As time goes by, Ye Hua has powerfully integrated the most cutting-edge talents in the entire semiconductor alliance to form a heaven-level research assistant team, and all the talents from other semiconductor companies have been lent to him.
The research base is at the Zifeng Research and Innovation Center. The tasks assigned to Ye Hua by Xiang Yuansheng have also been completed. The R&D center has been established. Now the research assistant team is basically in place. The next task is to focus on technology.
However, Ye Hua did not focus all his energy on the scientific research team, because the troubles of Coastline Company are still there and have not disappeared. Although he is not worried, the current situation is that Coastline's crisis has not been resolved yet.
It's getting more and more fierce.
Especially when he announced the birth of this new semiconductor industry alliance, outsiders thought that Ye Hua was going to completely break up with Silicon Valley and American partners.
The media at home and abroad are exaggerating a series of words such as Yongzhen vs. Silicon Valley, Huaxia Semiconductor vs. American Semiconductor, falling out, going all out, overestimating one's capabilities, a new king ascending the throne, the dynasty being permanent, etc.
When the melon-eating public saw these news, it seemed as if the two sides were completely at odds and wanted to fight each other to the death.
However, none of this affected Ye Hua's established arrangements.
In the following time, he frequently traveled back and forth between Shangdu and Zifeng Research and Innovation Center. Ye Hua was a little stressed, after all, he was regarded as the hope of the whole village.
Allies believe that even with Ye Hua taking the lead, even if a miracle occurs in the semiconductor industry, it will take three or even five years to achieve a breakthrough.
After all, integrated circuits are really too complex, and the requirements for manufacturing processes are also extremely demanding. Huawei had already begun laying out integrated circuits 15 years ago, but it has only begun to see results now. That is still spending an average of 3 to 5 billion yuan every year.
The situation of burning out US dollars of R&D funds.
The annual revenue of other domestic semiconductor companies is less than half of Huawei HiSilicon's investment in semiconductor R&D. Some semiconductor companies are even among the top in the country but their revenue is only 3 to 4 billion yuan.
It can be seen how difficult it is to pass the semiconductor level.
However, Ye Hua's ambition is so great that all his allies can't even dream of it, because his inner expectation is that not only will he achieve a breakthrough in about half a year, but he will also be able to supply the market, that is, after the PHC is used up.
Before the final investment is made, the chip supply can be connected.
Ye Hua did not tell them the goal he had set, because his goal was too exaggerated. Telling it would make his partners think you were unreliable. After all, if you want to get it done in half a year, what is the difference between this and cheating...
…
The basic material source of integrated circuit devices in the world today is the application of silicon, but Ye Hua gave up the application of silicon and chose a new super material, tin.
To be precise, it is a two-dimensional stanene material.
The superconductivity of tin has been discovered for more than a hundred years, but this phenomenon only exists in white tin (β-sn).
Another common phase of tin is gray tin (a-sn), which is a semimetal and does not have superconductivity.
In recent years, people have realized that gray tin is a topological insulator.
Scholar Zhang Shousheng predicted back then that a single layer of gray tin along a special direction of the crystal, that is, two-dimensional stanene, has a hexagonal structure similar to graphene and may have a series of important properties such as the greenhouse quantum spin Hall effect.
Topological properties.
His prediction has not been confirmed yet, but his prediction is correct because it corresponds to the knowledge in Ye Hua's mind, and the development he is doing is to turn his prediction into reality.
The first major thing Ye Hua did was to master the production technology of two-dimensional stanene. Now he has the best integrated circuit development research assistant team in the country and even the world under his command. He wants to realize this technology that is surpassed by anyone within half a year.
Crazy goals that everyone thinks are impossible to achieve must be developed simultaneously and in parallel.
There are a number of teams for the production of two-dimensional stanene, and there is another team for carrying out extremely low-temperature electrical and magnetic transport measurements on stanene films.
More than 60% of the entire huge research assistant team are from friendly businessmen, and the rest are from Coastline Company. Coastline's technical engineers worship Ye Hua blindly, because only by experiencing it can you understand why.
Admire him so much.
At first, the new batch of scientific research engineers from friendly companies were not used to Ye Hua's research style. They felt as if they were helping out. They came here with great ambitions and even hoped to take charge of the research of a topic.
.
However, Ye Hua directly gave them the data and conclusions, and gave them work to verify his conclusions through experiments. After all, any theory must withstand experimental verification or falsification in order to become the truth and be firmly believed by the world.
Otherwise it can only be a hypothesis.
Unexpectedly, they found in subsequent experiments that stanene films with a thickness of two atomic layers or more have two-dimensional superconductivity. This is the first time that superconductivity has been experimentally confirmed in gray tin.
This is an exciting breakthrough.
