From Almighty Scholar to Chief Scientist

Chapter 242 August: Production Increased 2.6 Times

"Whoo~"

After calming down in his mind for a while, Lin Xiao felt his thinking regain clarity.

The increased brain development this time was less than one-tenth of the original level, and it was not a big burden on him. He was just a little dizzy, and after a while, the dizziness gradually subsided.

At this moment, he looked up at the surrounding environment again, and felt that everything around him seemed to be under his control, and he was even able to directly build the entire room into a 3D model, and then put it in his brain, And it's even possible to make changes directly to the model.

In addition, he even felt that he could now prime eight-digit numbers with ease.

At the same time, he felt that his understanding of physics seemed to be one step closer.

Originally, he got a [physics master aura] from the system because he proposed the multi-dimensional field theory before. This aura still has a high bonus to him, which is why he has the confidence to do it with the lithography machine.

And now his physics has been upgraded to level 5, which makes him more confident to shorten this time.

"Even... the EUV lithography machine is not a problem, it seems that the X-lithography machine can do it?"

This idea suddenly appeared in Lin Xiao's mind.

X-ray lithography machine refers to a lithography machine that uses X-rays as a light source.

X-rays have shorter wavelengths than extreme ultraviolet light, making it easier to produce advanced process chips.

And this lithography machine has an advantage, that is, its light source is directly irradiated on the bottom of the chip.

This exposure method is called direct writing.

In the light source of the EUV lithography machine, the EUV light source is refracted by more than a dozen lenses, and finally forms the chip on the chip by projection through the pattern on the mask plate.

That is to say, the X-lithography machine can be used without a photomask, and at the same time, it has very low requirements for the lens system, and only has a little requirement for the smoothness of the lens surface.

In addition, after the EUV light source has been refracted by the optical lens more than a dozen times, the energy of the original light source will be greatly weakened. The original 100% may only have less than 3% of the energy left in the end. This is why the EUV The requirement of the light source is that the power is strong enough, otherwise, it is impossible for Huaguo to achieve a breakthrough in the light source. After all, the method is known, and it is impossible to make it.

The X-lithography machine is different, because it is a direct writing type and does not need to be refracted by the lens, so there is no need to worry about the problem of insufficient power of the light source. Instead, the worry is that the exposure time is a little longer, which will affect the final effect. .

Of course, X-rays have many advantages, but they also have disadvantages.

That is, compared with EUV lithography machines, lithography efficiency is relatively low, and it is more difficult to achieve mass production. This is why X-lithography machines have not occupied the mainstream. Although they are still used now, they are not So people are concerned.

However, Lin Xiao naturally considered this issue, and he felt that the X-lithography machine could be developed because of the inspiration he had just flashed, which gave him a method to realize the mass production of X-lithography machines.

That is to use the diffraction effect.

X-rays are diffracted by crystals, and in general, crystal structures are determined substantially using X-ray diffraction.

But on the other hand, if you choose a suitable crystal material as the lens, and then use the diffraction effect to realize the scaling of X-rays, then you can achieve the production efficiency like EUV lithography machine, and add the powerful energy of X-rays to realize Faster production efficiency, very easy.

Of course, there is a difficult question, that is, what is the suitable crystal. In addition, the control of X-rays by using the diffraction effect requires a huge amount of data to be processed.

So until now, although this kind of diffraction effect has been used to realize chip manufacturing, it is basically limited to some special graphics, and there are very few application cases.

For Lin Xiao, he just thought about it this way.

Although he is still a little bit sure now, if he tells the outside world that he wants to build an X-ray machine, I am afraid that Huaxin League will have to withdraw more than half of it the next day.

Without thinking too much, he turned his gaze back to the mathematical model in front of him.

Now that he has upgraded, looking back at this model again, he suddenly feels that this model still seems to be lacking?
"Well... this model seems to be able to be further optimized."

After a moment of thinking, he found a point that could be optimized.

"Well, there is still one thing that can be optimized for the ion polisher calibration system."

