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

After visiting Zhongwei Company, Wang Donglai did not say anything, but said goodbye to Yin Zhiyao directly and took Chen Lingyue to SMIC.

But before leaving, Wang Donglai said something to Yin Zhiyao.

When they were talking, only Wang Donglai and Yin Zhiyao were present, so even Chen Lingyue didn't know what Wang Donglai said. He just noticed that Yin Zhiyao had a strange expression on his face when he was seeing Wang Donglai off.

Xinsheng Semiconductor.

Like Yin Zhiyao of Zhongwei, Zhang Rujing was also waiting for Wang Donglai at the company's door.

He was wearing glasses and although he looked a little old, he looked quite energetic.

Although they had only met once, Zhang Rujing and Wang Donglai were far from being good friends regardless of age difference.

However, Wang Donglai's ideas and opinions on the semiconductor industry still made Zhang Rujing, the big boss, place Wang Donglai in a special position in his heart.

After several decades of life, Zhang Rujing still believes in his own judgment of people.

He may not really think that Wang Donglai would succeed, but he never suspected that Wang Donglai was cheating.

Even if it is just for this vague possibility, Zhang Rukyo is willing to provide all the support he can.

After meeting and exchanging brief greetings, Zhang Rujing took Wang Donglai on a tour.

The last time the two met, they talked a lot.

During this meeting, Wang Donglai did not clearly state his purpose, and Zhang Rujing did not ask.

Taking Wang Dong to visit the company is an essential procedure.

Wearing dust-free suits, under the guidance of Zhang Rujing, they came to the core production workshop of Xinsheng Semiconductor Company.

The reputation of being a major infrastructure country is not earned for nothing.

There is no need to say more about the support Shanghai gives to Zhang Rujing.

Green light all the way.

In the newly built production workshop, Zhang Rujing looked quite excited.

Wang Donglai could also understand Zhang Rujing's excitement. With the support of Magic City, Xinsheng Semiconductor had a good start, so all its equipment was more advanced.

"Professor Wang, is your company planning to develop technology, then become a supplier and collect patent fees, or is it planning to do a one-stop service involving the entire industry chain, building a factory, production, and sales?"

Zhang Rujing asked directly.

Wang Donglai didn't take it seriously, and said with a smile: "I used to plan to get involved in the entire industry chain, but now my thoughts have changed a little bit."

"Oh, what's changed?"

Zhang Rujing asked Wang Donglai curiously.

"Before, I wanted to get involved in the entire industry chain, so that I could get more profits, and at the same time, I could better feed back to the domestic market and have higher and more autonomy."

"This is a good idea. If it can be done, it will have a lot of benefits."

"However, the only drawback is that it is too difficult to really do this."

"In addition, this process will be affected by unexpected off-field factors."

"I believe that Mr. Zhang probably knows the news about Samsung, the chip supplier of Galaxy Technology, right?"

"The factory caught fire. That's a lame excuse."

"I've strayed off topic. I've said too much..."

Wang Donglai didn't finish what he was saying, he stopped halfway through.

Zhang Rujing didn't think much about it and just continued speaking along with what Wang Donglai said.

"This is the result of our backwardness. If we had the same product, no, not even the same grade, as long as we had such a product, they would not be so arrogant, and such an outrageous thing would not happen."

"It's just a pity that we don't have it, so we can only beg them."

"Professor Wang, this is not the first time something like this has happened, and it won't be the last. When our country's semiconductor industry catches up with the level of developed countries in the world, then that will be the day when we can really be proud of ourselves."

"But I don't know when this day will come!"

Zhang Rujing has been in the industry for so many years that he knows much more than Wang Donglai.

When he brought it up, his tone was full of anger and helplessness.

Because Xinsheng Semiconductor is still in the first phase of construction, there are not many places to visit.

But even so, Wang Donglai truly saw the unique charm of this pearl of modern technology.

Each process is the pinnacle of contemporary technology.

After the tour, Wang Donglai and Zhang Rujing came to the office.

"Professor Wang, what are you doing here this time?"

After sitting down, Zhang Rujing asked directly to the point.

Wang Donglai was somewhat surprised by this frankness. He did not expect Zhang Rujing to ask this question on his own initiative.

