In order to open up the upstream and downstream industrial chains, Chen Xu was sleeping and sleeping in the laboratory, forgetting time.

The preparation process of photoresist and microspheres is quite complex, which is enough to make professional doctoral students from top universities in the world dizzy at a glance.

For example, the main components of photoresist include polymer resins, color pastes, monomers, photosensitive initiators, solvents and additives, etc.

If you want to develop it, you need to redesign and screen oligomer structures, determine and optimize the synthesis process, screening and control of active monomers, control of color paste fineness and stability... dozens of processes are needed.

There is also the high content of styrene and divinylbenzene, the raw materials of microspheres, and the iron content of stainless steel reactors used to produce microspheres exceeds the standard...

Every problem here is world-class.

Fortunately, Chen Xu's brain is quite perverted. The biological computer not only gives him super memory, but now he can also calculate in his brain like a supercomputer. Those data with large amounts of computing can only be seen to know whether the result is correct.

Then, with Xiaobai, Chen Xu's research journey was smooth.

One by one, the problems are being overcome, and while the problems are being overcome, offline factories are also being constructed simultaneously.

When Chen Xu came out of the laboratory in seclusion, the midsummer season was already in its outskirts.

The sun is scorching in the sky, and the summer cicadas are chirping~

Chen Xu was sitting on a chair under the shade of the tree and smoking, while a minor husky was rolling around on the lawn opposite.

This husky was bought and given to him by Tong Lisha. She said that his personality is getting more and more dull, and he needs a little sunshine and a little joy to adjust his life.

Although the Husky has a kingly appearance like a wolf, there is a mentally retarded child living inside, which can bring some "surprise" to his life.

It is exactly three months old today, and its talent for "destroying the house" and "save it" have not yet been displayed.

"Microsphere, come here~"

When Tong Lisha gave it to him, he was thinking about the microsphere in his mind, and then he gave it this name.

The "microsphere" rolling on the grass paused for a moment after hearing Chen Xu's voice, then suddenly got up and rushed towards him, with a mouthful of green grass leaves on his mouth.

The microball was like a young man with a slut, rushing over and jumping up and down, running happily around his legs.

Chen Xu grabbed the cigarette, then grabbed the microball, clamped its body with his legs, and removed the grass and mud on its mouth.

Microspheres are like ADHD, and their heads and bodies are constantly swaying.

Chen Xu pointed to its nose and said, "If you move again, I will suck you again."

The microsphere stopped moving, stretched out its head and licked the tip of its slightly red round nose, and its black eyes scanned around, looking pitiful.

Chen Xu cleaned the soil on his mouth before giving it loosens it, and took out a piece of biscuit from the next biscuit bag to give it.

After biting the biscuit, the microballs stopped eating them, but instead ran to the middle of the road with them in their mouths. Then they circled around the biscuits, jumping and jumping like a great god, making them feel mentally retarded.

Chen Xu laughed loudly when he saw it.

At this moment, a black mpv came in from the gate of the institute, turned around and drove towards him. In a blink of an eye, he stopped beside him with a wave of heat.

The car door opened, Lan Xi and Su Yiren walked down one after another.

Two beauties, one big and one small, Lan Xi is wearing silver-gray professional outfit + meat stockings, fluffy short hair and shiny diamond earrings, her whole body looks dignified and beautiful and generous;

Su Yiren wore white hooded short-sleeved shirts + black cropped trousers, plus white-top black sneakers, which were very refreshing and capable.

Lan Xi walked up and smiled and said, "Is it so leisurely today?"

Chen Xu laughed and said, "It's just over."

Lan Xi only knew that Chen Xu was studying things, so she didn't know what she was studying. She asked casually: "How is it? Is it going well?" She sat down next to Chen Xu.

"It's okay. Are you okay here and there any trouble?"

"It's okay! It's holiday today, so I'll ask Assistant Su to take me over to see what you're busy with."

"Well, what if I were still in the laboratory?"

"Then I'll go shopping."

"So, let's go out with you, too."

As he said that, Chen Xu pressed the smartwatch on his left wrist, leaned over and said, "Go out for a walk", and then boarded the mpv in front of him.

Lan Xi and Su Yiren also got on the car together.

While waiting for the door, two black Mercedes-Benz drove towards the road with mpvs in front and behind.

On the way, Chen Xu and Lan Xi naturally talked about the company's recent development.

"In the second quarter, Xinghai Technology's total revenue was 107.3 billion yuan and its net profit was 35.8 billion yuan... The reserves fell 11% month-on-month, with a total amount of RMB 97 billion. The main investment areas include semiconductors, biomedicine, machinery manufacturing, etc.."

After pausing, Lan Xi said, "According to your instructions, the company is studying the acquisition of two 12-inch wafer factories, which is expected to be 60 billion yuan;

If you own a sole proprietorship, it may put some pressure on the company's cash flow in the short term.

So after researching, the company decided to adopt loans or financing methods, and was planning to report to you!"

The lithography machines and some equipment of the acquired wafer factories have been eliminated, and the money is mainly spent on the factory buildings and wafers.

You should know that the construction cost of a 12-inch wafer factory alone requires more than 1 billion US dollars, including power supply equipment, ultra-clean rooms with a large area (ten thousand square meters, very high), ventilation equipment, and cooling equipment.

In addition, the factory itself is also high standard. Because wafer production is very afraid of vibration, many stabilization measures need to be taken, similar to high-rise buildings to prevent earthquakes. However, wafer factories are more difficult and costly, because the factory area covers much more than skyscrapers.

In addition, wafers, from silicon wafers to finished products, require more than 1,000 processes, which is very complicated.

There are strict standards for each of these more than 1,000 processes. With exactly the same equipment, SMIC can only build 14nm, while TSMC can build 7nm. This is the advanced process.

Hearing Lan Xi's words, Chen Xu couldn't help but shake his head.

The investment in the early stage of industrial construction is really huge. If a 12-inch wafer factory with a monthly production capacity of about 30,000 pieces will be built on its own, the investment will be as high as more than 50 billion yuan.

In addition to the country, how many private enterprises in China can afford it?

In comparison, the Internet industry is much easier. For example, Zhengfeng Games, it basically doesn’t worry much. Compared with industrial investment, it can be completely negligible.

But the money flowed in like running water.

Chen Xu thought about it and said, "Let's do this, I'll solve the money problem, and don't move the reserves again for the time being."

His overseas account has a lot of money, so it is no problem to take out some of it to buy a wafer fab.

But later equipment updates will cost a huge amount of money...

...

Chen Xu followed, Lan Xi could not really go shopping.

Finally, after asking for his own opinions, the group went to Gubei to find He Gang...