Subsequent experimental studies showed that the density of states of stanene was modulated by the substrate, leading to the emergence of superconductivity.
By changing the thickness of the substrate, the transformation of stanene from a single-band superconductor to a double-band superconductor was also achieved. What is even more exciting for the team is that the epitaxially grown stanene film is extremely stable and has superconductivity without any protective layer.
Can be maintained for a long time.
As for the specific length of time, it will take time to verify. There is no way to do this. To get the actual data, we can only wait.
But Ye Hua once again gave them a surprising conclusion: its superconductivity can be maintained for 28 months.
The new group of scientific researchers from friendly companies were skeptical at first, but previous verifications made them doubt themselves.
In the days that followed, they discovered for the first time that it was so easy to engage in research and development, and so many results had been verified in such a short period of time.
It's not easy to see a ghost.
If they used to do scientific research on their own, they had to solve a problem step by step, but now Ye Hua gives them the conclusion and then goes to the experiment. This is equivalent to copying the answer for you in the exam.
How could it not be easy?
Then this group of people gradually fell into blind worship of Ye Hua, because facts speak louder than words.
According to the laws of mankind's past scientific history, at this point in time, it is indeed time for a scientific god-level figure like von Neumann and Dirac to appear.
The members of the research assistant team increasingly feel that Ye Hua is the one, and may be more terrifying than those great scientists in history.
Although the research assistant team was pleasantly surprised to have obtained so many verification results in such a short period of time, compared with achieving complete autonomy and supplying products to the market, this has just begun. If the entire goal is 100%, then what has been achieved now
The result is only 3%, which shows the difficulty of integrated circuits. If Ye Hua didn't cheat, he would not dare to boast in front of so many domestic semiconductor giants.
However, everything is difficult at the beginning. As for this task, if it starts well, it will get smoother and smoother later on. Because the upstream end is solved, the research assistant team will be disbanded immediately, and then distributed, ic design will be done, and ic design, packaging and testing will be carried out.
To carry out packaging and testing, all links in the entire integrated circuit industry chain are carried out simultaneously.
The major companies that have joined the CSAC Semiconductor Industry Alliance have concluded a unique rule, that is, only members within the system can obtain priority supply rights. In fact, Ye Hua followed the example of the Dutch lithography machine company Esmore (
asml) mode.
Of course I have to borrow other people's models. Ye Hua is not a pedantic person.
The rule of ASML is that only by investing in ASML can you get priority supply rights. Chinese people are not included in this. There is no way. The Chinese people exclude rabbits because they have the ability of "Sharingan".
Simply put, ASML requires its own customers to invest in itself first. This special cooperation model allows ASML to obtain a large amount of funds, including Intel, Samsung, TSMC, and Hynix, which all have considerable shares in ASML. It can be said that the world
Most of the semiconductor industry is "relatives" of ASML, and they are basically "relatives", which forms a huge community of interests.
ASML uses investment methods to maintain this model, but Coastline is definitely not going to work, because Ye Hua is a rich and skilled owner, but he lacks helpers, and reliable helpers.
But a living person cannot be suffocated to death by a bird. Changes will work, so Ye Hua chose another method to maintain it, that is, patent technology barriers.
That is to say: in the csac semiconductor club system, all patent barriers are cleared, and then the watermelon is cut and divided. Only members of the system can have priority in obtaining supply rights, thus forming a huge community of interests.
Of course, as the development progress progresses, Coastline Company's share of core technology mastery is expanding, but Ye Hua still has a relentless pursuit of core technology.
However, the watermelon has been cut, and Coastline Company promises to only take one piece. As long as the other allies do not withdraw from the group, their interests will not be harmed, at least they will not be targeted by Coastline Company.
After all, you, Coastline, are everyone’s default alliance leader, or you, Ye Hua, are the person in charge of the CSAC system.
Ye Hua naturally knows how difficult it is to gather a group, and how easy it is to break up a group. For example, as long as the person in charge is unfair, a seemingly unbreakable alliance will instantly fall apart, and other participants will have problems.
It's a small problem. If you kick it out and someone will take its vacated position immediately, the injustice of the party in charge will greatly reduce the credibility of the entire system.
But this time, it was possible to gather sand and form a tower so quickly, and CSAC was born this way. The right time, right place, and people are all indispensable.

Let’s make this book a bit fresher and more refined. The author said that the last book, including many other scientific articles, basically included graphene, and it’s almost ruined. In this book, we won’t play with graphene anymore. We will play with stanene. Don’t do it.
I think it’s nonsense. The technologies that have appeared in this book so far are all cutting-edge and popular, and stanene is a cutting-edge project of basic materials. It is also Zhang Shousheng’s prediction. Maybe future integrated circuits will replace silicon materials with stanene instead of graphite.
Tinene, because current research shows that tinene is better than graphene.)
