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

When the file was opened, what was inside was beyond Zhang Rujing's expectations.

A semi-finished packaging design plan.

I only saw a picture at the beginning, which showed multiple chips packaged together.

When seeing this picture, Zhang Rujing's expression suddenly became serious.

Having been engaged in the semiconductor industry for so many years, Zhang Rujing is definitely a top expert in this field.

Even in packaging technology, he has certain insights and accomplishments.

Therefore, it didn't take long for Zhang Rujing to finish reading the picture. After reading it, he didn't rush to express his thoughts, but continued to check the contents of the file below.

The document is not thick, only a few pages.

But just reading these few pages took Zhang Rujing half an hour.

In the end, Zhang Rujing closed the document, a look of disbelief and shock appeared on his face.

Looking up at Wang Donglai, Zhang Rujing couldn't help feeling shocked.

Twenty-one-year-old Tang Du is a full professor at Jiaotong University.

A mathematical genius who has proved many of the world's most difficult mathematical problems and won top awards such as the Fields Medal, the Abel Prize and the Wolf Prize in Mathematics.

In addition, artificial intelligence medical assisted diagnosis systems have also been developed.

It was precisely because Wang Donglai had made so many achievements that Zhang Rujing showed goodwill towards Wang Donglai when they met for the first time.

Faced with Wang Donglai's desire to achieve localization in the semiconductor industry, he also had a very dim hope.

Since their first meeting, Zhang Rujing has also started to pay attention to news about Wang Donglai.

Some time ago, he was the first to know that Wudaokou and Wang Donglai were cooperating to develop artificial intelligence big data.

This was their second meeting, and Zhang Rujing originally wanted to ask Wang Donglai if he had encountered any problems during the research and development process.

But I didn't expect that before I could ask, Wang Donglai threw out such a big surprise.

After reading this semi-finished packaging design plan, Zhang Rujing felt quite complicated.

Emotions such as disbelief, shock, excitement, and thrill are mixed together.

During their last meeting, Wang Donglai only mentioned that he would start with EDA design software. In this regard, Zhang Rujing had no doubt whether the research and development would be successful, because EDA software is not just about successful research and development. It needs to be easy to use and practical, and more importantly, it needs to perform well in actual applications.

The major giants have invested countless amounts of money and talent in this, and through continuous iterations, deep barriers have long been formed.

It is impossible for a new EDA design software to surpass these giants in a short period of time.

but.

The proposal of advanced packaging gave Zhang Rujing hope.

Although what he had in front of him was a semi-finished packaging design plan, it reminded him of four big words.

Overtaking a corner!

The semiconductor industry is an extremely sophisticated and tightly coordinated high-end industry.

It’s the same old saying, from EDA design, to wafer, to lithography, to finished product, there are many steps and processes.

If you want a high-performance chip, you need to do your best at every step.

Encapsulation plays a very important role in this process.

Currently, major domestic manufacturers are able to mass-produce 28nm chips.

At present, Xiaomi Pinecone Surge S1 chip, as the mass-produced chip developed by the second mobile phone manufacturer in China and the fourth in the world, has received a lot of praise in the industry.

As for SMIC, although it also has the ability to manufacture 28nm wafers, Qualcomm started to help SMIC improve the maturity of its 28nm process last year. More than a year has passed, and SMIC has not yet used its own Snapdragon 410 chip in mainstream smartphones.

The Snapdragon 410 chip is just Qualcomm's mid-to-low-end mobile phone chip. It was previously manufactured using TJD's 28nmLP process, which is the lowest-end of TJD's 28nm processes.

In other words, even with the help of Qualcomm, SMIC has not yet mastered the production technology of TJD's lowest-end 28nm process for more than a year.

This shows the gap between domestic semiconductor technology and world-class level.

Right now, 28nm is not considered advanced, and chip manufacturing will inevitably move towards 14nm and 7nm. At that time, packaging technology will become a stumbling block to the advancement of the manufacturing process.

As for why, the reason is also very simple.

Packaging technology becomes more complex as the number of integrated functions on a chip increases.

However, compared with chip research and development, the investment made by the giants in packaging technology, both in terms of manpower and capital, is more than an order of magnitude behind.

