The car drove into Zhangjiang High-tech Zone.

At this time, Zhangjiang was far from being as prosperous as in later generations, and there were still large areas of the countryside hidden among the shade of bamboo trees, but the wide cement pavement announced the future of the place.

At the entrance of the factory, the four gilded characters of "V-SOL International" shone brightly - the Chinese name of the joint venture factory was taken one word each in Yuanxin and Deyi.

Zhang Rujin led Shengguang Peak, the Italian Alzide, and Chen Jianguo, who came to enclose the land, to greet him.

Since Chen Jianguo returned to Yuanxin to start the copper process, he has been going to several laboratories across the country that can engage in chemical vapor precipitation, and he also followed Professor Su Xinghe to go abroad for a walk. In his words, it is to sharpen the knife and not cut the wood, first understand the theory before talking.

However, the process technology still has to fall on the experiment after all, although Yuanxin also has an assembled chip line, but due to the backwardness of equipment and technology, it can only be an expedient measure.

Now that the wafer factory has landed here, Chen Jianguo will of course move the laboratory here.

"Dr. Zhang. As soon as Su Yuanshan got out of the car, he strode forward, held Zhang Rujin's hand and said sincerely: "It's hard work." ”

"It's not hard. Zhang Rujin was half a head shorter than Su Yuanshan, and when he looked at Su Yuanshan's young face, he could naturally feel the heartfelt respect that this young man had for him - this actually bothered him for a long time.

Later, it wasn't until he came to Shanghai that he came into contact with the employees of Yuanxin, and then participated in the annual meeting, and became familiar with Li Mingliu, Jiang Tao and other high-level executives, that he knew more about Su Yuanshan.

Of course, with Chen Jianguo, Su Yuanshan's personal brother, coming over, his understanding of Su Yuanshan can be regarded as truly three-dimensional.

I probably guessed why Su Yuanshan would "respect" himself extraordinarily.

After shaking hands with the others one by one and introducing each other, Zhang Rujin took the lead in taking a step forward: "Let's go, let's go see the mask factory." ”

Reticle, also known as photomask, is called Mask in English. It is a master made of quartz and can be used in the semiconductor exposure process. From the perspective of the chip production process, it belongs to the preliminary process.

And this process of converting the pattern from the reticle master to the wafer is like working with a money printing machine.

We can think of the lithography machine as a money printing machine, the process of printing the pattern of the banknote master onto the paper, just like the lithography machine printing the chip pattern on the wafer, all need to have a master, and this master is a mask in semiconductor manufacturing.

In order to manufacture a chip, hundreds of processes are required, and there is more than one mask, and in principle, the higher the process accuracy, the more masks are needed.

For example, in later generations, about 60 masks were required for the 14nm process, and 80 masks or more for 7nm.

Of course, the quality requirements of the mask are also different, for some processes that require high precision, the corresponding mask has the highest requirements for accuracy, such as transistor-related masks, while the process with less high requirements for accuracy, such as Pad (punching holes), etc., has lower requirements, and the price of the mask is cheaper.

Advanced manufacturing processes require more and more mask accuracy and no defects, so post-reticle inspection is also important.

(Note: The above explanation of the mask is an excerpt from Zhihu's answer by Han Ming, BD Director of Quanxin Intelligent Manufacturing Technology Co., Ltd., and I would like to thank you here - I didn't organize the language and processing myself because he said it too clearly...... ）

Because of the complexity of the reticle production process and the higher the accuracy of the process, the longer it will take, it is not a must-have workshop for a fab – because the fab can outsource the mask production to other reticle fabs, and it can also manufacture the reticles required by other industries.

The reason why he chose to build a mask factory for the first time was that Zhang Rujin also saw this.

At present, there is no professional OEM mask factory in China, Zhang Rujin can directly bring Deyi's mask technology over, and he can make a little money after it is built.

- Of course, he didn't know that Su Yuanshan actually planned to lose two billion US dollars in the wafer factory.

"Almost all of the main equipment of the mask factory is in the hands of Niguo, including the core mask writer. Fortunately, there was no big trouble in the purchase process, and the Niguo Nuflare company said that it had started packing and would be able to ship it immediately. ”

Zhang Rujin led the group along the brand-new cement pavement to the workshop in the distance, walking all the way, introducing the situation all the way.

Su Yuanshan glanced up, and saw that the entire science and technology park was like a rapidly emerging city, and countless construction sites were busy.

"After calculation, it will take half a year at most for the mask factory to be put into operation. ”

"Well, when the time comes, we will go and run the business, and simply let Huajing withdraw the mask factory. Su Yuanshan joked: "In the process of tape-out, the production cost of the mask is too high, and Huajing technology is not good, and the cost is even higher." ”

"It's mostly technology. Zhang Rujin smiled and turned to Chen Jianguo at the same time: "Dr. Chen, I heard that you have a patent for a mask version?"

