Chapter 204, I must give you some popular science
Just like Zhang Jichuan and Zhao Jusheng back then, the situation in their hometown was so difficult.
Therefore, they have a strong persistence and obsession with food.
Regarding the simple thoughts and ardent hopes of this group of students, Chen Guohua said with a smile:
"I understand everyone's feelings and their predicament, but I also hope that everyone will understand our Zhenhua Research Institute."
"If there is an opportunity, I will apply with the above and try my best to transfer everyone to our Zhenhua Research Institute."
Regarding the quota for college students, Chen Guohua still has a lot on hand.
But these are nationwide, not specific to Peking University and Tsinghua University.
To be honest, he also wants to wrap up these students.
But, this is impossible.
And it’s not fair to college students in other parts of the country.
Therefore, Chen Guohua could only comfort them in this way.
All the college students were reluctant to leave Zhenhua Research Institute, but they had no choice but to go back after all.
Chen Guohua just seconded them to help.
After sending Chu Shenglin and others back to Peking University, Chen Guohua did not return to Zhenhua Research Institute, but wandered to the Department of Mathematics.
"Wow, Professor Chen, you finally came to see us!"
In the office of the Department of Mathematics, Bai Ronggen and Chen Shuxing were pleasantly surprised when they saw Chen Guohua walk in.
As students of Chen Guohua, Bai Ronggen and Chen Shuxing simply suffered.
Last month, I was able to take a class with Chen Guohua and learn software programming.
After finishing their studies, they were driven back to the Mathematics Department of Peking University to engage in theoretical research.
What they need to do now is to learn how to use the papers and mathematical tools that Chen Guohua used to prove the Poincaré conjecture.
There was Erdez, a math guru, next to him. If they had anything they didn’t understand, they could ask them.
The same is true for Erdez's three students, Jiang Boju, Li Jianshu and Chang Jinping.
The result was that there was no difference. The five of them studied Chen Guohua's thesis together.
At a master's level, this is simply unbelievable.
But everyone also knows very well that for Chen Shuxing and the other five, it takes a lot of time to learn those mathematical tools.
No matter what, they can only accept this reality now.
From the current point of view, Chen Shuxing is the fastest, followed by Jiang Boju, and Bai Ronggen and the others are evenly matched.
Along with the exclamations of Chen Shuxing and the other five, Erdez, Wanioc, Eugenio Karabi and others also stood up in surprise to welcome Chen Guohua's arrival.
Especially Erdesh, he really wanted to get Chen Guohua to take action on the second question of the Riemann hypothesis.
However, Chen Guohua didn't have time. He came here today just for a stroll.
After paying attention to the study progress of Chen Shuxing and Bai Ronggen, and chatting with Erdesh and the others for a while, Chen Guohua ran away.
The main reason is that both Erdesh and Vanyoco are too enthusiastic. The former is a workaholic and only wants to engage in mathematical research.
The latter wanted to get close to Chen Guohua under the guise of mathematical research.
Therefore, no matter which one it is, Chen Guohua can only stay away from it.
After all, they all need to consume a lot of Chen Guohua's time and energy, so a simple chat is enough. If he continues to stay in the office, Chen Guohua will definitely not want to go back for lunch.
After lunch, Xu Yanmou from 5341 Factory came to visit in person.
"Director Chen, long time no see. I have sent you some materials."
"Secretary Xu, welcome. I'm waiting, but I'm eager to see what's going on. Now that you're here, I'm relieved."
When Chen Guohua saw the other party coming in, he was immediately overjoyed.
Just because the other party sent over the materials for the integrated computer.
A few days ago, brother units such as Factory 107 and Factory 985 successively sent computer materials such as chips, controllers, mice, keyboards, and monitors.
These are the office equipment that Zhenhua Research Institute urgently needs.
Without them, the following software programming and mathematical modeling competitions would be nonsense.
Just like in the current software programming laboratory, everyone has already learned the theoretical knowledge.
But since there is only one computer at present, the other two computers will be returned to their brother units after Yu Min and Guo Yonghuai complete their studies.
Therefore, Zhenhua Research Institute is just waiting for these computers to carry out the next step of work.
"Haha, I hope it didn't delay your work."