Wang Donglai knew very well what this meant.

If Zhang Rujing didn't really think highly of him, he wouldn't have needed to ask. Although it seemed like just a simple inquiry, it actually revealed Zhang Rujing's goodwill.

If Wang Donglai came to visit Zhang Rujing this time because he really needed Zhang Rujing's help, Wang Donglai had no doubt that Zhang Rujing would agree.

You know, this is only the second time the two have met.

"call!"

Wang Donglai let out a long breath, a hint of determination in his eyes.

"Mr. Zhang, I think you should also know that the Galaxy Technology Company I founded has projects such as artificial intelligence and drones, which have high and more requirements for chips."

"The fire at the Samsung factory has changed my mindset."

"Since Samsung can't provide chips, I can only change to another manufacturer. TJD and Qualcomm are both options, but I don't want to choose these manufacturers. The reason is very simple. I don't trust them. I would rather hand it over to domestic manufacturers."

"If Mr. Zhang were still here, I would definitely choose SMIC without hesitation. However, since Mr. Zhang is no longer here, I have no reason to choose SMIC."

Hearing Wang Donglai say this, Zhang Rujing remained very calm and did not lose his mind because of Wang Donglai's flattery.

"I'm more curious about the status of your company's artificial intelligence and drone technology. Professor Wang, can you introduce it to me?"

Zhang Rujing did not react to Wang Donglai's exaggeration. Instead, he asked about the development of artificial intelligence technology and drones, as well as the demand for chips.

Wang Donglai felt relieved. Although Zhang Rujing didn't say anything else, as long as he mentioned the chip, that was enough.

Therefore, the design plan of neural network, deep learning, high intelligence, inlaid with multiple modules, which can achieve real-time high-definition image transmission and autonomous obstacle avoidance functions was proposed.

The former is aimed at artificial intelligence and simply stacks computing power, which is a wrong path.

However, without advanced chips, it will not work at all, so specially designed chips are needed to meet the needs.

It's like a drone.

The civilian version is developed based on inspiration from model airplanes, but the other version is different, with more research and development technology and higher requirements.

When Zhang Rujing heard the design plan proposed by Wang Donglai, a hint of surprise appeared on his face and he glanced at Wang Donglai.

Zhang Rujing felt very strange about the trust shown by Wang Donglai.

It was clearly only the second time the two met, but he felt as if they had known each other for a long time.

There is a feeling of gentlemanly friendship.

Putting this thought deep in his heart, Zhang Rujing began to recall the design plan mentioned by Wang Dongli, and at the same time thought about what kind of chip should be used.

The more he thought about it, the more surprised Zhang Rujing's face became.

After a moment of silence, Zhang Rujing said with some disappointment, "Professor Wang, if this is your request, it is probably impossible to meet it with SMIC's current design and production capabilities."

“As for other domestic manufacturers, based on my understanding, it may be difficult as well!”

"If you don't want to be influenced by foreign capital like Samsung, I recommend you choose TJD. It is the most suitable choice."

When talking about TJD, Zhang Rujing's tone was normal, with no other changes.

However, Wang Donglai could hear a hint of complexity in Zhang Rujing's tone.

Although Wang Donglai was somewhat surprised by the kindness shown by Zhang Rujing, after thinking about it carefully, he felt that it was expected.

However, Wang Donglai shook his head at Zhang Rujing's suggestion and said, "Mr. Zhang, I didn't come to you for this matter."

"No matter how good TJD is, it is not as good as SMIC in mainland China, and what I want is to see more advanced technologies appear in the mainland."

Zhang Rujing asked directly: "So, what do you need me to help you with?"

"Mr. Zhang, I have an idea, I hope you can help me with it!"

"Since domestic manufacturers lack chip design and process capabilities, can we make up for it with more advanced packaging technology?"

Wang Donglai looked at Zhang Rujing and asked this question.

"Of course there is no problem with this. You must be well aware of the production steps in the semiconductor industry. It is an overall process, not a separate job. It involves many aspects. Design and process are part of the factors. However, if the packaging technology is more advanced, it can actually make up for the shortcomings of design and process."

"only……"

Speaking of this, how could Zhang Rujing not understand Wang Donglai's thoughts.

