Chapter 347: Splendid Wafer Fab Completed!!

On the other side, the news also spread to Li Mingxuan in the imperial capital.

He knew what was going on when he knew the heads of the countries were visiting.

However, as far as the Fairview Group is concerned, there is no rush to export at all.

Anyway, iron ore is placed there, and when the time comes, the iron ore reserves of steel companies in various countries will be exhausted, and all over the world, except for the Fairview Group, they simply cannot get stable purchase channels.

That’s when Fairview Group exerts its strength.

Now you just need to dry these companies.

As for the leader of the stick country, Li Mingxuan said that Gai would not accompany him.

At this time, he was inspecting the fab on the outskirts of the imperial capital that had been completed in half a year.

The fab covers an area of 3,000 acres and has two second-hand 8-inch wafer production lines purchased at high prices from Mordor.

There are generally only two types of wafer production lines on the market now, one is 8 inches and the other is 12 inches.

Some fabs in later generations used more 12-inch wafer production lines.

The fab’s inch refers to the size of the silicon wafers of the integrated circuits it produces, the larger it produces, the more integrated circuits it produces, the lower its individual cost, and of course the more difficult it is to produce.

Because the size is doubled (diameter), the area is increased by four times.

With the same process flow and time, the output is increased fourfold.

Later generations of TSMC used basically 12-inch production lines.

In fact, the so-called fab in the semiconductor industry is called the pre-process refers to the production process of processing semiconductor devices on a single silicon wafer (each silicon chip has thousands of identical integrated circuits and other devices).

What Li Mingxuan introduced is two production lines for the production of silicon wafers.

As for the subsequent process processing of various integrated circuits on the wafer, photolithography machines and etching machines are required.

When a wafer is produced, in order to manufacture an advanced logic chip, a wafer is moved from one device to another in the fab, and the process steps can be as many as 1,000 steps.

Any defect in the equipment or process can lead to wafer defects, which in turn can affect yield.

Ni Guangnanyuan took Li Mingxuan to visit the newly built Splendid Wafer Fab while explaining the complicated procedures to him.

In fact, the current academician Ni Guangnan is not to mention how excited he is in his heart.

He never imagined that one day he would be so close to achieving his dream.

In particular, Li Mingxuan sent him nine of the world’s most advanced windmill country ASML lithography machines.

These lithography machines were all obtained by Li Mingxuan from the plaster Panasonic Wool, and they all belong to the most advanced 65nm-level lithography machine in 2005.

Although compared with the later 7 nanometers, 5 nanometer lithography machine is very different.

However, it is now the top lithography machine, which can basically meet the manufacture of all chips in the world.

The two went all the way to the dust-free workshop where the lithography machine was located.

Here some SMIC members assisted by Zhang Rujing, the godfather of semiconductors, are helping to debug the lithography machine.

It is also these people who helped build this dust-free workshop, and the 10,000-level dust-free workshop standards include the following.

Maximum allowable number of dust particles (per cubic meter); The number of particles large or equal to microns shall not exceed 350,000, and the number of particles large or equal to 5 microns shall not exceed 2,000.

Maximum allowable number of microorganisms; The number of floating bacteria should not exceed 100 per cubic meter, etc. For chip manufacturing, if there is no professional-grade dust-free workshop, it is greatly affected when processing wafers in the lithography machine.

When the two changed into dust suits and dust masks, they entered this clean and spotless dust-free workshop.

Nine of the world’s most advanced lithography machines are placed here, each as large as a bus, weighing 200 tons, and the number of parts inside the machine is said to be as high as 100,000, and the entire equipment requires two kilometers of cables.

If it were to be delivered, 40 containers would be needed, transported by three cargo planes or twenty trucks.

Fortunately, Li Mingxuan’s nanorobot worm has atomic-level resilience.

Otherwise, it is to disassemble and transport these lithography machines, which would not be possible without the professional engineers of ASM, a windmill country.

And the precision parts inside these lithography machines, once damaged, are basically impossible to repair without going to the original factory.

Whenever he saw these lithography machines, Academician Ni Guangnan, who was wearing glasses, had his eyes shining, and he couldn’t help but want to touch these machines.

You know, these machines don’t even have a state.

Because this advanced lithography machine is prohibited from exporting to countries outside the Batumi agreement, it is worth more than 100 million US dollars on the market.

And basically there is no market, you can’t buy it on the market.

And such a machine, their mysterious boss actually got nine at once.

According to the ideal state of each lithography machine, it can produce 800×600 chips a day, that is, 480,000 chips, excluding some defective products in the product, the remaining chips are about 400,000 chips a day.

Nine lithography machines can produce 3.6 million pieces a day.

Although it is far worse than the 1 billion pieces per day at the peak of TSMC in the future, it is enough for Jinxiu Microelectronics to become a super large company in chip manufacturing of flower growers.

After all, the demand for chips in 2005 was not as strong as in later generations.

“Mr. Li, I really didn’t expect the preparation to be so smooth!”

Ni Guangnan said.

“Hehe, thanks to Academician Ni, you!”

Li Mingxuan said.

“Then I have a few suggestions I don’t know if Mr. Li is willing to listen to it!”

Ni Guangnan said.

“Academician Ni, you said!”

Li Mingxuan said.

“To be honest, although I recently invited some talents in Texas Instruments to join the company, the mobile phone chip envisioned by Mr. Li is by no means something that can be completed overnight in my opinion, and the employees of the newly established company still need training for chip manufacturing, so I think if Mr. Li might as well find some chip foundries, on the one hand, he can be familiar with the operation of the fab factory 683, and on the other hand, he can train the ability of new employees!”

Ni Guangnan said.

Li Mingxuan nodded when he heard this, although chip manufacturing in 2005 was far less than that of later generations.

But the growth rate is very fast, global chip sales increased by 6.8% over last year, and total sales reached $227.5 billion.

In particular, consumer electronics such as mobile phones, digital cameras, digital TVs and MP3 players are the most important drivers of global chip sales growth.

If you can OEM part of the chip production, you can train many employees who are familiar with chip production.

This is beneficial to the future development of Fairview Microelectronics.

Of course, if he wants to make an OEM, he must not find a plaster company for the time being.

Otherwise, if these companies come to examine production capacity, there may be a risk of exposure.

Li Mingxuan felt that it was best to talk to some companies in the beautiful country.

For example, the Western Digital Company in the beautiful country to see if it can be tired of OEM flash memory chips for them.

Of course, don’t look at the opening of Jinxiu Microelectronics Company, but he has some inspirational service to the motherland and some chip design experts from Texas Instruments such as Ni Guangnan and high-paid recruitment.

Designing a process chip is still no problem.

For example, the TV set-top box chip that began to be popularized in 2005.

However, that kind of chip is actually a low-end chip, and it is a waste to use a 65-nanometer lithography machine to manufacture.
