Then after the enchantment is completed, you need to reinforce and protect your weapon. At this time, you need to use seven deposition technologies to coat the chip with an insulating protective layer to make it more corrosion-resistant.

Finally, the silicon wafer is polished and flattened using a chemical polishing technology called CMP to make subsequent thin film deposition smoother. After repeating the steps dozens of times, the transistor and the circuit above can be engraved on the wafer, going back and forth.

It takes hundreds of times to produce 280 chips on a 6-inch wafer.

After so many steps, the wafer can be produced, but it is not yet a complete chip at this time. It still has to go through the last step, which is to check whether the chip is damaged or damaged.

After the inspection is completed, the bottom of the wafer must be polished to meet the requirements for packaging chips. However, before polishing, a layer of film must be applied to protect the circuit. After polishing is completed, it can be sent to a microtome for slicing.

Cut into wafers along the chip cutting line.

Then put the cut wafer into a lead frame coated with silver glue to bake and solidify the wafer.

We have reached the end of chip production here. After the patch is completed, wire bonding needs to be performed. A technology called thermosonic bonding needs to be used. High-frequency vibration waves are transmitted to the two surfaces that need to be welded, so that the two metal surfaces

After friction and fusion, sealing and cutting can be carried out, and the chip is basically formed.

After final testing and sorting, they can be sent to the factory for sale.

After completing these steps, two days have passed, and this is what everyone has gained through non-stop work.

"Xiao Zhong, take this chip and test it." Chen Xuezu said with dark circles under his eyes.

However, the others did not fare much better. Everyone stayed up late working with Chen Xuezu, and Zhong Feixiong put the chip on the machine for testing.

Ten minutes later...

"Teacher, there is nothing wrong with the chip." Zhong Feixiong said.

"Team Leader Wang, there is nothing wrong with the lithography machine. You can send the Frenchman back, and you can go back and do the work." Chen Xuezu said to Wang Ruian who was standing aside.

"Thank you for your hard work, Director Chen. I'll go back first." Wang Ruian nodded.

Wang Ruian finally left Changchun Optoelectronics Institute under the guidance of a staff member. He first went to the hotel to find Cai Yinlan and the Frenchman.

The hotel where the two of them stayed was not very far from the Institute of Optics and Mechanics, less than an hour's drive away. Wang Ruian made an appointment with her to meet at the hotel's coffee shop.

"There is no problem with Miss Cai's lithography machine. The money will be transferred to Tianming Company the day after tomorrow." Wang Ruian pushed the agreement and said.

"I thought it would take you a few days to solve it." Cai Yinlan said with a smile.

Because every day the Changchun Institute of Optics and Mechanics is delayed, Tuobi has to pay her one day's labor fee. For her, the longer the delay, the better.

"Director Chen and the others worked overtime for three days and nights, so they were able to confirm so quickly." Wang Ruian said with a smile.

After settling the matter with Chang Cai Yinlan, Wang Ruian rushed back to the hotel immediately. He had to catch the flight back to Shenzhen that night because Changchun was really too cold.

January 7, 2004...

Cao Mang had just arrived at the office when Zhu Youfang walked in with a pile of documents.

Zhu Youfang found a place to put down the documents and said: "Boss, the mask lithography machine has been ordered with Canon, the etching machine has been ordered with China Micro Semiconductor, the wafer cleaning machine has been ordered with Tokyo Electronics, and the ion implanter is on the way.

It is estimated that it will take another three to five days to communicate with Hans..."

Cao Mang gave the think tank a task to purchase equipment years ago.

Manufacturing chips cannot be solved with photolithography machines and packaging machines. However, the domestic technology of these two equipments is not good, and foreign countries have imposed export restrictions on domestic products. As for other equipment, there are no restrictions abroad.

There are some equipment that can be produced by domestic manufacturers. As long as the technology is not very different, Cao Mang doesn't mind purchasing from them.

This wave of purchases cost Cao Mang nearly 1.8 billion soft sister coins.

However, this amount of money is just a waste for Cao Mang. Currently, he still has more than 50 billion US dollars in his personal account. This money is his income after paying taxes, because Cao Mang previously handed it over to Luban Framework and Qinglong

Because of the chip, the superiors gave him a special tax discount of one point per ten years, and he only had to pay an individual tax of 500 million for more than 50 billion US dollars.

The leader of a certain bureau in Futian District almost fainted when he heard Cao Mang file his taxes.

If the superiors had not given Cao Mang this special tax discount, their political performance would definitely be the best in the province.

Cao Mang deposited the money in banks that would not fail in the future.

Nowadays, these banks treat Cao Mang like an uncle, and send a beautiful specialist to greet him when there is nothing wrong. These specialists are all very beautiful, and each of them can burst the buttons of his shirt.

These beautiful commissioners did not resist the leadership's arrangements but were very positive. It would be even better if the 400 billion golden bachelor could have a romantic relationship with Cao Mang and become pregnant with Cao Mang's child.

However, Cao Mang gave him a righteous warning: "If you continue to engage in these despicable tricks, I will take out all the money."

After Cao Mang's warnings, the major banks were able to calm down.

Now Xu Rang’s classmate Luo Bo... Bah... Robin is respectful to Cao Mang.

Cao Mang deposited US$5 billion in cash with Citibank, and Citibank offered him an annual interest rate of 5.5%.

"According to the report from the think tank, they found a suitable battery factory. The factory is in Pingshan New District, Shenzhen City. The name of the factory is Waterma Battery Co., Ltd."

"Why did the other party want to sell the company?" Cao Mang asked curiously.

Cao Mang, Waterma Battery, has heard that it ranks eighth in China in later generations. It ranks eighth in China's battery factory and also makes new energy buses.

It stands to reason that this company should be doing well, so why would you suddenly think of selling the company?

"Because the shareholders of their company have differences, the other two shareholders want to sell the company." Zhu Youfang replied.

Cao Mang did not expect that Waterma Battery would have such an experience. It seems that one of them should have found someone to take over these shares. This gave the company a chance to operate stably. Otherwise, the company would not have developed into the top eight.

So awesome.

"How much money do they want?" Cao Mang asked.

Cao Mang believes that acquiring Waterma at this time is a good opportunity. If he waits for another shareholder to make up his mind, it will be basically impossible to acquire Waterma again.

"The total registered capital of Waterma is 60 million. The two shareholders who want to sell their shares hold 73% of the shares. The other shareholder used a patent to invest in the shares. They want to sell 120 million in cash." Zhu Youfang
Chapter completed!
