The file was opened, and the contents inside were beyond Zhang Rujing's expectation.
A semi-finished packaging design plan.
I only saw the first picture, which showed multiple chips packaged together.
When he saw this picture, Zhang Rujing's expression suddenly became serious.
Having been involved in the semiconductor industry for so many years, Zhang Rujing is definitely a top expert in this field.
Even in packaging technology, there is a certain amount of knowledge and attainments.
So, it didn’t take long for Zhang Rujing to read through the picture. After reading it, he was not in a hurry to express his thoughts, but continued to check the content of the file below.
The document is not thick, only a few pages.
But Zhang Rujing read the contents of these pages for half an hour.
At the end, Zhang Rujing closed the document, with a hint of disbelief and a hint of shock on his face.
Looking up at Wang Donglai, Zhang Rujing couldn't help but feel a little shocked.
Twenty-one-year-old professor at Jiaotong University in Tangdu.
A mathematical genius who has proven many of the world's 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 auxiliary diagnosis systems have also been developed and so on.
It is precisely because Wang Donglai has made so many achievements that Zhang Rujing showed goodwill to Wang Donglai when they met for the first time.
Faced with Wang Donglai's desire to complete localization of the semiconductor industry, he also had extremely dim expectations.
After the first meeting, Zhang Rujing also paid attention to the news about Wang Donglai.
Some time ago, he learned about the news that Wudaokou and Wang Donglai were cooperating to develop artificial intelligence big data.
This is the second meeting. Zhang Rujing originally wanted to ask Wang Donglai if he encountered any problems during the research and development process.
But I didn’t expect that before I could ask, Wang Donglai would throw out such a big surprise.
After reading this semi-finished packaging design plan, Zhang Rujing felt quite complicated.
Disbelief, shock, excitement, excitement and other emotions are mixed together.
In the last meeting, Wang Donglai just said that he would start with EDA design software. In this regard, Zhang Rujing did not doubt whether the development would be successful, because EDA software does not just need to be successfully developed. It needs to be easy to use and practical, and more emphasis is placed on performance in practical applications.
The major giants have invested countless funds and talents in this. After continuous iteration, deep barriers have long been formed.
It is simply impossible for a new EDA design software to surpass these giants in a short 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 in corners!
The semiconductor industry is an extremely precise and closely coordinated high-end industry field.
As the old saying goes, from EDA design, to wafer, to photolithography, 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 also plays a great role in this process.
At present, the chips that major domestic manufacturers can mass-produce are 28nm.
Currently, Xiaomi SongguoPaper S1 chip, as the second domestic and fourth mass-produced chip developed by mobile phone manufacturers in the world, has received a lot of praise in the industry.
As for SMIC, although it also has 28nm process wafer manufacturing capabilities, since last year, Qualcomm has helped SMIC improve the maturity of the 28nm process. More than a year has passed, and now, SMIC has not made its own Snapdragon 410. Chips are used in mainstream smartphones.
The Snapdragon 410 chip is just Qualcomm's low-end and mid-range mobile phone chip. It was previously manufactured in TJD's 28nmLP process, and the 28nmLP process is the lowest-end process of TJD's 28nm process.
In other words, SMIC, with the help of Qualcomm, has not mastered the approximate level production technology of TJD's lowest-end 28nm process for more than a year.
It can be seen that there is a gap between domestic semiconductor technology and the world's first-class level.
Right now, 28nm is not considered advanced, and the chip manufacturing process will inevitably move towards 14nm and 7nm. By then, packaging technology will become a roadblock restricting the progress of the manufacturing process.
As for why, the reason is also very simple.
Packaging technology will become more complex as chips integrate more functions.
However, compared to the research and development of chips, the investment of giants in packaging technology, whether in terms of manpower or funds, is more than an order of magnitude behind.
Packaging technology will naturally lag behind the chip manufacturing process.
It was precisely for this reason that Zhang Rujing was shocked when he saw the semi-finished packaging technology presented by Wang Donglai.
