When I am reborn, I just want to be a top student

Chapter 232 Ambition emerges, the gap between the world’s top leaders

"Currently, the dry etching process mainly includes three options: ion milling etching, plasma etching and reactive ion etching."

"Among these three solutions, ion milling and etching are the simplest, with relatively high controllability and high technological maturity. In fact, almost all relevant patents have been applied for. If you want to overtake in a corner, avoid Western patents. Patent barriers, this solution is very difficult.”

"In addition, this solution also has the shortcomings of the technology itself, that is, the etching selectivity is extremely poor, and special etching endpoint detection technology must be used. The etching rate is also relatively low, and the cost performance is quite low."

"As for plasma etching, although better etching selectivity and higher etching rate can be obtained by selecting and controlling the composition of the discharge gas, the etching accuracy is not high and can generally only be used in areas larger than 4- In the process of 5 micron lines.”

"And the ongoing project in our experiment is the reactive ion etching plan designed by Mr. Wang!"

As Chen Lingyue introduced, he led Yin Zhiyao and others toward the etching plan project area.

After hearing Chen Lingyue's introduction, Yin Zhiyao's expression did not change much.

He had already read the paper. Although he was a little surprised by Wang Donglai's quick action and directly verified it in his own laboratory, if that was all, it could only be regarded as average and quite satisfactory.

In fact, not only Wang Donglai but also Chen Lingyue could see Yin Zhiyao's inner thoughts.

Choosing the appropriate gas composition can not only achieve ideal etching selectivity and speed, but also shorten the lifetime of the active groups, which effectively suppresses side effects caused by the diffusion of these groups near the film surface. directional reaction, greatly improving the anisotropic characteristics of etching.

Moreover, the information revealed in the paper also made Yin Zhiyao full of expectations.

He looked at the instrument without blinking.

As a boss who has been immersed in the etching industry for decades, Yin Zhiyao constantly evaluates this laboratory in his heart.

Logically speaking, in fact, facing the etching plan designed by Wang Donglai, one should not be so excited and take it seriously.

When Wang Donglai, Chen Lingyue and others saw Yin Zhiyao's performance, they couldn't help but feel a little admiration for Yin Zhiyao.

As an old expert who has been immersed in this industry for decades, he has actually developed many advanced etching solutions.

After all, it is really good that someone at such an old age can still maintain such a mentality towards technology.

This etching process has both physical and chemical effects. Glow discharge is performed under a low vacuum of a few tenths to tens of Pascals. The silicon wafer is at the cathode potential. Most of the potential during discharge falls near the cathode, and a large amount of electricity is charged. The particles are accelerated by the electric field perpendicular to the surface of the silicon wafer, are vertically incident on the surface of the silicon wafer, and are physically etched with a large momentum. At the same time, they also undergo a strong chemical reaction with the surface of the film to produce chemical etching.

Because of a very simple truth, the further technology develops, the greater the constraints it encounters and the more things it needs to avoid.

And now, Yin Zhiyao has these instruments in front of him.

Because he has determined that Wang Donglai's etching plan is indeed qualified, even excellent.

Yin Zhiyao, on the other hand, immediately wanted to go in and see the result, so he looked at Wang Donglai and was about to ask for advice.

It has to be said that when faced with this aspect, Yin Zhiyao's love was extremely sincere and enthusiastic.

After the operator repeatedly checked that everything was correct, Chen Lingyue ordered the verification to begin.

There have been so many etching solutions. If people want to avoid them later, they need more knowledge reserves and the design needs to be more sophisticated.

Modern dry etching equipment includes complex mechanical, electrical and vacuum devices, and is also equipped with automated etching endpoint detection and control devices. It is expensive and few laboratories are fully equipped.

It's just an etching process, and it doesn't actually take long.

Before Yin Zhiyao could say anything, Wang Donglai nodded and said, "Mr. Yin is an expert in this field. You can check it out!"

When he saw the experimental project, Yin Zhiyao became extremely serious.

At this moment, Yin Zhiyao wanted to take off his eyes and put them on to see, so as not to miss any key information.

But this is not the case.

