The passionate years starting from the college entrance examination

Chapter 215, Desperate Difficulty

When Liu Guanzhong heard this, he immediately reacted.

Cheap?

That definitely can’t be cheap!

The other party was Howard, a businessman from North America. Liu Guanzhong still clearly remembered the other party's information.

"It seems that we have to ask the North American side to inquire about the news."

While thinking about this, Liu Guanzhong unconsciously adopted the tough attitude he had when selling transistors.

"Mr. Howard, you should know very well that the diaper launched by our China Resources Company uses super-absorbent polymer and also adopts a more close-fitting design."

"Look, there are diapers of different sizes, styles and functions. They have good breathability and very good softness."

"No matter which diaper you choose, it can provide your baby with higher comfort and keep you dry."

"As far as our current price is concerned, it is already the best price. You can't find better diapers than ours on the market."

After entering the role, Liu Guanzhong became a qualified salesperson.

Howard was stunned for a moment.

If Chen Guohua, who is far away in the capital, knew that due to selling transistors and chips, the original general manager of China Resources actually turned into a qualified diaper salesperson in an instant, he would definitely be shocked.

After a while, Howard finally reacted.

The price difference of three cents. If the goods are purchased in large quantities and shipped by freighter, the average transportation cost will definitely be less than 0.5 cents.

Then if we raise the price a bit, lower than P&G's 0.5 cents a piece, we should be able to make some profit.

Moreover, this diaper from China Resources has better performance, comes in many styles, and can even be used by adults.

If this is the case, then this business can still be done.

But if the price can't be reduced by a penny, Howard always feels like he's at a disadvantage.

Unfortunately, he was facing Liu Guanzhong.

So he had to accept this price.

But faced with the huge order suddenly placed by Howard, which required the purchase of at least 500,000 pieces of diapers, Liu Guanzhong did not dare to agree immediately.

Just because the factory in Baiyun City cannot produce so much.

The matter quickly spread to the capital. Sitting in his office, Qiu Zongyue was shocked to learn that a small diaper could be sold for 0.8 US dollars a piece.

The total price of 500,000 Hushubao diapers exceeds 400,000 US dollars.

According to Howard's plan, the contract is divided into three steps. The first batch is 50,000 pieces, and he only needs to pay a deposit of US$10,000.

If subsequent sales are good, he will continue to purchase more.

To put it bluntly, he just wants to be a free hand.

Ten thousand US dollars is all the cash Howard can come up with. For the remaining money, he still needs to borrow money from the bank.

This means that he needs to return to North America and get a house and a bank loan before he can return to Hong Kong Island, fulfill the contract with China Resources, and pay for the goods.

The reason why they opened the contract for a total contract of 500,000 pieces was naturally because they wanted to lock in the output of China Resources Company.

Otherwise, if Howard sells out 50,000 diapers and China Resources itself brings the goods to North America for sale, then he will definitely cry without tears.

A qualified businessman is good at discovering business opportunities and is a qualified gambler.

After all, the opportunity is fleeting, and Howard will not believe that others will wait for him.

After reading the information, Qiu Zongyue went to Zhenhua Research Institute to find Chen Guohua.

The latter is quite puzzled. Shouldn't he be looking for Xue Yajun lately? What are you looking for?

It wasn't until Chen Guohua heard about diapers that he realized that Baiyun City had actually produced diapers.

It seems like the diapers sent to him were also on the train, right?

"Leader, this matter depends on whether the superiors want to earn this foreign exchange."

Hearing this, Qiu Zongyue rolled his eyes and said, "You must earn it. Although it is only 400,000 US dollars, no matter how small the mosquito's legs are, they are still meat."

Listen to this tone, how big it is!

If it was back in 1958, Qiu Zongyue would never have thought that he would one day berate Fang Qiu like this.

After all, four hundred thousand US dollars is not a small amount of money.

But in the past year or two, Qiu Zongyue has seen big scenes.

What is often discussed are big businesses worth tens of millions or billions of dollars, so when faced with a small business worth 400,000 U.S. dollars, Qiu Zongyue would call it a "mosquito's leg."

Chen Guohua couldn't stop laughing and said:

"If you want to make money, it's very simple. Just notify Baiyun City directly to expand operations, but you must also remember that this is a market economy behavior, so be vigilant."

