From Almighty Scholar to Chief Scientist

Chapter 303 Prepare to Build Chips!
Dongguan City, the Songshan Lake headquarters of Warwick Corporation.

Ren Zhengfei, who was sitting in his office, was taken aback for a moment when he was asked whether he was interested in rebuilding the Kirin 9000, and then he couldn't help laughing.

This call is most likely to come to them to invest, and his number is a private number. It is estimated that he got his phone number from one of his friends and then called.

In the past, he must have asked this person to call their Warwick rotating director directly, and he didn't have the heart to take care of this kind of thing.

But this time it was different, the other party actually opened his mouth and said that he would rebuild the Kirin 9000, which still made him a little interested.

Are all the people who attract investment so vigorous now?

So he smiled and said, "Of course I'm interested, but I just don't know how you plan to help us recreate the Kirin 9000 chip?"

A voice came from the other end of the phone: "Hehe, in order to prevent Director Ren from thinking I'm joking, let me introduce myself first. I'm Lin Xiao, the chief designer of the X-ray project."

Ren Zhengfei was taken aback for a moment, Lin Xiao?

X-ray project?
He immediately stood up from his seat and said, "Master Lin? Is it really you?"

Lin Xiao smiled and said: "Of course it's me. If you need me to prove my identity, then I can ask our chief teacher Yang Kaiping to call you. Chief teacher Yang is right next to me now, and your phone number is also his. told me."

Ren Zhengfei thought for a moment, then said: "No need, I believe it."

There are not many people who know that he knows Yang Kaiping, since the other party can tell this matter, there is basically no need to question the other party's identity.

So, to put it this way...

Lin Xiao said to help them rebuild the Kirin 9000...

An excited expression suddenly appeared on his face, and he asked in a trembling voice: "So, the X-ray project...is it successful?!"

Lin Xiao smiled and said, "Well, I can't tell you about this for now, but if you believe me, then in the next few days, you or you can ask your Huawei executives to come to the Dingguang Research Institute. Let’s have a meeting, and then we’ll sign an agreement, by the way, remember to bring your Kirin 9000’s EDA file.”

Hearing Lin Xiao's answer, Ren Zhengfei also regained his composure.

I can't tell him the specific situation yet, so it's fine if he asks more after the meeting.

Of course, since Lin Xiao has called him specifically, there is a high probability that even if the X-ray project fails, it is not far from success.

So after thinking for a while, he said, "Okay, I see."

Afterwards, they discussed the time to meet, and decided that it would be three days later, Dingguang Research Institute.

Before hanging up the phone, Lin Xiao asked again with a smile: "Dong Ren, you should also know that even if the X-ray project is successful, it will be difficult to produce qualified chips without the corresponding technology. Just trust me ?"

Ren Zhengfei smiled and said: "Of course I know, but if the X-ray project is really successful, I will give you all the chip designs designed by Hayes, so that you can use them to study the production process, so what? As long as you succeed in the end, we, Huawei, will also benefit!"

"Ren Dong is indeed Ren Dong, so look forward to our meeting later."

"Haha, I can't wait any longer, so I'll see you in three days."

"Ah."

After hanging up the phone, Lin Xiao praised Ren Zhengfei's brilliance as an entrepreneur in his heart.

Obviously, if they can build a lithography machine, Warwick is probably the company that will benefit the most.

So for Ren Zhengfei, no matter how much money he invested, as long as he can succeed, he will be willing.

However, after he hung up the phone, people around him cast puzzled expressions at him.

"Master Lin, you also said that we don't have the corresponding production technology at all. How can we produce Huawei's chips?"

They originally thought that when Lin Xiao said that he would make chips for the National Day, he would just find a relatively simple chip and produce it, but Lin Xiao actually planned to directly produce Huawei's Kirin 9000?

How is this possible? !
Kirin 9000 is a 5nm process chip, how could they do it?

However, Lin Xiao just smiled lightly and said, "Who said we don't have the corresponding production technology?"

The eyes of the people present stared again.

"Master Lin...you don't want to say that you have even solved the problem of the production process?"

Yang Kaiping looked at Lin Xiao with an unbelievable expression.

Lin Xiao smiled mysteriously: "This matter will be kept secret for the time being."

Then he said: "Okay, now let's continue to try the complete workflow of our lithography machine."

Seeing Lin Xiao didn't say anything, everyone's hearts were itchy. Could it be that their chief teacher Lin really solved even the most critical production process?
But there is no way, you can't force Lin Xiao to say it, right?
So they could only complain in their hearts that Mr. Lin doesn't talk about martial arts, but likes to entertain people's appetites, and then honestly followed Lin Xiao's request, and started the second inspection process of the X-lithography machine.

If self-inspection is the key to the qualification of the lithography machine, then simulating the complete workflow of the lithography machine is the key to confirming that it can achieve the design purpose.

Especially in terms of production efficiency.

According to their calculations, the production efficiency of their X-lithography machine is 40% higher than Asmer's current most advanced EUV lithography machine!

So, now that the simulation test is started, can this kind of production efficiency be achieved?
Everyone present looked forward to it.

First, put silicon wafers into the lithography machine, and soon the staff pushed the trolley with ten silicon wafers to the silicon wafer entrance of the lithography machine, and then put these silicon wafers in one by one.

These silicon wafers are provided free of charge by the upper silicon industry and are specially used for testing them.

One year later, the silicon wafer production of the Shanghai Silicon Industry has reached the top three in the world, and the production line is being expanded. It plans to meet the top two Japanese manufacturers. Now it is considered rich and powerful, as I said before, X-ray plans to test silicon wafers, and they will provide as many pieces as they want, without any money.

