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

time flies.

Soon it was time for Wang Donglai to prepare to hold a semiconductor academic research conference.

Because Galaxy Technology had announced that it had developed domestic EDA software, coupled with the excellent performance of its advanced packaging design solutions, and Zhang Rujing had invited us.

So there are quite a few people attending this academic conference this time.

Among them are people working in the semiconductor field, as well as people sent by companies in the digital field.

North China Huachuang, Zhongwei, Shengmei Magic City, Tuojin Technology, Huahai Qingke, Changchuan Technology, HuaDa JiuTian, ​​Founder, Sanan, etc.

It is worth mentioning that the combined market value of these companies is not as high as Galaxy Technology’s market valuation.

Although semiconductors are high-tech, the valuations of these domestic companies are very low because their technology lags behind the international advanced level.

When the time comes.

Wang Donglai didn't show any modesty and immediately went on stage holding the microphone.

"Today, I invited you all here for two main purposes."

"One is the groundless accusations and slanders against the International EDA Alliance and foreign EDA software companies. I have entrusted a law firm to collect evidence, conduct a fair investigation, and file a lawsuit."

"It is true that our domestic semiconductor level is not as high as that of foreign countries, but this does not mean that we will never develop."

"If you know me, you will know that in addition to coming up with advanced packaging design solutions, I also solved the problem of the etcher, so I do have some talent in the semiconductor field."

"Many people are curious about how the advanced packaging design was designed and why I was able to achieve a breakthrough in the field of packaging and lead the world."

"The reason is simple, because in the field of semiconductors, some technological breakthroughs are not that difficult."

"So I hope to work with you to jointly complete the localization of the semiconductor technology industry chain, narrow the technology gap to one generation, and then slowly catch up."

No one expected that Wang Donglai would be so direct.

There was no grand promise or passionate speech, but he simply expressed his ideas in a straightforward manner.

We will work with domestic manufacturers to achieve technological breakthroughs and reduce the number of generations to one generation.

This is simply a dream.

Zhang Rujing was also feeling complicated at the moment. Although he had guessed that such a situation might occur, he was still a little surprised when it really happened.

Secondly, Zhang Rujing didn’t think Wang Donglai would succeed.

Because the principle is simple, everyone can shout slogans, but when it comes to taking action, you need to spend real money to do research.

There was silence in the hall for a moment, and then someone stood up and said loudly: "Boss Wang, please tell me the second thing!"

After this person finished speaking, a burst of laughter suddenly broke out in the hall.

Obviously, not many people were optimistic about Wang Donglai's suggestion, and no one took it seriously.

Wang Donglai was not surprised, so he said, "I haven't finished what I just said, please don't be impatient, guest."

"There are 6 billion in working capital in Galaxy Technology's bank account. Please note that this is working capital excluding employee salaries and supplier payables. It is not running water."

When Wang Donglai revealed that Galaxy Technology had 6 billion in its company account, there were exclamations from below.

This amount of money has exceeded the company valuation of many people.

"The reason I mentioned the six billion is to strengthen my resolve and to reassure everyone."

"Tangdu City will vigorously develop the semiconductor industry and build a semiconductor industrial park. The Galaxy Technology Group has become the Galaxy Technology Semiconductor Company and Laboratory, and will overcome the difficulties in the semiconductor field."

"In the next three years, Galaxy Technology initially plans to continue to invest at least 5 billion in research and development funds."

With every word Wang Donglai spoke, the people below became more shocked.

The wolf is coming!
This was the thought that emerged in everyone's mind at this moment.

Galaxy Technology has already demonstrated its scientific research capabilities, and everyone has seen it.

If the investment is really as huge as Wang Donglai said, it is hard to imagine what terrible the consequences will be.

It is very likely that most of the companies present will be squeezed out of business.

Therefore, the people who had been somewhat careless and unconcerned before now all had serious expressions, with worry between their brows.