"Then what should so many workers do if they don't place orders?"

When Qiu Zongyue heard this, he subconsciously wanted to directly answer that there were layoffs.

However, when the words came to his lips, he still held back.

In July last year, there were indeed direct layoffs.

Many workers returned to the countryside and continued to be farmers.

That's more than 20 million people.

Quite helpless!

But this time things are obviously different and cannot be handled casually.

Besides, it's not Qiu Zongyue's job to handle it, so it's better not to make casual suggestions.

"Then what do you think we should do?"

"What I mean is, how about letting China Resources take charge directly? They need to find good sales."

Chen Guohua said lightly.

After all, China Resources is located on Hong Kong Island, so it doesn't seem impossible for them to go to North America.

Anyway, if it's just an economic behavior, it won't be a big problem.

As long as you make money, you can purchase raw materials and bring them back.

Where to purchase raw materials? Isn’t it simple?

Today's U.S. dollar is linked to gold, and many economies around the world recognize the U.S. dollar as a currency.

The mainland is still in short supply of various raw materials, otherwise it is industrial equipment.

But industrial equipment, even if it is second-hand, will not be sold.

Even though the current situation is very strange, there is still a necessary blockade.

Do you want to ship industrial equipment such as machine tools to Hong Kong Island for trading?

Haha, don’t even think about it!

Even scrap metal won't work.

"Okay, I understand, I will apply with the above."

Hearing this, Qiu Zongyue nodded, indicating that he understood.

After a pause, he continued to ask:

"By the way, you have been busy in the laboratory recently and haven't told me about any progress. Why don't you tell me now?"

Chen Guohua heard this and said with a smile:

"Leader, what do you want to know? Do you want me to tell you about the current excimer laser technology, or the aluminum gallium arsenide semiconductor laser?"

"Can't you give me a results report that I can understand?" Qiu Zongyue rolled his eyes and said:

"For example, when will we be able to produce a chip with 10,000 or 100,000 transistors built in?"

After hearing the leader's words, Chen Guohua pondered for a moment and said:

"In fact, it is now possible to prepare chips with 100,000 built-in transistors, but I still want to be on the safe side."

"why?"

Qiu Zongyue was immediately puzzled, but Chen Guohua directly said two words: rat!

Yes!

The previous mouse was not found, so if Chen Guohua took out such a chip rashly, he would probably be targeted.

In fact, Chen Guohua thought again, how about using this to lure the snake out of its hole.

After all, this mouse has been hiding for so long, always trying to get a big one and sell it at a good price.

The game between Chen Guohua and Mouse has been going on for several months, and it's not over yet, which naturally makes the former very uncomfortable.

Therefore, even if he developed excimer lasers and other related equipment, Chen Guohua did not make any announcement.

But if this continues, it will not be an option after all.

But the trick of luring a snake out of its hole may not work sometimes.

Just because the mouse was able to hide for so long without being discovered, he must be a very patient angler.

So, it’s difficult!

"Then just wait and see?"

When Qiu Zongyue heard this, he was also very unwilling.

Chen Guohua couldn't help but feel happy when he heard this and said:

"That's definitely not the case. The reason why I don't take out the chip now is that, in addition to this reason, there are still some components that have not been upgraded yet."

"Besides, it won't take long, either at the end of this month or at the beginning of June, I will definitely take it out."

"There is also hard disk memory based on flash memory, which also requires such a chip. I will definitely not wait too long."

"Although rats are hateful, there is no way I would stop just to catch them."

There are two other things, that is, the relevant research on the optical lens has not been completed yet.

Not to mention the same is true for fiber optic communications.

After solving the problem of optical fiber communication, if you want to notify others in the future, the speed will become very fast.

Chen Guohua can even solve the current situation of telephone communication.

After all, today's telephones are still the same as before. It is very troublesome to have to transfer every call.

But if it is improved, there will no longer be troubles on these levels.

For now, Chen Guohua thinks there is no problem in doing so.

"By the way, leaders, if we really need to manufacture chips, then the power plant must communicate clearly to avoid problems."

Suddenly, Chen Guohua thought of something.

That's the thing about power plants.

Nowadays, Zhenhua Research Institute has many places that need electricity.

Lasers, photolithography machines, ion implantation equipment, etc., as well as the fifty computers in the software programming laboratory, are all large power consumers.