Xu Yanmou laughed loudly, and Chen Guohua didn't say anything polite to him, and went straight out to inspect the materials.
Soon, with all the computer materials in place, Xue Jinquan and the others came to the software programming laboratory to help assemble it.
In this process, everyone who is not in the software programming laboratory is envious.
Just because the most valuable thing at Zhenhua Research Institute is these fifty computers.
Many people want to try computers. After all, no one has ever touched one.
Just when Chen Guohua led everyone to start assembling the computer, Qiu Zongyue also came.
"Hey, have you got all the materials?"
Looking at the busy people, Qiu Zongyue said jokingly with a smile.
"Boss, please come here and do me a favor. Don't stand there. In the future, your office will also have to install such a computer, and you must learn how to use it."
Seeing Qiu Zongyue walking in with his hands behind his back, Chen Guohua ordered him unceremoniously.
The former's eyes widened instantly, "Do I need to use this thing in my office? I don't know how to use it!"
Wouldn't it be a waste to give such a high-end thing to him?
But Chen Guohua looked very serious and said:
"I'm definitely not asking you to learn how to program. In the future, I'm going to ask you to learn how to use a computer. There are only two points. One is to learn to control the mouse, and the other is to learn to use typing."
Zhenhua Research Institute has begun to develop aluminum gallium arsenide semiconductor lasers and chemical phase deposition equipment.
These things are equipment for developing optical fiber communication technology.
After these technologies mature, we can improve the manufacturing equipment for optical fiber production and directly ask our brother units to help with production.
Anyway, optical fibers are mainly made of silica, quartz and other materials. The refractive index of the core and multi-component glass fiber is controlled by doping the refractive index of the multi-component glass fiber, and the refractive index can be reduced by cladding.
Once the technical problems of optical fiber are solved, communication optical cables can be established.
After the communication optical cable is established, it will be easy to develop relevant communication applications on the computer.
For such a promotion plan, Chen Guohua has already been confident.
Of course, there are also optical modems, optical terminals, optical fiber transceivers, optical switches, etc. These are all problems that must be solved in optical fiber communication technology.
"Then I definitely can't learn it, no, no, no"
Upon hearing this, Qiu Zongyue shook his head and said.
His expression was extremely unconfident.
In fact, he really didn't have much confidence to do it.
If it's a mouse, then he might still have a little confidence, but if it's a keyboard, he'll feel dizzy just looking at it.
When Chen Guohua heard this, he did not continue to persuade him, but he still aroused the other party.
Anyway, it's definitely no problem to do a simple hands-on job.
Whoever let him come into the laboratory, it would be unjustifiable if he didn't help.
"By the way, leader, what's the matter with you coming here today?"
Chen Guohua asked casually while he was busy.
The boss comes here every now and then. Sometimes he has something to do, and occasionally he just comes over to take a look.
Therefore, Chen Guohua is still not sure whether the other party is okay or not.
"Didn't you ask me to apply for 10 million yuan for you before? The higher-ups approved it."
Hearing this, Chen Guohua was stunned.
Even Xue Jinquan and the others stopped what they were doing and looked at Qiu Zongyue in surprise.
Good guy, is it really worth another 10 million?
Didn’t it say it was not approved?
Why did you give it to me again now?
Chen Guohua was also quite surprised, but what he said next was not suitable for Xue Jinquan and the others to hear.
So, Chen Guohua and Qiu Zongyue left.
The computer assembly work was left to Xue Jinquan and others.
Back in the office, not long after the two sat down, Chen Guohua quickly learned the ins and outs of the matter.
In fact, it is very simple, and it has a lot to do with the medical accelerator that Chen Guohua recently brought out.
Among the leaders, several are elderly, almost seventy years old.
There are already many high-risk diseases in this age group, among which diseases like cancer are very common.
But the medical accelerator that Chen Guohua brought out can actually be used to treat cancer.
The leaders who heard the news, especially those who were already suffering from cancer, all supported Chen Guohua overwhelmingly.
In addition to this matter, there is also the situation overseas.
The latest news from China Resources is that IBM has ordered another 500,000 50-micron transistors and made a request.
That is to ask China Resources whether it can design a chip that can have two hundred transistors built into a chip the size of a fingernail?
