I’ll add some practice in the real world

The wafer looks a bit like the discs used in CD players that were common in childhood, but its actual purpose is to make semiconductor circuits.

As for the material that makes up the wafer, it is silicon which is very common in nature.

Silica is the component of quartz, gravel on the beach, and even household glass.

However, in order to obtain electronic-grade silicon that can be used to make chips, the silicon element must be purified.

The principle is very simple. It is to heat the sand to separate the carbon monoxide and silicon in it, and then repeat this process until ultra-high purity electronic grade silicon is obtained (more than 9 decimal places).

This process of purifying silicon is called ingot casting in wafer processing. After casting a high-purity silicon ingot, it is cut according to fixed specifications, and then further polished to finally obtain a wafer.

The reason why Chen Jue picked up a cement board was because a large amount of sand was mixed in the cement manufacturing process. The sand is quartz, which is natural silica.

Originally, we wanted to extract high-purity silicon from quartz (silica), which required heating and repeated purification to separate the carbon monoxide and silicon.

However, Chen Jue has already mastered the [matter interference] ability that can be called a BUG. He can penetrate his power to the atomic level, so there is no need to use traditional heating and purification methods.

…

A golden energy spread out from Chen Jue's five fingers, and the cement block in his palm began to melt under the stimulation of plasma energy, turning into a large lump of magma-like material.

As Chen Jue's spiritual energy penetrated, the red material in his palm began to have a layer of dark spots.

These spots are excess impurities in the cement, such as calcium carbonate, silica, etc.

After these unused impurities are removed, the remaining material is melted and cast into a red and translucent substance under the stimulation of high temperature. It looks a bit like the sugar sculptures I saw at the market when I was a kid, but it is essentially a piece of extremely pure glass.

However, glass is composed of polycrystalline silicon, which is essentially different from single crystal silicon such as wafers.

It's quite interesting! Chen Jue smiled and played with the transparent substance in his hand, kneading it into various shapes like playing with plasticine, and then further enhanced the plasma energy input.

As the [Substance Interference] skill continued to improve, the melted substance in Chen Jue's palm soon became further purified. The separated carbon monoxide was ignited by the high temperature and began to ignite a light blue light outside Chen Jue's palm. of flame.

Liu Chengdong who was watching this scene was already stunned!

Fuck!

Is Yashenan possessed? Liu Chengdong kept complaining in his mind.

Chen Jue waved his hand, and after completely burning out the blue flames, he flattened the extracted electronic-grade silicon into a thin wafer on his palm according to his own will.

According to the wafer processing process, the originally extracted electronic-grade silicon needs to be cast into silicon ingots and then cut into slices.

But Chen Jue directly skipped the slicing and polishing step and directly transformed the extracted silicon into wafers.

Just watching the wafer expand and grow, and finally turned into a boxy shape, Liu Chengdong on the side asked in surprise: Boss, this...is this a wafer?

It should be regarded as a 'wafer' of the opposite sex. You can call it a wafer. When the wafer is processed into a chip, there will be leftover areas that are wasted. If it is made into a square shape, it can be 100% utilized. Chen Jue He replied calmly.

You must know that traditional wafer processing requires high-purity silicon to be grown on a daughter crystal by rotating it.

However, this will leave a lot of loss when photoetching square chips on the wafer.

Since Chen Jue wanted to speed up the flower grower's chip industry, he simply used his imagination to improve this loss process.

Jingfang?

Then this size is a bit too big! Liu Chengdong pursed his lips and sighed in surprise.

Although he is the deputy director of the aerospace base and his major is in the aerospace department, he still has a master's degree and has some understanding of the chip industry.

In Liu Chengdong's impression, the current mainstream wafer processing sizes are roughly maintained at three specifications: 6 inches, 8 inches, and 12 inches.

High-end chips below the 14-nanometer level mostly use 12-inch wafers. Mid-range and low-end chips with relatively large shipments all use 8-inch wafers.

In short, the larger the wafer size, the better, because the larger the size, the more chips can be cut from it.

However, if you want to process large-size wafers, the losses generated will be very large and the processing cost will be high. The highest technology currently available to humans can only mass-produce 18-inch wafers.

But what about the growing crystal cube in Chen Jue's palm?

Looking at this posture, the side length of this crystal cube is almost 1 meter!

1 meter is equivalent to 39 inches, which has doubled the level of human wafer processing!

Where is this processing wafer?

Spreading eggs is not that exaggerated!

…

After playing with the wafer he had just made, Chen Jue found that when his output plasma energy circulated in this single crystal silicon, some of the extremely weak energy seemed to be connected to a power bank with extremely small storage content. Same.

Is this... electronic signal transmission? Chen Jue frowned and thought to himself.

The reason why single crystal silicon can be made into chips is because it has good signal transmission capabilities. The source of these signals comes from the movement of electrons within the conductor.

However, compared to traditional strong and weak currents, the integrated circuits in the chip communicate with smaller microelectronics.

The wafer in Chen Jue's palm has just been made and has not yet undergone the next step of photolithography. The single crystal silicon inside is a whole and does not form a specific circuit.

Therefore, that part of the electronic signal is transmitted in an orderly manner like a headless fly.

Seeing such a result, Chen Jue knew that the next step was to use the photolithography process to etch the integrated circuit pattern designed in advance, so that pieces of chips could be extracted from it.

It's just that chip design, like chip processing, is a relatively stuck technology in China. This involves a design tool called EDA.

EDA is known as the mother of chips, and translated into Chinese it means electronic design automation.

If you want to design a mature and effective chip, you cannot avoid design software such as EDA.

Fortunately, the base's database is very powerful, including a large number of domestic and foreign chip design drawings. Chen Jue tapped his watch and retrieved a drawing of the latest Intel 13th generation i9-13900K on the market. come out.

But when Chen Jue saw the enlarged chip design circuit diagram, his eyes widened slightly, and his mind instantly recalled the environment and background of the alien that he had contacted through the five-pillar device. The golden moiré copper ban is the same as the circuit diagram!

Could it be that those lines connecting plasma energy are similar to this integrated circuit manufacturing process?

Wait... why do the wiring structures of these EDA design drawings look so familiar... the combination of solder joints and lines...

Chen Jue muttered to himself, tapped his watch on his hand, and projected the picture of the bird and insect seal that he had seen before, Ordered by Heaven, Live Long and Prosperous, together with the design drawing of the chip manufacturing process. Side by side comparison.

At this time, not only Chen Jue was dumbfounded, but also Liu Chengdong on the side couldn't help but screamed with numbness: Fuck! How can it be so similar!

The update is here~ I'm a little busy as a new dad, and I have to take care of my wife. I really can't spare the time to write an update. I want to say sorry to everyone. I will make some adjustments next and squeeze out the update time as soon as possible.
