Hand rubbing nuclear fusion live in the wilderness

Chapter 424 Changes in the world, the country of Hua taking the lead
After recovering from his thoughts, Han Yuan unconsciously squeezed the carbon-based chip in his hand.

The pitch-black chip sandwiched between the thumb and forefinger immediately showed a small arc, like a soft card.

This immediately aroused the interest of the Korean won.

It is certain that carbon-based chips and silicon-based chips are more flexible, but what kind of flexibility can be achieved, Won is very curious.

Although he has already seen it in the "carbon-based integrated circuit board preparation information", it is not reality after all, it is just a piece of virtual knowledge information.

In the photolithography room, Han Yuan pinched the carbon-based chip in his hand, gradually increasing his strength with his thumb and index finger.

He wanted to see where the bending limit of this chip was.

As the strength of the thumb and index finger increases, the curved arc of the black chip stuck between them also becomes larger.

Finally, when the bending angle was close to thirty degrees, a crisp and weak sound came from between the fingers.

'Clap~'

The carbon-based chip finally couldn't bear the pressure, split from the middle, and shattered into two pieces.

Looking at the cracked chips that fell on the silver-white experimental table, Han Yuan was a little surprised.

Although he had seen this flexibility in the knowledge information, the actual test really made him feel a little unbelievable.

It breaks only at a bending angle close to [-] degrees, which is impossible for silicon-based chips.

However, bending at this angle, even if it is not broken, will definitely affect the internal circuit of the chip.

After all, the precision of this kind of thing is extremely high.

Picking up the broken chip from the table, Han Yuan looked at the stubble at the break.

The fracture is irregular, but there are no additional flaws in the stubble, and there is no black powder on the silver-white table.

This shows that the chip still maintains a fairly high level of self-integrity when it receives external pressure.

This is quite difficult and valuable. The properties of carbon-based chips and silicon-based chips are very different. The graphene single crystal wafer material is still carbon atoms in essence.

Although its stability is stronger than that of ordinary carbon atoms, the links between carbon atoms are still not very stable when subjected to external forces, and there will be multiple breaks.

This is a big disadvantage for a chip.

After all, no one can guarantee that the computer will not be dropped, or will not receive shocks or something.

If a chip is so fragile that it will cause problems if it is dropped, it is definitely not compliant.

It now appears that this problem has been solved on carbon-based chips.

The chip broke into two pieces neatly, and there was no residue, which is a pretty good proof.

[To waste everything, a chip with 68 billion transistors just disappeared! 】

[Waste, a chip is scrapped like this. 】

[The flexibility is pretty good, it won’t break until it’s bent like this. 】

[One of the advantages of carbon-based chips is that they are more flexible than silicon-based chips. 】

[I'm curious, how many times the performance of carbon-based chips can reach that of silicon-based chips?Are ten times the rumors on the Internet true? 】

[No matter how many times, it is certain that the end of silicon-based chips is coming. 】

[Companies such as Intel, Qualcomm, AMD, TSMC and others expressed their praise! 】

[Hahahahahaha, the upstairs is going to kill me from laughing. 】

【Grass!It suddenly occurred to me that I still had Qualcomm shares in my hands. These were estimated to be worthless, so I quickly threw them away. 】

【I have it too, but I threw it away half a month ago. 】

[The upstairs is full of rich people, and they still have money to speculate in stocks at this time. 】

I don't know who started it. When the topic in the live broadcast room spread to the stock market, everyone seemed to wake up.

With the official launch of the carbon-based chip in this live broadcast room, a fluctuation no less than a magnitude [-] earthquake spread throughout the semiconductor industry.

The official launch of the carbon-based chip, even though it was only in this live broadcast room, still had a great impact on the present world.

Leaders in the semiconductor industry such as Intel, Qualcomm, AMD, and TSMC were all red on the stock exchange, and their stock prices fell directly to the floor, making countless people want to jump off the building.

