The equipment of Qilin Laboratory has also been put in place. It took a total of four months and cost Cao Mang a total of 320 million soft sister coins, which was 20 million more than originally expected.

Ke Zhen's parents introduced another group of chemical engineering doctors, and Cao Mang gave them a formula for polycarbonate derivative molecules.

"Mr. Cao, what is this?" Kong Ling'er asked in confusion.

"This is the photoresist formula I bought from a laboratory abroad, the molecular formula of polycarbonate derivatives. I hope you can reproduce it," Cao Mang replied.

Polycarbonate derivatives: also known as chain-breaking photoresist.

The main chain of this photoresist contains easily dissociable carbonate groups. Under EUV irradiation, the polymer decomposes into CO2 and many low molecular weight fragments. These fragments can increase the solubility in the developer and are removed during development.

This type of photoresist has high resolution and low line edge roughness.

"Don't all current photoresists use poly(para-hydroxystyrene) resin?" Kong Ling'er asked with a frown.

"That's the photoresist for deep ultraviolet lithography machines. What you are developing this time is extreme ultraviolet lithography machines. Foreign countries have already begun to study extreme ultraviolet lithography machines. It is no longer meaningful for us to study deep ultraviolet lithography machines."

." Cao Mang replied.

"We will reproduce it as soon as possible." Kong Ling'er nodded.

The manufacturing technology and patents of deep ultraviolet photoresist are now in the hands of Europe and the United States. To produce deep ultraviolet photoresist, you must bypass their patents. If you want to bypass their patents, you have to pay a huge price. No one is afraid of 2 to 3 billion.

It cannot be researched.

Extreme ultraviolet photoresist is still blank at present. How can we go back and study deep ultraviolet photoresist?

Of course, there is not only one kind of deep ultraviolet photoresist, but other formulas of photoresist are not good enough, and the patents for other formulas are also in Cao Mang's hands.

In the future, it will be basically impossible for Europe and the United States to break through Cao Mang’s patent barriers in extreme ultraviolet photoresist.

Cao Mang thought very clearly.

You won’t sell photolithography machines to us?

Then we won’t sell photoresist to you.

Without photoresist, your photolithography machine is useless.

Unless Ou ignores patent issues and manufactures photoresist, to put it bluntly, patents are the protective umbrella of capitalists. They are the ones who least want to see this umbrella broken, so this kind of thing is basically impossible to happen, no matter it is

No country dares to break this rule.

...

The time came to April 19, 2003.

Luo Guijuan made an appointment with her boyfriend to play games at an Internet cafe.

"Ah~~~" Luo Guijuan just entered the Internet cafe and saw the roll-up in front of the cashier. She took her boyfriend's finger and pointed at the roll-up, jumping up and down and screaming.

"What kind of seal do you give, what is your name?" Luo Guijuan's boyfriend Zhuang Hao covered his ears and said after Luo Guijuan finished calling.

"Chou has released a new album." Luo Guijuan narrowed her eyes and smiled happily. She is a loyal fan of Jay Chou and the vice president of the Shenzhen Jay Chou Fan Club.

"It's out as soon as it's out. If there's anything to shout about, you don't mind being embarrassed." Zhuang Hao rolled his eyes and said.

There are photos of people walking around and sitting on chairs printed on the roll-up banners. There are several big characters on the roll-up banners saying Jay Chou's latest album "Yip Huimei", and the checkout counter is full of albums of "Yip Huimei".

This album was originally planned to be released in July, but after Jay Chou was packaged and sold to Kirin Media, the album was released ahead of schedule.

"Waiter, do you also sell Jay Chou's albums here? Are they genuine? How much does one cost?" Luo Guijuan asked.

"It's genuine. Jay Chou is now an artist of our Kirin Media. If you want to buy Jay Chou's album, you can place an order on Kirin Music." the cashier clerk replied.

"Ah? Do you still want to place an order? Can't you just buy it offline?" Luo Guijuan asked.

"Sorry, miss, we only support online purchases now. If you want to buy, you can recharge here." The waiter replied.

"Oh. How much does Jay Chou's album cost?" Luo Guijuan asked again.

"25 yuan a piece." the waiter replied.

"Oh, then you can recharge 25 yuan for me." Luo Guijuan said.

"I'm sorry, miss, but Qilin Music only has 15, 30, 50, and 100 sizes. You can recharge 30 yuan, which can be used in the future," the waiter said.

"Okay, let me top up the money with 30 yuan," Luo Guijuan said speechlessly.

It only costs 25 yuan to buy an album, and you have to recharge 30 yuan, which is very frustrating no matter who you are.

However, they do not know that this recharge specification is intentional. It is set purely to increase customer stickiness. The money reserved by customers in Kirin Music can also lay a certain foundation for future sales and also cultivate customer consumption.

Habit.

If a single is released in the future and sells for 3-5 yuan, customers will like to see that there is still 5 yuan lying in their account. I believe most people will choose to buy the single.

In addition to ground promotion in Internet cafes, large advertisements on Kirin Music and Facebook, as well as a large number of trolls for promotion, attracted the attention of countless netizens.

...

Yu Zhongwen is also a fan of Jay Chou. When he opened Qilin Music, he saw Ye Huimei's promotional advertisement, but when he clicked in, he started listening to the song.

However, each song only played for one minute and then ended. At this time, Qilin Music reminded him that the audition was over. If he wanted to listen to the full version, he had to buy a genuine CD to listen to the complete song on Qilin Music. As a prostitute Yu Zhongwen,

He decided to check out the pirated websites.

The pirated website did not disappoint him. Songs from Jay Chou's new album did appear. However, after Yu Zhongwen clicked to play, the pirated website could still only play for one minute, so he had no choice but to go to an Internet cafe and buy a genuine CD.

There are many people like Yu Zhongwen. It's not that pirated websites can't pirate, but that as soon as they put pirated songs on the shelves, the server was hacked and the complete MP3 file was replaced with a 1-minute trial version.

The servers are all using windows

server system, windows

Don't have too many loopholes on the server, as it won't be able to withstand Cao Mang's invasion.

On the day the album was released, Cao Mang hired several technicians. Their job was to invade pirate websites and modify pirated MP3 files.

...

The administrator of the pirated website was confused when he logged into the server the next day. The desktop background had been modified without anyone knowing when.

Leave a line on the desktop background image saying that you are not allowed to pirate the albums sold by Qilin Music, otherwise your server will be formatted next time.

As the administrator of a pirated website, Long Dingkun decided to remove all of Jay Chou's albums when he saw the desktop background picture. Since the other party can invade his system, they must be able to format his server. Obviously such a big deal

He can't afford to offend him.
