From all-round academic master to chief scientist - Chapter 259 The unsatisfactory academic world

At three o’clock, the meeting started on time.

There are nine people in their team, including Lin Xiao, four researchers, and the rest are mainly assistant researchers and intern researchers.

Compared with some other materials research teams, the number of people is obviously still too low.

Of course, for a research team, quantity is not important, quality is more important. Sometimes a genius idea can push the research progress to the end.

And the people in their group are of course a quality-oriented group.

Needless to say, Lin Xiao is a cheater. Zhao Sheng, who Lin Xiao called before, is not only a brain in computational materials science, but also a master in experiments and is very famous in China.

As for the other two researchers, one of them is also a master in computational materials, while the other researcher is a master in experiments.

If it weren’t for these three experts, it would have taken some time for Lin Xiao to determine the crystal structure so quickly.

In the conference room, Lin Xiao re-used the software on the big screen to show the diffraction image of X-rays produced by this silicon crystal under the irradiation of X-rays. The light source of the X-rays is a plane wave, which passes through the lens. After that, a square projection is finally formed on another plane. This is the role of this lens. It can limit the X-ray irradiation range to a square.

This is very effective for the production speed of chips. After all, current chips are all square. This is also to improve the utilization rate of wafers. Due to the process, wafers can only be made into circles. In order to better Using each piece of this circle, the chip becomes a square.

The X-ray irradiation range becomes a square, which is more convenient when processing silicon wafers. By then, relying on the strong efficiency of X-rays, the speed of processing chips will also be greatly improved. Asmail’s EUV The photolithography machine can process two hundred silicon wafers per hour, and almost three polysilicon wafers per minute.

If calculated based on the area of ​​Apple’s A15 chip, and if the loss of silicon wafer scraps is ignored, one silicon wafer can produce 650 A15 chips, and 130,000 chips can be produced in one hour, which is more than three million in one day.

But if an X-ray source is used, the number of silicon wafers processed per hour can easily reach more than 200, and maybe 4.

This is the advantage of their X-ray source once it is used in mass production.

Then, Lin Xiao adjusted the parameters so that the crystal lens above began to rotate, and the X-rays began to change accordingly. The irradiation range began to change. At 57.5 degrees, the irradiation range was the same size as the light source. When it exceeded 57.5 degrees, , the irradiation range begins to converge and condense until the incident angle changes to a vertical 90 degrees and becomes a point.

Of course, this is what can be seen in computer simulations. In fact, X-rays are invisible light.

At this time, the X-ray condensed into a point is so powerful that if it is illuminated, it can directly produce a random cancer BUFF, which is probably similar to the cancer case caused by a nuclear power plant explosion in the island country next door.

“marvelous!”

Looking at the results above, everyone present cheered.

They did not doubt the authenticity of this image, because when Lin Xiao took out his wave coherence superposition equations, they did not doubt that they would fail.

When Lin Xiao told them the purpose of the experiment, they all felt like they had fallen into a pit. Using diffraction to control the amplification and reduction of X-rays?

Even if Lin Xiao said that he wanted to prove the existence and smoothness of the solution to the NS equation, they all believed it, but if you want to do this, how much data do you have to process?

However, until Lin Xiao took out what he named Lin’s wave coherence superposition equations and introduced it to them, they completely believed it – of course, because of the confidentiality of the wave coherence superposition equations , before Lin Xiao told them the equation, they had already signed a confidentiality agreement. As for background checks, they had already gone through stricter background checks before joining Dingguang Research Institute, so there was no need to worry about leaks.

In short, the crystal structure they designed has been successful.

Thinking back on the hardships during the process…well, well, it doesn’t seem like it was anything difficult.

Such a major breakthrough was achieved in one and a half months, which would have been impossible in any of the previous projects they participated in.

And this month, they have seen how strong Lin Xiao’s mathematical ability is. To build this structure, mathematical calculations are the most troublesome. If it weren’t for Lin Xiao’s powerful computing power and contribution to the construction of mathematical models, just with If a few of them come, I am afraid that even with Lin Xiao’s formula, it will take them who knows how long to come up with this structure.

Looking at Lin Xiao’s young face, they couldn’t help but sigh. It’s no wonder that he has become the director of such a key research institute at such a young age. He is worthy of the country’s special investment in him.

However, Lin Xiao didn’t think so much. After the demonstration, he looked at the people present and said, “Okay, let’s think about it now, how should we build it.”

After hearing Lin Xiao’s words, everyone present immediately began to think.

Ordinary lenses do not need to consider production issues, only polishing issues, but the lens they need requires X-rays to penetrate directly.