In Huaguo, whether it is A city or Hong Kong stock market, the semiconductor industry is also booming, but it makes countless people want to buy properties with joy.

The stock prices of domestic leaders in carbon-based chips such as Ziguang Guoxin, Sugon, and HiSilicon quickly climbed to the top like a roller coaster ride.

Before the data of this carbon-based chip is released, people still have a hint of luck.

But with the announcement of the number of transistors, not to mention companies such as Intel and Qualcomm, even the entire silicon-based semiconductor industry, a gigantic building with a trillion-dollar market size, is shaking, as if it will collapse in the next second.

Everyone knows that the technology in this live broadcast room can be reproduced.

Lithium-sulfur battery, electric propulsion-free engine, gallium lanthanide silicon solar thin film power generation panel, AZO transparent thin film
These things that have appeared in this live broadcast room are already close to people's daily life.

Just like in Huaguo, after two years of mobile phone upgrades, most mobile phones now use lithium-sulfur batteries and AZO transparent film displays.

Although patent fees still need to be paid, compared to before, the patent fee paid is nearly half, and the savings can be said to be a considerable sum.

Moreover, paying patent fees to the state and paying patent fees to foreign companies are completely different concepts.

As long as you are human, you know how to choose.

Everyone believes, at least Huaguo believes that, in the near future, carbon-based chips will replace silicon-based chips and enter people's lives.

In fact, it is.

Two years ago, when South Korean Won accidentally revealed that he had carbon-based chip-related technology in his hands, Huaguo's high-level executives launched related meetings and investigations.

In the end, under the suggestion and support of Chen Zhenghua, the leader of the special operations team, with enterprises such as Zhongke and Hisilicon as the leaders, an industrial chain cluster with carbon-based chips as the leading position and the development of carbon-based semiconductor materials was established in Shenzhen Stock Exchange. .

It can be said that it is a great courage, even a gamble, to divide a park covering an area of ​​[-] square meters in Shenzhen, a city where every inch of land is expensive, as the foundation of the carbon-based industrial chain.

Moreover, this is still the first phase of planning. If the follow-up progresses smoothly, the area of ​​this park will be further expanded.

Now they have won the bet. The advent of carbon-based chips will make this park flourish and Huaguo will advance at a high speed.

In the lithography room, Han Yuan checked the chip that was broken into two sections, put it into a special plastic bag, and then put away the remaining chip.

Now that the chip is manufactured, it must be inspected next.

This was a rather cumbersome step, not only the complete chip had to be inspected in detail, but even the chip he had just pinched off had to be inspected.

The first batch of these 12 yuan chips produced, won't be used to make computers or other equipment.

These chips will be used in various tests.

For example, after extreme bending, test the damage of the circuit in the chip.

Just like when he bent the chip with external force and broke it, how many transistors were damaged, how many logic circuits could not be connected normally, including how far the chip was bent, the circuits inside would not be affected, these are all to be tested.

There are hundreds of tests, large and small.

Although not all tests will damage the chip, but a small part of them will cause some damage to the chip.

The first batch of 12 yuan chips are not enough.

Won remembers that after he completed the nano-scale silicon-based chips, a total of 56 chips were completely damaged and 47 chips were partially damaged by various tests.

There is no rush for this step. Nano-scale chips are completely different from his previous manufacturing of magnetic core boards and millimeter-scale integrated chips.

The former are all single-layer structures, that is, on a chip base, only one layer of circuit is depicted, and where it is broken, it is easy to find out the problem.

As for the latter, just take these carbon-based chips that he just manufactured in his hand, each carbon-based chip here uses multiple superposition technology.

If you cut it open and put it under a microscope that can observe its internal structure, you will find that its cut surface is like a building assembled by building blocks.

The chips manufactured by the multiple overlay technology are like residential buildings in a community. Each building has several floors, and each floor may have different uses.

This technique has long been exploited on silicon-based chips.

Like Intel's Core series, the report shows five-nanometer process technology, but in reality it refers to the number of transistors integrated into a square millimeter of the chip has reached the five-nanometer level.