And if chip manufacturing of hundreds of nanometer transistors is started, power consumption will reach a peak.

In particular, Zhenhua Research Institute basically works during the day and is not on duty at night.

In other words, when all major electricity consumers will start up, the pressure on power plants will be very great.

"Need a lot of electricity? Aren't current power plants large enough?"

When Qiu Zongyue heard this, he was immediately surprised.

Chen Guohua shook his head and said:

"According to the approximate amount of electricity I know now, it can basically be maintained at a balanced state every day."

"But if you start up other equipment such as photolithography machines, the power consumption will be terrible. After all, the current power plants are not enough."

"Except when we make chips, either those fifty computers don't start up, or other labs don't start up those devices."

The more he heard Chen Guohua say this, the uglier Qiu Zongyue's face became.

Although Zhenhua Research Institute makes money at a very fast rate, the energy it consumes is also terrifying.

At present, I am afraid that two more generating units will need to be installed in the power plant, and the supply of coal will also need to be increased.

Today’s power plants are actually coal-fired power plants.

Even in 2023, half of the country's electricity consumption was actually coal-fired.

Among them, Datong’s coal resources supply more than half of the country.

"Okay, I see."

Qiu Zongyue left gloomily, and Chen Guohua shook his head without saying a word.

He just couldn't be bothered to explain to the other party.

I am so happy when I make money, but when I have to spend money, I feel like my father is dead.

Don’t you understand the simple truth that only by giving can you get rewards?

Of course it's not that I don't understand, it's just that I feel sorry for the wasted resources.

Everyone hopes to have free prostitution, or to have pie in the sky.

Unfortunately, this is impossible.

In the laboratory, Chen Guohua summoned researchers from several laboratories to explain technical issues to everyone.

"We all know that with the continuous optimization of transistor structures and the reduction of transistor sizes, the goal is to integrate more transistors per unit area."

"To achieve this goal, in addition to making the transistors smaller, we can also create a spatial dimension, so that more transistors can be stacked and integrated within a unit area."

“Now the question is, how to stack transistors?”

All the researchers, including Yang Yuhe, Qian Yuanxing, Dong Jianchang and Wan Fusen, listened attentively.

No one interrupted Chen Guohua's speech.

"From a theoretical level, there are roughly two ways."

Chen Guohua smiled and said in a very calm tone:

"The first one is to make the transistors into multi-layers on the wafer through a special process; the other is almost the same as our previous process, that is, to make a layer of transistors on the wafer, and then put multiple layers on it. The wafers are stacked, and the wafers are connected through through-silicon via technology."

"Let's talk about the first method first."

Whether it is a chemical vapor deposition equipment laboratory, a transistor laboratory, or a lithography machine laboratory.

All the researchers looked surprised.

They have also read the relevant technical information provided by Chen Guohua.

But to be honest, they don't understand the more detailed technical parts.

From a theoretical level, Dong Jianchang and others can understand the two methods mentioned by Chen Guohua.

The technical difficulty of the first method is that the upper transistor does not have a dense silicon substrate as a support, making it difficult to produce high-quality transistors.

What's more, it seems that there is currently no way to perform such stacking.

Because technically, it is not possible yet.

The second method is relatively simple. After all, it is a high-density advanced packaging technology, but it also has a technical difficulty, that is, it must break through through silicon via technology.

Chen Guohua also mentioned this. The first method requires time to settle to make technological breakthroughs.

But the second method can actually be tricky.

“So, what exactly is through silicon via technology?”

Upon hearing Chen Guohua's question, the conspicuous Bao Wan Qingxuan immediately raised her hand to answer the question.

She wanted to answer the questions to prove that she was paying attention to the lecture and was not distracted.

Seeing how expressive she was, Chen Guohua couldn't help but smile.

Wan Qingxuan, a female classmate, had been frightened by his name before, so she was very proactive in every class like this.

"Okay, you can tell me, but if what you say is wrong, you will be punished."

"No way, hum!" Wan Qingxuan snorted arrogantly, and then said seriously:

“As the name suggests, through silicon via technology is to achieve vertical electrical interconnection through silicon vias by creating vertical connections between chips and wafers, and filling them with conductive materials such as copper, tungsten, and polycrystalline , a technology that realizes interconnection between chips.”

