Sun Jingsi first reacted and glared at Zhao Yuanjing: "Don't be arrogant and say something that is not in the sky!"

Ji Yuting seemed much gentler, but she still questioned: "Xiao Jingna, do you know what a 7-nanometer lithography machine means?"

"I know." Zhao Yuanjing nodded, "I learned a little about it yesterday."

Ji Yuting: "..."

Sun Jingsi sneered repeatedly.

A child who has a little knowledge of lithography machines is arrogant and wants to build a lithography machine himself.

Children today are really worse than those of each generation.

"If children born in the 2000s are like you, I think our country has no hope of building a 7-nanometer lithography machine within 20 years."

"I think there is still hope that it can keep up with foreign technology within ten years."

Nowadays, the latest foreign technology, lithography machines are almost reaching the level of 1 nanometer.

This technology in China is a decades away.

The research and development of any high-end technology requires the country to invest a lot of manpower and financial resources. There are too many behind in domestic research and development in this regard.

Even if I have been catching up in recent years, I can't catch up for a while.

Every Chinese feels that he is being stucked by foreigners everywhere.

As relevant practitioners, both Ji Yuting, Sun Jingsi and Su Liang deeply understand that in terms of chip research and development, there is no way to succeed without a lithography machine.

This time, when we cooperated with foreign countries, the other party broke the contract at the last moment and took away the lithography machine, which directly paralyzed the entire company.

Sun Jingsi sneered: "We are chip research and development companies, not lithography machine manufacturing companies. Even if you are a genius who has seen one hundred years, you can solve the most difficult problems. Where can I create them in a short time?"

"Xiao Sun, you are too narrow-minded." Su Liang shook his head, disagreed with his colleague's sarcasm. "If you go to a lithography machine now, of course, it will not solve our problems, but how important it will be to us in the future, don't you understand?"

Of course Sun Jingsi understood.

He was just, feeling pain and irritated by the predicament in front of him.

No one wants to watch his efforts day and night fail for more than two years.

Ji Yuting pulled Zhao Yuanjing down and asked gently: "Xiao Jing, although I don't know if you really have a way to solve several problems with 7nm lithography machines, the semiconductor knowledge you just showed far exceeded that of an ordinary junior high school student. Can you tell me where you learned it?"

"I will just read the books myself." Zhao Yuanjing opened his schoolbag and took out a few books from it.

The first thing he did after learning to buy online was to buy a bunch of books on mathematics, physics, and electronic information.

The vast and mysterious universe fascinated him.

It was a world he had never touched.

Sun Jingsi and Su Liang surrounded him and looked at his book. They found that many pages had markings and deduction formulas, all of which were shocked.

"You wrote this?" Su Liang asked.

"Yes."

"Ah, this..." Sun Jingsi murmured to herself, "The handwriting is quite good."

Ji Yuting and Su Liang stared at him together.

Although the characters are indeed good-looking, is this the focus now?

Su Liang asked Zhao Yuanjing: "You have taught you all by yourself? Or do you have a big shot in your family who guides you?"

Ji Yuting smiled.
