One Thousand Three Hundred and Twelve Out of the Encirclement

Speaking of the chips used in our current computers and mobile phones, they were all silicon transistors that were first manufactured by the Americans in 1946 in the last century, and chips were made with transistors after that.

To put it bluntly, the principle is to put more silicon transistors on a high-purity silicon substrate, let electrons travel through these transistors, and use the unique binary system 01 language to control the switch, and finally let the chip execute purpose of the task.

To put it bluntly, a carbon-based chip is to replace silicon with carbon.

In fact, as early as the last century, someone had proposed this idea and conducted experiments.

But people at that time did not discover graphene, but simply wanted to replace silicon atoms with carbon atoms.

As a result, it was later discovered that the atoms connected by carbon and carbon were not as stable as silicon atoms in structure, and no one continued to conduct research on carbon-based chips.

In this case, until 2004, two University of Manchester professors discovered and tore off a large sheet of graphene from graphite for the first time, and won the Nobel Prize for it.

The idea of ​​carbon nanotube chips was brought up again.

Because people found that with the continuous deepening of human research on chips, Moore's Law, which originally defined the field of electronics, is no longer valid.

The original Moore's Law said that every 12-24 months, the efficiency of human research and development of electronic chips will double.

But after the chip manufacturing process enters 14 nanometers, this law has already begun to fail.

It has been found that as silicon nanotubes become smaller and smaller, it becomes more and more difficult to upgrade the next generation.

As a result, it will take about three years for humans to upgrade silicon chips from 7nm to 5nm.

And the next step from 5nm to 3nm or 2nm may take three or five years.

It may even take ten years to finally enter 1nm.

And after really mastering 1nm technology, if you want to upgrade, the physical properties of silicon transistors have reached their limits.

So in recent years, scientists have been looking for suitable materials that can replace silicon transistors.

After the British professor discovered graphene in 2004,

The theory of carbon nanotube chips has begun to spread.

The Americans are the first to carry out research. For example, at MIT, a large amount of research funding is poured into this field every year.

Until 2019, they finally successfully prepared the first carbon nanotube chip.

However, my country's research in this area is still relatively slow at present, and it is definitely not a little bit worse than that of the United States.

Just because she knew the current domestic research progress on carbon nanotubes, Fang Zilu rejected the subordinate engineers at the scientific research conference organized by the company before, and proposed the idea of ​​carbon nanotube research and development.

Because that's a complete gamble.

As an expert in hardware, Fang Zilu really understands the difficulty of carbon nanotube research and development.

Let’s not talk about carbon-based wafers for now, let’s talk about the preparation of carbon nanotubes, which is currently the biggest obstacle that plagues scientists all over the world.

Even Americans, who are the leaders in this field, can only burn money crazily to get enough carbon nanotubes.

This is still a situation where people have deep pockets and can afford to burn it. If they operate in this way, I am afraid that Company H will have to be burned down.

And they don't have the time.

Now regarding carbon nanotube chips, there are mainly several problems in the preparation.

The first is the preparation of carbon nanotubes. We all know that graphite is formed by stacking layers of graphene.

And when we roll up a single layer of graphene, it becomes a carbon nanotube.

However, after the carbon nanotubes are rolled up, they are of different lengths and thicknesses. Some of these carbon nanotubes are semiconductors, and some are conductors.

As far as carbon nanochips are concerned, what is needed is semiconductors, so how do you purify these carbon nanotubes?

You must know that if you want to reach the semiconductor manufacturing process level, the semiconductor purity of such a pile of carbon nanotubes must reach four nines after the decimal point.

The second problem is how to ensure that the carbon nanotubes are aligned in the same direction.

If you can't keep the carbon nanotubes aligned in the same direction, your carbon nanotransistors will be meaningless.

And the third problem is that you need to ensure the density of accumulation.

That is, in a space of one micron, you need to pile up at least 200 to 300 carbon nanotubes, and the direction of these carbon nanotubes must be consistent.

This is the first hurdle to be faced in the preparation of carbon nanochips.

Consistency of alignment, high purity and high density issues.

And these three difficulties alone have already put an end to 99.9999% of scientific research institutions, companies and universities in the world.

Next, there is the preparation of carbon-based wafers, and then the photolithography and etching of carbon-based wafers, as well as the photoresist to be used, etc.