After hesitating for a while, he said, "There is no problem in theory, but it is only theory after all. If we want to surpass others in packaging technology, then the packaging technology must be much more advanced than a little bit, and only then can we make up for the gap."

"If you want to do this, to be honest, I don't think it's a good idea!"

It can be said that Zhang Rujing’s rejection and pessimism were also within Wang Donglai’s expectations.

When he asked this question, he knew Zhang Rujing would say this.

However, Wang Donglai had already made up his mind and would not be affected by it.

"Mr. Zhang, since the theory can be done, then the next thing is very simple. I wonder if Mr. Zhang is willing to work with me to accomplish this."

"Actually, I thought about inviting Mr. Zhang last time, but I didn't dare to ask."

Zhang Rujing laughed softly and asked calmly, "Professor Wang is also a researcher, so he should understand how difficult it is to implement something that is theoretically feasible."

"If you want to use advanced packaging technology to make up for the shortcomings of design and process, this requires very high, even abnormal, advanced packaging technology."

“Is Professor Wang going to study DIP technology, QFP/PFP technology, PGA technology, or BGA technology?”

"Technology is constantly developing. Even if Professor Wang really figures it out, how many years will it take?"

"What if we succeed in developing a new chip and the chip manufacturing process improves? Should we continue the research or just sit back and watch the huge R&D funds go down the drain?"

"Professor Wang, you are a young man with many ideas and high energy. Your scientific research ability is also at its peak. You may think this kind of thing is very cool."

"But in addition to being a scientific researcher, you are also the CEO of a company. You should consider the costs and risks."

"So, I refuse your invitation!"

Zhang Rujing's words were spoken with great sincerity. If it were someone else, Zhang Rujing would have probably kicked the person out by now.

I won't waste my time and energy trying to persuade you.

Wang Donglai naturally understood Zhang Rujing's kindness and good intentions.

The semiconductor industry has become the core.

It's just that it's so important.

There are many processes involved in turning sand into chips.

From a wafer to a finished product, it is not enough to just do photolithography, it also requires packaging.

Package refers to the shell used to install semiconductor integrated circuit chips. It not only plays the role of placing, fixing, sealing, protecting the chip and enhancing thermal conductivity, but also serves as a bridge to communicate the internal world of the chip with the external circuit - the contacts on the chip are connected to the pins of the package shell with wires, and these pins are connected to other devices through wires on the printed circuit board.

Therefore, packaging technology is a very critical link for many integrated circuit products.

As a result, very high requirements are placed on packaging technology.

For example, the ratio of chip area to package area should be as close to 1:1 as possible.

The pins should be as short as possible to reduce delays, and the distance between pins should be as far as possible to ensure no interference and improve performance.

Based on the heat dissipation requirements, the thinner the package, the better.

It is conceivable that such a small chip, no bigger than a fingernail, has such requirements just for the packaging technology.

As an important component of a computer, the performance of the CPU directly affects the overall performance of the computer.

The last step in the CPU manufacturing process, which is also the most critical step, is the CPU packaging. The same CPU will have a large difference in performance if different packaging technologies are used.

As a result, semiconductor giants have never stopped researching packaging technology.

If Zhang Rujing didn't have a good impression of Wang Donglai, he would have known Wang Donglai's academic achievements and knew that he was not an uneducated person.

I'm afraid that when Wang Donglai first proposed to develop more advanced packaging technology to make up for the gap in design and process capabilities, Zhang Rukyo would have kicked him out.

This was undoubtedly a joke and a challenge to his expertise.

There will be no more detailed explanation.

Wang Donglai knew all of this.

Therefore, after Zhang Rujing finished speaking, Wang Donglai's expression did not change much, but he still kept smiling and said, "Mr. Zhang, why don't you take a look at this document first!"

As he spoke, Wang Donglai took out a document and handed it to Zhang Rujing.

As soon as he saw the contents of the document for the first time, Zhang Rujing's eyes lit up and his expression became serious and focused.

He never thought that Wang Donglai would actually take out this thing.

But he no longer had much energy to think about this problem, and was completely focused on the contents of the document.

Because, this document is exactly... (End of this chapter)