If so, then IBM is willing to pay a high price to purchase it.
They really want to use China Resources’ technology for free.
As we all know, fifty-micron transistors are very, very small. There are more than two hundred chips built into a chip the size of a fingernail, and there are no problems at all.
There is even a lot of space.
The key is that this kind of technology has a very high degree of difficulty.
Why?
Transistors, which are half as thin as a human hair, are arranged in sequence and built into the chip.
Even the most powerful chip engineer in North America has a hard time doing it.
Just because today in North America, Tokyo, Europe, Moscow and other places, they still use masking lithography.
This method, or this technology, is very backward.
The most important thing is that its cost is very high, just because the mask is in direct contact with the photoresist coating, and then illuminated to complete the exposure.
The failure rate and cost of this lighting method are very high, because the colloid itself and the adhering dust particles not only affect the photolithography effect, but also cause pollution and damage to the photomask.
And the damage effect will accumulate with the number of photolithography times, which not only makes the yield rate of each photolithography low, but often only one of ten chips can be used.
Such a huge cost is one of the reasons why IBM placed another order.
A chip that cannot be used is waste.
Yields were so low and one of the reasons computers were so expensive.
In fact, IBM President Watson Jr. did not want China Resources to make this money, but in the face of companies such as Cray Corporation and Ector Mochley Computer Company competing for market orders, they had no choice but to do this. What a bad idea.
In Watson's view, since China Resources can develop 50-micron transistors, they even speculate that China Resources has developed smaller-sized transistors.
Then it should be possible to solve the chip technology problem.
The concept of integrated computers had already appeared in 1958.
It's already 1961, and Watson doesn't think China Resources doesn't know these things.
Moreover, Little Watson also learned from the North American intelligence agency that the mainland already has computers with millions of operations.
If the mainland has not yet developed chip technology, Watson Jr. will not believe it.
"So how much are they willing to pay?"
After listening to Qiu Zongyue's words, Chen Guohua suddenly became interested.
Although he was not interested in masked lithography, he would definitely try to improve it in order to make money.
As for using ion implantation equipment, photolithography machines and other projection lithography technologies to manufacture chips, Chen Guohua is not that stupid.
Do you really think that someone is a fool and can’t see the difference between the two?
Chen Guohua didn't want to leave any flaws to the other party.
In the history of the original time and space, projection lithography began to be developed in 1967 and only appeared in 1974.
Therefore, Chen Guohua will not take the initiative to disclose such technology.
Even if it is a finished chip, he will not give it to the other party.
"If it is a chip with two hundred transistors built in and it passes their series of tests, then it can be priced at US$10,000 a piece."
After hearing Qiu Zongyue's words, Chen Guohua suddenly sneered:
"Let them eat shit."
With just this little money, do you still want him to invest time and energy?
Then we might as well just produce transistors.
If it costs 30,000 yuan a piece, they can purchase thousands if they are exhausted.
Just thousands of chips, which is 30 million . dollars.
But with 500,000 transistors, the income is 50 million.
It is clear at a glance which of the two earns more money.
"Ah? Thirty thousand dollars a piece, you don't want to?"
Qiu Zongyue was speechless, Chen Guohua rolled his eyes and said:
"Boss, if a transistor costs one hundred US dollars and a chip with two hundred transistors is built in, it should cost US$20,000. We can still earn US$10,000. That's right."
"But leader, have you forgotten that we still need to invest time and effort, and there is a high probability that only a few chip engineers from our Zhenhua Research Institute can manufacture the chip."
"The profit of less than 10,000 US dollars is definitely not worth it."
“To make this money, it’s better to make money directly from transistors.”
Upon hearing this, Qiu Zongyue asked directly, "Aren't you afraid that they will develop a fifty-micron transistor?"
"Then I'll lower the price!"
What an old man!
Hearing Chen Guohua's answer without hesitation, Qiu Zongyue didn't know how to respond.
If you think about it carefully, this is really the case.
This was done before when selling 100-micron transistors, and the price is still the same as before, unchanged.
Therefore, once prices are reduced, it will indeed be a devastating blow to semiconductor companies in North America, Tokyo, Europe and other places.
