There was a burst of heated discussions and sensations at the scene, and people were shocked by the words that a chip the size of a fingernail had a wire length of tens of thousands of meters.

In this regard, Lin Xuan slowly raised his hand again and made a silent movement.

The people who saw Lin Xuan's movements also closed their mouths one after another, so Lin Xuan slowly spoke:

"I think you have also learned the concept of resistance, and you know that the longer one of the wires, the greater the resistance.

Although the wires are not actually connected together, but are divided into segments, this does not prevent the fact that they are actually equivalent to one long wire.

In the past, if you were curious about why a small chip, its power can reach 65 watts, 90 watts and even 120W.

You can now cut your curiosity in half, because you only have to think about the fact that a chip the size of a fingernail has the equivalent of tens of thousands of meters of metal wire.

Then you know how big the resistance of this thing is, and where most of the heat of the chip comes from. ”

Hearing Lin Xuan's words, the people at the scene nodded one after another.

By this point, they had understood where most of the heat in the chip was coming from.

A: There is no doubt about it.

In addition to the heat emitted by the transistor when the transistor is running, the metal wire is definitely a big contributor of heat!

After all, according to their understanding, when an electric current passes through a conductor, it heats up, and at this time, just think about the tens of thousands of meters of wire in the chip the size of a tiny fingernail.

Then you know that the heat emitted by the wire equivalent to tens of thousands of meters of length cannot be ignored!

"We have previously developed cobalt interconnection technology, which is not a simple high-purity cobalt, but a special cobalt alloy.

This cobalt alloy has better thermal conductivity and lower electrical resistance than single crystal copper.

So we can use cobalt interconnect technology to make chips with more cores, and eventually we can plug more transistors to beat more advanced manufacturing processes.

But now we can sweep cobalt interconnect technology and copper interconnect technology into the history heap because we have developed carbon wire interconnect technology! ”

Hearing Lin Xuan's words, the people at the scene looked at Lin Xuan curiously.

They have just learned that the conductivity of this wire called carbon metal is second only to that of superconductors, but they don't know what the actual effect is.

Although Lin Xuan just said a bunch of professional terms, he said the parameters such as the essence of carbon metal wire, carrier mobility and maximum current carrying capacity.

But people don't understand these technical terms at all.

People want to know more about the use of carbon wires to connect the transistors of the chip without changing the manufacturing process.

In the end, how many cores can be plugged in compared to before, and how many transistors can be plugged in!

In this regard, Lin Xuan did not deliberately get stuck in his neck, but looked at people's confused eyes, and he directly skipped many links and came to the profile picture of the chip.

Product name: Hanfeng fourth-generation chip

Fabrication process, 45nm fabrication process.

Process technology: Carbon metal wire interconnection 3D chip stacking technology (5 layers) ......

Number of cores: 8 cores

Architecture: The second-generation Hanfeng intelligent architecture

Number of transistors: 3.5 billion!

Hantang Antutu CPU score 120159 points, GPU score 160673 points.

"This ......"

Looking at the parameter data of the third-generation Hanfeng chip displayed on the large projection screen, the scene fell silent.

"Am I mistaken? Are you sure there's nothing wrong with seeing a running score? 120,000 points, surpassing 42,000 points of Pingguo mobile phone, and 25,000 points of Sanxing S1 mobile phone? ”

"yes, there should be a mistake in the above, and the number of transistors on it should also be wrong.

It is an exaggeration to write 3.5 billion, it must be a mistake, it should be written 1.5 billion. ”

"That's right, Hantang Technology uses a 45-nanometer manufacturing process, and if you want to stuff 3.5 billion transistors into a chip the size of a fingernail, how can this be possible!"

"That's right, we must have read it wrong, no, it shouldn't be that we read it wrong, but the person who made this PPT wrote it wrong!" ……

There was a burst of heated discussions at the scene, and people thought that they had seen it wrong or thought that this scene was completely a spoof by the person in charge of PPT of Hantang Technology.

However, Lin Xuan said a sentence that successfully interrupted their fantasy and brought them back to reality:

"As you can see, our carbon wire has a very high intrinsic carrier mobility and the highest current carrying capacity compared to cobalt wire.

So all the same, our carbon wire generates less heat and has more conductivity and conductivity, so we can plug in more transistors without worrying about heating.

The end result is as you can see, still using the 45nm process.

In a small fingernail chip, we use 5-layer 3D chip stacking technology to stuff 3.5 billion transistors! ”

"Smack!"

In the front row of the audience, the disposable paper cup that Jobs was holding in his hand slammed onto the table in front of him.

The water splashed, just soaking Jobs's clothes in an instant.

But at this time, Jobs was still unconscious, just staring at Lin Xuan blankly, his eyes were full of disbelief!

"It can't be!"

Beside Jobs, Kuke exclaimed in surprise, and at this time he was also stunned to look at the parameters above, his eyes full of disbelief.

Beside Kuke, at this time, a man with a respectful face looked at Lin Xuan above, his eyes were full of complexity.

"3D chip stacking technology, carbon metal wire interconnection technology...... What stupid things did I do in the first place! ”

Boss Li of Sanxing Electronics looked painful at this time, and he regretted his behavior of cutting off the supply of Hanfeng generation chips at the beginning.

Because if he had continued to supply the Hanfeng generation of chips, but still OEM mobile phone chips for Hantang Technology, he would not have come to this point now!

will not release the Menglong of Hantang Technology to let him enter the field of chip production, and eventually cause the bitter fruit in front of him!

At this time, Boss Li regretted it very much, regretting why he obeyed the order of Huaer Street in the first place, instead of forcefully going back.

If he hadn't done that, Hantang Technology might not have entered the field of chip production, and Sanxing would not have competed with Hantang Technology.

It will not be like now, with the launch of terrifying 3D chip stacking technology and carbon metal wire interconnection technology, successfully defeating 14nm with 45nm...

And this is not the limit of Hantang Technology, there is even more terrible news hidden in it, which can defeat 14 nanometers using 3D chip stacking technology and carbon metal wire interconnection process.

What if the process technology of Hantang Technology is upgraded to 32nm or 28nm in the future? How will they deal with these 14nm then?

Boost 10nm or even 7nm? Can't do it!

14 nanometers has already hollowed out the old bottom of the West, and it is very difficult to enter 10 nanometers!

And the most terrifying thing is that Hantang Technology's mobile phone chip is only superimposed with 5 layers of structure, if you add one more layer or even two layers, it is equivalent to how many transistors are plugged down? !
