Rewrite the Technological Landscape

At 1:57, Meng Qian waited for He Wenkang at the gate of the factory, followed by his male secretary Cai Yuan.

They simply said hello and entered the factory together. At the door, Meng Qian and Zhang Guoqiang looked at each other and smiled, but they didn't say hello.

"Mr. Meng, do you know why I brought you to the factory?" He Wenkang asked after entering the factory.

Meng Qian shook his head, he really didn't know.

"It's okay if you don't know, and I don't know either." He Wenkang smiled at Meng Qian, who was puzzled.

The entire factory has five workshops, a canteen, a dormitory, and a sports area.

He Wenkang led him to the factory building in the middle. As soon as he entered the door, he could see the equipment on both sides and the dense cables on the ground.

And the most conspicuous thing is a half-exposed "behemoth" on the right hand side of the door.

He Wenkang led Meng Qian to the equipment. Several employees in the factory greeted He Wenkang one after another, and at the same time looked at Meng Qian. After all, he often appeared at the gate of the factory recently. Someone also asked Zhang Guoqiang who he was, Zhang Guoqiang He only said that he came to understand the situation, without elaborating.

"Do you know what this is?" He Wenkang stopped to stare at the device for a while, then turned his head and asked Meng Qian.

"Lithography machine." Meng Qian responded in a low voice, and also stopped to stare at the lithography machine, a strange emotion welled up in his heart, lithography machine, how many Chinese people's hearts hurt.

He Wenkang turned his head slightly to observe Meng Qian's expression, but the emotion displayed on Meng Qian's face made him suddenly bewildered. How could he see a feeling of revenge for killing his father?

"Does Boss Meng know what these things are for?" He Wenkang, who didn't understand Meng Qian, drew a circle on the lithography machine and asked.

"I understand roughly, but not in detail." Meng Qian took two steps forward to see more clearly.

"Then let me briefly introduce to Mr. Meng." He Wenkang also took two steps forward and pointed to an oval-shaped thing on the far side of the device, "This is a laser, the one on the side is an energy controller, and the one below is a beam correction device." The device, these three things control the first step input of the light source. The most important part of this link is stability.

But it is a stability. Our Huaxia has not been able to control it well for so many years. Does Mr. Meng know why? "

Meng Qian shook his head.

"Does Mr. Meng know the daily power consumption of such a lithography machine?"

Meng Qian shook his head again.

He Wenkang glanced at the laser and said, "Start with 10,000 kilowatt-hours."

Meng Qian was a little surprised. He really didn't understand such details in later generations, and he has been understanding more upstream things in this life. "Is it because of the problem of energy conversion rate?"

"Yes." He Wenkang nodded at Meng Qian, "The average energy conversion rate of the lithography machine is less than one-thousandth.

So how to ensure a long-term stable high-power output is the first stability of the light source input, and the second stability is how to improve energy stability to improve the yield rate. You must know that once the final energy appears a little The error will affect the yield rate. The last stability is also the most basic stability. How to reduce power consumption through equipment stability.

An excellent laser and energy converter will affect the power cost of the enterprise and the yield rate of the product. "

"For a fab with three or four lithography machines, the annual photoelectric cost is tens of millions," Meng Qian subconsciously continued.

"Currently the quality of the equipment on the market can bring about twice the difference in power consumption." He Wenkang took a few steps to the right, "The energy from the energy controller will enter the beam shape setting device, and different beams will bring to different optical effects.

Then there is the energy detector. As I said just now, the energy error will directly affect the yield rate, so here is the second confirmation of the energy. The thing under the energy detector is called a mask, which is essentially a Glass engraved with chip circuits, similar to the film of a camera.

But just such a piece of broken glass, Mr. Meng guess how much it is? "

Meng Qian thought for a while and said, "Mr. He just give the answer directly."

He Wenkang smiled faintly, "One piece of broken glass is worth a million."

After finishing speaking, He Wenkang motioned Meng Qian to take two steps to the right, "The piece under the mask is the most important thing, the objective lens, Mr. Meng can count, there are a total of more than 20 lenses here, through these more than 20 lenses , the circuit diagram on the mask plate is scaled down, and then mapped onto the silicon wafer by laser, and the objective lens must also compensate various optical errors.

Boss Meng is also very clear about this thing, we can't handle it.