Packaging technology will naturally lag far behind chip manufacturing processes.

It is for this reason that Zhang Rujing was shocked when he saw the semi-finished packaging technology that Wang Donglai took out.

"Professor Wang, this packaging technology..."

Zhang Rujing's eyes when he looked at Wang Donglai suddenly became extremely warm, with a hint of anticipation.

Wang Donglai noticed the expectation in Zhang Rujing's eyes, nodded without hesitation, and said, "Mr. Zhang, this is the packaging technology solution I designed, but because of the short time, it is only a semi-finished product for the time being."

"If Mr. Zhang feels that this semi-finished product is not enough, why don't you give me another three hours to complete it?"

Hearing Wang Donglai say this, Zhang Rujing immediately waved his hand and said, "No need, an expert will know whether it is good or not once he takes a look!"

"To be honest, I, an old man, have thought about this before, but it was just a thought because I couldn't do it at all."

"But now that I've seen this design, I know there are always people better than you!"

After hesitating for a moment, Zhang Rujing continued, "Professor Wang, I would like to ask you a question. Did you really develop this yourself?"

"It's not that I don't believe you. It's just that, from what I can see, this packaging technology, although it has not yet been fully demonstrated, has definitely reached 7nm. Even if it is not, it is not much different."

"Based on the idea just now, this packaging technology can indeed make up for the gap between design and process."

Wang Donglai smiled gently. He was not angry at Zhang Rujing's suspicion. Instead, he calmly asked, "Mr. Zhang, if I didn't develop this packaging technology, who else could it be?"

Zhang Rujing actually knew this, but when Wang Donglai suddenly took out a semi-finished product that was suspected to be 7nm packaging technology, he still lost his composure.

However, as time passed, Zhang Rujing soon reacted.

His face showed a deep joy, and he kept saying: "Yes! Yes! Yes!"

He said "good" three times in a row, his excitement beyond words.

Since domestic chip design and process capabilities cannot keep up, we will not compete wholeheartedly in this area, but will find another way.

If an advanced chip has more integrated transistors than ours, then we can just add another chip.

Trade quantity for quality.

This method is actually not complicated, but it is difficult to do.

In the original history, after being sanctioned for several years, Huawei mastered this technology in one fell swoop and immediately returned as the king.

And now, Wang Donglai took the lead in taking out this thing. The shock caused was so great that even Wang Donglai didn't know how the future would develop.

Did the sanctions come early? Or did they happen on schedule?

Or maybe because of the butterfly effect, the target of sanctions has changed to Galaxy Technology?

Wang Donglai had thought about these questions on his way to the Magic City.

Originally, he was not planning to launch so many leading technologies so early, but the factory fire and chip supply disruption made him feel indignant.

Reborn once, with super cheats to rely on.

If he still needs to compromise, he will feel unhappy.

The trend of the times is rolling forward, and the revival of the dragon is unstoppable!

"Mr. Zhang, now that we have this packaging technology, what do you think of the solution I proposed earlier?"

"To be honest, I personally prefer Zhang Lao to be in charge. I don't feel comfortable with other people, and I don't want to hand it over to those companies."

Faced with Wang Donglai's invitation, the joy on Zhang Rujing's face slowly disappeared and he began to ponder.

Silence and hesitation.

After a long while, Zhang Rujing finally said, "Professor Wang, you know, I have withdrawn from SMIC now, and I may not be able to help you."

"Mr. Zhang, as a junior, there are some things I shouldn't say, but I really think your efforts are not worth it."

"What is lost must be taken back!"

"You have contributed a lot to SMIC's success, but you left SMIC. This is unreasonable and should not happen!"

"Mr. Zhang, what do you think of the advanced packaging technology I proposed?" Wang Donglai asked.

"good, very good!"

"With this advanced packaging technology, can we catch up with the performance of some mainstream chips?" Wang Donglai asked again.

"Although I haven't done any tests, I think there is a 70% chance that it can catch up with mainstream mid-to-high-end chips, and a 30% chance that it can match the performance of high-end chips."

"I can develop advanced packaging technology, so is Mr. Zhang willing to believe that I can develop more technologies?" Wang Donglai asked again.