"Professor Wang, this packaging technology..."
Zhang Rujing's eyes when he looked at Wang Donglai suddenly became extremely enthusiastic, with a hint of expectation.
Wang Donglai noticed the expectation in Zhang Rujing's eyes, nodded without any hesitation, and said: "Mr. Zhang, this is the packaging technology solution I designed, but because the time is too short, it is only a semi-finished product for the time being. ."
"If Mr. Zhang feels If this semi-finished product is not enough, how about giving me another three hours to complete the semi-finished product?"
Hearing what Wang Donglai said, Zhang Rujing immediately waved his hand and said: " No need, an expert will know if it’s there as soon as he takes action!”
"To be honest, I, an old man, have thought about this before, but I just thought about it because I simply can't do it."
"But now after seeing this design plan, I know that there is a way out there. There is someone out there!”
After hesitating for a moment, Zhang Rujing continued: “Professor Wang, let me ask you, did you really develop this yourself? "
"It's not that I don't believe you, it's actually this packaging technology. From my perspective, although it has not been fully demonstrated, it has definitely reached 7nm. Even if it is less than Not much different.”
“According to the idea just now, this kind of packaging technology can indeed bridge the gap between design and manufacturing process.”
Wang Donglai smiled softly, and was not angry because of Zhang Rujing's suspicion. Instead, he calmly asked: "Mr. Zhang, if I didn't develop this packaging technology, who else would it be?"
< br>Zhang Rujing actually knew this, but Wang Donglai suddenly took out a semi-finished piece of suspected 7nm packaging technology, which still made him lose his sense.
However, as time passed, Zhang Rujing soon came to his senses.
There was a lot of joy on his face, and he said repeatedly: "Okay! Okay! Okay!"
I said "yes" three times in a row, and my excitement was beyond words.
Since domestic chip design and process capabilities cannot keep up, we will not compete in this area, but find another way.
An advanced chip integrates more transistors than ours, so we will install one more chip.
Quantity for quality.
This method is actually not complicated, but it is difficult to do it.
In the original history, Warwick conquered this technology in one fell swoop after being sanctioned for several years, and suddenly the king returned.
Now, Wang Donglai was the first to take out this thing. The shock caused by it, even Wang Donglai didn't know how it would develop in the future.
Are sanctions coming early? Or does it happen on time?
Or is it because of the butterfly effect that the target of sanctions was changed to Galaxy Technology?
Wang Donglai had thought about these questions on the way to the Magic City.
Originally, he was not prepared to launch so many leading technologies so early, but the factory caught fire and the supply of chips was cut off, which made him unhappy.
Rebirth once, and there are super cheats around.
If he still needs to compromise, he is not in a good mood.
The times are moving 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 before?"
"To be honest, I personally prefer Zhang Laolai to take charge. If it were someone else, I wouldn't trust it, and I wouldn't want to hand it over to those companies."
Faced with Wang Donglai's invitation, Zhang Rujing's face His joy slowly disappeared and he began to think deeply.
Silence, hesitation.
After a while, Zhang Rujing said: "Professor Wang, you know, I have quit SMIC now, and I may not be able to help you."
"Zhang Lao, as a junior, there are some things I shouldn’t say, but I really feel that your efforts, Mr. Zhang, are not worth it.”
"What is lost must be taken back!"
"You are largely responsible for SMIC's success, but you left SMIC as a result. This is unreasonable and should not be done!"
"Mr. Zhang, what do you think of the advanced packaging technology I proposed?" Wang Donglai asked aloud.
“Okay, very good!”
“So with this advanced packaging technology, can it catch up with the performance of some mainstream chips?” Wang Donglai asked again.
"Although I haven't done any testing, I think I'm 70% sure that I can catch up with mainstream mid-to-high-end chips, and 30% sure that I 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 just hesitated for a moment, nodded and said: "I believe it!"
