Vol 2 Chapter 253: The magic of sand turning gold

In the huge chip manufacturing factory, engineers and scientists are busy. The entire chip manufacturing process is extremely complicated, and the requirements are very precise. Coupled with strict requirements such as dust-free, every link of the entire factory needs to be carefully, Careful design.
The technology of chip manufacturing is not a secret. Just like aero engines, everyone knows its principles, but you just can't make other advanced aero engines.
芯片 This chip has the same reason. It and the aero engine are called the jewels in the industrial crown, and they are not without reason.
The manufacture of chips begins with the conversion of quartz sand to single crystal silicon and then to silicon wafers. It has to go through extremely complicated steps such as IC design, IC manufacturing, and IC packaging and testing.
The whole process of chip manufacturing, everyone knows, there are many books on chip manufacturing on the market, and so on, and this is no secret.
But there are very few countries in the world that can turn sand into gold.
Qin Yi carefully visited the factory, watching the busy figures of the engineers, many of them have just left the campus for not long, and their faces are still immature, but everyone is very serious.
Chip manufacturing technology also has very complete technical data in the technology tower. The reason why Shen Xu can master the core technology of chip manufacturing very quickly.
On the one hand, because the chip manufacturing technology itself is bad, everyone understands that the key is to see how to do it. On the other hand, Qin Yi has taken out many key and core technical data from the technology tower.
With these core and key technologies, coupled with large sums of money, a lot of precious equipment and instruments, etc., it is reasonable to make chips.
"It is expected that our factory will be almost ready for production by the end of June."
Xu Shenxu accompanied Qin Yi as he walked.
不过 "But our factory is only doing the steps of photolithography, ion implantation, dry etching, wet etching, plasma washing, heat treatment, thermal oxidation, chemical weather deposition, physical weather deposition, etc."
"Wafer silicon, circuit design, mask manufacturing and other steps are not in this factory, but a factory cannot complete the chip equipment."
"In the future, we plan to find a place specifically to establish a chip manufacturing industry group, bringing together all the steps, factories, etc. of the entire chip manufacturing."
Qin Yi carefully watched and listened carefully. For the chip, Qin Yi really intends to hold everything in his own hands.
Unlike other industries and fields, Xinghe Technology Group only makes the most profitable cores, such as anti-gravity vehicles and anti-gravity spacecrafts. Xinghe Technology Group only makes core anti-gravity engines, control and positioning navigation systems, etc. Outsource as much as possible.
But the chip is different. Qin Yi is going to do it by himself from the beginning to the end. One is that chip manufacturing is a real high-tech field.
Even though it is the initial process of refining and refining quartz sand into wafer silicon, there are not many companies in the world that can do it, not to mention the subsequent IC design, IC manufacturing, etc. processes. There are just a few companies in the world. do.
Another aspect is still under security considerations. The core things can only be guaranteed if they have mastered all of them. It is very uncomfortable to get stuck in the neck.
"The global chip industry's annual output value exceeds 1.5 trillion US dollars. This is a very large industry. It is a good industry, but it has great promise."
Qin Yi smiled and nodded.
芯片 This chip manufacturing is also a pillar industry of Uncle Sam, such as Intel, Qualcomm, Arrow Electronics, Avnet, etc. are all well-known chip giants.
The related companies in the chip field can create an output value of more than 200 billion US dollars for Uncle Sam and contribute a profit of several ten billion US dollars each year.
More critical is that the chip is the core of modern industry. Whether it is the mobile phones, computers, etc. that everyone uses every day, or your bank cards, CNC machine tools, etc., you can't do without small chips.
If you can open the gap in this field, you can not only grab the cake of Uncle Sam, but also strengthen your own chip manufacturing technology to ensure the security of your own chip.
Time is slowly passing.
Qin Yi also attaches great importance to chips. Almost every third person will come to the chip factory for a walk.
Soon by the end of June, the chip factory can finally be put into production.
This day, Qin Yi came to the chip factory early to prepare to witness a miracle.
Originally, chip manufacturing was a big event that deserved to be celebrated and promoted. However, after thinking over and over again, Qin Yi chose to be low-key and low-key again. It was only the internal side. The company's senior management and the heads of the institutes came here Presided over the commissioning ceremony together, and did not speak up.