"Okay, just barely correct, just applaud and encourage yourself."

Hearing Chen Guohua's words, Wan Qingxuan suddenly narrowed her eyes and laughed.

In the following time, Chen Guohua gave a more detailed explanation of this through silicon via technology.

In fact, there is no need for Zhenhua Research Institute to conduct such technological research and development.

But Chen Guohua knows that currently he can only use this tricky technology to stack more transistors to improve chip performance.

Judging from the existing technology system, it is undoubtedly very difficult to break through smaller transistor size technology.

Not to mention the more distant transistor technology that only has two-digit nanometer level, let’s just say that the transistor technology that is only at the level of less than 500 nanometers is enough to block people from the door for a long time.

If it is single-digit nanometer-level transistor technology, haha, then it needs to involve extreme ultraviolet lithography machine technology.

The extreme ultraviolet lithography machine is known as one of the most complex machines in human history.

Because this thing involves too many technical aspects and high-precision components.

Of course, Chen Guohua didn't tell everyone about this.

But after all, everyone's curiosity could not be escaped. As soon as Chen Guohua sat down and was about to eat, Zhang Jichuan sat down. "Old Chen, while you have time now, why don't you tell us about this extreme ultraviolet lithography machine technology?"

In the cafeteria at noon, Zhang Jichuan licked his face, looking like a curious baby.

Behind him, several more people came.

They were all sitting next to Chen Guohua. In addition to Zhang Jichuan, there were also Xue Jinquan, Dong Jianchang, Lu Zijing and others.

These people were all the small project leaders who were most valued by Chen Guohua at the beginning and are currently in charge of several laboratories.

At the same time, they are also super academics, such as Yao Shiqiong, who is now in charge of the software programming laboratory.

There was also the former Gu Xiaofeng, who was transferred by Chen Guohua to the excimer laser laboratory that was just established.

At this time, after hearing Zhang Jichuan's words, Gu Xiaofeng and Yao Shiqiong also became curious.

"Old Chen, please tell me quickly. Don't go into detailed technical details, just give a general outline."

Xue Jinquan also urged, and Chen Guohua immediately glared:

"You are not engaged in the research and development of photolithography machines. Why do you know this?"

"Old Chen, look at what you said. In the optical instrument laboratory I'm in charge of, aren't many components and components related to photolithography machines?"

Chen Guohua rolled his eyes at Xue Jinquan speechlessly, "Stop joining in the fun. If you want to listen, then open your ears."

Anyway, it’s just a rough outline, and it won’t involve the technical aspects.

Besides, how can you possibly talk so much while just eating?

"If we manufacture an extreme ultraviolet lithography machine, we first need to generate extreme ultraviolet light. So do you know what technology and equipment is involved?"

In one sentence, Chen Guohua couldn't help but take on the role of a teacher.

But Xue Jinquan and the others did not interrupt him. Anyway, Lao Chen often asked and answered questions like this in class.

"As we all know, there are no light bulbs in our world that directly produce extreme ultraviolet light."

Whether it is the mercury lamp of the previous generation of lithography machines or the current laser that uses excimer lasers based on krypton fluoride to generate deep ultraviolet light, the technical content is relatively low.

"So what should we do?"

Chen Guohua smiled and then said:

"This requires making a small tin ball with a diameter of only 30 millionths of a meter, and then allowing it to move at a speed of 325 kilometers per hour in a vacuum."

"Then the laser is used to strike twice. The first strike is to increase the temperature of the small tin ball, and the second strike is to make the small tin ball explode."

"After the small tin ball explodes, it will turn into a plasma with a temperature of up to 500,000 degrees."

Wow!

Xue Jinquan and others all exclaimed, but immediately covered their mouths.

The other tables nearby couldn't help but become quiet, listening to Chen Guohua's speech quietly.

In fact, Chen Guohua's voice is not loud, which is the decibel level that Yao Shiqiong and the others can hear.

Zhang Jichuan couldn't help but whispered:

"Five hundred thousand degrees? This temperature is higher than the surface temperature of the sun. It's terrifying!"

It is indeed outrageous!

No wonder Chen Guohua never told everyone about this before. It turns out that the technology involved is indeed terrifying.

This alone is difficult to do.

