Time passes.
Soon it was time for Wang Donglai to prepare to hold a semiconductor academic research conference.
Because of the news that Galaxy Technology has developed domestic EDA software, coupled with the excellent performance of advanced packaging design solutions, and Zhang Rujing’s invitation.
So there are not a few people attending this academic conference this time.
Among them are people working in the semiconductor field, as well as people from companies in the digital field.
Northern Huachuang, Zhongwei, Shengmei Magic City, Tuojin Technology, Huahai Qingke, Changchuan Technology, BGI Jiutian, Founder, Sanan, etc.
It is worth mentioning that the combined market value of these companies is not as high as the market valuation of Galaxy Technology.
Although semiconductors are high-tech, the valuation of these domestic companies is very low because the technology lags behind the international advanced level.
The time is up.
Wang Donglai was not modest and immediately stepped onto the stage holding the microphone.
"Today, I invite you all here for two main purposes."
"One is to target the International EDA Alliance and foreign EDA software companies for their unfounded accusations and slander. I have entrusted a law firm to collect evidence. Be fair and prosecute."
"Our domestic semiconductor field is indeed not as high as foreign countries, but this does not mean that we will never develop. "
"If you know about it, you will know that in addition to developing advanced packaging design solutions, I also solved the problem of etching machines, so I still have some talent in the semiconductor field. "
“Many people are curious about how advanced packaging design solutions are designed. Why can I achieve a breakthrough in the field of packaging and lead the international level.”
“The reason is very simple, because in the semiconductor field, some technological breakthroughs are not that difficult.”
“So I hope to work with you to complete the localization of the semiconductor technology industry chain and bring the technology to the next generation. The gap will be reduced to one generation, and then we will catch up slowly."
No one expected that Wang Donglai would be so direct.
I didn’t draw a pie or make an impassioned speech, but I expressed my thoughts in a straightforward manner.
Work with domestic manufacturers to achieve technological breakthroughs and reduce agency inspections to one generation.
This is simply a dream.
Zhang Rujing was in a complicated mood at the moment. Although he had somewhat guessed that such a situation might happen, he was still a little surprised when it actually happened.
Secondly, Zhang Rujing did not think Wang Donglai would succeed.
Because the reason is very simple, everyone can shout slogans, but when it comes to doing things, you need to spend real money to do research.
In the hall, there was silence for a while, and then someone stood up and said loudly: "Mr. Wang, please tell me the second thing!"
After this person finished speaking, there was a burst of laughter in the hall.
Obviously, not many people are optimistic about Wang Donglai's suggestion, and no one takes it seriously.
Wang Donglai was not surprised, so he said aloud: "I haven't finished what I just said, please don't worry, this guest."
"Galaxy Technology's bank account has sixty Billions of working capital, please note that this is working capital excluding employee wages and supplier payables, not running water.”
When Wang Donglai broke the news that Galaxy Technology’s company account had 6 billion. At this time, there was an exclamation from below.
This amount of money has exceeded many people’s company valuations.
“The reason why I mentioned these six billion is to strengthen my determination and to reassure everyone.”
“Tangdu will vigorously develop the semiconductor industry and will build Semiconductor Industrial Park, and Galaxy Technology Group has become Galaxy Technology Semiconductor Company and Experimental "In the next three years, Galaxy Technology initially plans to invest at least 5 billion in research and development."
Every time Wang Donglai said something, everyone below was more shocked.
The wolf is coming!
This is the thought that comes to everyone's mind at this moment.
Galaxy Technology has shown its own scientific research strength, and everyone has noticed it.
If the investment is really as big as what Wang Donglai said, it is unimaginable what terrible consequences it will be.
It is very likely that most of the companies present will be squeezed out of business.
Therefore, everyone who was a little careless and didn't take it seriously before now also had solemn expressions on their faces, with worries on their brows.
"The first thing is this, and then we will talk about the second thing."
The first thing is such a big deal, and everyone is even more curious, no What should the second thing be like after knowing Wang Donglai.
Thinking about it, I heard Wang Donglai’s voice.
“The second thing is very simple.”
