From Almighty Scholar to Chief Scientist

"If that's the case, all the better."

Lin Xiao nodded.

"Well, that's it, I'll do it when I get back."

Ma Gaoliang said with a smile on his face.

This trip was not in vain. The importance of the silicon wafer production process is self-evident.

Even though he didn't know whether Lin Xiao could really solve this problem, but thinking back to the few words Lin Xiao wrote in that note, he believed Lin Xiao inexplicably in his heart.

But then, Lin Xiao said, "There is one more thing."

Ma Gaoliang was taken aback for a moment, and was even more pleasantly surprised: "What else is there?"

"More important than silicon wafers, servo motors."

"servo motor?!"

Ma Gaoliang was shocked again.

He is more familiar with servo motors. He was a worker in a machinery factory when he was young, and he has come to this point later. Servo motors are the core components of those machine tools. He knows very well that this How important things are to a country's industry.

"Say it!" His tone became serious again.

"For the research and development of servo motors, I need to set up my own team, as well as financial needs."

"This is absolutely no problem." Ma Gaoliang said: "Within 100 million, I will approve it directly for you. If it is less than [-] billion, I will hold a few meetings in our department and give you approval directly. If it is less than [-] billion, you fill out an application form. I will ask the National Council to approve it for you."

Lin Xiao didn't know whether to laugh or cry: "100 billion is not enough. If the servo motor is developed, it will be almost one billion."

Maybe it seems a little too much.

"You can raise the funds, I am very aware of the importance of servo motors to us."

Ma Gaoliang said very seriously.

Lin Xiao nodded slightly, and then said: "However, I still have a few requirements. The first point is that during the research process, everything needs to be based on my decision. The second point is that the partner cannot interfere with my research. , the third point, if I need some talent help, the government needs to help me."

Hearing these three conditions, Ma Gaoliang said: "Don't worry, there are no problems with these."

Lin Xiao nodded, and continued: "In addition, do you still remember what we said in Paris, if I return to China, do I have another request?"

"I remember, you said."

"In the future, I don't want any political interference."

Ma Gaoliang was taken aback for a moment, and then said: "This matter requires an order from the leader above. As you know, I can only manage our Science and Technology Bureau."

"Well, I know, then I will trouble you."

Lin Xiao nodded, picked up the Longjing tea next to him, took a sip, and said with emotion: "Good tea."

Ma Gaoliang also smiled, "The tea is delicious, and the dim sum here is also good."

"Ah."

……

a week later.

A brand-new state-owned enterprise was quietly established, directly established by the State-owned Assets Supervision and Administration Commission of the State Council, called Dingguang Technology Co., Ltd., with a registered capital of 10 billion yuan.

At the beginning of the company's establishment, there was only one manager, Lin Xiao.

Not long after, the company cooperated with Silicon Industry, a leading company in the domestic semiconductor material industry chain.

Then, the company began to recruit many talents in the domestic machinery industry.

Of course, no one has paid attention to these things for the time being.

But after a long time, when people look back on the past, they will know that today is the beginning of Huaguo's counterattack against foreign countries in the semiconductor industry.

It is also known as the first year of the rise of Huaguo Semiconductor.

Chapter 221 Investigates the silicon industry, systematically looking down on it

Magic City.

On the silicon industry, silicon wafer production plant.

Many people on the Internet think that chips are made of sand, first of all because chips are made of silicon wafers.

A major raw material for silicon wafers is sand, which can be directly mined from nature.

Very cheap.

Of course, after the processing, the price is not cheap at all.

For a 12-inch silicon wafer, the sand used may be filled in a bucket in a river dam. Although this also belongs to the ore and belongs to the country, it is obviously impossible for the country to care about you getting such a bucket, but it is processed into The price of silicon wafers that can be used as chips is directly as high as more than 600 yuan.

