luo, how much nanometer 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 for the Hai and Lin series chips 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 also built its first wafer manufacturing plant, domestic 28nm wet-process equipment and domestic thin-film deposition equipment were introduced into the 14nm production line.
There are also mass production of domestic 28nm chips this year, mass production of 14nm chips next year, and the "dual-core superposition" patent disclosed by Huawei. Two 14nm chips are superimposed together, and the performance is comparable to 7nm chips, etc. information.
Despite this, 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 disadvantage 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's a 12-inch wafer production line, and a 5nm chip process!"
Luo Feng's words directly shocked Wang Bozhao, who was drinking tea on the side. , were all shocked, "Xiao Luo, are you telling the truth?"
"Yes, Xiao Luo, this seems impossible, 5nm process?" Long Jianfei was also surprised. Authentic, his face was pale.
"Of course! What I said is true!"
Luo Feng finished his words.
The two people 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!"
" Ah? Okay then!"
Luo Feng hung up the phone and was a little speechless about this Long Jianfei.
Isn’t this too anxious?
A fab, in addition to producing wafers, can also directly manufacture chips.
However, there is a big gap in the level of chips that can be produced using different equipment and manufacturing processes.
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 getting to a more advanced level, Luo Feng naturally took it out without any intention. This thing cannot be achieved overnight, it must be done slowly.
Otherwise, on Tianyuan Planet, this thing can’t even be called a chip
For example, battleships are all wealthy yachts over there
In the afternoon of that day, Luo Feng received a call from Zheng Zeyao. Zheng Zeyao was also on vacation in Hangzhou these days.
Probably when Long Jianfei and the others came over, they called Zheng Zeyao along with them.
It is still the coffee shop that Luo Feng is more familiar with, the Gushu Cafe.
When I meet Zheng Zeyao in my hometown of Luofeng, I usually meet at this 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.
"Xiao Luo! Let me introduce it to you!"
Seeing Luo Feng and Zheng Zeyao sitting across from each other, Long Jianfei spread his hands towards the young doctor beside him, "This is our Godson expert, his name is Ji Shunqing."
As he said that, Long Jianfei Looking at Ji Shunqing, "Shunqing, this is Mr. Luo! I told you the situation, you can introduce yourself to Mr. Luo Let's go!"
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 wafer factory to manufacture chips, right? "
"Yes!"
"And you want to make it at the 5nm level?"
"Yes!" Luo Feng nodded without hesitation.
The other person, Ji Shunqing, didn’t know what to say. After smiling bitterly, he said, "Mr. Luo, do you really know about this industry?"
"I did check some 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 and naturally will 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. There is no corresponding equipment. , even if you have relevant knowledge and talents, you will still be able to eat everything you want.”
"What you mean, I can understand, is that there is a lack of photolithography machines?"
In fact, if you speak from an expert, it is generally easier to understand, but Luo Feng is a beginner who just checked the information all night. Naturally, I don’t 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.