"This is the EDA software I developed, and I named it Hetu."
"In order to express my support for the domestic semiconductor industry, I hereby announce that Hetu EDA software will support the domestic semiconductor industry." The semiconductor company is doing it for free, and there will be no subsequent charges.”
As Wang Donglai finished speaking, a software icon appeared on the huge screen behind him, which was Hetu Software.
The news announced by Wang Donglai also shocked everyone present.
After hearing the first thing, everyone subconsciously felt that the second thing might be more important, but they did not expect that this was not the case.
Wang Donglai actually did it for free.
However, everyone quickly realized that this was probably due to the average performance of the Hetu EDA software.
Being called out and questioned by the International EDA Alliance, Galaxy Technology had to come up with its own Hetu software, and in order to expand its users, it chose to make it free.
Thinking about it this way, the logic is strict and reasonable.
While everyone was thinking this, Wang Donglai spoke again.
"After talking about these two things, we will start the academic exchange. I will first introduce ideas and explain the advanced packaging design ideas."
As Wang Donglai said these words, the originally noisy hall suddenly changed. Got to be extremely quiet.
Everyone is curious about the advanced packaging design scheme developed by Wang Donglai.
Now, Wang Donglai finally had the opportunity to share his thoughts. Naturally, everyone would not miss it and pricked up their ears to listen.
“We are all insiders, so I won’t go into some simple concepts.”
"The existence of Moore's Law means that the development and manufacturing costs of advanced processes will become higher and higher, and iterations will also take longer. This will result in a large number of companies being unable to manufacture higher process chips, resulting in artificial Monopoly."
"In production. In the post-Moore's Law era where the development of process technology is limited, advanced packaging technology achieves breakthroughs in computing power, power consumption and integration at the system level by optimizing interconnections between chips, which is an important development direction to break through Moore's Law. The package includes Bump (bump/bump ), RDL (rewiring), Wafer (wafer)/WLP, and TSV (through silicon via). The combination of the four elements forms different processes, such as flip chip/FC, wafer level packaging/WLP, 2.5D, 3D packaging, etc.”
< br>
“Traditional chips realize the electrical connection between the chip PAD and the frame through wires, while advanced packaging uses bumps/bumps instead of wires for connection, thereby shortening the current path and physical size.”
"..."
"Rewiring technology can realize the rearrangement of pins to meet the needs of more chip pins. RDL rewiring technology can realize the horizontal interconnection of chips, re-plan the wiring path, and change the I/O pad position and the initial design of the chip. Arrange, adjust to new interconnection structure "
"..."
“Advanced packaging technologies such as 3D stacking and 2.5D integration rely on wafers as the basis to achieve higher integration. In advanced packaging, wafers are not only the carrier of chips, but also serve as interconnects such as RDL and TSV. media for connectivity technologies that enable more complex circuit layouts and higher "
"..."
"And TSV makes vertical vias between chips and wafers and fills them with metal. and other conductive materials to realize chip vertical interconnection. First, deep reactive ion etching (DRIE) is used to make TSV holes, etc. Ion-enhanced chemical vapor deposition (PECVD) is used to make the dielectric layer, physical vapor deposition (PVD) is used to make the barrier layer and seed layer, electroplating copper (Cu) is used to fill the holes, and chemical mechanical polishing (CMP) is used to remove excess metal during 3D integration. Wafer thinning and thin die bonding are also required.”
"..."
Wang Donglai was talking eloquently on the stage, and everyone below was listening attentively.
Some people are fascinated by it, sometimes suddenly enlightened, sometimes confused.
Some people are completely confused, as if they were listening to a book from heaven.
To be honest, in the domestic environment, such a scene rarely appears.
The reason is also very simple, because real technicians have put all their energy into technology research and development and will not stay in management positions at all, let alone continue to develop technology after becoming bosses.
There is another reason, that is, domestic companies actually do not attach much importance to technology, nor to technical talents.
If you don’t do it, others will!
This sentence is deeply engraved in the bones of the Chinese people.
But Wang Donglai is different. He has strong technical strength and is the founder of the company.
Therefore, this style of painting was formed.
