Global monopoly of technology

Just now a group of scholars exchanged academic ideas, and everyone spoke freely, almost neglecting Luo Sheng.

Only then did he come back to his senses and realized that Luo Sheng is not only an entrepreneur who is proficient in business, but also has a greater hidden attribute, that is, a technical expert.

Luo Sheng obviously didn’t finish. He stared at the revised mathematical model and continued: “One more thing, since all the silicon in the depletion layer is inserted into a layer of oxide, then why have to put a bunch of useless ones? Is the silicon underneath? Wouldn’t it be better to make another gate directly under the oxide layer with the channel sandwiched on both sides?"

Everyone was stunned for a while, and after regaining their senses, they all shot the case, and Luo Sheng added: "This is not enough. If this is the case, why should I have to bury the oxide in the silicon? I can completely get the silicon out. Wrap the insulating layer like a sandwich, and put the grid on the outside. Isn’t it exciting?"

A semiconductor research scholar said with great excitement: "It is simply a genius-like idea. Such a scheme not only greatly reduces the leakage current, but also because there is one more gate, the two gates are generally connected together. Therefore, it is equivalent to greatly increasing the capacitance of the insulating layer mentioned above, which is also greatly improving the switching performance of the transistor. I dare to make a decision. This tri-gate transistor is definitely a revolutionary advancement in the architecture. , Not only 45 nanometers, but also 32 nanometers, 22 nanometers, and 14 nanometers, there is great room for imagination, which is another victory of Moore's Law."

It is worth mentioning that the evolution of process nodes in the semiconductor industry can be predicted, and Moore's Law has also emerged, which is how many nanometers of next-generation chips are.

For example, 130 nanometers, 90 nanometers, 65 nanometers, 45 nanometers, 32 nanometers, 22 nanometers, 14 nanometers, 10 nanometers, 7 nanometers (5 nanometers), you will find that this is a geometric sequence with a ratio of about 0.7, which is why .

But this is just a naming convention, and there is still a gap with the actual size.

At this moment, all the research scholars present at the meeting are very excited, but some people have returned to rationality after the excitement.

A scholar tactically held the mirror and said: "This is a genius design. Basically, I don't need supercomputer simulation to verify that I dare to judge that it is feasible, but it is difficult to realize this idea. Why? Because of the erected part. Silicon, that is, the silicon used as the channel, is too thin, less than 10 nanometers, not only far smaller than the smallest size of the transistor (currently), but also far smaller than the smallest size that can be engraved by the current most precise photolithography machine How to get this plan out is the real problem."

As soon as this remark came out, the other excited researchers also calmed down.

Yes, this problem cannot be avoided. In the end, I went around and returned to the problem of lithography machines. At present, the most sophisticated lithography machines can’t be dealt with. Moreover, it is impossible for Hua Guo to buy the most advanced ones. Lithography equipment.

At present, Huaxin International is the domestic leader in this field, but it is helpless that foreigners are already able to mass-produce 32-nanometer chips, while Huaxin International does not even produce 65-nanometer chips. This is still introducing In the case of a lithography machine, I can't make a lithography machine with a 65-nanometer process.

Luo Sheng smiled and said: "Everyone is wrong. It takes a lot of process flow charts to introduce it in detail, but the basic principle is that this part of silicon is not etched, but grown. It uses ordinary precision lithography first. Create a pile of'shelf', and then deposit a layer of silicon, then a thin layer of silicon will grow on the edge of the shelf, and then selectively etch to remove the excess material, and the rest is these It’s so simple."

When everyone heard such a method, everyone was stunned for a long time.

Kneeling completely, this IQ is too crushing.

Seeing that everyone was speechless, Luo Sheng could not help but smiled and added: "In fact, this physical model of tri-gate and ring-gate transistors can be traced back to around 2000. Professor Hu Zhengming of Berkeley, this was the first one he proposed. , But no one has realized it so far, but this scheme can be realized."