Chen Jianguo nodded a little embarrassedly: "When UMC and them jointly made the mask, I was a little inspired. It's not a big breakthrough. ”

"Hehe, a little progress is good. Even if a patent is enough to reduce the cost of a wafer by one dollar, it is also an increase in competitiveness. ”

"That's it. Su Yuanshan took over the words for his senior brother, he knew that his senior brother was not good at words, and said with a smile: "Especially the cost of time, in the field of semiconductors, time is a big cost." ”

After visiting the factory, it was close to six o'clock, perhaps because he had heard from the employees of Yuanxin that Su Yuanshan had always eaten staff meals, so Zhang Rujin did not make any other arrangements, but directly invited Su Yuanshan to a meal in the factory canteen.

However, he was embarrassed to invite everyone to eat an iron plate box lunch, so he set up a table, but the dish was still a big pot dish.

Well...... Of course, Su Yuanshan is not picky, but he is not very used to the food here.

After dinner, Zhang Rujin sent Su Yuanshan and others out of the park, and set a meeting with Su Yuanshan in his office at ten o'clock tomorrow morning.

......

Li Mingliu sent Su Yuanshan and Zhou Xiaohui to the door of the hotel, he didn't even bother to get out of the car, he rolled down the window directly, and said to Su Yuanshan: "I won't come tomorrow, I'll arrange a car for you to wait for you here at half past eight." ”

"Well, go ahead. I'll be in the factory for a day tomorrow and I'll be there the day after tomorrow. ”

“OK~！”

The two stood at the door of the hotel, watched Li Mingliu start slowly, and then plunged into the street with one foot of the accelerator.

Zhou Xiaohui blinked: "He drove so fast?"

"It should be far from drag racing - if he dares to drag racing, he has to clean up. Su Yuanshan smiled as he spoke: "But he broke Santana, and the throttle couldn't soar in the end." ”

“...... What about last year's new car! I think he's very well maintained. ”

“...... I'm talking about performance. ”

The two dragged their suitcases to the front desk to check in, he lived in the suite as always, and then opened a standard room opposite Zhou Xiaohui.

After returning to the room, Zhou Xiaohui put away the luggage, held the folder, held the mobile phone and battery, and came to the living room on Su Yuanshan's side.

The two of them sat on the sofa, using the coffee table as a desk, and began to deal with the calls they received today and the affairs they had arranged.

......

An hour later, Su Yuanshan hung up Gao Xiaodi's phone and took a long breath.

"A little irritable, originally Senior Brother Xi should be in charge of scientific research, but he turned out to be like an old lady...... Everything is piled up on me. ”

Su Yuanshan stretched his waist and was very depressed: "I'm so busy on business trips." ”

Zhou Xiaohui stood up and straightened her skirt - Su Yuanshan asked her to dress casually, but she said that she looked like a secretary when she wore a formal dress...... Wen Yan smiled: "You are reluctant to squeeze him." ”

"It's not that I'm reluctant...... Well, there is a specialization in the art industry. He may not be as good at this as I am, so he concentrates on being his mascot. ”

What Su Yuanshan said is really true, there are so many groups in Yuanxin Science and Technology Park, if you have to find someone who knows a little bit about everything, it really has to be Su Yuanshan.

And Xi Xiaoding, let him engage in mathematical software, deep learning, and artificial intelligence......

Anyway, these are the future directions, and his group of math workers can only be best worth the money when they are engaged in these.

Not long after Su Yuanshan's mobile phone was put down, it rang again, and after Su Yuanshan connected it, he heard his father's voice ringing.

"Xiaoshan, are you done?"

"It's okay, what's the matter, Dad. Su Yuanshan changed his lazy posture, he knew that the supercomputer motherboard had reached a critical period recently, and he would definitely not let himself help if he looked for himself - this thing Su Yuanshan really wouldn't, even if his father asked him to help, he could only stare dryly.

"It's nothing, it's just to tell you that the technical papers on the 91 series of microcontrollers have passed the ISSCC and will be published at the end of the month. ”

"Really!" Su Yuanshan jumped up: "Congratulations, Dad!"

"Hehe, isn't it just a paper. ”

On the phone, Professor Su Xinghe was really a little calm.

Although he has always been nurtured by his son, Professor Su Xinghe still inevitably carries the imprint of many old-school intellectuals. For example, he thinks he's already written a book—more than one. There is no point in resending the paper, everything depends on the results.

For example, in the process of developing a 16-bit single-chip microcomputer, Su Xinghe creatively adopted a three-stage assembly line, which greatly improved the execution efficiency and stability, which was simply tailored for the field of industrial control.