"The first thing is this, and then the second thing will come."

The first thing was such a big deal, and everyone became curious, wondering what Wang Donglai’s second thing would be.

As I was thinking about it, I heard Wang Donglai's voice.

"The second thing is easy."

"This is the EDA software I developed. I named it Hetu."

"To express my support for the domestic semiconductor industry, I hereby announce that Hetu EDA software will be free for domestic semiconductor companies and will not charge any fees in the future."

As Wang Donglai finished his words, a software icon appeared on the huge screen behind him. It was the Hetu software.

The news announced by Wang Donglai also shocked everyone present.

After hearing the first thing, everyone subconsciously thought that the second thing might be more important, but they didn't expect that this was not the case.

Wang Donglai actually does it for free.

However, everyone soon realized that this was probably due to the average performance of the Hetu EDA software.

After being singled out for questioning by the International EDA Alliance, Galaxy Technology had no choice but to release its own Hetu software, and in order to expand its user base, it chose to make it free.

When you think about it this way, the logic is rigorous and reasonable.

While everyone was thinking this, Wang Donglai spoke again.

"After talking about these two things, let's start academic exchanges. I will start by explaining the ideas of advanced packaging design."

As Wang Donglai said this, the originally noisy hall suddenly became extremely quiet.

Everyone was curious about Wang Donglai's development of advanced packaging design solutions.

Now, everyone had a chance to hear Wang Donglai share his ideas, so they naturally would not miss it and all pricked up their ears to listen.

"We are all insiders, so I won't explain some simple concepts."

"The existence of Moore's Law means that the development and manufacturing costs of advanced processes will become increasingly higher, and iterations will take longer. This will result in a large number of companies being unable to manufacture chips with higher process capabilities, leading to an artificial monopoly."

"In the post-Moore's Law era where process technology development is limited, advanced packaging technology optimizes the interconnection between chips and achieves breakthroughs in computing power, power consumption and integration at the system level. It is an important development direction to break through Moore's Law." "Advanced packaging includes four major elements: Bump, RDL (rewiring), 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."

“Traditional chips use wires to achieve electrical connections between chip PADs and frames, while advanced packaging uses bumps/bumps instead of wires for connection, thus shortening the current path and physical size.”

"..."

"Rewiring technology can realize pin re-layout to meet more chip pin requirements. RDL rewiring technology can realize horizontal interconnection of chips, re-plan the connection path, change the position and arrangement of I/O pads in the initial design of the chip, and adjust it to a new interconnection structure."

"..."

“Advanced packaging technologies such as 3D stacking and 2.5D integration rely on wafers as a foundation to achieve higher integration. In advanced packaging, the wafer is not only a carrier for the chip, but also a medium for interconnect technologies such as RDL and TSV, which enable more complex circuit layouts and higher I/O density at the wafer level.”

"..."

"TSV, on the other hand, creates vertical vias between chips and wafers and fills them with conductive materials such as metal to achieve vertical interconnection of chips. First, deep reactive ion etching (DRIE) is used to make TSV holes, plasma enhanced chemical vapor deposition (PECVD) is used to make dielectric layers, physical vapor deposition (PVD) is used to make barrier layers and seed layers, copper (Cu) is electroplated to fill holes, and chemical mechanical polishing (CMP) is used to remove excess metal. In 3D integration, wafer thinning and thin-wafer bonding are also required."

"..."

Wang Donglai spoke eloquently on the stage, and the people below listened attentively.

Some people listened with fascination, sometimes they had an epiphany, sometimes they were confused.

Some people are completely confused, as if they are listening to a foreign language.

To be honest, such scenes rarely appear in the domestic environment.

The reason is very simple, because real technical personnel have put all their energy into technology research and development. They will never stay in management positions, and will not continue to develop technology after becoming a boss.

Another reason is that domestic companies do not actually attach much importance to technology or 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 capabilities and is the founder of the company.