Of course, a 12-inch silicon wafer can be cut into four 500 yuan mobile phone SOC chips, and the price of a chip, taking Qualcomm’s Snapdragon price as an example, is basically one higher than a 12-inch silicon wafer. 200 yuan, and self-designed chips like Apple and Huawei, because they are for their own use, are completely cost price. Of course, when calculated on their products, the price represented by the soc chip is quite high.

Therefore, the more advanced the technology, the higher the profit that can be obtained.

This is why it is said that science and technology are primary productive forces.

"This year we expect to be able to produce 30 12-inch silicon wafers per month, which is 360 million for the whole year, but there is still a big gap with foreign countries, and the share is not much at all. The domestic market mainly imports foreign silicon wafers. round."

"But now the higher-ups have asked us to give you another one. The monthly output of this production line is [-] pieces, and the value is very high. Professor Lin, you can treat it well. If it doesn't work, you can call me and our company will pay to buy it again." return."

In the factory, Yu Jiancheng, the general manager of Shanghai Silicon Industry, said to the people standing beside him, with complaints and grievances in his tone.

And the person standing beside him was Lin Xiao.

After the establishment of Dingguang Technology Co., Ltd., under the leadership of the government, it reached a cooperation with the silicon industry.

Shanghai Silicon Industry took out a 12-inch wafer production line and Dingguang Technology Co., Ltd. jointly established a Dingguang Semiconductor Technology Co., Ltd., and this production line is mainly used for research by Lin Xiao, which is why Lin Xiao flew here from Shanghai. come here.

As for this General Manager Yu, the grievance is here. They went to the silicon industry as the first company to break the 12-inch zero production in Huaguo. It is losing money every year, but now it is directly allocated a production line worth tens of figures, which of course hurts.

Hearing Yu Jiancheng's words, Lin Xiao just smiled and was not angry. He just said, "You won't regret it in the future."

However, there was another person next to Lin Xiao who was dissatisfied with Yu Jiancheng's words, and said directly: "Professor Lin is a top scientist. If you don't believe Professor Lin, you should report it to the higher authorities. You don't want to pay anything. How can we make progress?"

This person is called Luo Ming, who is the general manager of Dingguang Technology Company, and is mainly responsible for the company's administrative management.

Lin Xiao is the chairman of the company, but it is obviously impossible for him to manage the company, so this Luo Ming is arranged to take charge of this job.

Of course, he also has another identity, that is, Lin Xiao's loyal fan.

It is of course dissatisfied to hear someone questioning one's idol.

But when Lin Xiao heard what Luo Ming said, he stretched out his hand to stop him dumbfounded: "Luo Ming, don't say that, we and Mr. Yu are also collaborators."

"It's okay, Mr. Luo is right, if you want to improve, you have to pay."

Yu Jiancheng waved his hand and said.

If their silicon wafer technology wants to improve, they must pay. This sentence is correct, and he also knows that cooperating with Lin Xiao is to optimize their production line to see if they can improve the yield rate and production speed.

However, he can gamble with the higher-ups, but he doesn’t like to gamble. Whether the company’s management is good or not has an impact on his performance. The most important thing is that although they are state-owned enterprises, there are some private shareholders in the company. Lin Xiao has the purpose of a production line.

Therefore, it is conceivable how distraught these private shareholders will be when they learn about this matter, and they will inevitably have to talk to him. Although he is not afraid, it will always be troublesome.

Of course, in fact, it is entirely possible to hire Lin Xiao as a research expert in the name of the above-mentioned silicon industry, but because Lin Xiao said that he did not want his research to be affected by the partner, the above directly "one size fits all" and directly cut this production line to After him, the new Dingguang Semiconductor Technology Company, he also has the dominant control.

This can be regarded as the excellence of Huaguo's system. You can do anything without considering the cost, and now there is no cost loss at all, it is almost just a left hand and a right hand.

Lin Xiao said: "Let's look at it from beginning to end, and tell me what our main problem is now."

"Okay." Yu Jiancheng nodded, and then led Lin Xiao to watch from their first step.

The first step is that trucks carrying sand drive into the factory to purify and refine the sand.

