The wafer looks a bit like the CD player used in a child, 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 silica that makes up quartz, grit on the beach, and even domestic glass can't be separated from silicon.

However, in order to obtain electronic-grade silicon that can be used to make chips, it must be purified by silicon elements.

The principle is simple, by heating the sand, separating the carbon monoxide and silicon, and then repeating the process until ultra-high purity electronic-grade silicon (more than 9 decimal places) is obtained.

This process of purifying silicon is called ingot in wafer processing, and after casting a high-purity silicon ingot, it is cut to a fixed specification and then further polished to obtain the wafer.

The reason why Chen Jue grabbed a cement slab was also because the cement manufacturing process was mixed with a large amount of sand, which is quartz, which is natural silica.

Originally, it was intended to extract high-purity silicon from quartz (silicon dioxide), but it was necessary to separate the carbon monoxide and silicon from it by heating and repeated purification.

However, Chen Jue has mastered the ability of [material interference] that can be called a BUG, and he can penetrate his power to the atomic level, so he does not need to adopt the traditional heating and purification method.

……

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

As Chen Jue's spiritual energy penetrated into it, the reddish substance in his palm began to have a layer of dark spots.

These spots are unwanted impurities in cement, such as calcium carbonate, silicon dioxide, 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 sculpture I saw at the market when I was a child, but it is essentially a piece of glass with high purity.

However, glass is composed of polycrystalline silicon, which is fundamentally different from monocrystalline silicon such as wafers.

"It's kind of interesting!" Chen Jue smiled, played with the transparent substance in his hand, kneaded it into various shapes as if he was playing with plasticine, and then further strengthened the plasma energy input.

With the continuous improvement of the proficiency of the [Material Interference] skill, soon the melted substance in Chen Jie's palm was further purified, and the separated carbon monoxide was ignited by the high temperature, and began to ignite a light blue flame outside Chen Jie's palm.

Liu Chengdong, who was watching this scene, was already dumbfounded!

"it!"

"Yagami An's possession?" Liu Chengdong kept complaining in his heart.

Chen Jue shook his hand, and after completely burning out those blue flames, he flattened the refined electronic-grade silicon into a thin wafer in his palm according to his own thoughts.

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

However, Chen Jue directly stepped over the step of slicing and polishing, and directly turned the refined silicon into wafers.

Just watching the wafer expand and get bigger and bigger, and finally became a boxy shape, Liu Chengdong on the side asked in surprise: "Boss, is this ...... Is this a wafer? ”

"It should be regarded as a 'wafer' of the opposite sex, and it can be called a crystal square. Wafers are processed into chips where areas of leftover material are wasted. If you make it square, you can use it 100%. Chen Jue replied calmly.

It is important to know that traditional wafer processing, according to its manufacturing process, requires high-purity silicon to be spun and grown on a daughter crystal.

However, if you do this, you will leave a lot of loss when you lith the cube-shaped chip on the wafer.

Since Chen Jue wanted to help the chip industry of the flower grower speed up, he simply improved this step of the loss process with a big brain.

"Jing Fang?"

"That's a little too big!" Liu Chengdong pursed his mouth and sighed in surprise twice.

Although he is the deputy director of the aerospace base, and his major is also biased towards the aerospace department, he is also a master's degree and has a little understanding of the chip industry.

In Liu Chengdong's impression, the current mainstream wafer processing size is about 6 inches, 8 inches, and 12 inches.

Like high-end chips below the 14nm level, most of them use 12-inch wafers. The low-end chips with a relatively large number of shipments are all 8-inch wafers.

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

However, in order to process large-sized wafers, the loss required is very large, and the processing cost is very high. At present, the highest technology mastered by human beings can only mass produce 18-inch wafers.

But what about the crystal cube in Chen Jie's palm that grew bigger and bigger?

Look at this posture, the side length of this crystal square is almost 1 meter size!

1 meter is equivalent to 39 inches, which is enough to increase the level of human wafer processing by 1 times!

What kind of processing wafer is this?

Spreading eggs is not so exaggerated!

……

After playing with the wafer he had just made, Chen Jue found that when the output plasma energy circulated in this monocrystalline silicon, a part of the extremely weak energy seemed to be connected to a charging treasure with an extremely small storage content.

"It's ...... Electronic signal transmission? Chen Jue frowned, and said secretly in his heart.

Monocrystalline silicon can be made into chips because it has good signal transmission capabilities, and the source of these signals is the movement of electrons in conductors.

However, compared with the traditional strong and weak electricity, the integrated circuit in the chip is connected to smaller microelectronics.

Since the wafer in Chen Jie's palm has just been made, the next step of lithography has not yet been carried out, and the monocrystalline silicon in it is a whole and does not form a specific circuit.

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

Seeing such results, Chen Jue knew that the next step was to etch the pre-designed integrated circuit diagram through the photolithography process, so that the chips could be extracted from them.

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

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

If you want to design a mature and effective chip, you can't avoid EDA design software.

Fortunately, the database of the base is very powerful, which includes a large number of chip design drawings at home and abroad, Chen Zhi lightly clicked the watch, and retrieved a drawing of the latest Intel 13th generation i9-13900K on the market.

It's just that when Chen Jue saw the enlarged chip design circuit diagram, his eyes widened slightly, and his mind instantly remembered the golden moire copper ban that resembled the circuit diagram in the background of the environment where the "alien" he had contacted through the five-pillar device before!

"Could it be that those lines that connect the energy of plasma are similar to this integrated circuit process?"

"Wait...... How do the wiring structures of these EDA designs look so familiar...... Combination of solder joints and lines......"

Chen Jue muttered to himself, tapped the watch in his hand, and reviewed and projected the picture of the bird and insect seal that he had seen before, which was "ordered by the sky, and lived forever", and compared it with the design drawing of the chip manufacturing process.

This time, not only Chen Jue was dumbfounded, but even Liu Chengdong on the side couldn't help but exclaim with a numb scalp at this moment: "! How can it be so similar! ”

The update is coming~ I was a little busy just becoming a dad, and I had to take care of my wife, so I really couldn't spare the time to update, so I'm sorry to everyone. I'm going to tweak it a bit and squeeze out the update time earlier.
