"Zixian, you say, is it possible for Youde to get the opportunity to study abroad?"

"It's hard to say, but I don't think it's unlikely. In just half a year, he picked up the textbooks that he had put down for a year and a half, and his results in the college entrance examination were quite good...... Although it is related to his experience after work, it cannot be denied that he has a strong learning ability. ”

"Hey, let's not talk about him, let's talk about you. Yu Zixian remembered Liu Jian's matter.

"Ah, say me?!"

"Yes, just your major. You used to major in modular electricity, and when you go to study abroad in the future, do you have any plans or plans?"

"Do you mean my future work?"

"No, I'm talking about your choice of major!"

"I am a major in electronics, and my work experience in the past two years has made me more interested in digital integrated circuits, so I want to choose the direction of digital-analog mixed integrated circuits......

“……”

Yu Zixian nodded lightly, but did not speak.

Seeing that Yu Zixian wanted to speak and stopped, Liu Jian asked directly: "Zixian, why is there a problem?"

"To be honest, I have a little idea, maybe a little different from yours!"

"Tell me about it!"

"I completely agree with the general direction you chose, but in the direction of professional subdivision, I have a little other ideas. But before I say that, I want to ask you, how much do you know about our country's integrated circuit industry chain?"

"Industrial chain...... The whole industry chain?"

"Yes, the whole industry chain. At the end of last year, our remote control circuit board production workshop was stuck by Toshiba with the supply of chips, so that the whole factory knew the importance of chips. The various industries involved in the whole process of chip design to application to electronic products can be called the whole industry chain ......"

Yu Zixian gave Liu Jian a detailed explanation of the industries involved in the integrated circuit industry chain.

"In fact, although our country is backward in the manufacturing and packaging and testing of integrated circuits, it has begun to lay out a basically complete layout in these industries...... However, there is a blank in the chip design, software, EDA and semiconductor materials industries in the upstream of the integrated circuit industry......"

"I'll tell you about this chip design software EDA ...... first."

EDA, short for Electronics Design Automation. Generally speaking, EDA design tools are in the form of a set of computer software, so we usually refer to "EDA tools" or "EDA software" as "mixed words".

The EDA software system is very large, and the simplest system includes two fields: electronic circuit design and electronic circuit simulation. In the electronic information industry, EDA tools are indispensable for the design of integrated circuits and PCBs (printed circuit boards).

It can be said that EDA software is the cutting-edge of industrial software, representing the real R&D and innovation of a country.

Although the scale of the EDA tool industry is not large, it seems to be not worth mentioning compared to the hundreds of billions of dollars in the integrated circuit industry. However, the EDA industry is the most upstream of the electronic design industry, and it is also one of the cornerstones of the entire electronic information industry. This is especially true for the integrated circuit industry. If an integrated circuit company does not use EDA tools, it will not be able to do anything at all.

In this software field, the Republic of China is extremely dependent on Western countries, whether it is now in 91 years, or more than 20 years later, whether it is today's Xiangji wants to design and optimize a chip by itself, or Hua Wei wants to engage in various chips based on ARM for more than 20 years, it is absolutely impossible to design chips without EDA software in Western countries, or launch other products.

More than two decades later, the EDA industry is a very clear oligopoly structure. The three largest EDA vendors, Synopsys, Cadence and Mentor Graphics, have more than 60% market share in the IC design space. All three of these software are in the United States, of which Mentor was acquired by Siemens, but Mentor's headquarters is still in the United States, and it is still American software.

In the Republic market, 95% of EDA sales are split between the above three companies, and the remaining 5% is partly occupied by other foreign companies such as Ansys. Therefore, if these three major manufacturers shut down the supply of tools to an integrated circuit manufacturer, it is no different from directly "strrangling" this manufacturer.

"Liu Jian, no matter how much money we invest in the field of integrated circuits, how many wafer factories and packaging factories we build, and how many integrated circuit design enterprises, equipment enterprises, and material enterprises are supported, our necks are still grabbed by the Americans. The key EDA industry here is firmly controlled by the Americans. ”

However, Yu Zixian understands in his heart that whether it is now or later, the neck of the American EDA card does not seem to be able to completely blame the lack of vision or lack of effort of the domestic industry.