The calibration system of the ion polisher is affected by its own accuracy. Of course, considering the influence of the internal magnetic field, the trajectory of the ion beam will be disturbed by the magnetic field, just like the particle accelerator will also be disturbed by the magnetic field.

Therefore, if the magnetic field interference error is more accurately corrected in the calibration system, or the difference between the magnetic field error and the ion polisher's own precision error is used, more accurate polishing can also be achieved.

Thinking of this, Lin Xiao immediately started to calculate, and this step is actually very easy, that is the root investigation method.

Ion beam polishing machine, jet plasma, influence of magnetic field error... Can these things be solved by root investigation?

Of course, due to some differences in structure and function, it is also necessary to make a simple modification to the root search method.

And this step is not difficult.

After about half an hour, he completed the optimization of this model.

After solving this problem, the corner of Lin Xiao's mouth curled up.

"I'm really good."

After touching his face, Lin Xiao stretched out his hand to rub Mimi who was sleeping next to him, and asked with a smile, "Mimi, are you right?"

"Meow~"

Mimi's curled up body didn't move, she just called out, probably as a response.

Lin Xiao smiled, masturbated again, and then contacted Luo Gangxian to tell him the news.

Naturally, I was very pleasantly surprised. I didn't expect Lin Xiao to solve this problem so quickly.

After getting Lin Xiao's mathematical model, he was even more amazed. This mathematical model is full of various variables, but after a glance, it makes people feel the existence of a kind of mathematical beauty.

Soon, Luo Gangxian sorted out all the mathematical models, and immediately saw the key points of the model: "Professor Lin, is this model... a program?"

"Yes." Lin Xiao said: "Write it as a program and put it into the system of the ion polishing machine, it can effectively improve the precision of polishing."

"In addition, the most important thing is that it can replace human experience, which means that even if we don't have a top polishing master like Zeiss, we can still polish top optical lenses!"

Hearing this, Luo Gangxian was even more shocked: "Can it replace the operator's experience? Mr. Lin, are you sure?"

Lin Xiao smiled: "I'm sure, you'll know after a try."

"Okay, I'll give it a try right away, thank you anyway."

"It's nothing, this is exactly the purpose of my proposal to establish Huaxin League."

Lin Xiao said.

"Yes."

Luo Gangxian replied, feeling Lin Xiao's spirit again in his heart, who else in the world has both such ability and such ambition?
After hanging up the phone, Luo Gangxian stopped thinking about it, and the best way to repay Lin Xiao now is to tell him that he succeeded.

Then, he immediately returned to the laboratory, called all the relevant researchers together, and held a meeting.

"Everyone, some time ago, Professor Lin Xiao came to visit our ultra-precision optical lens polishing technology. According to the agreement of Huaxin League, he brought us an optimized plan. You can take a look now."

With that said, Luo Gangxian also showed the mathematical model to the people present.

The people present looked at this mathematical model, and they were as amazed as Luo Gangxian. This was actually created by Lin Xiao within half a month. Looking at the several mathematical formulas in this model, although they are not clear about these formulas What does it represent, but just at first glance, they will feel unclear.

"Okay, now let's talk about the model."

After getting this mathematical model, they naturally need to go through research and discussion to understand it.

If you can't understand it before using it, then they should all go home and farm.

Then, they started discussing, discussing every detail in this model.

The people present are all experts in this field, and they have done a lot of research on ion polishing, and the more they interpret this mathematical model, the more they can feel Lin Xiao's ability.

The more variables there are, the more difficult it is to integrate them. If they were the ones who came to make this model, it would probably be enough for them to organize a lot of people, and then apply for a million-dollar funding to study it for a year or so.

In this way, after several days of discussion, coupled with the communication with Lin Xiao, they finally sorted out the model.

They then used this model to optimize their ion beam polishing system.

System optimization is a relatively long process, and they need to constantly check the correctness of the program and determine the BUG.

So it will take a long time again. Of course, these times are not a problem at all compared to the time when no success is seen.

