Chapter 329： [Explain the patent arrangements clearly]

Just now a group of scholars exchanged their academic knowledge. Everyone spoke freely and almost ignored Luo Sheng.

At this time, I came back to realize that Luo Sheng is not only an entrepreneur who is proficient in business, but also has a larger hidden attribute, that is, a technology big coffee.

Luo Sheng apparently didn't finish. He stared at the revised mathematical model and continued: "One more thing, since all of them take the depleted layer of silicon and insert an oxide layer, then why have to put a bunch of useless? Is silicon underneath? Wouldn't it be nicer to have another gate directly under the oxide layer with the channel sandwiched on both sides? "

Everyone stumbled for a while. After returning to God, they all made a case and Luo Sheng added: "This is not enough. In this case, what else is necessary to bury the oxide layer in the silicon? I can completely make the silicon out. Isn't it cool to wrap the insulation layer like a sandwich and put a grid on the outside? "

A semiconductor research scholar said with great excitement: "It's a genius-like idea. Such a solution not only greatly reduces the leakage current, but because there is another gate, these two gates are generally connected together. Therefore, it is equivalent to greatly increasing the capacitance of the insulating layer mentioned earlier, which greatly improves the switching performance of the transistor. I dare to make a decision. This tri-gate transistor is definitely a revolutionary improvement in architecture. Not only 45 nanometers, but also 32 nanometers, 22 nanometers, and 14 nanometers have great imagination, which is another victory for 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 emerged at the historic moment, which is how many nanometers the next generation chip.

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 an equidistant series with a ratio of about 0.7, which is why .

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

At this moment, a group of research scholars present are very excited, but some people have returned to reason after the excitement.

A scholar tactically supported the mirror and said, "This is a genius design. Basically, I don't need to use supercomputer simulation to verify that I dare to judge that it is feasible, but it is difficult to realize this idea. Why? Because the part that stands up Silicon, which is used as a channel, is too thin, with less than 10 nanometers. It is not only far smaller than the minimum size of the transistor (currently), but also far smaller than the smallest size that can be carved by the most sophisticated lithography machines today. How to get this plan out is the real problem. "

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

Yeah, this problem cannot be avoided, and in the end it came back to the difficult problem of lithography machines. At present, the most precise lithography machines are uncertain. Besides, it is impossible for China to buy the most advanced lithography machines. Lithography machine equipment.

At present, Huaxin International is the domestic leader in this field, but it is frustrating that foreigners have been able to mass-produce 32-nanometer process chips, and Huaxin International now does not even produce 65-nanometer chips, which is still being introduced. In the case of a lithography machine, it is impossible to make a lithography machine of 65 nanometers process.

Luo Sheng laughed: "Everyone understands it wrong, and it takes a lot of process flow diagrams to explain it in detail, but the basic principle is that this part of silicon is not lithographic, but grown out. It is first etched with ordinary precision lithography. Make 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 away the excess material, and the rest is these standing It ’s so thin, it ’s so simple. "

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

I knelt down completely, this IQ is too crushing.

Seeing that everyone was speechless, Luo Sheng could not help but add a smile: "Actually, the physical model of this tri-gate and ring-gate transistor can be traced back to around 2000. Professor Hu Zhengming of Berkeley, this is the first he proposed. , But so far no one has achieved it, but this solution can be achieved. "

Xu Zhijun said exhilaratingly, "He said other things, and made the patent arrangements clear and clear on other issues."

This may be one of the few solutions that Lansi Semiconductor can compete with the world's top semiconductor manufacturers. It is a FinFET solution, which is a fin field-effect transistor, a new leading-edge complementary metal-oxide semiconductor. Transistor.

Patents are required.

Lance Semiconductors can be said to be a leader among domestic semiconductor companies, but it is still a younger brother than international manufacturers. Weak patents can be reflected, and there are basically no top patents.

I have accumulated too little.

In the following days, under the leadership of Luo Sheng, whether it was Lansi Semiconductor or the French Riviera Laboratory, research scholars went to war. Luo Sheng worked out the process flow chart one after another. Verification, and then the R & D team began to use violent methods to find many strange materials and test them one by one.

How else would it be called a violent method.

There is no way. Except for those companies that have mastered the technology, no one outside knows it. They can only try violently. Graphene materials are very good choices, and tinene materials are also very good.

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

If these materials can be produced, no less than a subversive change initiated with new materials, the fourth industrial revolution may come sooner.

The development of new materials is definitely necessary. Whether it is graphene or tinene, the research and development of these new materials are part of Luo Sheng's future layout, but the food still needs to be eaten bite by bite.

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

The R & D team worked **** trial and error, and tried and produced results on almost a dozen materials every day.

Uh ...

Science and technology complex building.

Hundreds of engineers are busy here in the supercomputing room on the ground floor of the building. Most of these people are from Shuguang Technology, and Luo Sheng is also present.

The focus of recent work is undoubtedly the problem of the chip design and production of the third-generation Azure mobile phone, but Luo Sheng will not bury himself in a module 24 hours a day, and his family is a big business. He also has to manage the submarine data center. He has almost all of his core technologies in all aspects.

It is no wonder why Luo Sheng feels that talent is never enough, especially high-end talent.

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

Because Luo Sheng overthrew the solution of Dawning Technology ~ www.novelhall.com ~ this made them very worried, in case the computer goes down, it will cause trouble.

Luo Sheng was staring at a liquid crystal display panel, tapped on the keyboard a few times, and brought up a list of data to view. He said without raising his head, "Just do what I say, you do n’t need to worry about it, it ’s bad. I won't come to you for a lawsuit. It's my fault. The contract has been signed. What are you worried about? "

When the other party heard him say this, it was a lingering speech and said nothing.

I can only say that I am rich and willful. This is a supercomputer, not a civilian PC.

Lime, you said so. Anyway, this is your personal supercomputer. You have to be blind and don't follow Party B's suggestion. When the computer is damaged by you, Shuguang Technology will not back it up.

In a sense, if Luo Sheng broke his supercomputing, it would be a good thing for Shuguang Technology, because it would definitely cost more money, then Shuguang Technology would definitely make a lot of extra money.

Since Luo Sheng has all said this, the person in charge of technology also shut up obediently.

Lime, Party A has the last chance!

"Mr. Luo, President Zhang of Huaxin International came to visit, would you like to meet him?" Just as Luo Sheng was troubled by his supercomputing upgrade, the housekeeper of the complex came to him and whispered to inform him.

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

I now have more people who want to see him, wait.

Uh ...