In fact, five years ago in 1986, when the country launched the Wuxi microelectronics project, it was already organizing the research and development of an aided design system for integrated circuits - the "Panda System", and it was basically launched simultaneously with the three major foreign factories, but then the domestic EDA industry did not develop.

On the one hand, it is dragged down by the overall development level of the domestic integrated circuit industry, resulting in a lack of demand for products and the supply of talents; on the other hand, it is attributed to the poor atmosphere of domestic hard science and technology entrepreneurship, the policy environment for R&D personnel in scientific research institutes to start a business is not open enough, and the support of capital is also insufficient.

Yu Zixian was silent for a long time, he could only sigh, looked at Liu Jian half-lying on the bed and looked at himself silently, so he had to continue: "This is the situation of EDA, and there is the semiconductor material industry......"

Semiconductor manufacturing materials mainly include silicon wafers, electronic gases, photomasks, photoresist supporting chemicals, polishing materials, photoresists, wet chemicals and sputtering targets.

Compared with the semiconductor equipment market, which is also the upstream of the industrial chain, the semiconductor material market is more segmented, and the market space for a single product is very small, so there are few pure semiconductor material companies.

Semiconductor materials tend to be just a small part of the business of some large materials manufacturers, such as The DOW Chemical Company, DuPont, Mitsubishi Chemical, Sumitomo Chemical, etc., and the semiconductor materials business is just a branch of their electronic materials division.

Despite this, due to the stringent material requirements of the semiconductor process, only a few suppliers can supply products for a single semiconductor chemical. In China, only 3 to 5 microns of process materials can be supplied, in the 1 micron and below level is still blank!

Taking the semiconductor wafer market as an example, the global semiconductor wafer market is highly concentrated, and the products are mainly concentrated in Japan, South Korea, Germany and Republic Bay Island and other developed semiconductor countries and regions, and the production scale of domestic mainland manufacturers is generally small.

The semiconductor materials used by Kamsgene are completely dependent on Marubeni Co., Ltd.'s imports from Saymoto!

"Liu Jian, I said so much about the industrial chain of integrated circuit design, EDA software and semiconductor supply materials, just to explain to you that in terms of these two industries, Xiangji is facing the grim situation faced by the Republic. And this is also a question that the Republic must face and think about!"

In terms of EDA, it is impossible to make a breakthrough alone, but in the semiconductor materials industry, because of the variety of materials, it seems that it is not possible to do it alone.

Yu Zixian was worried before, how to choose, whether to let Liu Jian choose in these two directions!

At this time, in terms of domestic EDA, there is already a "Panda System" project, but it has not been developed in the future, but fortunately, there is already this project!

However, in terms of the supply of semiconductor materials, many subdivisions seem to be really blank in China!

Is it necessary to contact Minister Li Jincheng and Minister Li in the future?

Twenty years later, the form is very severe, ASML's most advanced lithography machine, Chongxin International has signed an order contract, paid the money, queued up for a long time, just arrived at the supply, said to stop supply!

These are real experiences and lessons!

Even if it is an eye-catcher, we must fire this first shot! Let Liu Jian be a pioneer now.

"Liu Jian, why don't you choose to specialize in photoresist materials...... But then you'll have to start all over again with materials and chemistry......"

Although photoresist is used in semiconductor manufacturing, the preparation of photoresist needs to start from the material and chemistry.

Yu Zixian quickly cut through the mess, and made a decision in his heart, photolithography is the most important and critical process in chip production, and photoresist is the most basic and critical consumables;

Since the current energy and manpower are limited, choose the most critical direction to break through...... Just the year after tomorrow, Ruihong Electronics will be officially established, and Yu Zixian also wants to get involved, if Liu Jian graduates by then, he can join in immediately!

"Zixian, I heard it in a daze, are you sure you want me to choose the direction of this photoresist?

"Uh-uh...... I said slut, since I was a child, have I lied to you?"

"Doesn't seem to be. ”

"Have I ever tricked you?"

"Nope. ”

"Then are you as handsome as I am?"

"No...... Salted fish, what kind of routine are you?!Does choosing a major have anything to do with being handsome?"

"Yes, you just said it, you're not as handsome as me, so you have to listen to me!"

"Stinky salted fish, what kind of logic are you?!"

"Didn't you quarrel before, what kind of blood and backbone of military workers, forced me to stay, and then I stayed......"