……

After finishing the lens polishing technology, Lin Xiao started the research on the double workbench.

The double workbench is a component that can increase the production efficiency of the lithography machine. One workbench scans the silicon wafer, and one workbench performs lithography.

Huaguo has achieved an important breakthrough in the dual-table technology. Using the magnetic levitation micro-motion technology, it has achieved a motion precision better than 2nm and improved the resolution of the dual-table. Mayer is the second country that has mastered the technology of dual-table of lithography machine.

However, there are still many problems in the practical application of this technology. This breakthrough dual workbench cannot be directly used on EUV lithography machines.

Of course, there are problems in comparison, at least now there are entities, so it is not difficult for Lin Xiao to achieve optimization, but apart from optimization, the most critical point is the upper limit of the accuracy of the basic instrument.

Lin Xiao's optimization can only do his best to make the utilization of their instruments reach the upper limit, but he cannot raise the upper limit of the accuracy of these instruments. The higher the upper limit of the accuracy of the instrument, the only thing is that the basic attributes of the instrument can be improved.

It is equivalent to that he is a top game master, manipulating a character with two gods costumes to fight a rookie with four gods costumes, he can still beat this rookie with his operation, but if the opponent is a rookie with six gods costumes, he can kill him with one blow. If he was killed, no matter how good he was, it would be impossible for him to evade other people's normal attacks.

Of course, they are not without the opportunity to increase the upper limit of this instrument, that is, the encoder technology.

Lin Xiao's research on the eight-point structure encoder was for the research and development of various aspects of the lithography machine. Now that they have improved the accuracy of the encoder, these accuracies can also be improved, including the previous ion beam polishing technology, As long as they improve the accuracy of the encoder, none of these issues will be a problem.

Now, the research on eight-point structure encoders across the country has entered an upsurge. After all, anyone with a discerning eye can see that as long as this new encoder is used to develop a more accurate motor, it will be very difficult for Huahua, which has always been short of ultra-precision instruments. As far as China is concerned, it will be able to make a lot of money by then.

Of course, due to Lin Xiao's restrictions on those foreign companies, the research in this area is only Chinese companies, and more state-owned research institutions. Such a craze, those foreign companies can only watch, and have no choice but to be jealous.

But now, there are actually many encoders that use the eight-point structure on the market. These encoders are relatively cheaper in price because of their low manufacturing cost and do not require such advanced sensors. Class encoders have also begun to occupy various related markets, such as the elevator market, and some low- and medium-precision servo motor markets.

As for the high-precision servo motor, it is still under study, but it is just considering how to better embed the octagonal structure into the original structure, which is not difficult.

Servo motor encoders like dual-tables are also under active development.

As long as these encoders are developed, all problems will be solved.

……

The time came to August.

August is a good month. This month, the first phase of Lin Xiao's research institute was finally completed.

The research institute is called Dingguang Research Institute, which is under the name of Dingguang Technology Company, a national asset, and is directly under the jurisdiction of the leader. The director is Lin Xiao.

Therefore, its control completely belongs to Lin Xiao.

The first phase of the project is mainly for the physics laboratory and the chemical laboratory. After several months of purchasing, the relevant instruments have basically arrived. Except for some important precision instruments, it will take a certain amount of time, such as scanning electron microscopes, etc. Because the instrument is more precise and expensive, it will take a while for the supplier to manufacture it.

Of course, after the establishment of the research institute, it is natural to recruit troops.

The postdoctoral fellows in material science that Lin Xiao dug from Peking University before joined the institute without any accident. In addition, there were some people who came here especially, including some famous people in the industry.

"Shen Nan? You were the general manager of Anji Technology before? Why do you want to come to our research institute?"

In a conference room in the research institute, Lin Xiao was interviewing his own management staff, and now he was interviewing the deputy administrative director of the Chemistry Department, who was in charge of administrative affairs.

The current interviewer is the former general manager of Anji Technology, a leading polishing fluid company in China.

Shen Nan said: "My original company is a bit content with the status quo, so I want to join Professor Lin's team."