When Wang Donglai was conceiving the plan, he originally thought of just coming up with an ion etching plan. However, in the state of [brain overclocking], he had countless inspirations and developed a brand new reactive ion etching plan.

After reading Wang Donglai's paper, Yin Zhiyao has already concluded that Wang Donglai is a genius in this field.

As for the principle of reactive ion etching, it is quite simple.

After the design was completed, it was sent to Chen Lingyue for verification in the laboratory.

It took half an hour to check.

The more he looked, the more Yin Zhiyao was amazed.

So, soon the instrument stopped.

After almost two days of equipment adjustment, today is the time for verification.

We were speechless all the way, and we quickly arrived at the place.

The machine hummed softly, and the instrument suddenly began to move.

After putting down the finished product, Yin Zhiyao's eyes were extremely bright.

Wang Donglai is full of confidence and not afraid of any problems.

"Buzz!"

Therefore, at this moment, Yin Zhiyao can be said to have used his greatest energy to observe and check.

Yin Zhiyao was not polite, nodded, immediately walked in and started checking.

"It seems that Galaxy Technology is still willing to invest in this area!"

To be honest, if Chen Lingyue had not joined Galaxy Technology, it would have taken more than half a year or even longer to put together these instruments.

Reactive ion etching is also a promising etching method in the VLSI process.

These instruments are currently being manually repaired and adjusted to verify Wang Donglai's reactive ion etching plan.

It's not like a design that just appeared, it's more like a mature solution that has been running for many years, and there's nothing picky about it at all.

perfect!

This can only be used to describe it.

After making his judgment in his mind, Yin Zhiyao was both excited and nervous.

The excitement is that through this design plan, he can clearly say that there is no big problem in the localization of etching equipment.

The tension lies in the fact that Wang Donglai's performance has made him, the boss of Zhongwei Company, a little worried about the development of his company.

After all, he already knew that Wang Donglai's Galaxy Technology would develop in the semiconductor industry.

With such a leader to overcome difficulties, he knew very well what would happen.

Because that's how he came here in the beginning.

"Mr. Yin, what do you think?"

Wang Donglai came over and asked with a smile.

"Mr. Wang, compared with you, I feel that my life has been in vain these past few decades, and my future life is terrible!" Yin Zhiyao did not hide his attitude at all, and said mockingly with a wry smile on his face.

"If that's the case, then Mr. Yin might as well go for a walk with me?"

Wang Donglai stretched out his hand and invited Yin Zhiyao.

"it is good!"

Yin Zhiyao was not stupid, so he naturally understood that Wang Donglai must have something important to say when he invited him like this.

Ever since, the two of them started wandering around the laboratory again.

Artificial intelligence medical projects, lithium battery projects, drone projects...

Walking through each project area, Wang Donglai also gave a brief introduction to Yin Zhiyao.

Finally, after returning to the office, Yin Zhiyao gradually began to ponder Wang Donglai's thoughts and plans.

"Mr. Wang, please don't tell secrets. Yesterday you said you wanted to work together. What plan did you follow?"

Yin Zhiyao didn't hide it and asked directly.

Because he knew that he was at a disadvantage and had little room for bargaining.

It does not mean that without this design plan, your company will go bankrupt and cannot continue to operate.

It's just that the development of our own company is slower and it will be a few years later to make a profit.

However, now that he has seen Wang Donglai's strong ability to design plans, he will naturally not let go of this opportunity.

In the business field, no one wants to have one more competitor.

Wang Donglai was not surprised that Yin Zhiyao took the initiative to ask. On the contrary, he expected it.

"Mr. Yin, how do you think the domestic semiconductor industry should develop better?"

Wang Donglai did not answer Yin Zhiyao's question directly, but asked another question.

Yin Zhiyao was stunned for a moment before speaking out: "In fact, there are already many semiconductor equipment companies in China. From lithography machines to wafer fabs to chip design, there are companies that are developing silently."

"Although there is still a big gap compared with foreign countries in some fields, the problem of starting from scratch has been solved. Next, we only need to invest heavily in funds and talents, and then slowly catch up through the accumulation of time, we can still catch up. ”

"Our country has a large population. With a huge population base, there are also a lot of corresponding talents. The speed of catching up should not be too slow."