"Hahaha, slut, now is also the time to reflect the enthusiasm of your military workers......"

"I said salted fish, is it really that serious?"

"Hmm. I'm telling you that,"

"Alright then!"

"That's right. Yu Zixian finally grinned.

"Salted fish, I still feel like I've been cheated by you......"

"Oh, go to sleep, it's twelve o'clock at night...... Anyway, you agreed, but you don't regret it! Don't think about the rest of the things, go to work tomorrow!"

Although Yu Zixian knew that it was definitely wrong to force the burden on Liu Jian in this way, it was too difficult for semiconductor materials to really develop in the later stage!

Liu Jian is a seed of semiconductor materials, he not only went to learn technology, but also to make friends and break into the semiconductor material production enterprises...... Otherwise, I don't even know anyone, how to dig the foot of the wall in the future?

The next day, Yu Zixian sent Liu Jian back to Sifang Electronics early. After Liu Jian got out of the car, Yu Zixian rolled down the window and waved goodbye.

Through the gate of the factory, looking at the Soviet-style office building with a sense of age, Yu Zixian couldn't help but think: "I don't know what Old Man Luo is doing at this time?"

Yu Zixian's first reaction was to "touch porcelain", and he was about to shout two sentences: "Old comrade, find a good place to touch porcelain, I'm not fragrant!"

But when I think about it, no, the old people in this era are still very simple.

It's not like the bad people are getting old and the old people are getting bad in the 10s of the 21st century!

Yu Zixian rolled down the window of the car, just about to ask a few words, but he didn't want to, the old man in front of the car pushed the cap up, and looked at himself with a smile!

When did Old Man Luo become so fashionable?

Yu Zixian hurriedly rolled up the window and pretended to be dead. I originally thought that no one knew the Rubik's Cube wisdom car that I drove, and it would definitely be nothing to do if I came for a walk, but I didn't expect that this happened to meet Old Man Luo!

Within a few seconds, Yu Zixian, who was pretending to be dead, heard the sound of "bang-bang" knocking on the glass.

Yu Zixian is still pretending to be dead, pretending to be dead!

"Hey, little rabbit, you play dead for me, believe it or not, I'll call the machinery now, tow your car to the workshop, and unload eight large pieces in person?"

Just now he said that the old man is not broken, and at this moment, Yu Zixian wants to take it back.

Slowly rolled down the window, and half of it was shaken, and asked vigilantly: "I said Director Luo, what are you expensive and expensive?"

"It's okay, I just want to chat with you and talk about your shares! It's almost the end of the year, and the remote control circuit board factory is about to pay dividends this year, if you don't want to pay dividends, then forget it, I'll keep it for you for the time being! I roughly calculated, how can there be two or three million...... Okay, I'm going to work right away, I'm leaving. ”

After saying that, the old man smiled, turned around and left, but after taking two steps, he turned back and said, "But I know that you are a rich man now, and you will definitely not look at such a little money." ”

Yu Zixian smiled, looked at the left and right rearview mirrors, and then ignited, stepped on the clutch, hung up the reverse gear, and did it in one go, and at the same time as Luo Shouwu finished speaking, the car had already flown backwards.

Only Luo Shouwu pointed at Yu Zixian's ass and scolded: "I...... Yu Zixian, you little cub, you are really promising!" After finishing speaking, he shook his head angrily and walked towards the factory office building!

Luo Shouwu didn't walk more than ten meters, but he heard the sound of a car "honking" behind him.

"Uncle Luo, come up, I'll pull you!" Yu Zixian stretched out his head and said to Luo Shouwu.

However, Luo Shouwu ignored it and walked directly to the office building.

"I'll go, Lao Luo won't be really angry, right?"

Yu Zixian hurriedly drove the car in, parked in the parking lot on the side of the office building, got out of the car and trotted all the way, and finally caught up with Luo Shouwu before he entered the office building.

"Uncle Luo, I was wrong...... Yu Zixian didn't finish speaking, but he was grabbed by Luo Shouwu: "Hmph, little rabbit, don't run this time!"

I just saw Director Kong come in and greeted, "Just right, come to Director Kong, press him to my office for me......"

"I'm ...... Old man Luo, you really know how to play!" Yu Zixian was stunned for a moment.