Chen Guohua just glanced at Zhang Jichuan and the others, and then continued:

"To achieve extreme ultraviolet light that can be used for photolithography, this process of spraying tin needs to be repeated 50,000 times per second."

Hearing this, Yao Shiqiong's eyes suddenly widened.

Fifty thousand times per second, what exactly is this concept? How much energy does it need to be consumed?

And, what kind of technology can achieve this?

"Xiaofeng, you are responsible for the research and development of excimer lasers, and you may be familiar with lasers, but let me tell you, the kind of laser I just mentioned, haha, it is estimated that it will be difficult to realize even if our Quan Zhenhua Research Institute puts it together. "

After hearing Chen Guohua's words, Gu Xiaofeng was stunned for a while.

Even Zhang Jichuan and others were a little unconvinced. Is it so difficult?

Chen Guohua saw everyone's expressions but said nothing.

"I can tell you that this is a type of laser called carbon dioxide, but do you know? Eighty percent of the energy is converted into heat, and only 20% is laser."

"So this involves a heat dissipation issue. We all know that computers use fans to dissipate heat, right?"

"But the lithography machine requires a fan speed of one thousand times per second, so ordinary physical bearings simply cannot bear it."

"So, this requires the development of a magnetic levitation fan to deal with the heat dissipation problem."

hiss!

Hearing this, Zhang Jichuan and the others felt their scalps go numb.

Although they were previously students majoring in computational mathematics at Peking University, they also learned a lot about technology during the past two years when they followed Chen Guohua to develop integrated computers.

Therefore, just from the technical requirements they just heard, they knew how difficult it was.

Magnetic levitation fan?

What a great guy!

Seeing their expressions, Chen Guohua smiled with satisfaction and said:

"Don't be too surprised. There is also the problem of the reflection of the tin ball when the laser bombards the small solder ball, and how to ensure the constant density of the tin ball gas."

Everyone hurriedly listened attentively, this was definitely the moment for another big move.

“Especially in order to guide the laser to hit the solder ball accurately, industrial diamonds are needed.”

diamond?

Gu Xiaofeng and Yao Shiqiong's eyes suddenly lit up. They still liked diamonds very much.

Although they have never seen diamonds, they have been mentioned in novels and movies.

“For such industrial diamonds, ultra-high purity diamonds must be required.”

"Therefore, these problems alone show how high the requirements for laser development are."

"Such a laser requires at least hundreds of thousands of parts."

hiss!

At this moment, Gu Xiaofeng felt a lot of pressure.

Obviously she has just been in charge of excimer lasers and researching the applications of this laser in other fields.

As a result, I now heard Chen Guohua talk about the research and development of carbon dioxide laser, one of the components of the extreme ultraviolet lithography machine, which actually involved many thorny problems and required the construction of hundreds of thousands of parts.

Just thinking about it is not enough.

"Can't you stand listening to this?"

Seeing everyone's gaze, Chen Guohua smiled happily and said:

"Even if the laser is manufactured and successfully bombards the solder ball, the extreme ultraviolet light generated still needs to be collected. How to collect it?"

"It just requires a special mirror. However, the wavelength of extreme ultraviolet light is too short and the reflectivity of ordinary optical materials is too low, so most of it will be absorbed."

"Just to make such a mirror, haha, it might not even be possible without twenty years of effort."

At this point, Chen Guohua did not continue to introduce the component structure of the extreme ultraviolet lithography machine.

Because the entire photolithography process of the photolithography machine actually only involves so much.

First, a carbon dioxide laser is used to emit laser light at a small tin ball to produce extreme ultraviolet light.

Then some special mirrors are used to collect the extreme ultraviolet light and then transmit it to the silicon wafer.

In this way, the chip can be accurately carved on the silicon wafer.

Therefore, the most difficult parts, which are also the most challenging technical parts, are actually the carbon dioxide laser and mirror that Chen Guohua just mentioned.

In other words, the process of how to generate extreme ultraviolet light and collect it is the most important.

"So such a photolithography machine involves many disciplines such as mathematics, optics, fluid mechanics, polymer physics and chemistry, surface physics and chemistry, precision instruments, automation, software, and pattern recognition."

"In addition to the two components I just mentioned, our existing scanning electron microscopes, energy controllers, detectors, mask tables and other components also need to be technologically updated."

"So you ask, can we build such a lithography machine now?"