"Okay, since Mr. Zhang is willing to believe in my R&D capabilities, why don't you want to work with me? Work together? Let us work together to contribute to domestic semiconductors. Xinsheng Semiconductor, founded by Mr. Zhang in Shanghai, is If we are to carry out the research and development and mass production of silicon wafers, this will make up for the important shortcomings of the domestic semiconductor industry in silicon materials, which is of great significance.”
“However, in my opinion, Mr. Zhang’s ability is far beyond that. Far more than that, the localization of semiconductors in the entire industry chain is a great project of a huge system.”
"Foreign giants will not just watch us complete breakthroughs. They may not care about some unimportant or non-core R&D breakthroughs in fields, but in the field of lithography, they will never relax."
< br>"There is a good opportunity now, Mr. Zhang. As long as advanced packaging technology can be realized, then we can take a bite out of the hands of foreign giants." A mouthful of meat is enough to keep us alive.”
“The amount of money invested in semiconductors is huge. We can’t just think about financing and attracting investment, but we should be more independent and trade. Supporting research and development and following the path of technology, industry and trade is the right thing to do!”
Wang Donglai spoke eloquently and immediately began to persuade Zhang Rujing.
Galaxy Technology's stall is getting bigger and bigger, and it involves more and more fields, so more elite talents are needed to join.
And no matter how you look at it, a boss like Zhang Rujing is the most suitable.
Not only Zhang Rujing, but also Academicians Yao and Ni from Wudaokou.
These are undoubtedly top talents, and there is no problem with their technical level.
Although his scientific research capabilities have weakened as he gets older, his experience is extremely rich. The energy that can be harnessed by bringing these talents together is unimaginable.
What's more, these academician bosses have a lot of students and disciples.
Wang Donglai didn't intend to do this before because he wanted to wait.
But, he doesn'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 was not in a hurry to ask Zhang Rujing to give an answer.
"Mr. Zhang, you can think about this matter slowly and think about it slowly."
"However, whether the advanced packaging solution can achieve our vision still requires experiments, so on this point, Mr. Zhang should You won’t refuse, right?”
Wang Donglai said with a smile.
Zhang Rujing also collected his thoughts and said with a smile: "Of course I have no problem with this. Although I quit SMIC, I can still do this. Tonight I Just gather the team, but if you want to experiment, you have to complete the package design first. "
"For this, it is not too late to conduct experiments after you apply for the patent."
When he said this, Zhang Rujing's eyes shone, and his whole mental state was different from before.
If he was a restrained technical developer before, now he is an outgoing warrior.
Noticing Zhang Rujing's change, Wang Donglai's lips curled up slightly.
"Mr. Zhang, how long will it take at the earliest for trial production?" Wang Donglai asked aloud.
Zhang Rujing said without hesitation: "One month is enough to complete the tape-out!"
"Pa!"
Wang Donglai clapped his hands hard and said with a smile: "Okay."
"Then I will wait for the good news from Mr. Zhang. As for this packaging design plan, tomorrow I will give it to Mr. Zhang."
Zhang Rujing was also a little surprised and said, "Professor Wang, is what you just said true?"
"Of course it is true, if not. Diamond, I wouldn’t dare take this porcelain job!” Wang Donglai said with a smile.
"So how is the development of the EDA design software you mentioned before?" Zhang Rujing asked again.
“The general architecture has been completed, and modules are currently being filled in. If we go quickly, it may only take a month to successfully develop it!”
EDA design software Wang Donglai only completed a rough outline and threw it to A programmer from Galaxy Technology.
We can't let him, the boss, do everything.
He has completed the most important things, and the other things are just used to temper the employees.
"Hiss..."
Zhang Rujing's eyes were a little shocked. He didn't think Wang Donglai would lie to him about this.
Because these things are easy to expose, it is completely unnecessary.
So, after being shocked, he couldn't help but recall what Wang Donglai said just now.
Gradually, a seed took root and sprouted in Zhang Rujing's heart. (End of chapter)