"I graduated from Xigong University with a Ph.D. in materials, and I also have a master's degree in business administration from Xi'an Jiaotong University. I have certain experience in experimental research and administrative affairs management."

"Anji Company's current research and development process of cerium oxide CMP polishing fluid is led by me."

"In addition, I also have some experience with other photolithography materials, including photoresist, etc., and I have also done research before."

Shen Nan introduced his own advantages, and Lin Xiao also nodded. Regardless of his education background, his work experience is considered excellent among all applicants.

"However, our salary is not higher than yours as the general manager."

At this time Lin Xiao said.

Shen Nan smiled and said: "I can come here, of course I have not considered the issue of salary."

Moreover, although he left Anji Technology, he still had shares of Anji Technology in his hands, so after leaving Anji Technology, he sold these shares, and now he is worth hundreds of millions. When he came to Dingguang Research Institute, he In other words, it is only for the needs of self-realization.

Of course, he didn't say anything about it, and there was no need to say it after all.

But Lin Xiao nodded and said, "Okay, Mr. Shen, that's it, just wait for the news later."

"Ok."

Shen Nan nodded, then got up and left.

Then Lin Xiao continued to interview the next person.

After several days of interview work, the first batch of recruitment work was completed, including Shen Nan who also successfully served as the deputy administrative director of the Chemical Department.

Now that he has his own research institute and people, Lin Xiao doesn't need to continue to use other people's laboratories if he wants to conduct experiments in the future.

For him, it was a lot easier.

But obviously, in August, it wasn't just the first phase of the institute's completion of such a thing.

The first batch of production lines for polishing fluids and polishing discs has been officially set up, and they have started to produce their brand new polishing discs and polishing fluids at full speed.

Soon, the first batch of goods was officially delivered, and the buyer was Shanghai Silicon Industry.

The Silicon Industry has already upgraded their existing production lines, and now they are waiting for these materials to arrive.

The first batch of materials can support their two-month production volume, and with this batch of materials, the production speed of silicon wafers in the upper silicon industry will be directly full.

"Mr. Yu! We can now receive orders for 50 more pieces per month! The output has increased to 2.6 times the original! And our yield rate has also been greatly improved!"

After careful calculation by the technicians, Yu Jiancheng's secretary told him the amazing news.

Hearing this news, Yu Jiancheng's eyes widened.

Adding up all their previous production lines, they could only produce 30 pieces per month, or about 360 million pieces a year.

As a result, they are actually able to receive an additional 50 orders per month?

This is also the reason why their expanded production line has not been completed. After all, the time required to build a new production line is different from an upgraded production line. If all the twenty production lines they are still expanding are completed, then they will not be able to produce directly every month. More than 100 million pieces?
That's more than 1000 million pieces a year!

Such an output is completely a first-class manufacturer among the world's silicon wafer production plants!

As long as they continue to expand more production lines, it is not impossible to directly eat 20.00% or [-]% of the world's market in the future.

Of course, what you need to know is that the world needs hundreds of millions of 12-inch silicon wafers every year. Even if the annual output is more than 1000 million, it is not high for the total demand, but at least he sees hope.

Thinking of this, Yu Jiancheng was so excited that he probably didn't even know how to describe it.

He was also extremely fortunate, thanks to the fact that they were the first batch to cooperate with Lin Xiao, and they were able to enjoy the two batches of new polishing materials first, otherwise, it might not be their turn to do this kind of thing!

He couldn't help clasping his hands together, and bowed to the north.

Professor Lin, awesome!
Then, he immediately said: "Announce this news to me immediately, and occupy the market as soon as possible. Silicon wafers have been in short supply in recent years. This is our opportunity!"

"By the way, just hold a press conference directly! Find more media, both domestic and foreign!"

"Yes!"

The secretary also responded excitedly, and went to do it immediately.

A few days later, the news spread, and foreign silicon wafer manufacturers were shocked.

Huaguo manufacturers, after a technological breakthrough, actually doubled their monthly output?
This simply made them all feel incredible!