Faced with Chen Guohua's questions, Zhang Jichuan, Xue Jinquan, Yao Shiqiong and others were silent.

They wanted to say yes!

After all, Zhenhua Research Institute makes lithography machines. If they can't make them, then who can?

In this era, the mainland is actually the luckiest.

Just because there are many high-end scientists in the mainland now.

Such as Qian Sanqiang, Deng Jiaxian, Guo Yonghuai, Peng Hengwu, Hua Luogeng, Qian Xuesen, Dai Xizhang, etc., they are all the protagonists of this era.

And there are quite a few people who have the same backbone.

Therefore, if these people are gathered to develop extreme ultraviolet lithography machines, there must be no problem.

But Chen Guohua felt that this was not necessary, and it was impossible for him to gather so many people.

What's more, extreme ultraviolet lithography machines don't need to be manufactured now.

When Zhang Jichuan and the others were silent, Chen Guohua suddenly said:

"By the way, there is another problem here, and that is the problem of power consumption. It is estimated that if we can really develop such a lithography machine, the daily power consumption alone will exceed 30,000 kilowatt hours."

hiss!

Zhang Jichuan and the others suddenly took a deep breath, and their expressions became very incredible.

"Does it really need to consume so much power?"

Gu Xiaofeng couldn't help but asked in amazement, her eyes widening.

As a researcher at Zhenhua Research Institute, although she is currently only a part-time researcher, she is still very concerned about electricity use.

Not only Gu Xiaofeng, but also Zhang Jichuan, Xue Jinquan, Lu Zijing and others are also very concerned about the issue of electricity consumption.

Therefore, they learned from newspapers that last year, in 1960, the country's total power generation was 59.4 billion kilowatt hours.

According to what Chen Guohua just said, the power consumption of an extreme ultraviolet lithography machine is 30,000 kilowatt-hours per day. Then, if a lithography machine is used for 1.98 million days, it will consume the total power generation of the entire country last year.

But, this is just a photolithography machine.

Yao Shiqiong and others were speechless, and Chen Guohua did not continue to talk about this matter because he had already finished his meal.

Since we have already eaten, let’s just end today’s chat.

Just when Chen Guohua thought this was just a simple science popularization, Qiu Zongyue suddenly found him two days later.

"Guohua, you said two days ago that there is such a lithography machine that consumes 30,000 kilowatt hours of electricity every day?"

At this moment, Qiu Zongyue looked very nervous.

A photolithography machine consumes 30,000 kilowatt-hours of electricity. Which power plant can sustain this?

As we all know, one ton of standard coal can generate electricity of 8,130 degrees, but this is only a theoretical state, and it is actually impossible to reach such a standard.

During the energy conversion process, huge losses will occur due to technical and other reasons.

According to the current power generation technology of thermal power plants, every kilowatt hour, that is, one kilowatt hour of electricity, consumes about 410 grams of coal for power supply.

One kilogram of standard coal can generate about 2.5 kilowatt hours (three kilowatt hours) of electricity, and one ton of standard coal can generate 2,500 kilowatt hours of electricity.

To put it simply, the current technology is not good enough.

In addition to the problem of the generator set, there is also whether the coal is fully burned and whether all the energy is utilized.

In addition to power generation, some electricity is also lost during transportation.

For this reason, Zhenhua Research Institute established a laboratory for generating units and transmission equipment in order to improve technology in these areas and reduce energy loss.

Thermal power generation in the Mainland only started in 56 years.

That year, the first 6,000-kilowatt thermal power unit was successfully put into operation at the Huainan Power Plant. This ended the history of the mainland being unable to manufacture thermal power equipment.

After that, power plants such as 12,000-kilowatt units, 25,000-kilowatt units, and 50,000-kilowatt units were put into operation one after another in Shancheng, Zhabei, Northeast and other places.

But these are all due to the fact that after July last year, the power plant also stopped making rapid progress.

It is almost expected that the national power generation capacity will be cut a lot this year.

At present, the thermal power plants outside Beijing are actually generator plants with 6,000 kilowatts or around 3,000 kilowatts.

Based on this, Qiu Zongyue came over to ask Chen Guohua so worriedly.

When the latter heard the other party's question, he couldn't help but rolled his eyes:

"Leader, who did you hear the news from? Why did you hear half of it but not the other half?"