Part of the preparation process overlaps to a large extent with the production process of silicon-based chips.

So when Fang Zilu was proposed to develop carbon-based chips, he rejected the proposal.

But now, when a living carbon and chip were placed in front of her, Fang Zilu was already stupid.

This feeling is really too sci-fi!

She couldn't believe it, so far, even the most advanced country of the United States has not been able to handle the technology, and now it has become an entity and appeared in front of her.

Especially just now, under the electron microscope, she has repeatedly confirmed that the array on the substrate is indeed layers of carbon nanotransistors.

Mr. Fang couldn't help but sighed a long time, then leaned back and sat back on the sofa.

"Really a carbon nanotube chip?"

Mr. Yu asked beside him, he didn't know much about hardware.

Especially in chip manufacturing, he also knows that chips with a few nanometers are better, but when it comes to the difference between silicon-based chips and carbon-based chips, he really doesn't know much about them.

At this time, Mr. Fang closed his eyes and nodded.

"Confirmed, it's a carbon-based chip."

"Oh? So what's the advantage of this kind of chip compared to silicon-based chips?"

Boss Fang suddenly opened his eyes, glanced at Boss Yu, and then said with a half-smile.

"If it is the same level of chips, such as 7nm chips, then the running speed of carbon nanotube chips will be 10-20 times that of silicon-based chips. This mainly depends on the purity of carbon nanotubes."

"In terms of power consumption, the energy consumption of carbon nanochips will only be 30% to 70% of that of silicon-based chips!"

"I go……"

After listening to Mr. Fang's description, Mr. Yu, who was sitting on the side, couldn't help but slap his hands excitedly.

Isn't this the chip they need most?

Prior to this, TSMC had already begun to cut off supply to them.

And in the coming year, they will no longer be able to get the top chips, although they have prepared a lot of 1010 chips for their undisclosed flagship phones.

But that's only enough for one year!

And in the year after next, if the political situation still hasn't changed, the United States will still insist on killing Company H.

On the domestic side, if there is still no breakthrough in the field of chip manufacturing, then their company H may really want to withdraw from the smartphone market.

With the increasing popularity of smart phones, Almost everyone knows that smart phones are the future and tomorrow.

Their company H had a hard time, and after more than ten years of hard work in this field, it has achieved the market position of today's group.

It would be a real pity if it was withdrawn from the market like this.

Maybe the company may never recover from a setback, just like Toshiba and Hitachi, which gradually disappeared from the sight of consumers.

It is easy to quit, but it is really difficult to get back up.

Look at Motorola back then. Before entering the era of smart phones, it was the only world giant that could compete with Nokia.

But once he entered the era of smart phones, he became the first giant to fall.

There is also Nokia, the out-and-out overlord in the field of mobile phones.

Two years ago, I was still complacent, smashing walnuts with my mobile phone.

But two years later, they were swept into the dustbin of history.

After that, they also wanted to resurrect their corpses many times and return to the smartphone market.

It's a pity that being eliminated is being eliminated. No matter how hard they try, they can't win back people's recognition of this brand.

And such a scene is now the biggest dilemma facing Company H.

Now the Americans can say that they have already used all the ultimate killer moves.

From the current point of view, especially from the perspective of hardware preparations, they really have nothing to fight back against the strangling of the Americans.

If it is about memory, screen, and other aspects, they can still find a way to solve it.

But when it comes to the main chip, they really have nothing to do.

Because there are only a few companies in the world that can produce chips.

LFK, TSMC, and Sansang, among them Teji and Sansang, all have close ties with Millikin's capital.

In other words, the real big boss behind them is actually a chaebol from the most powerful country.

As for LFK, they use ASML's lithography machine, the chip manufacturing equipment, and the big boss behind it is still the number one power.

Even domestic chip manufacturers use ASML equipment...

So wait until two years later, if at that time, they still fail to find a way to break the situation.

Then Company H will face a situation where there will be no products available. Without the main chip at that time, they will naturally have no products, let alone any market at that time.

But now suddenly at Xinghuo Technology, they discovered that this mysterious company actually has carbon nanotube chips that can completely replace or even bypass US equipment.

How could President Yu not be excited by this?

The dawn that broke through the encirclement finally appeared!

If an agreement can be reached with Xinghuo Technology, then their company H is still afraid of your number one strong G hammer? They definitely dare to fight the number one strong G man hard to the end!