Originally, now they are already struggling to survive in the cracks.
Just like Fairchild Semiconductor, they are still gritting their teeth and struggling to hold on. It is unclear how long they can hold on.
In fact, Cray Corporation had previously consulted Fairchild Semiconductor about whether to sell it or not.
As a result, the Eight Rebels, led by Noyce, "regarded money as dirt" and spoke sharply, rejecting Cray Company without mercy.
He didn't even give the latter a chance to make a quote, so he kicked him out.
Now Fairchild Semiconductor is at a loss when facing a more complex industry situation.
The main reason is that they have not yet improved their chip manufacturing technology and cannot reduce costs.
If the cost cannot be reduced, it will undoubtedly be a fantasy to use chips to make money.
Faced with the price proposed by China Resources for a 50-micron transistor with a starting price of 100,000 and US$250, Fairchild Semiconductor said: It’s too expensive!
They are not Texas Instruments and Cray, which have capital support behind them, nor are they IBM, an industry giant. Their shareholders are all poor.
The only shareholder that still looks like it has money, the previous optical camera company, doesn't have much money now.
In short, today's Fairchild Semiconductor is a mess!
Uncertain future!
Therefore, the wave of 'price cuts' proposed by China Resources last year were actually forcing those small companies to withdraw from the semiconductor market.
Large companies can either become customers of China Resources, or they can only bite the bullet and continue to spend heavily on research and development.
However, unless they hold back a big move, they will not be able to stop China Resources' next move.
Should research and development on transistor shrinking technology continue?
From a perceptual level, for the sake of the country and in order not to be choked, continuing research and development is the path we must stick to.
But from a rational perspective, in terms of business behavior, although most of the profits are harvested by China Resources, their technology is awesome. Once they come up with fifty micron or thirty, twenty, or even five or one micron transistors, , maybe China Resources will come up with it earlier.
Just because they reduced the price of 100-micron transistors in February last year, paving the way for the sales of 50-micron transistors.
From February last year to January now, eleven months have passed.
Capital companies such as IBM, Cray, and Texas Instruments are not fools. They must all know that China Resources has come up with better products. Now, IBM's Watson Jr. has taken the lead in asking China Resources to help produce a chip with 200 built-in transistors.
In fact, it is a test!
"Then we really reject each other?"
Qiu Zongyue tentatively asked Chen Guohua, but the latter shook his head:
"You can't make money if you don't want it, you bastard!"
"Since the other party has taken the initiative to let us kill his big fat sheep, wouldn't it be stupid to just let the other party go?"
"We might as well offer a high price first, such as one hundred thousand dollars for a chip, to test the other party first."
hiss!
As soon as these words came out, Qiu Zongyue took a deep breath.
"Are you serious?"
Chen Guohua suddenly shook his head and said:
"No, one hundred thousand yuan is still too much of a loss."
Qiu Zongyue's eyes widened even more, good guy, one hundred thousand US dollars for a chip, you still feel like you're at a loss?
"Eighty thousand dollars each, starting from 1,000 pieces!"
After thinking about it, Chen Guohua made this quote.
At the same time he continued:
"We still need to ask China Resources to always pay attention to the situation in North America. The price of computers there must be very expensive. We have to calculate the profit of the other party through their quotations."
"We want to take the majority of the profits and let IBM and others do the work for us."
Qiu Zongyue not only admires Chen Guohua's "bold" idea, but also admires him.
Confident and bold, but never blind.
But Qiu Zongyue is still worried, that is, are IBM and the others really willing to be slaughtered by China Resources?
After hearing Qiu Zongyue's words, Chen Guohua smiled slightly and said:
"We are not afraid of each other's technological breakthroughs, because we can now produce chips with two thousand transistors built in. In the first half of this year, or no later than September in the second half of the year, we will definitely be able to produce chips with one hundred thousand transistors built in." .”
"Whether it's Cray, Fairchild Semiconductor, or even their industry leader, IBM, I don't care how powerful they are, they are not as powerful as us anyway."
"So, leader, you ask China Resources to boldly negotiate prices with them and have a tougher attitude. We have been bullied by them for so many years, and we should recover some interest first."
