"How to build more transistors in a limited area is not only the direction of CPU design, but also the direction of memory, which goes without saying. Let's focus on the structure of MOSFETs. ”

When it came to the technical discussions, there were a few more people in the room. Su Yuanshan grabbed the manuscript paper and drew a structure diagram of a MOSFET like graffiti.

"Wait, I need to say. Li Mingliu interrupted Su Yuanshan's words: "Mr. Shan, don't say it nicely. We all know that a building on a piece of land can hold more rooms than a bungalow. However, chip design is not architectural design, and architectural design only needs to consider structural mechanics and material mechanics. As long as you don't build oddly shaped, construction is generally fine. ”

"The difficulty in chip design lies in the implementation of the process, and I can now draw a multi-layer structure right away. But to carve it out, that's the hard part. ”

Su Yuanshan was happy when he heard it: "This kind of process matter will be handed over to the wafer factory." ”

Li Mingliu obviously didn't believe it: "It's really that simple? I think the wafer factory will beat people." ”

"Well, it's not that simple. Su Yuanshan put down his pen with a smile and looked at the people in the office.

These are the top people of this era, and they have been in related industries for so long, and you want to say that they can't think of developing the structure to multiple layers, which is really funny. However, as Li Mingliu said, the structure from a single storey to a multi-storey, "from a bungalow to a building", involves not only design, but also craftsmanship.

It's like building a house and building a bungalow, you can do it by shouting three or five or two masons at will. But to build a skyscraper, you don't have a professional construction management team, you don't have solutions to all kinds of problems, even shouting that 10,000 masons can't repair it.

To create a new architecture, it is necessary to create new processes to match the implementation.

From channel to collapse, to P, N doping, etch cleaning, ion implantation, oxidative evaporation, vapor precipitation...... The whole process is down, to say the least, there are dozens of steps.

With this set of processes, the technology may not need to be innovated, but the steps need to be redesigned. Not to mention, there are also long-standing problems such as cell cell leakage and poor adhesion of gate polysilicon.

Playing engineering is not like playing with materials, just the emperor. New processes can only be piled up by money, time and loneliness.

......

After a few seconds of silence, Su Yuanshan said slowly.

"Design and craftsmanship are like two legs. Whether it's the birth of a new architecture or a breakthrough in the manufacturing process. will drive the entire industry forward. ”

Su Yuanshan pursed his lips and carefully considered the language: "But from the emergence of large-scale integrated circuits to the present, the development of semiconductors is mainly enjoying the dividends brought by process breakthroughs. Let's look at the process nodes and calculate the number of transistors. ”

"But there is a limit to the process, and the breakthrough in the process will definitely become difficult in the foreseeable future. At that time, the improvement of the structure was the only way to save Moore's Law. ”

Su Yuanshan's memory flashed in front of his eyes, and it was when the light source of the lithography machine stopped at DUV193nm that the idea of FINFET (fin field-effect transistor) appeared, the idea of GAA (fence structure) also appeared, and at the same time, a more radical EUV scheme also appeared.

"Now we are not only behind in the manufacturing process, but also in terms of architecture...... So, how will you fight with others in the future?"

Su Yuanshan said and looked at everyone: "You don't want to rely on VCD all the time and rely on selling business divisions to raise you, right?"

This sentence caused an indescribable emotion to rise in everyone.

Far Chip's main sources of revenue were previously two, one was EDA and the other was VCD.

Then Su Yuanshan sold 20% of Xinghai's shares to acquire Cyrix, and took back the money to build Yuanxin Science and Technology Park. Then he sold more than half of his EDA shares, brought back more than 2 billion US dollars in cash, opened the Shanghai Science and Technology Park and V-SOL International, and also built a Silicon Valley R&D center.

As for microcontrollers, YXCPU, architecture licensing, and various commercial chips...... It's actually a small amount of money.

Especially for single-chip microcomputers, in order to forcibly push the 91 single-chip microcomputer, the licensing price of Yuanxin's single-chip microcomputer is very low. Although it successfully entered the European market, it only made enough money to cover expenses.

Therefore, in just two years, Yuanxin has successfully made the single-chip microcomputer the price of cabbage. The cost of many domestic electronic products, from TV remote control boards to radios and cassette recorders, has been reduced by dozens of dollars.

To this end, Science and Technology Daily also published a special column to unabashedly praise Yuanxin, which can be regarded as a political gain.

As a result, the current salaries of Yuanxin's employees almost all depend on the VCD division - last year, Yuanxin even had more than 10,000 people in the factory and R&D center, and the salary of more than 500 million yuan came from the contribution of the VCD division.

Even if Li Mingliu has been hailed as the father of VCD by the outside world, he has to admit that VCD ...... It's really not very technical.

It is really ...... for a high-tech enterprise to rely on a "low-end" electronic product with little technical content to feed

It's humiliating.

......

After the meeting ended, Su Yuanshan stuffed the scratch paper on the table full of his thoughts into the shredder.

"I've been staying here for the past few days, and I'm going to sort out my thoughts with you and finally determine the direction. The direction is determined, let's bow our heads and stumble. ”

Saying that, Su Yuanshan looked at Jiang Tao again: "Senior Brother Jiang, the controller involves a lot of technology and is very complex, but as long as you understand it, it is not a problem to design any chip." ”

Jiang Tao nodded: "If you follow the direction you said, I am thinking, the processor of the main control chip may have to use a special processor like the YX architecture to be sufficient." ”

Su Yuanshan said: "Well, that's the inevitable direction. Large-scale data throughput requires high-speed processors. But now, the microcontroller is barely enough. ”

After dinner, Su Yuanshan returned to the hotel.

Originally, Jiang Tao planned to borrow him a laptop, but even a foreign-related international hotel like Hilton did not open the network at this time, so he had to give up.

"Nothing to do today, right?" Su Yuanshan saw Zhou Xiaohui take out his mobile phone from his briefcase - when there was a technical seminar this afternoon, Zhou Xiaohui left the conference room with his mobile phone, so as not to disturb them.

"It's not a big deal, it's just that the special zone said that the e-mail office has completed the internal test. ”

"Oh?" Su Yuanshan became interested, sat up straight and said, "What did Senior Brother Ding say over there?"

"I said that I planned to go to the science and technology park tomorrow and use Yuanxin's server to set up an internal mail server, so that everyone could help test it. If that's fine, it's ready to go to market. Zhou Xiaohui paused and said, "I'll ask him to contact Mr. Xi directly." ”

"Hmm. Su Yuanshan nodded, and suddenly remembered a funny thing, and asked, "Did he name the e-mail system?"

"It's said to be called 163. Zhou Xiaohui blinked and said: "Lao Ding said that he inquired for a long time before he found out, and the civilian dial-up network account being set up by the General Administration of Telecommunications is 163, and he plans to rub his mother." ”

Zhou Xiaohui spread his hands: "He said the truth." ”

"Hahahaha!"

Su Yuanshan laughed as he picked up the buzzing phone.