Xu Zhijun said excitedly: "Don't talk about other things, let's make the patent arrangement plain and clear and talk about other issues."

This may be one of the few solutions that Lens Semiconductor can offer to compete with the world’s top semiconductor manufacturers. It is surprisingly the FinFET solution, that is, fin field effect transistor, a new cutting-edge complementary metal oxide semiconductor. Transistor.

Patents are required.

Lens Semiconductor can be said to be a leader among domestic semiconductor companies, but it is still a younger brother compared with major international manufacturers. Its weak patent background can be reflected, and there are basically no top patents that can be obtained.

The accumulation is too small.

In the following days, under the leadership of Luo Sheng, whether it is Lens Semiconductor or the Côte d’Azur Laboratory, research scholars went to war. Luo Sheng worked out the process flow diagrams one after another. In order to ensure that nothing went wrong, he went through a few super calculations. Verification, and then the R&D team began to use violent methods to find many strange materials to test one by one.

How else is it called a violent method?

There is no way. Except for those companies that master the technology, no one from the outside world knows it. They can only try violently. Graphene materials are a very good option, and tinene materials are also very good.

However, the current technical conditions cannot be prepared at all, and the cost cannot be lowered. Naturally, it is not currently competitive.

If these materials can be produced, it is no less than a subversive change initiated with new materials, and the fourth industrial revolution may be coming soon.

New materials must be developed. Whether it is graphene or stene, the research and development of these new materials is part of Luo Sheng's future layout, but the meal still needs to be eaten bite by bite.

It is still the era of silicon chips, and the performance of silicon materials has not been fully utilized. At present, the mainstream process is still at the 45-nanometer stage, and the 32-nanometer process is not fully rolled out. Moore's law is still strong.

The R&D team tried hard to make mistakes, and tried out more than a dozen materials almost every day.

...

Technology complex building.

In the supercomputing room on the ground floor of the building, hundreds of engineers are busy here. Most of these people are from Suguang Technology. Luo Sheng is also present.

The focus of recent work is undoubtedly the problem of the chip design and production of the third-generation blue mobile phone, but Luo Sheng will not bury his head in a module 24 hours a day. He has a big business and he has to manage the submarine data center. He is involved in almost every aspect of the core technology.

It's no wonder why Luo Sheng feels that talents are never enough, especially high-end talents.

At this time, a person in charge of Sugon Technology came to Luo Sheng and said with a worried expression: "Mr. Luo, is this really feasible?"

Because Luo Sheng overturned Sugon Technology's solution, it made them very worried. If the computer is destroyed, it will cause trouble.

Luo Sheng was staring at an LCD panel, tapped a few times on the keyboard, brought up a list of data to view, and said without raising his head: "Just do what I said, don't worry about other things, After that, I won’t go to you to fight a lawsuit. This is considered to be broken by myself. Why do you panic after the contract has been signed?"

When the other party heard him say this, it was a moment of silence and didn't say anything.

I can only say that I have money and willfulness. This is a supercomputer, not a civilian PC.

Okay, you have said so, anyway, this is your private supercomputer, you have to go crazy and do not follow Party B’s suggestion, when the computer is broken by you, Sugon Technology will not be back.

In a sense, if Luo Sheng breaks his super-calculation, it will be a good thing for Sugon Technology, because it will definitely cost more money, and Sugon Technology will definitely make a lot of extra money.

Now that Luo Sheng has spoken to this point, the technical person in charge also shut up obediently.

Okay, Party A has the final say!

"Mr. Luo, Mr. Zhang from Huaxin International came to visit, do you want to meet him?" Just as Luo Sheng was arguing about his supercomputing upgrade, the butler of the complex came to him and whispered to inform him.

Luo Sheng nodded: "Well, I see, you first receive it, let him wait, just say I'm dealing with things."

Many people want to see him now, just wait.