Moreover, the energy of X-rays is very strong, and the temperature of the object after irradiation will also increase. This requires the thermal expansion coefficient of the material they designed to be low enough. Of course, they have already considered this. According to simulation calculations, their The thermal expansion coefficient of the material is very low, so there will be no problem even if it is exposed to X-rays for a long time.

However, these require a more perfect production process. If they are not produced, it will be useless.

Of course, calculated this way, the production cost of their lens will be much higher than that of the lens of the EUV lithography machine. Of course, they only need one piece, while the EUV lithography machine requires more than a dozen. So no matter how you calculate it, it is more convenient for them.

Everyone was thinking, and Lin Xiao was also thinking.

How to produce a new material from scratch is undoubtedly very complicated, and although they now know the crystal structure, at least it is not completely ‘nothing’, it is still very difficult to actually create it. , which requires reference to various materials and chemistry knowledge, as well as condensed matter knowledge.

No matter what, as long as it is science fiction materials that do not involve the use of weak or strong interactions, the materials of humans on earth are still limited to electromagnetic interaction materials.

Therefore, it is the relationship between electrons.

Thinking of this, Lin Xiao suddenly remembered something.

“By the way, have there been any papers on Lin’s silicon bonding mechanism? Or can’t they be found?”

“Lin’s silicon bonding mechanism? As for this…it doesn’t seem to exist.” Zhao Sheng said.

“There’s none?”

Lin Xiao frowned slightly.

Lin’s silicon bonding mechanism is the bonding mechanism of silicon found based on his rules and research methods of Lin’s titanium bonding mechanism.

This is also the default thing in the academic world. In terms of naming, any bonding mechanism found according to his method must be named Lin’s bonding mechanism.

Although he did not study this thing personally, as the first person, he can naturally enjoy this kind of treatment, and this is also convenient for the academic community to call it. Otherwise, in the future, a Zhang three-carbon bonding mechanism will be a Li The four-silicon bonding mechanism is obviously challenging the memory of scientists.

However, not every element has found this bonding mechanism, but only some elements have. For example, the bonding mechanism of silicon has not yet been found.

This is not a certain problem with Lin’s bonding mechanism, but it may be that there is still room for exploration in Lin’s bonding mechanism. This also makes the academic community very excited. Maybe, if Lin’s bonding mechanism can be discovered, Where the mechanism has not yet explored, will there be a new revolution in the world of chemistry?

After all, this is about exploring the principles of the formation of various chemical bonds and explaining the process. In this way, people can understand the reasons for the formation of various substances more essentially, thus laying the foundation for controlling the formation of chemical bonds between elements.

Of course, there are also some people who think that this is the limit of Lin’s bonding mechanism. The process of chemical bond formation of all elements cannot be fully understood. It can only be said to explain a small number of elements, while other elements need to be counted according to another method. And this statement makes people think that these elements that can follow Lin’s bonding mechanism all have certain same properties, while other elements that do not follow Lin’s bonding mechanism have other properties. It’s like Fermi-Dirac statistics and Bose-Einstein statistics in quantum mechanics.

However, Lin Xiao has no time to care about these things now. He just feels a little regretful that the bonding mechanism of silicon has not yet appeared.

He deduced the bonding mechanism of titanium from the structure and various data of TA1000, so he knows the potential of this mechanism better than anyone in the world. By using the silicon bonding mechanism, he has every chance to design Produce the silicon material he needs now.

“Is it possible that I have to go back to my old job?”

He couldn’t help but think about it.

Do you want to figure out the silicon bonding mechanism?

This made him couldn’t help but complain in his heart.

Mmp, people in the current chemistry and materials science circles are too crotch-stretching, right?

He handed over the methods and rules to them, but it has been more than two years, and they haven’t even figured out the bonding mechanism of silicon.

It’s really a bit too incompetent, isn’t it?

In the end, he had to write the manuscript himself, which was really disappointing.

Sighing, he then said: “Then you continue to think about it. I’m going to look at the bonding mechanisms of several other elements. I’ll see if I can study the bonding mechanism of silicon.”

Hearing what Lin Xiao said, everyone present brightened up, but after a while they became confused again.

Another researcher named Li Bin asked: “Director, do you think silicon will follow your bonding mechanism?”

Lin Xiao spread his hands and said, “Even if I don’t follow it, it doesn’t stop me from giving it a try, right? It’s all about research.”

It’s all the same to him anyway.

Hearing what Lin Xiao said, the others no longer had any doubts.

Indeed, it is all about research anyway, so which direction is it not?

And if Lin Xiao can really study the bonding mechanism of silicon, it may indeed be of great help to them.

So now it seems that they have to divide their forces into two groups to try to make a breakthrough in preparing this new silicon crystal.

Lin Xiao announced: “That’s it for today’s meeting. There will be results in a week. Let’s continue the regular meeting.”

“good.”

Others nodded, and then they left the conference room without saying any more.