In fact, this point in time is the best time for China Resources to develop.
The main thing is that in the mainland now, we don’t rely on anyone, we only rely on ourselves.
Kennedy certainly did not dare to push the capital too hard, otherwise, the mainland would once again lean towards Moscow.
In fact, not only would Kennedy not force China, he would even be willing to establish an alliance with the capital if a dialogue channel could be established.
As we all know, the livestock industry in North America is very developed.
As a cowboy, Kennedy was also good at herding.
For example, Kennedy established many livestock farms in Seoul, Tokyo, Siam and other areas and bred many shepherd dogs.
If Kennedy could really come to the capital, then it would be Helu who would have trouble sleeping.
Because of this, faced with China Resources Corporation's continuous efforts to earn so many US dollars, Kennedy did not have any evil intentions.
Otherwise, China Resources would have been dealt with long ago.
Helu in Moscow is simply powerless.
Several waves of people were sent to assassinate Chen Guohua, but they failed inexplicably.
We don’t even know the reason yet, so how can we talk about anything else?
After listening to Chen Guohua's analysis, Qiu Zongyue also felt that this statement was reasonable.
In this case, let's report it to the superiors first, and then talk to China Resources about the matter.
After watching Qiu Zongyue leave, Chen Guohua smiled happily.
Once the money problem is solved, you can then develop well.
This year is 61, which means the hardest year is coming.
However, in fact, compared with the original time and space, it is much better now.
The main reason is that the small wings of Chen Guohua, an Amazon butterfly, directly led to changes in many places.
As long as 1961 has passed, the days to come will slowly get better.
At the very least, so many people will no longer suffer because of eating.
The software programming laboratory, with fifty computers, was quickly assembled.
But there is no way to start all the machines at once for testing. We can only do it ten machines at a time.
After all, the power plant has not been completely built yet, and power supply is still a big problem.
Chen Guohua took a closer look and found that there are still many problems that need to be solved this year.
One is the problem of software programming, the second is the problem of electricity, the third is the problem of optical fiber, etc.!
It can almost be said that every item is an issue that needs to be solved urgently and cannot be delayed.
In the next few days, the fifty computers in the software programming laboratory have completed testing one after another.
After all computers could operate normally, Chen Guohua called everyone over.
"Okay, from now on, software programming will officially start."
Yao Shiqiong and others all listened attentively to Chen Guohua's speech.
Programming is not a very simple thing, it can even be said to be very, very difficult.
Just learning the programming language is already the biggest problem.
The current programming languages are all Chinese, not English.
As the oldest language, Chinese is also very convenient for software programming.
Chen Guohua designed a programming language called Pangu based on existing computer memory and other conditions.
It is very concise and concise, occupying only about 500,000 bytes of memory.
Each of the current 500,000 computers has only about megabytes of memory, which is not a large amount of memory.
However, with the breakthrough of chip technology, it will definitely be updated by then.
Don’t expect any updates within the first half of this year.
"As a training work for you, I hope that each of you can learn programming, and then start editing programs after learning the programming language Pangu."
Looking at the people in the audience, Chen Guohua talked eloquently:
"This project will be handed over to Comrade Yao Shiqiong. If you encounter anything you don't understand, you can figure it out for yourself as soon as possible."
"I really don't understand. If she can't make up her mind after consulting her again, then come to me."
"However, I don't want everyone to come to me. I hope everyone can learn these things by themselves."
At this time, someone asked, what if there is a problem with the system due to programming, or even the system crashes and the chip is burned?
Chen Guohua couldn't help laughing when he heard this question:
"This system is at most about 500,000 bytes, and the computer is only megabytes. Do you think a system crash will cause the chip to burn out?"
"Don't ask questions like this next time. And if you really encounter such a phenomenon, then I really need to reflect on what you have done."
Previous computer system programs were three megabytes, and that was because that computer had more memory.
It's not necessary now, so I'll simplify it.
The main issue is demand, half a million bytes is enough.
After coming out of the software programming laboratory, Chen Guohua suddenly felt relaxed.
Finally, I no longer have to be a coder in this life.
However, just as he breathed a sigh of relief, someone came looking for him from the optical instrument laboratory.
"What's wrong?"
