Chapter 63 Building a Laboratory

To produce electronic-grade monocrystalline silicon, it is necessary to purify from ordinary industrial-grade monocrystalline silicon (6N) to solar-grade monocrystalline silicon (9N), and finally to electronic-grade monocrystalline silicon (11N).

Moreover, the purification of silicon becomes more and more difficult in the future, and both the technical requirements for production and the requirements for purification equipment are becoming more and more abnormal.

The most mainstream purification method in the world is the pulling method.

To put it simply, a seed crystal with a predefined orientation is used to immerse in the melt, so that the seed crystal and the melt rotate in different directions, and then slowly pull upwards. During the pulling process, the melt is in the Under the action of surface tension, the seed crystal is gradually pulled up, and cooled to crystallize into a continuous single crystal.

The single crystal silicon obtained by the pulling method is all cylindrical single crystal silicon, also known as crystal column or ingot.

Then slice the crystal column to obtain a wafer-shaped single crystal silicon wafer, which is also called a wafer.

The principle is simple to explain, but it is not easy to make the crystal column as thick as possible, and the purity of silicon must be high enough to reach the 11N level.

Currently the best in this regard is Sakura Country.

European and American countries are all behind it, let alone the current Huaguo.

If you want to use the pulling method to prepare single crystal silicon, it involves multi-disciplinary joint operations such as chemistry, physics, and mechanics. The chemical preparation is okay.

As long as there is technology, it can always be done.

But the gap in mechanical level is not so easy to erase.

For example, the production of monocrystalline silicon by the pulling method requires the use of a special electric furnace. This kind of electric furnace is not a domestic electric furnace, but the core equipment used to melt and pull single crystal silicon.

It is a pity that this equipment is also monopolized by other countries.

Therefore, Chensheng Technology wants to catch up with the level of Sakura Country in the big silicon chip, even if Lu Chen uses the technology editor to open it, it is useless.

In other words, if you have technology but no equipment, you still can't do it.

Unless Lu Chen is determined to conquer the equipment one by one, and break through the materials one by one, but in doing so, he might as well go directly to conquer the lithography machine more directly.

Besides, even if there is a technology editor open, half a year may not be enough.

Because there are not enough talents.

Some people would think that with such a large population in Huaguo, how could there be no relevant talents.

But the fact is so cruel. If an industry has no profit, it cannot support enough talents. Without talents, this industry will never catch up with others.

It's almost an endless loop.

Unless the opponent makes an extremely stupid mistake, it is too difficult to catch up with others in this field.

This can be seen from the current situation of domestic material workers.

It is very difficult for material majors to find related jobs after they complete their studies. Even if they do, the wages are much lower than those in other industries. As a result, no one is willing to enter this industry.

If you want to break this vicious circle, unless there is enough external force to intervene.

Of course, for the time being, Lu Chen definitely doesn't have this ability.

But the R-type clone he created in Kania will surely break this deadlock in the future.

For this group of people, the purpose of their studies is not simply to make money, because Lu Chen will always support them, and their only goal is to help Lu Chen or human beings develop technology.

They don't have any worries.

With this group of talented scientific researchers, coupled with Lu Chen's investment regardless of cost, it can be foreseen that it is just a humble laboratory in Kanya, and it will surely become a scientific research overlord that will shake the whole world in the future.

"This is the current status of the domestic electronic-grade large silicon wafer industry."

Hearing that Lu Chen was going to enter the large silicon wafer industry, Qin Ruolan brought a feasibility plan the next day.

This plan introduces the current situation of the large domestic silicon wafer industry, as well as several leading companies currently engaged in this industry.

According to Qin Ruolan's idea, if he wanted to achieve results within half a year, he had to use the method of investing in shares to support a large silicon chip manufacturer with the most advanced technology.

Let them catch up with their international counterparts as soon as possible.

This is not completely impossible. You must know that Huaguo's company already has the ability to produce 8-inch electronic-grade silicon wafers on a small scale.

As long as there are enough funds, it can be mass-produced completely.

8-inch electronic-grade silicon wafers have broken through, is 12-inch still far away?
Of course, even if it breaks through 12-inch silicon wafers, it is still far from the first-class level, because Shin-Etsu Daily Chemical has already been able to mass-produce 12N, 12-inch large silicon wafers.

Electronic silicon wafers of this level are the most urgently needed materials for major chip manufacturers.

Because the higher the purity of the silicon wafer, the higher the yield rate of the chip, and the easier it is to break through the existing process level.

You know, a chip the size of a fingernail means that tens of billions of transistors are laid on a silicon chip the size of a fingernail.

The so-called 3nm process refers to the interval between two transistors.

How to lay out transistors if there are impurities in the silicon wafer?
Not to mention 3nm, 12nm and even 120nm are enough, so the higher the purity of silicon wafers, the better. Chip manufacturers hope that the purity of silicon wafers can reach 100%.

Of course, there is no 100% pure substance in this world.

All substances have impurities.

The continuous advancement of the scientific level only improves the purity of single crystal silicon. For example, Shin-Etsu's laboratory has advanced the purity of single crystal silicon from 11N to 13N.

In the future, it will inevitably advance to a higher level.

"This is the information of these leading silicon wafer companies."

With that said, Qin Ruolan handed over a document.

Lu Chen took the file and flipped through it.

After a long time, he shook his head: "It's still a bit far away."

Qin Ruolan nodded, "I know, but there is nothing we can do about it. The gap between our basic materials and western developed countries is too great."

"Yes, the gap in materials is the gap in basic science. In the final analysis, our basic science is too poor."

Hearing this, Qin Ruolan pursed her lips.

We all know that the level of basic science in China is poor, but this is something that cannot be helped.

Wanting to improve the level of basic science is not as simple as improving the economy.

It takes time to settle down. To put it bluntly, this is a century-old project, and we must start with the most basic education.

Of course, if you want to improve the level of basic science, you must have sufficient economic security.

Otherwise, there will be no food to eat, and there is no talk of developing basic technology.

Lu Chen put down the information in his hands: "It's probably impossible to rely on them, because we not only need to be as simple as getting involved in the big silicon wafer industry, but also have to achieve a technological monopoly! Just like our battery management system, that's the only way, Only then can we have a certain voice in the semiconductor industry!"

Hearing this, Qin Ruolan opened his mouth: "Then what should we do?"

"First set up a laboratory to study monocrystalline silicon technology."