Just as Yin Zhiyao was saying this, Wang Donglai suddenly interrupted Yin Zhiyao's words.

"How many years does Mr. Yin think it will take to catch up?"

Yin Zhiyao didn't care that Wang Donglai interrupted his speech. He pondered for a moment and then gave a time and said: "If it's fast, we can catch up in thirty years. If it's slow, it's almost fifty years."

At this time, it was not Yin Zhiyao's nonsense, but his judgment as a veteran in the industry based on what he knew.

At present, domestic lithography machines and other fields are lagging behind the 20 years of technology accumulation of foreign companies. The country is catching up, and foreign countries are also making progress. If everything goes well, it will naturally not take only 20 years to catch up.

In this regard, Yin Zhiyao took into account the prerequisites of strong national support and investment of large amounts of funds and talents in research and development.

Without these prerequisites, the pace of catching up will only be slower.

"Mr. Yin, thirty or fifty years is too long. Life is short, so seize the day!"

"Furthermore, if the time is extended to thirty to fifty years, who dares to say that there were no other changes in such a long period of time."

"In my opinion, the West may not give us such a long time to catch up. Looking at how many accusations and prosecutions your company has suffered in just a few years of development, you can see what they think."

"The country imports hundreds of billions of semiconductors every year. This market is really too big. They won't just watch us break through safely."

"Patent barriers and technical sanctions are all foreseeable."

"I wonder if Mr. Yin thinks what I said makes sense?"

After Wang Dong finished speaking, he looked at Yin Zhiyao quietly, waiting for his answer.

Yin Zhiyao has been abroad for so many years, so he naturally knows the styles of these companies.

In particular, after he returned to China, he was successively sued by his two old employers, Linlin and Applied Materials, which had already made him thoroughly see the true face of these large companies that claimed to be free and democratic.

In these two lawsuits, if he hadn't been on guard from the beginning and avoided patent disputes, Zhongwei Company would have been crushed and bankrupt.

Even so, Yin Zhiyao didn't think they would let him go. They were definitely still staring at him, always ready to take a bite.

However, even knowing this, Yin Zhiyao didn't really want to agree with Wang Donglai's thoughts.

Wang Donglai's meaning was clearly understood by Yin Zhiyao through these words.

They just want to join forces to overcome difficulties together, localize it, and avoid Western patent restrictions!
The idea is a good idea, but it is unrealistic.

With this thought in his mind, Yin Zhiyao spoke.

"What Mr. Wang said makes sense. Western companies are indeed like this. They rely on patent barriers and their mastery of advanced technology to sell us twice as many products and earn a lot of wealth."

"They cut off people's wealth and kill their parents. The country's hundreds of billions of imports every year are meat on their plates. They don't allow others to get involved. If they find that someone intends to take it away, they will immediately attract a thunderous strike! Although this industry cannot be said to be monopolized by a few of them, it is definitely controlled by a few of them and no new top giant companies are allowed to emerge. "

"Mr. Wang, trying to localize the product is tantamount to snatching food from a tiger's mouth. It's very difficult!"

Yin Zhiyao shook his head and didn't say anything clearly, but he seemed to have said everything.

"I understand what Mr. Yin said."

Wang Donglai actually thought that Yin Zhiyao would reject his proposal, but he seemed very calm.

The atmosphere in the office also became a little quiet at this time.

"Mr. Wang, we are all Chinese. Since Mr. Wang has such ambitions, I will naturally strongly support him. I may not be able to help in other fields, but in terms of etching, we at Zhongwei are doing our part."

"In this regard, I think we have a lot of room for cooperation. I wonder what Mr. Wang will do?"

Yin Zhiyao smiled and said to Wang Donglai aloud, as if nothing had happened just now.

"Okay, since Mr. Yin is interested, we can discuss the price of this etching plan."

Wang Donglai didn't care and expressed his thoughts immediately.

Immediately, the two started business negotiations in the office.

The original price of two million was doubled.

At the same time, the two also reached certain agreements and agreements.
