From Almighty Scholar to Chief Scientist

Lin Xiao nodded and said, "Well, look, these red areas are areas with protruding particles, and these blue areas are areas that are recessed because of the lack of particles."

"Has your precision polishing equipment been upgraded?" he asked.

Luo Gangxian nodded, and said: "It has entered the research and development stage, and after that, it will be the work of replacing a servo motor. It is estimated that it will be done in August."

"Row."

Lin Xiao nodded, and then said: "Let's go and see your ion polishing machine."

"it is good."

Luo Gangxian nodded, and then took Lin Xiao to another laboratory.

"That's it."

"Ah."

Lin Xiao nodded, "Please give me a demonstration."

"it is good."

Luo Gangxian nodded, then waved to several other researchers in the room, and said, "Come and show Professor Lin our ion polishing technology."

These researchers have been looking at Lin Xiao curiously. They also knew that Lin Xiao was coming to help them research lens processing technology. They also wanted to know how Lin Xiao would help them solve this problem.

After hearing the director's words, they all responded: "Okay."

Then they came to their respective positions and began to operate.

The first is to take a lens that has only undergone other polishing steps.

The accuracy of this lens at this time is about 3nm-RMS.

The next ion beam polishing is the last step in lens processing.

After the lens is installed, the ion beam is emitted, and the ion beam is emitted to the surface of the mirror to directly flush the roughness of the surface.

This is a relatively lengthy step, and it takes a long time. After all, if the angle is not careful, a big hole may be punched out of the surface, so basically they have to recalibrate once they launch it. At this time, the experience of the polishing personnel is very important.

The better the experience, the higher the accuracy, and then with the calibration accuracy of the instrument itself, the higher the accuracy can be achieved.

In the Institute of Optoelectronics, the one with the highest experience in this area is naturally Luo Gangxian, so he directed these researchers to operate the ion polishing machine.

Related images also appeared on the computer screen next to it.

"Parameter input: ion beam voltage 800V, current 84mA, acceleration voltage minus 160V. Aiming point, 23, 12, 61."

"Parameter input..."

Every time Luo Gangxian said it, the researchers operated it once. After each processing, the color of a certain part or a large part of the screen image will change.

This is because after the ion beam bombardment, the above accuracy has changed.

Seeing these, Lin Xiao began to think in his mind.

In the past, the polishing accuracy of this ultra-smart optical lens, human experience is very important.

This is the case with the Zeiss company, they have generations of professionals.

However, their experience cannot leave the scope of scientific knowledge after all.

There must be a way to classify their experience into a formula.

Lin Xiao had thought about this question for a long time before, and now seeing their actual operation, coupled with the data of the lithography machine lens in his mind, his eyes suddenly lit up.

Ion beam bombardment, chemical bond breaking, material surface planarization...

The combination of these things is nothing more than a physical process, and as long as he can establish a mathematical model that completely explains this physical process system, according to this mathematical model, he can correct the process of each ion beam bombardment, and then directly replace the human body. Experience in achieving precision machining of the lens surface!

Thinking of this, he immediately spoke. "Academician Luo, it's alright."

Academician Luo was taken aback, and asked, "What's wrong?"

"I probably know how to solve it." Lin Xiao said: "Please send me your information, I need to study it after I go back."

Hearing what Lin Xiao said, Academician Luo suddenly showed surprise: "You have a solution?"

Lin Xiao smiled and said, "Probably, it's just a matter of a few mathematical formulas."

"How many mathematical formulas?"

"You will know later." Lin Xiao said, "Of course, to explain roughly, we only need to know the various properties of the lens material, as well as the data of the surface roughness distribution of the lens, and the data of the ion polishing machine, and then count them By establishing a mathematical model for several formulas, we can directly calculate our ion beam bombardment point from the precise numbers and coordinates."

"Then, as I told you before, you can knock the surface of the lens flat! It's like... whack-a-mole."

Hearing what Lin Xiao said, although Luo Gangxian still didn't know what he was going to do, at this moment, he could only say, "Then trouble Professor Lin."

Lin Xiao smiled and nodded.

Afterwards, he took these materials with him, left the Institute of Optoelectronics, returned to Shangjing, and began to delve into how to build this mathematical model.

In this way, time passed quickly.

……

In this way, half a month later.

"Huh, it's finally finished."

In Yanbeiyuan's house, Lin Xiao looked at the final result on the draft paper.

Half a month is neither long nor short for this problem.

The most important thing is that once he has figured out the key points of this problem, it is not very difficult, even though it involves ultra-precision fields, and there are as many as ten variables involved, but for Lin Xiao, It is not difficult to distinguish between these variables.

So to him, it's just a slightly more complex physics problem.

Although this problem is of great significance to ion beam polishing technology.

The next moment, Lin Xiao received a small surprise from the system.

"Congratulations to the host for establishing a general purpose for ion beam polishing, gaining 200 physics experience points, 100 mathematics experience points, 100 materials science experience points, and 6.5 truth points."

"Congratulations to the host, physics has been upgraded to level 5!"

The next moment, Lin Xiao felt his head go hot.

When the subject is upgraded to level 5, the degree of brain development is increased by 0.6%.

His brain development has officially reached 7.05%!

Chapter 241 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 is refracted by more than a dozen optical lenses, 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 for the light source is that the power is strong enough, otherwise, it is impossible for Huaguo to fail 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."
