Hand rubbing nuclear fusion live in the wilderness

Chapter 273 The Brainless Troll

Compared with the fanaticism of the audience, the countries that watched the live broadcast and have been studying the various technologies displayed in the live broadcast of the Korean won are much calmer.

Whether it is the country of Hua, or the country of America, or the country of windmills that controls the Asmer company.

Before Won said that he would prepare a lithography machine in the next live broadcast, he had already made countless speculations and estimates on Won's technology and current industrial equipment.

Some are happy, some are disappointed.

However, after careful research, experts from various countries basically agree that it is impossible for this anchor to produce a lithography machine below the micron level at the current stage.

The reason why there is still [-]% uncertainty is because the anchor has shown many scientific miracles before.

For example, using the chemical method of "electrothermal ion infiltration" to replace the ion implanter to a certain extent is completely a dream in everyone's eyes.

Or the manufacture of 'electric propulsion-free fluid engine' is a technology that is completely in the next century.

This anchor has shown too many impossibilities, so no matter what expert, even a Nobel Prize winner, he will not say anything dead.

What if the other party uses this simple tool to rub out a nano-scale lithography machine?
Isn't that the face is swollen?
Unlike the previous electromagnetic rifle and lithium-sulfur battery, today's live broadcast received special attention as soon as it started. People from any country felt a little uneasy.

After all, no one has the previous technologies such as electromagnetic guns, lithium-sulfur batteries, and electric propulsion engines anyway. Let's start research together, it's nothing more than a matter of speed.

But the lithography machine is different. If there is a problem with this, it will completely change the world pattern.

Looking at the carnival mixed with some bullet screens about the accuracy of the lithography machine, Han Yuan sighed slightly in his heart, and replied:

"In terms of precision, the lithography machine prepared this time should be at the millimeter level, not too high."

"For me, a high-precision lithography machine is still impossible for me."

"As the leader of microelectronic equipment, there are tens of thousands of parts in a lithography machine."

"From the exposure system, to the workpiece stage mask stage system, to the automatic alignment system, to the focusing and leveling measurement system, each system has countless parts and software to cooperate."

"A top-notch lithography machine requires every system module to be top-notch in the electrical age."

"Perhaps you don't have much idea about nanoscale lithography machines. Let me give you a simple example and you will know how difficult it is to manufacture a top-level lithography machine."

"The diameter of an ordinary human hair is about 40-50 microns, and 1 micron is equal to 1000 nanometers."

"That is to say, the precision of a five-nanometer lithography machine is equivalent to one ten-thousandth of a hair."

"Such precision, if you are not under a top-level microscope, you can't see it at all, let alone use light to expose printed circuit diagrams on it."

"It's not that there are no micron-scale, nano-scale, and picometer-scale preparation technologies, but the industrial equipment in my hand is not enough to support me to prepare high-precision lithography machines."

"If there is no accident, the live broadcast will continue. In the following live broadcast, I should prepare a nanoscale or even a picometer-scale lithography machine."

One stone stirred up waves, and Han Yuan's words immediately caused waves in the live broadcast room.

【ε=(ο｀*))) Alas. 】

[I thought this time, we could do it. 】

[It's okay, I believe it won't take long. According to the current progress, it can be made in a year or two at most. 】

【That's it?I am so disappointed!Garbage, waste, even a nanoscale photolithography machine cannot be made. 】

【? ? ? ? ? 】

[What kind of trash are you upstairs?Can it be classified?Is it dry waste or wet waste?Or kitchen waste? 】

[Garbage still has the value of recycling, that's it?As soon as I opened my mouth, I knew that it was useless except wasting food, wasting oxygen and wasting land. 】

[Which mental hospital upstairs came out, so brave?Can one have a reunion dinner alone? 】

[Am I wrong?If you can't even make a lithography machine, isn't it a waste?Also millimeter level, how many millimeter level photolithography machines are there? 】

[wcnmlgb! nmsl! sbwy! nqjdsl! 】

[I'll be good, what kind of person is this, can this also be sprayed? 】

[What about the super tube?Is the super tube still out? 】

[The words are not rough, the millimeter-level lithography machine is indeed useless. 】

[Hey guys, you didn't hear what the anchor said, did you?It's not that there is no technology, it's just a conditional limitation. 】

[Hehe, a group of people lick like this?He said he has nano-level technology, do you believe it?Even if there is?Will it be produced for you to see?It’s still at the nanometer level, hehe, what the hell, if you have the ability, just make it this time. 】

[Forget it, don't talk about it, when dealing with this kind of person, everyone just scolds them directly. 】

[The mouth is so stinky, I guess you have to buy yourself poor if you buy mouthwash. 】

【Is anyone upstairs going to the hospital?If I take you there, should I go to the gynecology department or the psychiatry department first? 】

[Should be going to the pet hospital! 】

I don't know who started the group, and there was an instant curse in the live broadcast room.

