Chapter 213 Peaceful Evolution
Now some caring people can restrain their greed.

That's because the power of the country is protecting Xingchen Company, if...

Can't resist it?

"I still don't want to see the bloodshed happen."

Zhang Xingchen shook his head and said.

"But Lao Zhang, have you ever thought that as we master more and more technologies, sooner or later our power will surpass this planet. What will we do then?"

"Will they allow us to exist?"

"Then let's evolve peacefully. We are all people on the same planet, and we have to deal with aliens in unison."

Zhang Xingchen said with a smile.

"The technology we have now is not enough to surpass all the countries on this planet, let's develop insignificantly."

"Okay, let's make a lithography machine first."

Zhang Xingchen said with a smile.

It didn't take long for Xiaobai to manufacture a 45nm lithography machine under the command and leadership of his robots.

"Look at Zhang, this lithography machine must satisfy you, it can only produce 45nm chips."

Xiaobai said with some pride: "In order to get stuck in 45 nanometers, I spent a lot of thought."

"Because it is a low-level lithography machine of 45 nanometers, I can only use DUV light, that is, deep ultraviolet light."

"This kind of light is invisible light, and its specific name is ArF excimer laser, which is its scientific name."

"The wavelength of the ArF excimer laser is 183 nanometers long. In the DUV lithography machine, it can be divided into two types according to the working method."

These two types are dry separation type and liquid immersion type. This time to manufacture DUV lithography machines, Xingchen chose the liquid immersion type.

The theoretical upper limit of the liquid invasion method is that seven-nanometer chips can be produced.

It's scary to think about it. The DUV lithography machine can actually manufacture seven-nanometer chips. The first feeling is that it is impossible.

But no one will do this, the way liquid invasion works is to use multiple exposures to improve accuracy.

Although the precision has increased, the difficulty has been greatly improved.

With each exposure, the precision increases, but the difficulty also increases naturally.

With the accumulation of layers like this, the difficulty increases so much that the yield rate of the manufactured chips is very low.

It is a loss-making business at all, and it is only suitable for production regardless of cost, and it cannot be profitable at all.

Not only can't make a profit, but it also loses a lot of money.

According to the actual situation, in fact, if you want to manufacture chips below ten nanometers, the best choice is to use EUV light, that is, extreme violet light.

It's just that the lithography machine that uses extreme violet light is an EUV lithography machine. If Xingchen Company comes out with an EUV lithography machine now, it will be really scary.

Continue... After the DUV light is emitted by the laser transmitter, there will be a certain deviation in the direction. If you want to reverse this deviation at this time, you need a beam corrector to correct it.

Under normal circumstances, three beam correctors are needed to correct it. Here Xiaobai uses four beam correctors to improve the correction degree.

In this way, the correction rate is higher and the effect is better.

Light is also a quantity. After the beam is corrected, an energy controller is needed to control the energy of the beam.

Set the energy of the beam according to our actual needs.

If we need more energy, then we should increase the energy; if we need less energy, then we should adjust it lower.

This is completely under our control.

The next step is the beam shaping device, which can be used to control the beam to form the shape you want.

After adjusting the shape and energy of the beam, it will be checked by an energy detector.

See if the light beam at this time can meet our requirements.

Typically, the shape of the beam is adjusted to a cylindrical shape.

A beam of light is first shone onto a mask placed on a photomask stage.

The light beam is irradiated on the convex lens through the slit on the mask, and the convex lens refracts the light beam to the silicon wafer already placed on the exposure table through refraction.

"This is basically the working principle of this lithography machine." Xiaobai said.

After hearing this, Zhang Xingchen nodded: "In fact, the work is almost the same, it still depends on the precision."

"Let's announce the news to the outside world." Zhang Xingchen said to Xiaobai.

Now we have been able to manufacture 90nm lithography machines. In fact, there is not much difference between 45nm and 90nm...

At least Zhang Xingchen thinks that there is not much difference. As for the fact that Zhang Xingchen thinks it is true, the benevolent sees benevolence, and the wise sees wisdom.

As for whether someone will buy it back for research, Zhang Xingchen actually doesn't care. If someone in our country can study the 45nm lithography machine of Xingchen Company and finally copy it, that would be a good thing.

Zhang Xingchen is not afraid that you can research it, but he is afraid that you can't.

Because this is a good thing for the overall development level of our entire country, and it is a good improvement.

As for the loss to Zhang Xingchen...it can be almost ignored, because Zhang Xingchen will launch an updated version of the lithography machine soon.

Does he still care?

Will not!
"Haha, I guess future generations will evaluate you as the father of modern lithography machines in our country."

Xiaobai said with a smile.

"It's just a false name." Zhang Xingchen said with a smile: "Even if others evaluate me as the father of modern automobiles, the father of modern automatic driving systems, and the father of modern medicine, I don't care at all."

After Xiaobai heard this, many ellipses appeared in his eyes.

Zhang Xingchen stepped forward and patted the lithography machine in front of him, feeling a little emotional: "I never thought that such a small lithography machine would stump so many people."

"I'm in a good mood today, let me introduce our lithography machine to you again."

At this time, Xiaobai started talking endlessly, becoming more and more humane.

There are three ways to operate the lithography machine, one is manual, the other is semi-automatic, and the other is fully automatic.

"The lithography machine I designed can perform manual and fully automatic modes."

Manual does not necessarily mean low precision, and fully automatic is not necessarily synonymous with precision. Different scenarios require different modes to run the lithography machine.

The one that fits is the best.

"In addition, the microscope of the lithography machine is also a very important part. In order to improve the effect of the microscope, we use a 360 five-degree shadowless lamp with no dead ends for illumination."

"And the mirror of the microscope has been polished countless times before it is qualified."

The surface of the mirror is polished to be extremely smooth. As for how flat it is, here is an analogy. The mirror surface we manufactured is magnified fifty times, until it reaches 30 square kilometers.

Even at this time, the error of the flatness of the mirror surface will not exceed one meter.

Here we can use our imagination to fully imagine.