The following two platforms are the measurement platform and the exposure platform. The normal process is to measure first and then expose. The accuracy of the entire measurement platform is at the nanometer level, and the difference of 1 nanometer will not work. The automatic focusing system we use is designed by Americans. .

Well, this is a lithography machine that can be seen from the surface, but the technology is not limited to these, for example, do you see the transmission belt here? This is the transmission system, which is also at the nanoscale, and the acceleration system At the aviation level, the entire lithography machine also needs a shock absorption system, an environmental control system, a complete machine control system, an automated operating system, and so on.

This is the lithography machine. After it is modularized, the difficulty of each module is that of a reduced version of the lithography machine. "

He Wenkang suddenly felt a little talking to himself, and he didn't know whether he was speaking to Meng Qian or himself.

The two stopped silently in front of the lithography machine at the same time, each with their own thoughts.

He Wenkang is recalling everything he has done in the past, and Meng Qian is thinking about everything he should do in the future.

A few minutes later, the two glanced at each other inadvertently, and while they were looking at each other, He Wenkang suddenly turned his mouth up, and looked at the lithography machine again, "The semiconductor industry is really a place that swallows dreams.

Let's go, Mr. Meng, I'll take you to meet some leaders of the factory. "

"Wait." Meng Qian stopped He Wenkang, "I suddenly had an idea, would Mr. He play a game with me?"

"Game?" He Wenkang was confused.

"Well, let's play a mind-reading game." Meng Qian explained with a smile, "We asked each other questions, some questions about factory employees, and the two of us answered at the same time, and Brother Cai asked the answers, and see who of us guessed. How's that for?"

He Wenkang was even more puzzled, "What does Mr. Meng mean?"

"If Mr. He doesn't dislike my childishness, just play with me." Meng Qian smiled meaningfully.

Looking at Meng Qian's appearance, although he didn't know what he was going to do, He Wenkang finally nodded, "How do you come up with a question?"

"Let me come first." Meng Qian glanced around the factory, then pointed to a woman in her thirties, "Mr. He thinks that female employee, what does she think she has been up to recently?"

"Ji Xiaoli." He Wenkang almost blurted out, "She should be busy with research recently."

Meng Qian smiled slightly, "Then I guess she should be busy arranging the wedding recently."

He Wenkang took a sensitive look at Meng Qian, and then asked his secretary Cai Yuan to ask Ji Xiaoli. A minute later, Cai Yuan walked back quickly, with a slightly hesitant expression on his face, "Ji Xiaoli didn't say anything at first, but after asking, she Said that she is really busy with getting married recently."

He Wenkang looked at Meng Qian's expression again, and then he pointed in one direction, "How old is the man who is moving things?"

"42."

The answers of the two are naturally the same, and both are correct.

It was Meng Qian's turn to ask again, "That man over there, has he bought a house recently?"

He Wenkang glanced at Meng Qian's gesture, "I remember Xiao Fang said before that he would buy a house after the new year, so he should have already bought it."

"He didn't buy it." Meng Qian said with certainty, "His mother is sick."

"What? Xiaofang's mother is sick?" He Wenkang was startled, then looked at Cai Yuan, "Go and ask about the situation!"

After six reincarnations, Meng Qian was able to answer He Wenkang's question, but He Wenkang answered Meng Qian's wrong question. When it was He Wenkang's turn to ask again, he nodded subconsciously, "Mr. It's admirable."

"Mr. He misunderstood." Meng Qian said lightly from the side, "I don't want you to think that I am hardworking. When I really become the factory owner, it is impossible for me to understand the situation of every employee like I do now. .”

"Then Mr. Meng is this?"

"I got to know them in order to have a more comprehensive understanding of the current situation of the factory, to prepare for a smooth acquisition, and also to prepare for the post-acquisition arrangements.

As for today's game, it was just a whim, because I just wanted to prove one thing to Mr. He, everyone is an independent individual, and everyone will encounter various things at different stages of life.

For a person, thank God for being able to understand himself in this lifetime.

Can we be responsible for others? The truth is, we are not entitled or able to take responsibility for anyone else's life.

Sell ​​the factory to another semiconductor company to take the more stable old path, or sell it to me to take a different attempt. How different choices will affect employees is not something you can decide, nor can I decide. , is their own decision.

We are only responsible for ourselves.

Mr. He, now, I want to buy this factory.

Are you willing to sell? "