After this process, large pieces of pure polysilicon will be obtained. The purity of these polysilicons has basically reached 99.999999999%. After that, these polysilicons are melted, and then a rod is slowly pulled, which is a silicon rod, and the silicon rod is polished. , cut, and then polished, it becomes a silicon wafer.

This is the entire process flow, and the details determine the yield and production efficiency.

"We still have some problems in purification, and the other is the key polishing. Our ultra-precision polishing machines are all imported from Japan, and they are not the most advanced. They don't sell us the most advanced ones, so other people's polishing machines are better than others. We were three or four times faster."

"Basically these two key questions."

"Our problems mainly arise from..."

As Yu Jiancheng talked about their key issues, they also walked from the refining room to the smelting room. In the smelting workshop, silicon rods were produced, a large rod 1.5 meters long and 12 inches in size.

Since silicon is a semi-metal, its color is the same as that of metal, but it is a little grayer.

Until finally, they came to the final polisher.

"That's it, and it's our most critical problem. If we want to process silicon wafers to the precision we want, our polishing discs are not advanced enough, so we can only grind for a while, but we also have to worry about thermal expansion of the discs after grinding for a long time. make the accuracy worse."

Yu Jiancheng said.

Lin Xiao asked: "Is your polishing fluid traditional colloidal silica?"

"Yes."

Yu Jiancheng nodded.

"I see."

Lin Xiao said no more.

"Luo Ming, go back to the hotel."

"it is good."

Luo Ming responded immediately.

"Mr. Yu, before my research begins, you can still use this production line. The wafers produced will be handed over to your company for consignment sales. It's going to stop."

"Ok."

Yu Jiancheng nodded.

However, compared with a production line they lost directly, this output can only be comforted.

So he still said: "Professor Lin, I still hope that you can succeed. If you really succeed, even if we give you half of the production line, it will be no problem at all."

Lin Xiao smiled and said, "Just wait for the good news."

If he succeeds, the output will be directly increased by three or four times. Even if the production line is given to him by half, the output of the silicon industry can still be increased by two times.

Of course, everything depends on the final result.

After that, Lin Xiao and Luo Ming left the factory. Of course, they also took away a USB flash drive, which contained all the materials of the 12-inch silicon wafer production process of Shanghai Silicon Industry.

It is obviously not enough to just come here to have a look, and perfect information is also indispensable.

Back at the hotel, Lin Xiao said, "Then go back to Beijing tomorrow."

"Okay." Luo Ming nodded, and couldn't help asking: "Then, Professor Lin, do you have any thoughts on silicon wafers?"

Lin Xiao smiled and said: "This is a question that needs more thinking. If you ask now, I have nothing to answer you."

"Oh fine."

Luo Ming could only nod his head.

Lin Xiao waved his hand and returned to his room.

Recalling the information obtained today, the first is the purification problem.

If the polishing problem is a hardware problem, the purification problem is a software problem.

Everyone in the industry understands the truth that sand is silicon dioxide, let it react with carbon to get silicon ingots, and then react silicon ingots with hydrochloric acid to form high-purity trichlorosilane, and then electrify to precipitate polysilicon.

In this process, it is tested how the process avoids impurities.

For this point, Lin Xiao can play a good role in "bringing it". He already knows how a silicon wafer factory in Japan is purified by asking for it.

The Japanese silicon wafer factory is considered the best one, and their purification method is still very good.

Of course, copying is not in Lin Xiao's character. After so many months of thinking, he has come up with a better plan, and the purification speed can be increased by about 10%.

However, when it comes to polishing the hardware problem, the principle of "bringing it" cannot be used. After all, it is not a problem for a local Japanese company to buy a top-level polishing machine.

"So I have two directions now."

"First, develop a new grinding disc material, and second, develop a new polishing fluid."

The polishing accuracy is tested by the material problem, and at the same time, both the grinding disc and the polishing liquid are indispensable.

For example, the thermal expansion coefficient of the grinding disc material must be accurate. If the grinding disc material expands due to friction and heat, it will obviously affect the final polishing accuracy.
