Hand rubbing nuclear fusion live in the wilderness

Chapter 405 Ten-nanometer carbon-based chip
The live broadcast room was very lively, Han Yuan sat in the computer room and watched the barrage.

This kind of super live broadcast room with tens of millions of people, unless he specifically opens his mouth to guide, the content of the chats in it is rarely unified.
Sometimes I was still arguing about this content one second, and jumped to another topic because of a certain sentence in the barrage the next second.

Netizens are all goldfish, and their memory is only seven seconds.

No, I was still discussing whether his live broadcast of carbon-based chip technology is good or bad for Huaguo, but now it has turned to whether carbon-based chip technology can bypass the lithography machine.

The public says that the public is reasonable, and the mother-in-law says that the mother-in-law is reasonable, and the two sides are short of reality.

In addition, there is a group of people who are not too serious to watch the excitement, and are all kinds of firefighters or selling peanuts and melon seeds mineral water.

Of course, in addition to these, there is still a part that is asking him for the 'truth' and asking him to explain.

Looking at these bullet screens, Han Yuan thought for a while and said, "Carbon-based chips also need a lithography machine, and the more top-level chips, the higher the demand for lithography."

As soon as these words came out, most of the audience immediately exploded.

【I just said I need it! 】

[Carbon-based chips also need a photolithography machine?Didn't you say that you can use some kind of laser method to deal with it? 】

[If we also need chips, we have no advantage. The top lithography machines are all in the hands of foreign countries. 】

[We have worked with Europe on the Galileo navigation system before, and we paid a lot of money. You should know what happened later, even after paying the money, let alone things like lithography machines. Our people participated in the research and development So what, if they don't sell it, they won't sell it, so I can only rely on myself. 】

[Don’t panic, the key point is that the performance of carbon-based chips is better than that of silicon-based chips. If a chip has the performance of a silicon-based chip at 10 nanometers, then a carbon-based chip only needs to be 100 nanometers, and a 100-nanometer lithography machine, We can already make it ourselves. 】

[I am an employee of a microelectronics company. Last year, our company manufactured a 15-nanometer overall lithography machine, all of which use domestic technology. 】

【Brilliant! 】

[Come and do the math, how many nanometer silicon-based chips are the performance of a 15-nanometer carbon-based chip. 】

[Conservative estimate is 1.5 nanometers ╰(￣ω￣o)]

[The problem is that we still don’t have a top-level lithography machine. Even if we can produce 15nm, but the small island country and the windmill country can produce 3nm, there is still a big gap between them. It’s better not to broadcast carbon-based chips Technology, so that we can develop it slowly by ourselves. 】

[Upstairs is correct!The chip gap still exists, so there is still a gap in the performance of mobile phones and computers. 】

[ε=(ο｀*))) Well, it would be great if this anchor didn’t live broadcast the technology of carbon-based chips, or live broadcast the top-level lithography machine, what we lack is the lithography machine, not the chip . 】

[Can the anchor broadcast live the top lithography machine, don't make carbon-based chips for now. 】

[The anchor made a lithography machine last time, and it is estimated that it will be upgraded this time, but I don’t know how accurate it is. 】

As soon as the Korean won words came out, the live broadcast room suddenly became chaotic.

Since carbon-based chips, like silicon-based chips, also require a lithography machine, even if the carbon-based chips are live broadcasted as a whole, the country has successfully produced them, and the accuracy will inevitably still lag behind.

But the accuracy is lagging behind, and the performance doesn't have to be thought about, it must be lagging behind.

In particular, carbon-based chips hardly need to consider problems such as the electron shuttle effect, which can improve the performance of the chip to a higher level.

In this way, the gap between five nanometers and fifteen nanometers between carbon-based chips is much larger than that of silicon-based chips.

After figuring this out, many viewers in the live broadcast room had some opinions in their hearts, thinking that the Korean Won's live broadcast of the carbon-based chip technology is convenient for Western countries.

Some viewers also sent barrages, hoping that he could broadcast the top-level lithography machine technology first, and then broadcast carbon-based chips.

Han Yuan didn't care about these barrages.

He knew that the audience in the live broadcast room regarded him as his own, that is, as a Chinese from the parallel world.

Coupled with other factors such as patriotism, it is naturally understandable for him to broadcast the top lithography machine first.

After all, except for 50 and 1450, no one would not want their motherland to be stronger.

In the computer room, the backup of related programs is still in progress, Han Yuan looked at the virtual screen and said:
"Carbon-based chips require corresponding lithography machines and photoresists and other equipment. The equipment and materials used are somewhat different from the previous silicon-based integrated chips."