For the Shanghai silicon industry, this silicon wafer is of course nothing, and they can be regarded as reciprocating.

Going back to the X-lithography machine, after the silicon wafer is put into the silicon wafer inlet of the lithography machine, there is a manipulator inside to lift the first silicon wafer up, of course, from the bottom, Doesn't hurt the smooth surface.

Then, the manipulator just held the silicon wafer, turned it around, and then just placed it on the first workbench, and then the workbench entered the predetermined position, and the pre-treatment of the silicon wafer began. scanning.

After scanning for about eight seconds, this workbench ended the scanning work, and quickly exchanged positions with another workbench, replacing the past, and came under the RDX pure silicon crystal lens.

Next, the most critical time came, that is, whether their X-rays could be engraved on this silicon wafer according to the established pattern, and covered 650 pieces!
That is equivalent to 650 chips!
A single chip is 80 square millimeters, and the 12-inch silicon wafer they used has an area of ​​about 70659 square millimeters. Excluding the loss of leftover materials, the best solution can just produce 650 chips!
Of course, the chip they plan to carve is very simple, or in other words, it cannot even be called a chip, because they just carve nanometer-level X patterns on it, and the light source they use has a wavelength of 3.56 nanometers, which means that , they can engrave an X with a line width of 3.56nm on it, and the line length is about 35nm, which is ten times the line width, which is equivalent to an X occupying an area of ​​about 600 square nanometers, and such a Come on, 80 billion Xs will be densely packed on an 1333 square millimeter chip!

This is the most sophisticated machine of mankind!
X-rays that cannot be seen by the naked eye are excited, pass through the RDX pure silicon crystal lens, and shine on the silicon wafer.

The X-ray photoresist that Huaguo had made long ago had already been applied on it, and then it began to react with X-rays.

The workbench was also sliding with the silicon wafer, and gradually, invisible patterns were formed on it.

After just ten seconds.

Lithography is complete.

The double workbench brought the silicon wafer to the exit, was picked up by the manipulator at the exit, and sent out of the exit.

When everyone saw the silicon wafer pushed out from the exit, they immediately surrounded it.

And Lin Xiao also walked up, and then picked up the silicon wafer.

Originally, the silicon wafer was gray and black, but now it is placed under the light, and it actually emits colorful brilliance!
This is precisely because more than 300 billion regular nano-scale X patterns are photo-etched on the surface, and the light shines on it, resulting in grating diffraction!

Seeing this gorgeous color, everyone present couldn't help showing intoxicated and obsessed eyes.

How beautiful!
This is the chip they made!

According to Samsung's water-filled process standard, they can all say that the process of this chip is 3.56nm!

Looking at this silicon wafer, Lin Xiao even wanted to reach out and touch it, but soon, he held back, and said, "Go and test the yield rate."

Immediately, someone next to him stepped forward to take over this fascinating silicon wafer and went to the testing equipment. Soon, he said: "The yield rate is 100%!"

There were happy smiles on the faces of the people present.

Of course, they were just happy. After all, their chip that only engraved X was not difficult at all, and it was just a 100% yield rate, which was really normal.

However, this also proves that their lithography machine can meet the established requirements when it works.

In addition, after such a short period of time, the photolithography of ten silicon wafers has already been completed, and the work efficiency has also reached the set goal!

That's what really makes them all happy.

Now they can completely say: Asmer's lithography machine is just a picture. If you really want to see the world's top lithography machine, it has to be their X-ray project!
Everyone's blood boiled with enthusiasm, and then they turned their eyes to Lin Xiao again.

"Master Lin, what shall we do next?"

Lin Xiao smiled slightly, walked to a lithography machine, then stretched out his hand, and gently stroked the X mark on it.

Then, he turned his head to look at them, and said with a smile, "In three days, we will sign an agreement with Huawei, and then, I will translate for you, what is a surprise!"

……

Three days later, in the conference room of Dingguang Research Institute, Lin Xiao had a "secret talk" with Ren Zhengfei, who came all the way from Huawei, and got the design drawing of Huawei Kirin 9000.

Then, he began to buy "furniture" for their clean room: oxidation furnace, deposition equipment, etching machine, encapsulation machine, ion implantation machine and so on.

These things are the indispensable equipment in the wafer manufacturing process.

The lithography machine is only the most sophisticated equipment among them, and it is also the only equipment that is stuck in Huaguo. As for other equipment, it can be bought in China.

Of course, Lin Xiao had placed an order for these things a long time ago, so these things can basically be shipped within a week.

While waiting for these things to be delivered, Lin Xiao finally revealed the answer to the mystery for them. He took out the 5nm process chip technology of the X-ray machine that he exchanged at the beginning, which shocked everyone in the X-ray project. days, and did not recover until a week later when all their equipment was in place.

Then, everyone was full of excitement and began to learn the process proposed by Lin Xiao. A process includes many links, mainly photolithography and etching.

A silicon wafer needs repeated photolithography and etching many times to produce the final product. After repeated photolithography and etching, the final complex integrated circuits can be formed.

And this process is the time to test the technology.

What makes TSMC better than Samsung is that the repetitive lithography and etching process they designed is better than Samsung!

As for how powerful the craftsmanship Lin Xiao gave, no one in the X-ray project knew, but it was better than nothing.

So, time passed quietly again.

And maybe it was an accident, or maybe it was intentional, the news of the "secret talk" between Lin Xiao and Huawei quietly leaked out.

Suddenly, the industry boiled.

All kinds of strange news spread throughout the industry, and the core of each news is——

Lin Xiao, the chief designer of the X-ray project, and Huawei, a company that is in urgent need of domestic lithography machines, what did they talk about?
