Thick glasses with high myopia.

A plaid shirt with a black knit sweater on the upper body, and a scarf around his neck because of the cold.

At the bottom are jeans.

The expression is serious and does not smile.

A typical image of an engineering man.

"Dr. Pu, I'm Wei Ming, it's a pleasure to meet you."

Wei Ming walked over and stretched out his hand to him with a smile.

"You're Wei Ming?"

Pu Weicai looked at him with a surprised face, it was this young man who wanted to dig into the corner of the country and recruit him?

Shaking his head secretly.

Too young.

He understands such a young man.

It is estimated that seeing the difficult development of the chip industry in his country, and repeatedly being suppressed by foreign blockades, he was not angry, his blood was surging, and he also wanted to enter the chip-related industry, and he happened to have a little money, so he rushed in regardless of it.

He appreciates such ideas and ambitions, but does not support them.

Because it's so unbelievable!

This industry is not as easy as imagined, and it is not something that can be done with a little money.

It would take ten, twenty, thirty years, or even longer.

It takes 2 billion, 5 billion, 10 billion or more.

It requires the close cooperation of the entire industrial chain and the joint efforts of tens of thousands, hundreds of thousands of outstanding talents of all kinds.

Like this kind of young man who has a hot head, pulls up a flag, is single-handed, shouts exciting slogans, and wants to get a domestic EUV lithography machine, to be honest, he is extremely unoptimistic, and he just burns money meaninglessly.

"Dr. Pu, I have heard a lot about your deeds, high-precision duplex table, extreme ultraviolet light source technology, breaking one foreign monopoly after another, I have admired you for a long time, you are the pride of the Chinese people, and it is an example that our young people should learn......"

All kinds of compliments, no money popped out of Wei Ming's mouth.

"It's too famous, it's not that powerful."

Such commercial touting made Pu Wei a little embarrassed.

However, his mind was always very clear, and he did not listen to a few words of praise before he became drunk and lost.

After a while.

"Mr. Wei, how long has your company been established, how many technicians are there at present, and how much related equipment has been purchased? Does it have the basic conditions for R&D and production of lithography machines? Pu Weicai asked.

"Uh...... The company has just been established for more than ten days, rented a floor of office building, and a 2,000-square-meter workshop, the equipment has not been bought, and only a few cleaners have been hired to do hygiene. Wei Ming said truthfully.

Pu Weicai got up and wanted to leave, and said: "The coffee is finished, and I will have to go back to the office to work overtime, Mr. Wei, you should ask another Gao Ming, the equipment is not complete, it will take a year or two to build a shelf, I really don't have time, I waste it on things like rebuilding wheels." ”

"Wait Dr. Pu!"

Wei Ming hurriedly got up and stretched out his hand to block his way: "Don't be in a hurry, although my company has just started and has to start from scratch, it doesn't mean that my company has no strength and advantages, and it can even be said that within the whole of China, even if it starts to compete from now on, look at that Huaguo company, you can be the first to build an EUV lithography machine, I bet that it must be my black hole technology company!" ”

Hear this.

The corners of Pu Weicai's eyes twitched violently.

Looking at this young man with a confused and confident face, he didn't know what to say.

"The lens is the biggest problem in front of the domestic EUV lithography machine, I believe that you have been stuck in this problem for a long time, or it can be said that high-precision lenses are the biggest obstacle to the current domestic EUV, but ......"

Wei Ming smiled mysteriously and said, "My company can solve the problem of lenses." ”

What the?

Pu Weicai was taken aback and blurted out: "Can your company make high-precision lenses?" You have what it takes?! ”

"That's right." Wei Ming nodded.

"How do you prove it?"

"I'll show you a little thing."

Wei Ming took his backpack, opened the zipper, reached in, took out a box, and gently placed the box in front of Pu Weicai.

Pu Weicai had already sat back in his place, looking at the fist-sized square box in front of him, he was a little puzzled at first.

Until the small square box is slowly opened.

A blinding white light shot out of it, causing him to close his eyes.

When you come back to your senses.

In the small square box, there was a three-inch round glass piece lying quietly, pure transparent color.

When the outside light shines, it reflects a strong reflection and shines like a diamond.

"This is a piece of transparent glass with 100% purity, although it is not big, but its surface has been processed to a flat degree where the surface height error does not exceed 1 nanometer, if you don't believe it, you can take this piece of glass to the laboratory for verification."

Wei Ming stretched out his hand and said with a smile: "This piece of glass is a gift from me." ”

Before coming to Heshou City, Wei Ming was not unprepared.

In order to highlight his advantages and enhance his persuasiveness and attractiveness, he deliberately spent half a day using Xiao Hei to "polish" this small lens.

Although the lens is small, the surface is extremely smooth and flat, and the difference between the height of any two points does not exceed 3 atoms (i.e. 0.3 nanometers).

This level of flatness is definitely not bad compared to the Chase lenses used inside ElseMed's EUV lithography machine!

Pu Weicai was instantly attracted.

Strong reflective ability.

Unparalleled permeability.

Just by his intuition, with that luster that surpassed that of a diamond jewel, he concluded that it was a good lens!

The flatness of the surface, even if it does not reach the level of Cai Si's lenses, will surpass any domestic lens he has ever seen.

For Wei Ming's boasting, he has already believed two or three points.

Whether it's true or not, he has to go back to the lab to verify.

"Mr. Wei, I accepted this lens, I will go back to the laboratory now to see if this lens is as transparent and flat as you said, I will keep in touch with you, if your company can really solve the EUV lens problem, then we will definitely have the opportunity to cooperate!"

Pu Weicai couldn't sit still.

He couldn't wait to verify how much hope the lenses in this small square box could place on him?

"Okay, I'll wait for your news."

Wei Ming was not in a hurry, he knew that as long as the optical parameters of the small lens were measured, Pu Weicai would definitely take the initiative to contact him.

……

As expected.

Just over two hours have passed.

Around five o'clock in the afternoon.

Wei Ming received a call from Pu Weicai, and an excited and incoherent voice on the phone said: "It completely meets the requirements, the light transmittance and flatness of that lens far exceed our imagination!"

As long as the area of the lens can be enlarged to 14 inches, the thickness is about 1 inch, and the light transmittance and flatness are guaranteed to be the same as the small lens, the domestic EUV lithography machine will be able to be manufactured, we are 100% sure! ”

"No problem, standard size lithography lenses, our company can manufacture them, and mass production can be realized."

"That's great!"

Pu Weicai was even more excited: "Mr. Wei, no, Mr. Wei, please sell your company's lens products to our Institute of Optics and Mechanics, we are willing to purchase at a high price, and when the domestic EUV is successfully manufactured, you also have a share of credit, everyone will thank you for your contribution to the development of Huaguo chips!" ”

"Wait!"

Wei Ming interrupted him: "Shouldn't you and your team join my company and rebuild the EUV lithography machine, how did it become that I sold lenses to you?" ”