Wang Donglai’s sharing of ideas did not last long, it was over in half an hour.
In sharing this time, Wang Donglai did not deliberately hide his secrets, but openly showed his true abilities.
Advanced packaging technology is very important, but it is not that important.
The important thing is that because of the backward semiconductor status in China, chip performance can be caught up to a certain extent due to advanced packaging technology.
It is not so important because the chip manufacturing process will continue to develop, but the development space of advanced packaging technology is very limited.
Wang Donglai has never given up the idea of achieving a comprehensive breakthrough in semiconductor technology.
From silicon crystals, to packaging technology, to etching equipment, photoresist, photolithography machines, etc., breakthroughs must be made.
In this regard, he also has this confidence, so he is not afraid of other domestic manufacturers making breakthroughs.
Money is not enough, and the market cannot be completely monopolized by one company.
After Wang Donglai develops more advanced technologies, he will sell some backward technologies.
At the moment, just talking about your own research and development ideas can also play a screening role.
If there is really a company that can achieve technological breakthroughs from Wang Donglai’s sharing, such a company is the company that Wang Donglai really wants to see.
Led by Wang Donglai, Zhang Rujing and other big names also came to the stage to share academic exchanges. This academic exchange meeting was quite successful.
But, until the end.
Few people took the initiative to come to discuss cooperation with Wang Donglai.
On the contrary, there are many people who want to get investment from Wang Dong here. There is no doubt that these people are interested in the money in Galaxy Technology Semiconductor Company's account.
"How was it? Do you feel disappointed?"
Zhang Rujing walked to Wang Donglai's side and asked curiously.
Wang Donglai shook his head and said nothing.
"Looking at you, it doesn't look like you are disappointed. Could it be that you are doing this just for a purely academic exchange?"
Zhang Rujing became even more curious, completely unsure of what Wang Donglai was thinking, and secretly wondering if he should Maybe I guessed wrong.
"Mr. Zhang, are you willing to cooperate with Galaxy Technology?"
Wang Donglai did not answer Zhang Rujing's question, but asked this question.
Zhang Rujing thought for a while and then said: "There is no problem with cooperation, but it depends on what kind of cooperation it is."
"In other words, Mr. Zhang actually doesn't really believe that I will complete a technological breakthrough? Break the foreign monopoly?"
Wang Donglai asked directly without any cover.
Zhang Rujing was silent for a moment, then nodded and said: "I believe in your scientific research strength, but the semiconductor field is different. There are too many industries involved. It is the most complex process in the world today. This is a process composed of many A complex process completed by top companies.”
“There are many semiconductor manufacturing processes, thousands of steps, and it is extremely complicated. , the requirements are also very high. ”
“With your strength, you can complete a breakthrough in etching technology and develop EDA software, but this is not enough. wafer manufacturing, photolithography, ion implantation, Thin film deposition, packaging and testing require not only a large amount of technical reserves, but also a large number of qualified employees and massive capital investment. ”
"For example, if you want to build your own wafer factory, etc., these are all things that need to be considered."
"And in this way, the risk will increase."
Speaking of which , Zhang Rujing did not continue speaking, but his meaning was already made clear.
Wang Donglai did not feel discouraged at all, but said with a smile: "What Mr. Zhang said is very pertinent. I know it is the truth, but I believe that everything depends on man-made efforts."
"Technological breakthroughs are made one after another, accumulated bit by bit, and each day we make progress, we will complete technological breakthroughs sooner or later."
"There are risks, but the benefits once successful are also amazing."
"As a scientific researcher, I trust my brain and hands more."
"Mr. Zhang, you lead Xin Sheng I am still very optimistic about the research on silicon materials for semiconductors. I also hope that Mr. Zhang can develop it as soon as possible and work together to contribute to the domestic semiconductor industry. Conduct your part!”
Zhang Rujing heard Wang Donglai’s firm belief, and the more he appreciated it, the more he felt a little pity, and asked aloud: “Okay, what are you going to do next? ?”
“Mr. Zhang, this is a confidential project, you will know when the time comes”
Wang Donglai gave it up and didn't say his next plan. (End of this chapter)