"So before making the chip, I still need to upgrade the original lithography machine as a whole, and then I can process it."

"Beyond that, there are the most critical 'carbon' materials that need to be produced, such as graphene, silicon carbide, carbon nanotubes, and more."

"These different materials require different production methods, and they need to be prioritized because of their relationship to the main raw materials for producing carbon-based chips."

After a pause, Han Yuan glanced at the program and database being copied, and then said: "After the data backup of the integrated chip computer is completed, you can start processing the carbon-based chip."

"It will take about one to two days to copy the data."

Before Han Yuan finished speaking, the audience in the live broadcast room couldn't listen anymore, and asked questions one after another.

[Wonderful! 】

[Well, I just said, this time the lithography machine will definitely be upgraded, so why not worry. 】

[With a lithography machine, everything is easy to say, as long as it can be leveled, I believe that with our country's production capacity, we can break through the bottom line of the chip industry's price! 】

[Accuracy, precision, precision, the important thing is said three times, the precision of the lithography machine is the key, if it is upgraded from the millimeter level to the micron level, what is the use? 】

[Yes, the accuracy of the lithography machine is the key issue. 】

[Anchor anchor, what is the accuracy of your upgraded lithography machine this time, don’t just upgrade from millimeters to microns. 】

[It is best to use a one-nanometer technology, which can directly smash through the bottom line of the chip. 】

[One nanometer is unlikely, two or three nanometers or four or five nanometers can be a dream, ten nanometers can look up, I personally estimate that the progress may be around [-] nanometers, after all, the previous chips are all millimeter-scale, no matter what It is also impossible to upgrade in such a large span at once. 】

[I hope the precision can be higher. I don’t expect one nanometer, but I’m satisfied if it can be around ten nanometers or less. 】

I got an answer from Won that the lithography opportunity should be upgraded, and the netizens in the live broadcast room were concerned about the accuracy of the lithography machine.

After all, this can be regarded as a lesson learned.

When KRW made a lithography machine for the first time, the audience in the live broadcast room were very excited, but then they were poured cold water.

The precision of the lithography machine he made is at the 'millimeter' level.

This makes most people very disappointed. Although there are some spare parts in the millimeter-level lithography machine that can be used at the nano-level, it is still at the millimeter level.

So this time the audience was a little nervous, not sure how accurate the upgraded lithography machine could be.

Not only ordinary viewers are concerned about the accuracy of the upgraded lithography machine, but the governments of various countries and lithography machine-related companies squatting in the live broadcast room are more concerned about this.

Because of the next issue of accuracy, it involves changes in the situation of the entire world.

For the upgrade of lithography machines, Huaguo does not have much opinion.

It would be a huge surprise if the precision could be improved to the nanometer level.

If the accuracy is not improved to the nanometer level, it doesn't matter too much.

What Huaguo pays more attention to is not the specific accuracy, but the various new technologies revealed during this upgrade process.

As long as it can be applied to other aspects or can improve the precision of domestic lithography machines, it is enough.

Compared with other small countries, Huaguo now pays more attention to learning new technologies from the live broadcast room, and then applying them, rather than simply copying them, because of the hints of the Korean won.

Although the accuracy of domestic lithography machines is indeed several levels behind, as long as you invest in research and development and learn from experience, it will be a matter of time to catch up or even surpass it.

Hua Guo has this confidence.

Relatively speaking, Western countries that have mastered top-level lithography machine technology are much more disturbed.

If the accuracy is at the micron level or around one hundred nanometers, Western countries are completely acceptable.

In other words, as long as the accuracy is not lower than ten nanometers, Western countries can accept it.

After all, when it comes to lithography machines, they are leading the way.

Although the precision of the chips currently released on the market is basically at the five-nanometer level, it does not mean that they have no technical reserves.

In fact, chip manufacturers including AMSL and TSMC have corresponding technical reserves.

Five nanometers is not their limit, not even three nanometers.

They can get a two-nanometer chip out in a short amount of time if needed.

Of course, this is at the expense of a reduction in the yield rate of the chip.

The current two-nanometer technology is not very mature, and the electron shuttle effect is a bit serious on this level of silicon-based chips, and companies are still trying to find ways to reduce these problems.

But it is undeniable that they are still at the top in terms of chips. As long as the gap is not narrowed too much by their opponents, they are still monopolized.

After all, the chip is related to the performance of mobile phones, computers and other equipment.

But soon, the answers in the live broadcast room let them fall into disappointment.

Han Yuan looked at the barrage and said with a smile: "This time, the upgrade of the lithography machine will be carried out in two steps."