This time, Zhang Rujing hesitated for a moment before nodding and saying, "I believe it!"

"Okay, since Mr. Zhang is willing to believe in my R&D capabilities, then why are you unwilling to cooperate with me? Let's work together to contribute to domestic semiconductors. The Xinsheng Semiconductor founded by Mr. Zhang in Shanghai is mainly engaged in silicon wafer R&D and mass production. This makes up for the important shortcomings of the domestic semiconductor industry in silicon materials, which is of great significance."

"But, in my opinion, Mr. Zhang's ability is far more than that. The localization of semiconductors across the entire industry chain is a huge and systematic project."

"Foreign giants will not just watch us make breakthroughs. They may not care about breakthroughs in some unimportant or non-core fields, but they will never relax in the field of lithography."

"This is a good opportunity, Mr. Zhang. As long as advanced packaging technology can be realized, we can take a bite of meat from the hands of foreign giants, which is enough for us to live a comfortable life."

"The investment in semiconductors is enormous. We cannot just think about raising funds and attracting investment. Instead, we should be more independent and use trade to support research and development. This is the right path to take, combining technology, industry and trade!"

Wang Donglai spoke rapidly and immediately began to persuade Zhang Rujing.

As Galaxy Technology expands its business and involves more and more fields, it needs more elite talents to join in.

No matter how you look at it, a big shot like Zhang Rujing is the most suitable.

It's not just Zhang Rujing, there are also Academician Yao and Academician Ni from Wudaokou and others.

These are undoubtedly top talents, and their technical level is naturally no problem.

Although they are old and their scientific research capabilities have weakened, they have extremely rich experience. The energy that can be mobilized by bringing these talents together is unimaginable.

What's more, these academicians have a large number of students and disciples.

Wang Donglai didn’t plan to do this before because he wanted to wait a little longer.

But he didn't want to wait anymore.

The dragon emerges from the abyss and the tiger descends from the mountain to eat meat.

After Wang Dong finished speaking, Zhang Rujing fell into silence.

Seeing this, Wang Donglai did not rush Zhang Rujing to give an answer.

"Mr. Zhang, you can take your time to think about this matter."

"However, we still need to conduct experiments to see whether the advanced packaging solution can achieve our goal. So, Mr. Zhang will not refuse this, right?"

Wang Donglai said with a smile.

Zhang Rujing also sorted out his thoughts and said with a smile: "I have no problem with this. Although I have withdrawn from SMIC, I can still do this. I will gather the team tonight. However, if you want to experiment, this packaging design plan must be completed first."

"It won't be too late to conduct experiments after you apply for a patent."

When talking about this, Zhang Rujing's eyes lit up and his whole mental state became different from before.

If he was an introverted technical researcher before, now he is an outgoing warrior.

Noticing the changes in Zhang Rujing, Wang Donglai's lips curled up slightly.

"Mr. Zhang, how long will the trial production take at the fastest?" Wang Donglai asked.

Zhang Rujing said without hesitation: "One month is enough to complete the tape-out!"

"Snapped!"

Wang Donglai clapped his hands vigorously and said with a smile, "Okay."

"Then I will wait for good news from Mr. Zhang. As for this packaging design plan, I will hand it over to Mr. Zhang tomorrow."

Zhang Rujing was also a little surprised and asked, "Professor Wang, is what you just said true?"

"Of course it's true. If I didn't have the diamond, I wouldn't dare to take on this porcelain job!" Wang Donglai said with a smile.

"How is the development of the EDA design software you mentioned earlier going?" Zhang Rujing asked again.

"The general structure has been completed, and we are currently filling in the modules. If things go well, it may only take a month to develop it successfully!"

Wang Donglai only completed a rough outline of the EDA design software and handed it to the programmers of Galaxy Technology.

We can't let him, as the boss, do everything.

He has already completed the most important things, and the other things can be used to train his employees.

"hiss……"

Zhang Rujing looked a little shocked. He didn't think Wang Donglai would lie to him about this.

Because these things can be easily exposed and are completely unnecessary.

So, after being shocked, he couldn't help but recall what Wang Donglai had just said.

Gradually, a seed took root and sprouted in Zhang Rujing's heart. (End of this chapter)