Su Yuanfu and Gu Yuzhen came over, and Chen Guohua immediately stopped smiling.
Gu Yuzhen and the two followed Chen Guohua into the laboratory. As they walked, they talked about a problem with the spectrometer.
At this time, the optical instrument laboratory had several small groups studying different optical instruments.
For example, the small group Gu Yuzhen and his team were in at this time were conducting research on spectrometers.
As we all know, a spectrometer is a device used to measure the intensity of spectral lines at different wavelength positions through a photodetector. It is a scientific instrument used to decompose light with complex components into spectral lines.
This thing is very useful for manufacturing light sources for lithography machines.
You must know that the light sources used by lithography machines are high-pressure mercury lamps, xenon lamps or lasers, which can produce high-brightness, high-quality ultraviolet or visible light beams.
Chips are manufactured based on the differences in wavelength and power of different light sources.
In the process of adjusting this wavelength, a spectrometer is needed.
In fact, there are many optical instrument factories in the mainland, such as the Northwest Optical Instrument Factory, the Modu Optical Instrument Factory, which was only established in 1958, and the Beijing Optical Instrument Factory, etc.
But none of them had the strength to produce the spectrometer needed by Zhenhua Research Institute.
"I have talked about this photoelectric reading spectrometer before. It consists of six major parts."
"What you are developing now is a condensing device, which is composed of a condensing mirror system."
"Such systems require full utilization of the light radiation emitted by the light source to obtain large light intensity."
"So, do we use the single lens imaging method, the three-lens intermediate imaging method and the cylindrical lens imaging method to make the light emitted by the light source image on the collimating lens?"
"Technology is not difficult, but you guys!"
Chen Guohua looked at Su Yuanfu, Gu Yuzhen and others and sighed.
After explaining the technical difficulties to them, Chen Guohua was stopped by others.
It's about the development of a one-megapixel camera.
It was another technical problem. Chen Guohua had no choice but to do it himself.
"Stop, stop, why don't you use a photolithography machine to make this lens?"
After knowing the problem, Chen Guohua suddenly became anxious.
Upon hearing his words, Tao Yanqiao and the others were dumbfounded: "Director, can the photolithography machine still make lenses?"
Don't blame them for being ignorant, because they didn't know about this at all when they were at the Materials Research Institute.
In September of the previous year, when Chen Guohua left the Institute of Materials Science and Technology, the lithography machine had not yet been manufactured.
It was only after Tao Yanqiao and the others came to Zhenhua Research Institute that they learned that a photolithography machine had been developed.
But even if it was developed, they only knew that photolithography machines could make chips, but they had never heard that they could make lenses.
Good guy!
Chen Guohua was immediately stopped by the question. He didn't seem to blame them for this question.
As we all know, the application fields of photolithography machines are very wide.
Needless to say, lithography machines play a very important role in chips in the semiconductor field.
However, photolithography machines can also be used in the fields of optical communications and optical fiber transmission.
Because lithography machines can manufacture optical components and optical chips required in the field of optical communications, such as lasers, photodetectors, optical amplifiers and optical waveguides.
These components are widely used in optical communication equipment and optical fiber transmission systems.
"Director, we really don't know!"
At this moment, Tao Yanqiao, Nie Jingzhong, Gao Yumin and others were all dumbfounded.
It's quite aggrieved, they really don't know.
Seeing each of them looking eager to learn, Chen Guohua could only clapped his hands.
"Everyone is welcome. This afternoon's test will be cancelled. Let's all go to the big classroom. I will give you a popular science course in the afternoon."
When everyone heard this, they immediately cheered.
They didn't understand anything very well. Chen Guohua had no choice but to learn more about science.
Otherwise, they are all in the same research institute, and these research works are all related to each other. As a result, it seems that they have been inseparable from each other for a long time, and no one understands these things.
Therefore, Chen Guohua felt that it was very necessary to popularize science for them first.
So during lunch time, almost all relevant laboratories were called to the large classroom for classes.
Of course, there is no need for laboratory personnel such as software programming, generator sets and transmission equipment, and carbon fiber materials to go there.
Just because their research work does not involve photolithography machines.
"Old Chen, you are so pressed for time, how can you have time to teach us in the afternoon? Just write a handout for us."