And this so-called 'one square millimeter' may be composed of two layers, or three layers, or even four or five layers of circuit structure.

Instead of a layer of single crystal material, five nanometer lithography technology is used.

Therefore, to inspect chips with this structure, the detection technology is quite critical and extremely complicated.

If there is a problem with a chip, you must not only determine where the problem is, but also determine which layer of the circuit has the problem.

With an extra layer of judgment, the difficulty can be increased by more than one layer.

With these chips, Han Yuan prepared to leave the photolithography room and went to the computer room to use the equipment inside to test them.

These chips have been preliminarily packaged, and the internal components have been protected, and they can be taken out without damaging the surface film protection layer.

Of course, before that, he replenished the lithography machine with raw materials and restarted the lithography process.

After all, judging from the previous detection of nano-scale silicon-based chips, the number of 12-element carbon-based chips is completely insufficient.

To go through all the tests, at least three-digit chips need to be prepared.

However, this is not a difficult task for South Korean Won, who is already able to mass-produce carbon-based chips, especially when there is an artificial intelligence Xiaoqi controlling it for him, it only needs to spend some time and raw materials.

In the computer room, Han Yuan took out the carbon-based chip packaged in a transparent plastic tape, and carefully put it into the testing instrument.

"There are strict requirements for chip testing, regardless of level."

After putting the pitch-black chip into the test instrument and fixing it, Han Yuan explained, and the dull voice was transmitted into the live broadcast room through the mask.

"There are three main categories of testing for an integrated circuit chip."

"Wafer test, chip test and package test respectively."

"Each step of the test has corresponding equipment to carry out. For example, the main equipment for wafer testing is the probe flat auxiliary equipment, as well as the corresponding clean room and its complete set of equipment."

"I won't say much about the wafer test, everyone should have seen it before."

After a pause, Han Yuan remembered something, and added:

"Of course, in the previous live broadcast, I not only showed and tested single crystal silicon wafers, but also graphene single crystal wafers. I also showed chip testing and packaging testing of silicon-based chips, but I didn't explain them in detail."

"Because this is the first test of a carbon-based chip, I will show its testing process in detail."

As he said that, Won also started the work of fixing the carbon-based chip and welding the reserved pins at the same time.

"Before each chip goes through the testing process, testers should fully understand the working principle of the chip."

"Not only must you be familiar with its internal circuit, but also its main parameters, the function of each lead wire and its normal voltage."

"This is the first step, and we must do it well."

"Because the chip is very sensitive, any momentary short circuit can be caught during the test, causing the chip to burn out."

"In addition, special attention should be paid when soldering the reserved pins of the carbon-based chip before testing. This is a key step for connecting an independent chip to a test instrument. short circuit between them."

[It sounds really troublesome. 】

[Digital integrated circuit analysis and design and IC analysis and design professional nightmare, this thing can make people dizzy. 】

[There is nothing simple about the chip, after all, it is something that can represent the crystallization of human's top industrial wisdom. 】

[The anchor's speech is very good, don't talk about it next time, just tell me how successful it is, how awesome it is. 】

[Pin soldering for chip testing is a nightmare. Not only must you ensure that the pins will not be burned out, but you must also ensure that there is no false soldering. If there is a false soldering, congratulations, you will get a damaged chip, and the teacher An education! 】

[Good guy, I always thought that chip design was a high-level profession, but I didn't expect to have to learn soldering. 】

[Welding offended you? 】

[Welding professional expresses dissatisfaction, not to mention chips, even rockets need to be welded to go to the sky! 】

[Welding: You are noble, you are amazing!Then you don’t live in a house, don’t use your mobile phone, don’t use your computer, or even eat. 】

【Once again, the host is not human! 】

[I really want a brain like an anchor, so that I don't have to fail the fourth grade. 】

[Stop dreaming upstairs, is that the anchor's brain?That's the quantum computing core_. 】
