Leveling Up My Cultivation in the Real World - Chapter 362: Coincidence of Integrated Circuit!

Chapter 362: Coincidence of Integrated Circuit!

The wafer looks a bit like the CD used in CD players when we were young, but its actual use is to make semiconductor circuits.

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

Silicon is found in silica, the material that makes up quartz, in the sand on the beach, and even in the glass we use at home.

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

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

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 ground and polished to finally obtain a wafer.

The reason why Chen Jue grabbed a piece of cement board was because a large amount of sand was mixed in the manufacturing process of cement. Sand is quartz, which is natural silicon dioxide.

Originally, if you wanted to extract high-purity silicon from quartz (silicon dioxide), you would need to heat and repeatedly purify it to separate the carbon monoxide and silicon.

However, Chen Jue has already mastered the [Matter Interference] ability which is like a BUG,

and can penetrate his power to the atomic level, so there is no need to adopt the traditional heating and purification method.

…

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 mass of magma-like substance.

As Chen Jue’s spiritual energy penetrated into the palm, the red substance in his palm began to show a layer of dark spots.

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

After removing these useless impurities, the remaining materials are melted 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 child, but it is essentially a piece of extremely pure glass.

However, glass is made of polycrystalline silicon, which is fundamentally 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 plasticine, and then further strengthened the plasma energy input.

With the continuous improvement of his proficiency in the [Matter Interference] skill, the molten substance in Chen Jue’s palm was soon further purified. The separated carbon monoxide was ignited by the high temperature and began to burn a light blue flame outside Chen Jue’s palm.

Seeing this scene, Liu Chengdong who was standing aside was already stunned!

“Fuck!”

“Is Iori Yagami possessed?” Liu Chengdong kept complaining in his heart.

Chen Jue shook his hands, and after the blue flames were completely burned out, he spread the refined electronic-grade silicon on his palm into a thin wafer according to his own will.

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

However, Chen Jue skipped the slicing and polishing steps and directly turned the refined silicon into wafers.

Just as the wafer expanded and grew larger, and finally became a square shape, Liu Chengdong, who was standing by, widened his eyes and asked in surprise: “Boss, this… is this a wafer?”

“It should be considered a ‘wafer’ of the opposite sex. You can call it a crystal cube. When the wafer is processed into a chip, there will be a wasted area of

scraps. If it is made into a square, it can be fully utilized.” Chen Jue replied calmly.

You should know that traditional wafer processing, according to its manufacturing process, requires high-purity silicon to be grown by rotation on a sub-crystal.

However, doing so will cause considerable losses when photolithography of the square-shaped chips on the wafer.

Since Chen Jue wanted to help speed up the chip industry of the Flower Planting Family, he simply came up with an idea and improved this step of the loss process.

“Jingfang?”

“Then the size is a bit too big!” Liu Chengdong pursed his lips and clicked his tongue in surprise.

Although he is the deputy director of the aerospace base and his major is in aerospace, he is a master’s degree holder after all and has some understanding of the chip industry.

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

Most high-end chips below 14 nanometers use 12-inch wafers, while mid- and low-end chips with large shipments 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-sized wafers, the loss is very large and the processing cost is very high. The current technology that humans have mastered can only mass-produce 18-inch wafers at best.

But what about the crystal cube in Chen Jue’s palm that is getting bigger and bigger?

Judging from the situation, the side length of this crystal cube is almost 1 meter!

1 meter is equivalent to 39 inches, which doubles the human wafer processing level!

How can this be called wafer processing?

Even scrambled eggs are not this exaggerated!

…

The latest novel is published first on Liu9shuba!

After playing with the wafer he had just made, Chen Jue discovered that when the plasma energy he outputted was flowing through this single crystal silicon, a part of the extremely weak energy was like being connected to a power bank with extremely small storage capacity.

“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 with traditional high and low voltage, the integrated circuits in the chip use much smaller microelectronics.

The wafer in Chen Jue’s hand had just been made and had not yet undergone the next step of photolithography. The single crystal silicon inside was a whole and had not formed a specific circuit.

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

Seeing this result, Chen Jue knew that the next step was to use the photolithography process to etch the pre-designed integrated circuit pattern so that the chips could be extracted from it.

Chip design, like chip processing, is a technology that is currently facing a bottleneck in China, and it involves a design tool called EDA.

EDA is known as the mother of chips, and translated into Chinese 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, which includes a large number of domestic and foreign chip design drawings. Chen Jue lightly tapped his watch and retrieved a drawing of the latest Intel 13th generation i9-13900K on the market.

However, when Chen Jue saw the magnified chip design circuit diagram, his eyes widened slightly, and his mind instantly remembered the golden cloud-patterned copper bans that looked like circuit diagrams in the environment background of the “alien” he had contacted through the five-pillar device before!

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

“Wait… why do the wiring structures in these EDA design drawings look so familiar… the combination of solder joints and wires…”

Chen Jue muttered to himself and tapped his watch lightly. He projected the image of the bird-and-insect script “Received the Mandate from Heaven, May You Live Long and Prosper” that he had seen before, and compared it side by side with the design drawing of the chip process.

This time, not only Chen Jue was dumbfounded, but even Liu Chengdong beside him couldn’t help but screamed with a tingling scalp: “Fuck! How can they be so similar!”

Update is coming~ I’m a little busy as a new dad, and I have to take care of my wife, so I really can’t spare the time to write and update. I apologize to everyone. Next, I will make some adjustments and squeeze out the update time as soon as possible.
