Chapter 220 The First Year of the Rise of China’s Semiconductors

Suddenly, Lin Guowen found a topic to chat about.

After hearing this question, Lin Xiao felt relieved and said quite complacently: "Of course they are all studying my multidimensional field theory."

"Huh? Isn't multidimensional field theory a theory? Is it also cutting-edge science?" Lin Guowen asked.

Lin Xiao was dumbfounded: "Why is theoretical research not considered cutting-edge science?"

"I thought they were rockets and photolithography machines."

"What you're talking about is cutting-edge research in applied science, so to speak."

"That's it." Lin Guowen said.

Lin Xiao shook his head helplessly. It was better not to argue with his father about these issues.

However, Lin Guowen obviously intends to continue the conversation: "But tell me, haven't we all over the country been researching photolithography machines in recent years? Photolithography machines are just like printers. Why can't we research them?"

Lin Xiao spread his hands and said: "The two are not the same thing. The printer can only print one word on 1 cm paper, but the photolithography machine can print ten million words. The photolithography machine uses photolithography, and light is very

short."

"It's just about controlling variables." Lin Guowen said, "So our country's science and technology is still not developing well."

Listening to his father's words, Lin Xiao didn't know what to say, but the words "control variables" suddenly appeared in his mind, and he couldn't help but be stunned.

Control variables?

Thinking back to the model of the lithography machine in his mind, he suddenly felt that he had found a feasible optimization solution.

Optimizing a technological product should be analyzed from the perspective of control variables!

What are the variables of a lithography machine?

Light path, reflective lens, light source...etc.

The problem he has been struggling with before is related to these things. Because the photolithography machine needs to engrave at the nanometer level, it also has requirements for the accuracy of these things. It also has to reach the nanometer level. This needs to mention an important point.

Components, that is, servo motors, servo motors are engines that can control the operation of mechanical components, but China still lags behind foreign countries in this regard.

So what he has been thinking about is how to create a servo motor that can also reach the nanometer level of precision.

This again requires the depth of a country's industrial technology, not the breadth. This is also the shortcoming of China's industry. There is breadth, but the depth is not enough.

The accuracy of the servo motor is definitely the most critical in-depth evaluation criterion.

Photolithography machines need it, and machine tools called industrial mother machines also need it.

However, due to poor research on basic materials, the accuracy of Huaguo's servo motors is not high.

So, this is the variable that Lin Xiao needs to control.

By controlling this variable well, many problems with the lithography machine will be easily solved.

Therefore, Lin Xiao has his first goal, which is to improve the accuracy of the current servo motor!

Thinking about the information in your mind, there is absolutely a chance to realize this.

He took a deep breath, feeling a little excited, and then said to his father: "Dad, everything you said is right."

Lin Guowen laughed: "Of course I'm right."

Without complaining about where her father's honeyed confidence comes from, Lin Xiao then said to her parents: "By the way, Dad, Mom, I may be busy in the next year. I don't know if I will come back next year."

.”

Father Lin and Mother Lin were both stunned: "What's wrong?"

Lin Xiao said: "I have to do something more important."

Hearing Lin Xiao suddenly say this, Father Lin and Mother Lin were a little confused, but they didn't ask any more questions. Lin Xiao was already an adult and had his own ambitions.

Father Lin patted him on the shoulder and said, "Go ahead and do it. Men should do big things. Dad believes in you."

Mother Lin also said: "Mom also believes in you. You will come back sooner or later anyway. It's okay."

Lin Xiao nodded slightly: "Yes."

…

Time passed quickly, and Lin Xiao did not stay at home for a full year, but returned to Beijing three days before the Lantern Festival.

School started on March 1st, and there was about a week left, but Lin Xiao did not take any time off. When he came back, he took out his mobile phone and called Ma Gaoliang, the director of the Science and Technology Bureau.

At this time, Director Ma Gaoliang of the China Science and Technology Bureau was dealing with various matters in his office.

The Science and Technology Bureau has the right to manage matters related to science and technology across the country, such as applications for various national science and technology awards. Although this is mainly the right of the National Academy of Sciences, the opinions of their Science and Technology Bureau also have a high reference proportion. In addition

Various major national science and technology projects also require their approval, as well as the supervision of various scientific research funds, etc.

All in all, China's scientific community is a huge system, and the Science and Technology Bureau is one of the most important regulatory agencies. Of course, this means that things are relatively busy.

After Ma Gaoliang signed an important policy document, he rubbed his eyes and asked his secretary to get him a glass of water.

"I'm so busy even before the New Year is over. I guess I'll still be busy until April or May."

He sighed.

But just as he finished sighing, he suddenly saw his cell phone ringing.

Picking up the phone and looking at the caller, he suddenly froze.

"Lin Xiao?!"

He suddenly became excited.

He has been waiting for this call for a long time.

In other words, after Lin Xiao came back, he had been waiting for Lin Xiao to call him.

Because he knew that as long as Lin Xiao called him, there would be something important that needed the country's help. Maybe it would be a big event that could promote the development of their country.

Why he thinks so is because he has never forgotten what Lin Xiao once wrote on that note. To this day, he still keeps that note and keeps it in his home.

Now, Lin Xiao finally called.

He was looking forward to what Lin Xiao would say.

Then, he said to his secretary: "You go out first, I have an important call."

When the secretary who was pouring water for the leader heard this, he left the office with doubts.

After the door was closed, Ma Gaoliang answered the phone.

He suppressed his excitement and asked, "Professor Lin, what's the matter?"

"Let's talk about it face to face. It's a more important matter."

Lin Xiao's voice came from over there.

When he heard these words, Director Ma Gaoliang suddenly felt like he was hearing the sounds of nature.

This is what he wants to hear!

More important matters still need to be discussed in person. He can't wait to know what happened that made Lin Xiao make such a request.

Then, he said: "Okay! Where shall we meet?"

"Just find a suitable place."

"OK!"

Director Ma Gaoliang said immediately.

…

Soon, in an inconspicuous tea restaurant, Lin Xiao and Ma Gaoliang were sitting in a small private room, drinking tea and ordering a few snacks.

Then he closed the door and Ma Gaoliang said with a smile: "This place is a place where we prefer to talk about things. With our official background, it is quite safe."

Lin Xiao nodded, "That's good."

"Professor Lin, can you tell me what's important now?"

“Do you know about silicon wafers?”

Upon hearing these three words, Ma Gaoliang's breathing suddenly became rapid.

Then he looked around nervously, and then whispered to Lin Xiao: "I know, I know this very well, do you want to develop in this area?"

Silicon wafers are the largest in the chip raw material market. If he, as the director of the Science and Technology Bureau, doesn't even know about this, he can really resign directly.

Nowadays, in the silicon wafer market, foreign companies have occupied a major share for a long time. Of course, he, the director of the Science and Technology Bureau, will be worried about this.

"Yeah." Lin Xiao nodded and said, "I now have some ideas about the production process of 12-inch silicon wafers."

"That's great!"

Ma Gaoliang became even more excited. 12-inch silicon wafers are currently the mainstream among all specifications of silicon wafers. Because the larger the silicon wafer, the more chips can be produced and the unit cost is lower. Therefore, like the previous 8-inch, 6-inch

Silicon wafers have gradually fallen behind.

However, due to certain problems in the production process, China does not have an advantage in the production of silicon wafers.