It is probably the first time that tens of millions of people collectively scolded one person in one live broadcast room.

Compared with the very few brain-dead people, 90.00% of the viewers above [-] in the live broadcast room know the value of this live broadcast room in their hearts.

From the live broadcast to the present, the various black technologies revealed have shocked everyone.

Even if they can't read it a long time ago, it doesn't matter, someone can understand it.

Most people are well aware that this live broadcast room is gradually changing the whole world.

For example, the previous lithium-sulfur battery, after the emergence of lithium-sulfur battery, the major mobile phone manufacturers in Huaguo collectively announced that they would provide mobile phones with ultra-long battery life in the near future.

Or new energy vehicles, the cruising range is about to break through thousands of kilometers.

These things are rapidly infiltrating into everyone's life, quietly beginning to change.

And the most important point is that the language the anchor spoke at the beginning was the same Chinese as them.

This is guessed by most of the audience that Han Yuan may be from Huaguo in another parallel world or someone who got a golden finger.

This layer of identity naturally brings the relationship closer.

Although many viewers feel that it is cheaper for other countries to live broadcast to the whole world, it would be better if they only live broadcast like Huaguo alone or contact the above for trading technology.

It's a pity, but something is better than nothing.

What's more, many of the technologies displayed during the live broadcast by this anchor were originally backward in Huaguo.

After the live broadcast, it can quickly raise the level to the top of the world and stand on the same level as other countries.

For Huaguo, this is enough.

Moreover, ordinary people have no way of knowing whether the higher-ups have already contacted Han Yuan, maybe there is a country standing behind the other party?
Therefore, everyone has relatively maintained a tacit understanding in this live broadcast room, at least this kind of brainless phenomenon rarely occurs.

Not to mention other things, even the god of river crab would not allow someone to do this. It's really a big mess, and being invited in for tea is a sure thing.

After all, there have been people who were caught spreading a link of a certain color in this live broadcast room before.

Not to mention the anger of the netizens in the live broadcast room, even Chen Zhenghua from the special operations team was a little scared.

Judging from the behavior database established before, the other party is very familiar with Huaguo.

Regardless of whether the other party is from a parallel world, or whether the original Hua country person got an adventure, at least the other party is currently broadcasting live in Hua country.

Once the other party is unhappy because of some brain-dead crafting sticks and stops the live broadcast or changes the platform, it will be cheating.

If there is no live broadcast, at most the whole world will lose a black technology live broadcast room together, and everyone will return to the original state together.

Once changing platforms, or going abroad, it would be a big loss for Huaguo.

"Kill chickens to make an example to monkeys!"

Chen Zhenghua narrowed his eyes slightly, watching the news delivered by his subordinates.

Ordinary viewers and netizens are not this anchor, so they can't find any information at all.

All viewers who have registered on the Douyu platform can find the corresponding information in the database.

Although they have no way to use this live broadcast room, nor can they control the speeches and discussions of ordinary people in it, but this does not mean that they cannot find the audience in the live broadcast room.

In the past, when people from a country tried to communicate with this anchor through a large amount of rewards, they found them in this way, and they also caught a group of people who maliciously used this live broadcast room to spread color links and illegal content. link people.

After issuing a series of orders, Chen Zhenghua leaned back in his chair and watched the live broadcast on the computer.

It's a pity that they failed when they banned netizens from registering Douyu platform accounts two years ago.

Even if Douyu modified and republished the program, controlled the code, and deleted the code that registered the program, it was useless.

Douyu's registration page still exists and can be opened, which cannot prevent netizens from registering accounts to enter this live broadcast room.

Otherwise, Huaguo is fully capable of swiping all the current account owners once the account registration is prohibited, so as to prevent foreign people.

In the simulated space, Han Yuan didn't see the barrage.

