Only science and technology can rejuvenate a country, and only science and technology can strengthen a country.

This is the consensus of all knowledgeable people.

Chu Xiangqi is no exception.

As the descendants of the Mo family's machine arts, they are naturally interested in all kinds of sophisticated equipment and have considerable talents.

Before Chu Xiangqi retired, he worked in the microelectronics laboratory in Shanghai.

This laboratory is affiliated to the Semiconductor Research Institute of the Longguo Academy of Sciences.

What he and many of his colleagues have been doing is developing and improving Longguo's cutting-edge semiconductor industry technology, trying to break the Western technological blockade and monopoly on Longguo.

Now even though he is retired, Chu Xiangqi still does some experiments from time to time when he is at home.

If the country needs it and a relevant unit re-employs him, he, like Mr. Wu, will immediately put down everything he is doing and go back to contribute his meager efforts until the end.

Lithography machine technology is stuck in the West. Where is it stuck?

As an industry insider, Mr. Chu Xiangqi knows very well.

The principle of photolithography technology is actually not complicated.

The light source passes through the lens and projects the chip design layout on the mask onto the wafer.

It's a bit like when you were in school and the teacher projected the slides onto the screen.

But if the principle is not complicated, it is useless. Whether it can be made concretely is the key.

This is just like nuclear weapons. Which country's scientists don't understand the principles of making nuclear weapons?

But how many countries in the world are capable of possessing nuclear weapons?

Mr. Chu Xiangqi has been immersed in the semiconductor industry his entire life. He clearly knows how difficult it is for photolithography technology to break through the blockade.

The high precision and high speed of photolithography are the two most difficult points to break through in advanced photolithography machine technology.

They have been studying in the Magic City Microelectronics Laboratory for decades, but they still have not been able to completely break through the technical barriers.

But at this time, Teacher Xu actually told him on the phone that his friend had obtained a 3-nanometer photolithography machine abroad?

And he is very patriotic and wants to hand it over to the country?

Even though Mr. Chu Xiangqi had experienced great storms in his life, he was completely confused at this time.

Even if his cell phone fell to the ground, he didn't notice it.

His impression of Teacher Xu is very good.

In just one parent-teacher meeting during the mid-term exam last semester, the old man saw that Teacher Xu is a teacher and always considers his students.

In subsequent daily exchanges, the old man was even more impressed with Teacher Xu.

In his impression, Teacher Xu is not a braggart or a big talker.

But 3nm lithography machine?

This is a big deal.

The old man could not believe that all this was true.

After the shock, Mr. Chu Xiangqi picked up his cell phone, his thoughts changing rapidly.

"Teacher Xu, this kind of thing is not a joke."

“It’s not like we don’t have photolithography machines in our country.”

"For conventional chip manufacturing, such as TV, computer chips, etc., we have already been able to achieve independent research and development and manufacturing."

"What we lack is a breakthrough in precision in the field of the most advanced photolithography technology."

"In 2018, a domestic company spent more than 100 million US dollars to order a photolithography machine from abroad."

"But due to the obstruction of the beautiful country, the transaction was eventually terminated."

"Quite literally."

"Every 3-nanometer lithography machine in the world has attracted the attention and attention of countless people since it was manufactured."

"There have been many patriotic entrepreneurs and patriotic overseas Chinese who have tried to use some unconventional methods to make some contributions to our country's lithography technology."

"But they all ended in failure."

"So, I need to confirm with you now."

"Are all these things you said true?"

Xu Jie understands the old man's caution very well.

He is just a high school teacher.

Is there a friend who was able to get a 3-nanometer photolithography machine from abroad?

What kind of international joke are you kidding?

But Xu Jie knew that with a system, how could he use common sense to judge it?

Not only can he get photolithography machines, he also has a military base overseas!

Who can believe this?

"Old man, I assure you that everything I said is true."

At the base, Xu Jie smiled and replied:

"This photolithography machine has been secretly shipped back to China by my friend."

"I just need the old man's help to find someone to verify the authenticity. Isn't everything clear?"

Xu Jie has a network connection card, and he can actually contact people in relevant departments.

But since he knew that the old man was engaged in this industry, why bother to make any detours?

Besides, contacting the boss through the old man will bring benefits to the old man, Chu Mo and the entire Chu family!

Xu Jie plans to use this photolithography machine handover to help his student Chu Mo plan a broader future!

"Okay, Teacher Xu, I believe you."

"I'll contact the superior department right away."

Mr. Chu Xiangqi pondered for a moment and decided to report it to the superior.

Although he doesn't have much contact with Teacher Xu, he has great optimism and trust in Teacher Xu.

A good teacher who can wholeheartedly consider his students and teach them with all his heart will not make fun of something as involved as a photolithography machine.

Just do it.

After hanging up the phone, the old man dialed a number he had not contacted for a long time.

Beep...beep...beep...

After waiting for more than ten seconds, the call was connected.

"Huh? Lao Chu? Why, what tricks did you come up with at home?"

A loud voice came from the other end of the phone.

The voice was full of joking.

"Lao Li, please stop teasing me."

Mr. Chu Xiangqi smiled and said:

"Has there been any progress in the institute's research recently?"

Old Li, whose name is Li Ru, is the current leader of the Magic City Microelectronics Laboratory.

"There's not much progress on our side."

Li Ru sighed helplessly, "We old guys are useless!"

"On the other hand, Yunhai and the others seem to have made a breakthrough."

"Didn't they tell you?"

Chu Xiangqi was stunned.

"Is there any progress on Yunhai's side?"

"Is the breakthrough big?"

Li Ru laughed.

"I just heard about it."

"Yunhai is your precious son, a talent trained by your old Chu."

"Since you don't even know about it, I guess the breakthrough should be quite big."

"By the way, what do you want from me?"

"If you want to come back and continue your research, then I can't make the decision. I can only help you report to your superiors."

Mr. Chu Xiangqi smiled and shook his head.

"It's not my own business."

"There are overseas patriots who got a 3-nanometer photolithography machine from some source and want to hand it over to the country."

Bada.

A voice came from the other end of the phone.