"Start ~"
旭 Under everyone's attention, Wang Xu gave an order gently.
Soon, the entire huge factory began to operate. Unlike ordinary factories, this chip production factory is very quiet and the sound of the machine is very low. In addition, it is a dust-free and fully automated factory. More quiet.
Qin Yi and others came to the forefront of the factory, and saw that each silicon wafer was sent into the production line and was cut into very thin pieces under the sharp blade of a high-precision automatic slicing machine.
"This is a silicon wafer. Its purity reaches 99.999999999%. When quartz sand is converted into a silicon wafer, its value has been turned over tens of thousands."
As a narrator, Xu Shenxu took everyone on a tour and explained in detail each step of chip manufacturing.
大家 "Look at this, this is the circuit diagram we designed. Have you noticed anything special?"
Soon, under the leadership of Shen Xu, everyone came to the place of IC marking.
Chip engraving is different from ordinary engraving. It uses light and shadow engraving. In simple terms, it is coated with photosensitive material on the wafer, and then the silicon wafer is irradiated with ultraviolet rays through the mask. After being washed away, the untouched areas remain as they are, so that the desired pattern can be engraved on the silicon wafer.
复杂 The complex circuits on the chip are engraved on the wafer in this way, and the key core is the circuit of the chip.
Qin Yi looked at the circuit displayed on the huge display in front of him, which was very complicated, and it seemed that he couldn't help but make it big.
However, Qin Yi soon discovered that it thought the circuit diagram he saw was different.
The circuit diagram in front of me looks a bit like an abacus. It looks like a very small abacus is mixed together in an extremely complicated way to form an extremely large and complicated circuit diagram.
它 "It looks a bit like an abacus ~"
He Linye is completely layman with no technical knowledge.
But after he took a closer look, he quickly discovered the special place.
"Haha ~ Lao Lin can see it."
"Yes, our chips are different from traditional chips. Traditionally, chips are complex circuits based on binary design. Our chips are decimal circuits based on abacus calculation rules."
Xu Shenxu explained to everyone with a smile.
In a fully automatic and intelligent factory, the machine is constantly running and requires very few workers. Of course, the workers here are not ordinary workers. They are actually engineers.
After half an hour, Qin Yi and others finally came to the end of the factory. I saw that over time, chips that have been produced have been transferred here.
Qin Yi took a chip and observed it carefully.
The chip is only the size of a fingernail, and it is very thin. The logo of Xinghe Technology Group is imprinted on it. If you take a closer look, you can see that it has extremely small and complicated patterns.
"Such a chip has a value of more than 1,000 yuan, but only when its quantity reaches a certain level, we are profitable."
"The greater the quantity produced, the lower its cost."
Xu Shenxu also held a chip and said with a smile.
"It's only 1,000 yuan, not expensive ~"
Lu Qingwei heard it, and said something unexpectedly.
"Not expensive, do you know that this thing is made of sand ~ EbookFREE.me ~ how can a little sand be worth?"
When Liu Peiqiang next to him heard it, he couldn't help but chuckle. This Lu Qingwei is getting more and more inflated now. This chip is worth thousands of Chinese yuan.
当然 "Of course I know this is made of sand. At first, I thought this chip was very expensive. I didn't expect it to be that expensive."
Lu Qingwei smiled and said.
"A single chip is already worth thousands. You need to know that the market for this chip is huge. Besides, mobile phones alone, there are billions of mobile phones in the world. You can imagine, If our virtual machines come out to replace mobile phones and computers. "
"It's a chip field alone. Even if a chip costs 1,000 Chinese yuan, you calculate how big it is."
Liu Peiqiang smiled and shook his head.
Lu Qingwei heard it, and immediately raised his finger to figure it out.
"This chip is worth 1,000 Chinese yuan. This 100 million yuan is worth hundreds of billions of yuan. If it reaches 1 billion yuan a year, it will be worth one trillion yuan."
"I'm a good girl, I don't know, I'm frightened, this market demand is too great."
After careful calculation, Lu Qingwei couldn't help but exclaim. This inconspicuous chip has too much market demand. Just count it, and its annual market value is also over one trillion yuan.
"Hehe ~ the global chip market is now over $ 1.5 trillion!"