After he finished speaking, he searched the studio for the lithography machine drawings he had drawn before, and when he looked at the barrage again, there was already a lot of scolding on it.

Although I was a little curious about what the one who was scolded said, Han Won didn't ask.

The drawings in their hands were spread out on the wooden desk, and the audience in the live broadcast room gradually stopped fighting back and turned their attention to the drawings of the lithography machine.

After laying out the structure diagram, Han Yuan said: "The photolithography machine is also called the 'mask alignment exposure machine', and it is the core equipment for the production of large-scale integrated circuits."

"Whether it is manufacturing or maintenance, a high degree of optical and electronic industrial foundation is required."

"Under the circumstances that the current industrial equipment has not been upgraded enough to support it, I can only choose to manufacture a manual-operated and semi-mechanically assisted lithography machine."

"I can use the transistor computer to assist me in controlling its exposure system and adjustment system, but the precision of manual work can be imagined not to be much higher."

"This is also the main reason why I cannot prepare a high-precision lithography machine at present."

"After the first computer using an integrated chip as the core is manufactured, I can write a control program to gradually improve the exposure accuracy of the lithography machine."

Hearing this, the audience in the live broadcast room were a little surprised.

[Manual lithography machine? 】

[Isn't the lithography machine all automatic?Manual operation, how big is the error? 】

[The most primitive lithography machine is hand-operated. From the tube computer to the transistor computer, the computer has changed from large to small, and it is inseparable from the small chip. 】

[It's hard, okay? 】

[To tell the truth, the lithography machine is the product of human involution. 】

[The lithography machine is very difficult, and what's even more outrageous is that the anchor can start manufacturing it in more than two years but less than three years. 】

[Two years is not enough time for me to make a baby. 】

[It is recommended that those who have not produced a baby for two years go to the hospital to have a look, and say that it is not you or your wife that has a problem. 】

[I feel that studying lithography machines is not as good as studying carbon-based chips. Silicon-based chips are almost at their peak anyway, and carbon-based chips can be manufactured without lithography machines. 】

【How did the two men make it?Suggest a substitution >_<]

[Experiences from people who have been here tell you that carbon-based chips are currently just a fraudulent fund. If you don’t believe me, just wait 10 years and see. I’m absolutely right! 】

[Carbon-based chips do not need a photolithography machine? 】

[Nonsense, how do you engrave and expose circuit diagrams without a lithography machine. 】

[Laser ablation method!Arc discharge method!Can be used to expose the circuit diagram of carbon-based chips! 】

There was a lot of discussion on the barrage, and the content of the chat just entered Han Yuan's eyes. When he saw the barrage on the virtual screen, a trace of surprise flashed in his eyes, and he continued casually:

"Carbon-based chips can indeed bypass lithography machines to a certain extent, but that is limited to chips above ten nanometers."

"Top-level carbon-based chips still need a photolithography machine for exposure processing."

"In the age of microelectronics, nothing is more suitable as a scalpel for carving than photons."

"Stability, reliability, and speed are all advantages of lithography machines."

When the audience said that the laser ablation method and the arc discharge method engraved and exposed the circuit diagram, Won was a little surprised.

Because it is true.

For millimeter-scale and micron-scale carbon-based chips, it is indeed a feasible way to use these two methods to prepare carbon-based chips.

This is determined by the nature of the carbon atom.

Whether carbon nanotube semiconductor materials or graphene semiconductor materials are used to prepare chips, they can be engraved by laser and electric arc to a certain extent.

The principle is nothing more than to increase the energy level of light or use the energy of the arc to etch or break down the specified circuit.

But at the level of ten nanometers, the above two methods will lose their original effect.

Although the laser ablation method also uses a light source scalpel, it uses a ruby ​​or sapphire laser, which is much higher in energy level than the ultraviolet light source used by a lithography machine.
At the nanoscale, the laser generated by the laser ablation method will directly etch through the gate and the substrate because the energy level is too large, and the arc discharge method is the same.

Both will cause large-scale irreversible damage to the gate when engraving at the nanoscale, thus directly damaging the entire chip.

These things are what Won learned from 'Information on Preparation of Carbon-Based Integrated Circuit Boards'.

At least it can be produced or what problems will occur during production have been verified by the system.

However, he still underestimated the fanaticism of the audience. After saying these words casually, the entire live broadcast room boiled again.
