In order to open up the upstream and downstream industrial chains, Chen Xu soaked in the laboratory without sleep and food, forgetting the time.

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

For example, the main components of photoresist are polymer resin, color paste, monomer, photoinitiator, solvent and additives.

If you want to develop it, you need to redesign and screen the oligomer structure, determine and optimize the synthesis process, screen and control the active monomer, control the fineness of the color paste, and stabilize it... Dozens of processes.

There are also high impurities in styrene and divinylbenzene, the raw materials of the microspheres, and the iron content of the stainless steel reactor used to produce the microspheres exceeds the standard......

Every puzzle here is world-class.

Fortunately, Chen Xu's brain is more perverted, and the biological computer not only gives him super memory, but now it can also allow him to perform calculations in the brain like a supercomputer.

Then coupled with Xiaobai, Chen Xu's research path was finally smooth sailing.

One problem after another has been overcome, and at the same time as the problem is overcome, the offline factory is also under construction.

When Chen Xu came out of the "retreat" in the laboratory, it was already in the middle of summer.

When the sun is in the sky, the summer cicadas are chirping~

Chen Xu sat on a chair in the shade of a tree and smoked, while an underage husky was rolling on the lawn opposite.

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

Although the husky has the appearance of a wolf-like king, there is a mentally handicapped child living inside, which can bring some "surprises" to his life.

As of today, it is exactly three months old, and its talent of "demolition" and "abandonment" has not yet had a chance to show.

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

Like a young man, Microsphere rushed over and jumped up and down, running happily around his legs.

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

Microspheres are like ADHD, the head and body are constantly shaking.

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

The microsphere stopped moving all of a sudden, stretching out its head and licking the tip of its reddish round nose, and its dark eyes scanned around, looking pitiful.

Chen Xu cleaned the dirt from his mouth before loosening it for it, and took out a biscuit from the biscuit bag next to it and gave it to it.

After biting the biscuit, the microsphere did not eat it, but ran to the middle of the road to put it down, and then circled around the biscuit, jumping and jumping like worshipping a great god, and escaped a mentally retarded person.

Chen Xu laughed when he saw it.

At this moment, a black MPV came in from the direction of the entrance of the research institute, turned the corner and drove towards him, and in the blink of an eye, it stopped next to him with a wave of shocking heat.

The car door opened, and Lan Xi and the Sui walked down one after another.

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

The Sui people are wearing white hooded short sleeves + black cropped pants, plus white gangs and black sneakers, which are very refreshing and capable.

Lan Xi walked up and said with a smile: "So leisurely today?"

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

Lan Xi only knew that Chen Xu was studying things, and it was not clear what he was studying, so he asked casually, "How is it, is it smooth?" and sat down next to Chen Xu as he spoke.

"It's okay. Is there anything wrong with you guys coming here?"

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

"yes, what if I'm still in the lab?"

"Then I'll go shopping. ”

"Well, let's go, I'll go out with you too. ”

As he spoke, Chen Xu pressed the smart watch on his left wrist, brought it to his lips and said, "Go out for a walk", and then boarded the MPV in front of him.

Lan Xi and the Sui also got into the car together.

When they waited for the door, two black Mercedes vehicles drove towards the road with MPVs in front of them and one behind them.

On the way, Chen Xu and Lanxi naturally chatted 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... Reserves fell 11% from the previous quarter to a total of RMB97 billion, with major investments in semiconductors, biomedicine, machinery manufacturing, etc. ”

After a pause, Lan Xi said: "According to your instructions, the company is studying the acquisition of 2 12-inch wafer fabs, and the estimated amount required is 60 billion;

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

Therefore, after research, the company decided that it is ready to take the form of loan or financing, and is planning to report to you!"

The lithography machines and some equipment of the acquired fabs have been phased out, and the money is mainly spent on the fab and wafers.

You must know that a 12-inch wafer factory needs more than 1 billion US dollars to build a factory alone, including power supply equipment, a large ultra-clean room (tens of thousands of square meters, which is still very high), ventilation equipment, and cooling equipment.

In addition, the factory itself is also of high standard, because wafer production is very afraid of vibration, so a lot of stabilization measures have to be taken, similar to high-rise buildings to prevent earthquakes, but the fab is more difficult and costly, because the plant covers much more than skyscrapers.

In addition, the wafer, from the silicon wafer to the finished product, needs to go through more than 1,000 processes, which is very complex.

These more than 1,000 processes, each of which has strict standards, exactly the same equipment, SMIC can only make 14nm, while TSMC can make 7nm, which is the advanced process.

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

The investment in the early stage of industrial construction is too huge, and a 12-inch wafer factory with a monthly production capacity of about 30,000 pieces will invest more than 50 billion yuan if it is built by itself.

In addition to the state, how many private enterprises in China can afford to play?

In comparison, the Internet industry is much easier, like the battle game, he basically didn't worry much, and the upfront investment is completely negligible compared with industrial investment.

But the money flowed in like flowing water.

Chen Xu thought about it for a while and said: "In this way, I will solve the matter of money, and the reserve fund will not be moved for the time being." ”

His overseas account is very well funded, and there is no problem in using part of it to buy fabs.

It's just that it costs a lot of money to update the equipment later......

……

Chen Xu followed, and it was impossible for Lan Xi to really go shopping.

Finally, after consulting his own opinion, the group went to Gubei to find He Gang......