There are so many pioneers in the scientific community in the country, who do you see who has published what papers abroad?

But Su Yuanshan is different, Su Yuanshan has always been smuggling his father, and he must submit papers...... He not only tried to get his father, but also kept trying to get a few senior brothers to publish them in foreign periodicals, even if they were not so influential.

This is not about "making foreigners recognized", but about influence.

So Professor Su Xinghe voted - first changed it once, and then after sending the sample of the 16-bit single-chip microcomputer, it passed at one time.

"Dad, you don't know...... This is really a big step for domestic semiconductors and even the domestic scientific research community. ”

Su Yuanshan took a deep breath.

The ISSCC (International Conference on Solid-State Circuits), known as the Olympics of chip design, only publishes the highest level of results in the field of integrated circuit design.

In addition, there is JSSC (IEEE Journal of Solid-State Circuits) – an extension of the ISSCC, which is equal in impact and value.

The conditions to go up are very simple, choose one or two or choose two.

The most awesome, creative.

The best and/or the first。

This also means that 16 microcontrollers as well as taken by the head of the house

You know, it was not until 2005 that the first ISSCC paper was born in mainland China.

In the following ten years, the average number per year was only one.

And Su Yuanshan, who has experience, knows that before the 90s, the domestic scientific research community was basically the same as his father, just burying his head in it, and then participating in any foreign conference with an attitude of "knowledge" and "learning".

It was not until the mid-to-late 90s, when a large number of turtle scholars returned to China, that they slowly began to expand their horizons as a whole, so as to actively embrace the international scientific field, actively publish journals, and then establish and improve the future thesis system.

Moreover, the main significance of this ISSCC is that it means that the mainland has gone from a "sanctioned" single-chip microcomputer blind spot to an international advanced level.

......

After chatting with his father for a few more words, Su Yuanshan hung up the phone and sat on the sofa laughing.

"I feel happier than if you published your paper yourself. Zhou Xiaohui pursed her lips and quipped on the side.

"Well, how old is my dad? Su Yuanshan was a little proud: "Hehe, but I also have my credit." ”

Zhou Xiaohui didn't know how to answer this sentence, but just smiled.

Su Yuanshan grabbed his mobile phone and looked at the time, and ordered: "Let's stop here today, get up at eight o'clock tomorrow morning, and we will leave on time at nine o'clock." ”

"Good. Zhou Xiaohui responded and began to pack up the documents.

The next day, the two were driven by a driver from far away to the science and technology park again.

In the morning, Su Yuanshan and Zhang Rujin communicated alone for nearly two hours, and after lunch, he talked with Shengguangfeng, Italian Alzide and others separately.

Of course, he can't talk about encouragement, but as the actual controller of Yuanxin, he must show enough sincerity and attention to these people who have come to Shanghai from thousands of miles away.

In the afternoon, Su Yuanshan refused Zhang Rujin's request to send him out of the factory, and only Chen Jianguo accompanied him out of the factory.

......

"Xiaoshan, I don't lie to you. To change from aluminum to copper, it is really not an ordinary difficulty. ”

Chen Jianguo put his hands in his pockets, kept kicking the small stones on the ground, and his brows furrowed into a deep Sichuan character.

He looked up at Su Yuanshan: "The copper conduction process involves chemical and physical vapor precipitation...... I now deeply feel that I don't have enough knowledge. ”

"It's okay, there's no hurry. Su Yuanshan smiled and comforted: "No one is born with it, learn slowly." ”

“...... I think you were born to be. ”

Su Yuanshan: "......"

"Senior brother, don't worry. Su Yuanshan stared at Chen Jianguo and said softly: "Where you can't learn, I don't want you to produce results, what are you anxious about?"

Chen Jianguo looked at him straightly: "Where will you not learn?

"Uh...... I can't say that either, I mean, when you understand the big principles, you can control the big picture, and you don't need to be specialized in every step. All you need to do is know the direction, determine the goal, and try to get your team to drill in the direction. ”

"Having said that, I always feel very unhappy when I see that the experiment has been failing, and then the money is still burning. ”

"Huh...... Where is this burning?" Su Yuanshan put his arm on Chen Jianguo's shoulder, and his atmosphere was not panting: "Seven years, five hundred million US dollars—is it enough?"

"I rely on ......"

"Really, senior brother, I don't lie to you, that's not technology, it's direction. ”

Chen Jianguo held his breath to his abdomen.

He knew that once Su Yuanshan said the direction, it must be the direction. As long as it is the direction, then even if the head is broken and the blood flows, you have to break through.

He clenched his fists and said a little viciously: "Okay! Seven years, Lao Tzu will not be able to study for a doctorate again!"