So, this style of painting was formed.

Wang Donglai’s sharing of ideas did not last too long, and it was over in half an hour.

This time, Wang Donglai did not deliberately hide his skills, but showed them off generously.

Advanced packaging technology is important, but not that important.

This is important because the current backward situation of domestic semiconductors allows us to catch up with chip performance to a certain extent through advanced packaging technology.

It is less important because chip manufacturing processes will continue to develop, while the development space for advanced packaging technology is very limited.

Wang Donglai has never given up the idea of ​​achieving a comprehensive breakthrough in semiconductor technology.

Breakthroughs must be achieved in everything from silicon crystals to packaging technology, etching equipment, photoresist, lithography machines, etc.

He has the confidence in this, so he is not afraid of other domestic manufacturers making breakthroughs.

There is no way to make enough money, and it is impossible for one company to completely monopolize the market.

After Wang Donglai develops more advanced technology, he will sell some of the backward technology.

At present, just talking about your own research and development ideas can also serve as a screening role.

If there is really a company that can achieve a technological breakthrough based on Wang Donglai’s sharing, this is the company that Wang Donglai really wants to see.

Under the leadership of Wang Donglai, bigwigs such as Zhang Rujing also came on stage to share their academic ideas, and this academic exchange meeting was quite successful.

But, until the end.

Not many people took the initiative to come to Wang Donglai to discuss cooperation.

On the contrary, there are many people who want to get investment from Wang Donglai. There is no doubt that these people are eyeing the money in the account of Galaxy Technology Semiconductor Company.

"How is it? Are you disappointed?"

Zhang Rujing walked to Wang Donglai and asked curiously.

Wang Donglai shook his head and said nothing.

"You don't look disappointed. Could it be that you are here just for academic exchange?"

Zhang Rujing became even more curious. He had no idea what Wang Donglai was thinking and wondered if he had guessed wrong.

"Mr. Zhang, are you willing to cooperate with Galaxy Technology?"

Wang Donglai did not answer Zhang Rujing's question, but instead asked this question.

Zhang Rujing thought for a moment before saying, "Of course there is no problem with cooperation, but it depends on what kind of cooperation it is."

"That is to say, Mr. Zhang doesn't really believe that I can achieve a technological breakthrough? Break the foreign monopoly?"

Wang Donglai asked directly without any concealment.

Zhang Rujing was silent for a moment before nodding and saying, "I believe in your scientific research ability, but the semiconductor field is different. There are too many industry fields involved. It is the most complex process in the world today. It is a complex process completed by many top companies."

“The semiconductor manufacturing process is very complex and has thousands of steps. It is extremely complex and demanding.”

"With your ability, you can achieve a breakthrough in etching technology and develop EDA software, but this is far from enough. Wafer manufacturing, lithography, 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, we need to build our own wafer fab, and so on. These are all things that need to be considered."

“And that increases the risk.”

Having said this, Zhang Rujing did not continue speaking, but his meaning was clear.

Wang Donglai was not discouraged at all, but said with a smile: "Mr. Zhang's words are very pertinent. I know it is true, but I believe that success depends on human effort."

"Technological breakthroughs are made one by one, little by little, day by day, and we will achieve technological breakthroughs sooner or later."

“There are risks, but the rewards are staggering once you succeed.”

"As a scientific researcher, I trust my brain and hands more."

"Mr. Zhang, I am still very optimistic about you leading Xinsheng Semiconductor to research silicon materials. I also hope that Mr. Zhang can develop it as soon as possible and contribute to the development of domestic semiconductors together!"

Zhang Rujing heard Wang Donglai's firm belief, and the more he admired him, the more he felt a little sorry. He asked, "Okay, what are you going to do next?"

"Mr. Zhang, this is a confidential project. You will know when the time comes!"

Wang Donglai kept everyone in suspense and did not reveal his next plan. (End of this chapter)
