How does science and technology develop? How do scientists generally play?

In the eyes of ordinary people, it is a very lofty thing.

In Wang Anran's view, it's all nonsense.

The development of science depends on the fantasies, oh, conjectures of scientists.

To sum up the eight words, it is "bold guessing, careful verification." ”

Of course, this guess is not a blind guess, but is based on a certain theoretical foundation and scientific method.

The next day, Professor Hu opened the email sent by Zhang Dajing, and when he read the title, he almost vomited three liters of blood.

"How is it possible, this is my idea!"

Analysis of applied voltage, passing current, loop voltage change curve, leakage curve.

Professor Hu's first impression was, "This is a technical article with detailed data and good analysis. ”

And seeing the final conclusion, Professor Hu was dumbfounded, the BISM mathematical model, about voltage, leakage, electron pass rate, a complete set of mathematical formulas, and even deduced the service life of the transistor.

"What I used to do was the path that others had taken. ”

Professor Hu stared at the author, the first author, Ji Xiaoqing.

He suddenly had a feeling of being born and bright, and the whole person collapsed on the chair in a languid.

Vaguely, I heard the phone ringing, and outside the study, Mrs. Hu said: "Old Hu, your phone call, Mr. Zhang Dajing and Mr. Zhang called from China." ”

"Let's get the study!"

......

"Old Hu, how is it, this paper?"

These words fell on Professor Hu's ears, which was particularly harsh.

"Still looking, the technical data still needs to be verified. ”

"Okay, let me know when you have the result, I am also entrusted by someone. ”

Professor Hu was silent for a while.

"Lao Hu, thank you, next time I go to the United States, I am thanking you alone. ”

“......”

"Old Hu, are you there, can you hear me?"

“......”

"Lao Hu, long-distance is very expensive, otherwise, let's leave it like this first. ”

Zhang Dajing was about to hang up the phone with a confused face, and Professor Hu's voice came from the microphone.

"Dajing, who is this Ji Xiaoqing?"

Zhang Dajing hurriedly put the microphone to his ear, and he was happy, since Hu Zhengming was interested in this Ji Xiaoqing, it was certain that the quality of this paper was still there, as for whether it could be on the front line of the journal, he didn't dare to guarantee this.

"I'm not very familiar with this Ji Xiaoqing, I know that she is a technician of Huaxin Technology, their boss, maybe you have heard of it, Mr. Wang Anran. ”

"Athlon CPU, ripper graphics card, that Wang Anran of Huaxin Technology?"

"Well, that's him!"

Professor Hu sighed and said, "The mainland, Huaxin Technology, has this strength. ”

Hu Zhengming is well aware that it is impossible to carry out research on the BISM mathematical model of the new FinFET transistor without sufficient financial resources.

I have just received a grant from IBM to start the actual verification experiment.

In fact, FinFET fishfin transistors mainly solve the technical difficulties of trench leakage, but under the current 500nm manufacturing process, because of sufficient spacing, transistor trench leakage is almost negligible.

This is also the main reason why the major chip giants are not interested in the new FinFET transistors.

In their view, the limited energy, financial resources, and R&D resources should be invested in how to improve the manufacturing process rather than investing in the new FinFET transistors that cannot be seen.

Not to mention, even if FinFET transistors are developed, they still have a long way to go in commercial use.

The existing production process needs to be greatly renovated.

Therefore, it is not that chip giants such as Intel, IBM, and Texas Instruments cannot develop new FinFET transistors.

It's just that everyone hasn't paid enough attention to this.

And not many people believe that FinFET is the way of the future.

This is also the reason why Professor Hu has not been able to attract sponsorship everywhere.

Wang Anran dared to be the first to eat crabs, and even walked in the forefront of the world in the commercialization research of FinFET.

More than 200 million US dollars have been invested before and after, and the follow-up commercialization will continue to be invested, equivalent to nearly 2 billion yuan.

There is no way, courage is costly.

This is naturally also the strength of Huaxin Technology's hard waist.

After listening to the introduction, Su Lao's eyes opened wider than a light bulb, and he turned his head to stare at Wang Anran.

"Anran, a mathematical model, you spent 2 billion?"

Chen Chuangjia shook his head, even if he has a good sense of Huaxin Technology now, he refuses to accept this reality in his heart.

2 billion, what is the concept, the annual allocation of the Institute of Physics and Chemistry is less than 30 million, and it is also responsible for the food and drink of hundreds of people.

"Su Lao, FinFET new transistor, in the actual chip processing, the need for masks is 40% more than the ordinary process, reaching more than 30 pieces, the manufacturing process process is increased by 60%, reaching nearly 300 processes, in order to improve the experimental accuracy, completely manual adjustment, in the 320 nm manufacturing process, we successfully manufactured samples. ”

The normal process requires a mask that costs $500,000 a time, while the FinFET manufacturing process costs $800,000.

In chip mass production, the cost of the mask is spread over each chip, which is negligible.

But in tape-out production, the cost is high.

"What are the advantages of this new FinFET transistor?"

"Transistors are oxides, silicon semiconductor materials, metal layers, and the trench spacing is too close, and the new FinFET transistors can significantly reduce leakage by reducing the connection width, and will perform very well in the future nano manufacturing process." ”

Su Lao flipped through the technical documents, pointed to one of the paragraphs, and said to Wang Anran: "Under the 320nm manufacturing process, the leakage of your FinFET transistors is only 2% less than that of ordinary transistors.

In practical application, for this 2%, more than 80 processes are added, the cost is significantly increased, and the yield rate is significantly reduced.

Wang Anran shook his head, it seems that even Su Lao is inevitably showing off his old qualifications, pointing out the country, and interrogating the world.

"Old Su, please flip it down!"

"Below?"

Su Lao looked at Wang Anran, turned a few more pages, and the next text made him completely feel the magic of the new FinFET transistor.

The 90nm manufacturing process can reduce the leakage rate by 17%.

The 45nm manufacturing process can reduce the leakage rate by 32%.

The 32nm manufacturing process can reduce the leakage rate by 57%.

The 22nm manufacturing process can reduce the leakage rate by 72%.

14nm ...... 7nm ...... 5nm ......

Su Lao pointed to the data, looked at Wang Anran and asked, "This, this, is the data accurate?"

Wang Anran waved his hand, pointed at Ji Xiaoqing, and said: "This is for Director Ji, it is completely the data predicted by the BISM mathematical model, I think, she has the most right to speak!"