"The first upgrade will be to manufacture [-]nm silicon-based chips."

"This level of chip is the highest level I can achieve with the current integrated chip computer."

"After processing this level of chips, I will assemble the produced fifty-nanometer chips into a new computer, and then perform a second upgrade."

"The second upgrade is to manufacture ten-nanometer-scale carbon-based chips."

"This level of chip is almost the best I can make so far."

"No matter how high the accuracy is, the current equipment and the net junction laboratory cannot meet the requirements."

"However, ten nanometer carbon-based chips are enough for now."

"Because carbon-based chips have better performance than silicon-based chips."

"And this excellence is not only reflected in the speed of floating-point operations, but also in its low power consumption, high stability, ability to withstand high current, and minimal electronic shuttle effect."

【Great! 】

[Ten nanometer-scale carbon-based chips, awesome! 】

[If the nanochip with this precision is silicon-based, it may not be enough now, but if it is carbon-based, it is definitely enough! 】

[A ten-nanometer carbon-based chip can perform as well as a one-nanometer silicon-based chip, right?The performance of all carbon-based chips is more than ten times that of equivalent silicon-based chips. 】

[Almost, the current research is like this, it depends on the specifics, but it is indeed enough. 】

[But there is still a gap. Foreign AMSL can achieve 5nm level or even 3nm, 2nm level. 】

[Although the chip level is still lower than that of AMSL and TSMC, ten nanometers is already very good, at least you can produce it yourself. 】

[Looking forward, the mobile phone and computer industry will undergo a major upgrade again! 】

[Hehe, it is indeed a wise choice for me to use Xiaomi Mi 6 this year. After one or two years of use, I can directly replace it with a carbon-based mobile phone, which I think will last longer. 】

[A mobile phone, dual cameras, all three networks, four-sided curved screen, Muto blue, 6G memory, seven-year-old work, all-round prestige, long-standing reputation, I really want to buy it--out of stock!This is Mi [-]! 】

[I think Boss Lei should hate Mi 6 to death. How much money will he make with new phones in the future because of a Mi [-]? 】

[Change the membrane, change the case, and replace the battery, and my 3 can still be used for another [-] years. 】

[In 20 years, I had already bought Mi 10, but when I saw Mr. Lei’s Mi 6 press conference, I was so excited that I returned Mi 10 and continued with Mi 6. 】

[Hahahahahahahahahahahahahahahaha, the upstairs is definitely here to make trouble, Boss Lei will hate you to death. 】

As soon as the ten-nanometer-level carbon-based chip was announced, the barrage in the entire live broadcast room went up.

Some people were pleasantly surprised and some were disappointed, but this news is still within the acceptable range of the whole world.

Even the Western countries that master the lithography machine look a little ugly, and they are a little disappointed and fortunate about this result.

After all, ten-nanometer carbon-based chips are still within their expectations, although this is close to the bottom line.

It's just that everyone may have to fight the bayonet next.

In the manufacturing process of silicon-based chips, there are several thresholds.

Hundred nanometers, 45 nanometers, fourteen nanometers, ten nanometers, seven nanometers, five nanometers, etc.

These thresholds represent the technical level of manufacturing chips, which are caused by different reasons.

For example, for [-]nm chips, the threshold is the light source.

As we all know, the light source of a lithography machine is a scalpel for engraving chips, but light has a wavelength.

The wavelength of light limits how sharp the carving knife can be on this side.

For example, the wavelength of infrared light is between 770 and 622nm. Using this light to engrave chips, the accuracy obtained is almost in this wavelength range.

After reaching the [-]nm level, almost most of the light waves are ineffective, and only the extreme ultraviolet light source can barely meet the requirements.

Therefore, extreme ultraviolet light is one of the core components of top lithography machines, because it can be used to engrave chips below ten nanometers.

The audience in the live broadcast room were actually thinking wrong.

In their view, there is still a big difference between 10nm and 3nm, but in the field of lithography machines, everyone knows that the light sources used by 10nm chips and 3nm chips are actually the same. extreme ultraviolet light.

Therefore, as soon as the ten-nanometer chip technology is broadcast, the problem of the light source will definitely be solved by this anchor.

Then the top lithography machine chip manufacturers such as AMSL and TSMC do not have many remaining advantages.

It's just that this result is easier for people to accept than the anchor directly dropping a 1-nanometer chip.

After all, the light source is only a part of the lithography machine, and they still have some advantages in other areas.

However, without the advantage of the light source, the original monopoly position will be reduced, and it will be impossible to make money lying down, so the next step is to fight the bayonet.