"I said two days ago that there is such a photolithography machine that consumes 30,000 kilowatt hours of electricity every day."

"But I have also said it at the same time, and I emphasized it before talking about the lithography machine. With our current technology and talent reserves, we simply cannot build this lithography machine."

Hearing this, Qiu Zongyue breathed a sigh of relief.

But the topic was changed again.

"You just said that we can't build such a photolithography machine? Is it difficult?"

"Of course it's difficult!"

Chen Guohua looked helpless and said lightly:

"Building such a photolithography machine is much more difficult than building mushroom eggs, airplanes, nuclear submarines, etc. It is the most complex and sophisticated equipment in human history, bar none."

Qiu Zongyue was suddenly completely aroused, and suddenly lowered his voice and said:

"According to what you said, is it possible to use such technology for fishing?"

"no!"

After hearing this, Chen Guohua refused without hesitation.

So what if I take it out?

That mouse could hide so deep for so long, how could it be so stupid?

Besides, he had said early on that it was best not to let foreigners know about equipment such as photolithography machines. Otherwise, they would follow the pictures and catch up soon.

Chen Guohua is not so arrogant and thinks that even if IBM knows the names of these devices, it will be of little use.

Haha, there are many national laboratories such as Bell Labs, Northrop Research and Technology Center, Sandia National Laboratories, etc.

These are all laboratories that have participated in theoretical research and technology development such as photolithography machines in the history of time and space.

In other words, as long as researchers in these laboratories have a direction, they can definitely build a photolithography machine within a few years.

Maybe the technology of the photolithography machine at the beginning was still a little behind.

But as long as there are no problems with business operations, they can gradually improve and meet the requirements for running a business.

They have funds and talents, and there is no shortage of technology. When it comes to research and development, it is really just a matter of time.

So, how could Chen Guohua take the initiative to expose it?

Even if it is used for fishing, that won't work.

After all, if the other party doesn't take the bait, wouldn't it mean that all the hard work has been in vain?

Qiu Zongyue didn't feel disappointed when he heard this.

Perhaps, in his opinion, the mouse that Chen Guohua thought before actually did not exist at all.

Otherwise, so much time has passed without any sign.

And the chips delivered to IBM have been completed one after another.

It means that the mouse missed out on another great wealth.

"In that case, I won't bother you anymore."

"If you have any research plans in the future, you must inform me first, and tell me about the power consumption problem in time, otherwise, you may not be able to handle it by then."

Chen Guohua nodded, indicating that he understood.

After Qiu Zongyue left, he immediately went to the generating unit and power transmission equipment laboratory to take a look at the current research and development progress.

In the mainland, the first 'power grid' was in the Magic City in 1882.

In fact, strictly speaking, this was just a low-voltage transmission line at that time and could not be regarded as a power grid.

It was not until 1936 that, as the installed capacity of power plants increased and the scope of power supply expanded, high-voltage transmission lines with more than 10,000 volts appeared, and the power grid was gradually formed.

Then in 1937, in order to plunder the resources of Northeast China, Tokyo established the first inter-provincial high-voltage power grid in the mainland with a maximum voltage level of 220,000 volts.

After the founding of New China, in 1954, Moscow's "Pravda" published a piece of news from the mainland on its front page:

The first 220,000-volt transmission line designed and constructed by mainlanders was completed on January 23, 1954.

During this period, the highest voltage power grid operating abroad was the 380-kilovolt line built in Europe in 1952.

Therefore, the 220,000-volt line is still among the world’s advanced levels.

However, Chen Guohua looks down on these technologies.

What he needs is technical equipment to improve power generation efficiency and reduce energy loss, not to compare with anyone.

What is there to compare with?

Living your life behind closed doors is better than anything else.

Seeing Chen Guohua walk in, many researchers in the laboratory were very surprised.

"Director, you are here, come on, come on, we really have a lot of questions that we need to ask you about."

Gui Zhiting immediately said with great joy, hurriedly pulled Chen Guohua, and then took out his notebook, which had already been filled with dense notes.

It's just that these words are really ugly, like ghost drawings.

"Yes, I'm quite serious. Even with this word, I still haven't made much progress."

Picking up the notebook, Chen Guohua said with a smile. Gui Zhiting suddenly blushed and felt embarrassed.