During lunch time, Xue Jinquan and Lu Zijing sat in front of Chen Guohua, taking big bites of their rice and talking while devouring it.
Now their twelve super academic gods are in full-time status.
Especially after a while, they will have their final exams, and it won't matter whether they go back to school or not.
Anyway, they have all taken the final exams, and now it can be said that they are on winter vacation.
It's nothing to them during the winter vacation, they must stay in the capital.
Work is more important now, and if I want to go back, I will go back to my hometown during the summer vacation or other times.
"Haha, I gave out the handout, but you can't even look at it."
Chen Guohua smiled and said:
"Although my time is tight, as long as it is work-related and can reduce my working time, I think it is very necessary."
Hearing what he said, Xue Jinquan and the others shook their heads.
In a class, there are always students who do well in exams and students who do poorly in exams.
And Xue Jinquan and the others are the group of people who did well in the exam. Of course, they are just talking about professional courses.
For example, Xue Jinquan has always been at the bottom or at the bottom of his ideological and moral education courses.
It's not that his brain is weak, nor is there a problem with his thinking. It's just that this guy has a problem with his understanding of the course of ideological and moral character.
However, it doesn't matter. Xue Jinquan has applied to graduate early. Anyway, he has saved enough papers in the past year.
Director Xu Xianyu said that as long as he publishes more than five papers, he can apply for early graduation.
The quality of papers that can be published in journals is not bad.
With this requirement, Wan Qingxuan and the others have no chance.
But Lu Zijing, Zhang Jichuan, Zhao Jusheng and others have basically completed it, just like Yao Shiqiong and Gu Xiaofeng. The two of them directly produced ten papers.
In the afternoon, inside the large classroom.
Chen Guohua looked at the large group of people below and talked.
"In the morning, I was in the optical instrument laboratory, and when a researcher asked me about lenses, I realized that many people don't know that lenses can be manufactured with photolithography machines."
"Let me ask you a question, do you think that photolithography machines can only make chips?"
A bunch of people below all started talking loudly.
"If you answer yes, please raise your hands and let me see how many fools there are."
Swish!
Everyone originally wanted to raise their hands, but they were so frightened by Chen Guohua's words that they stopped raising their hands.
Wan Qingxuan, Liu Yongfen and other lesbians said a few words of blame.
In response, Chen Guohua just pressed his hand down, and after the classroom became quiet again, he said:
"You guys, I usually ask you to think more, but you just don't listen."
"The photolithography machine is such a useful device, it has complete functions, and there are many other devices that complement each other, but in the end, you treat it as an ordinary device."
"Listen carefully to me for the rest and remember it."
In fact, the application fields of photolithography machines are indeed very wide.
In the field of optical equipment and instruments, photolithography machines can manufacture various types of optical components, such as lenses, diffraction gratings, photoresists, filters, etc.
These devices are used in optical instruments such as laser equipment, optical microscopes, spectrometers and cameras.
In other words, with the photolithography machine, it is simply a blessing for many optical instrument manufacturers.
Regardless of the Northwest Optical Instrument Factory or the Beijing Optical Instrument Factory, they definitely need such a photolithography machine because it is so handy.
However, Zhenhua Research Institute does not produce photolithography machines, but 985 Factory and other sister units will produce them.
Even so, the manufacturing cost of a photolithography machine itself is not low. Similar to Northwest Optical Instrument Factory, they can't even pay wages. Where can they still have money to purchase photolithography machines?
In addition to these optical instrument factories, major camera factories also need photolithography machines to manufacture better optical components.
However, they may consider cost factors and may choose to purchase optical components from other brother units.
In addition, lithography machines can also manufacture microfluidic chips, biochips, drug screening platforms and other biochips for research and diagnosis.
As well as other fields such as optical memory, flat-panel displays, solar cells, and LED lighting.
These areas alone are enough to prove the power of photolithography machines.
Wan Qingxuan, Gao Guiqin, Wang Yuzhu and others all looked at Chen Guohua with dumbfounded eyes. What is a biochip? Solar battery?
And what is optical memory? What is the difference between it and computer memory?
"Director Chen, can you expand on these high-tech products?"
