Chapter 0229: We Want to Build a Lithography Machine!!

“Wei Dong, isn’t this idea of yours a little too complicated.”

After Lin Weidong said all his thoughts, Professor Li said with some hesitation.

Of course, this is not that he does not agree with Lin Weidong’s design.

If he could, he certainly wanted to execute according to Lin Weidong’s design.

But as I said before, the meal should be eaten bite by bite, and the road should be taken step by step.

If you want to eat into a big fat person in one go, it is easy to choke yourself to death.

But in response to Professor Li’s questions, Lin Weidong insisted on his own ideas.

“Li Lao, the strength of the army is the withdrawal of a country’s strength.”

“And the army is divided into army, navy and air force.”

“But compared to those powerful countries, the only thing we can do is the army.”

“And it does not rely on how advanced weapons and equipment, but on the spirit of the fighters who are not afraid of death and dare to fight.”

Hearing Lin Weidong’s words, everyone present fell silent.

Because they knew that Lin Weidong was telling the truth.

Lin Weidong continued: “Our strength in the air force and navy is still too weak. ”

“Trying to catch up with the strength of the Western powers is not something that can be done in a short time.”

“Especially on battleships, the gap on aircraft carriers is very large.”

“If we want not to be bullied, we can only further strengthen the strength of the road army.”

“Once we are equipped with sufficiently powerful tanks, no one will dare to underestimate us.”

Hearing Lin Weidong’s words, everyone showed a longing look.

But then Professor Li looked embarrassed.

“Wei Dong, you have drawn this pie very well, but the techniques you mentioned, I’m afraid it will be difficult for us to complete.”

“Especially the technology on some program systems, it is too difficult to manufacture.”

“And even if it is really researched, I am afraid I don’t know how long it will take.”

“In this way, it has dragged down the strength of the army.”

Hearing Professor Li’s words, Lin Weidong’s face suddenly turned dark, what did he call this big pie very good.

“Professor Li, I don’t know if you know the lithography machine.”

Lin Weidong suddenly asked.

“Lithography machine, of course I know.”

Professor Li nodded: “Last year, a certain Western country developed an instrument called a lithography machine. ”

“The feeling is similar to the optical plotter, which is also related to the circuit, but more precise.”

“That’s right!”

Lin Weidong nodded.

“The lithography machine is an instrument specially used to make chips.”

“And the chip is actually a general term, to be precise, it is an integrated circuit, which is equivalent to integrating a lot of electronic components into a small silicon chip.”

“In this way, it can do a lot of circuit functions on a single silicon chip.”

“With the help of a lithography machine, the time it takes us to develop a tank system will be greatly reduced.”

Hearing Lin Weidong’s words, everyone else was overjoyed.

But Professor Li and Professor Liu did not show joy.

Because they all know that it is impossible for a certain Western country to sell them a lithography machine.

Seeing their expressions, Lin Weidong naturally knew what they thought.

So he said with a smile: “Lithography machine, they will definitely not sell it to us, and they will block us technically.” ”

“But they don’t give it, we can make it ourselves.”

“If only we could make it…”

Professor Li said subconsciously, but reacted halfway through.

What Lin Weidong meant when he said this was…

“That’s right, I also have a hundred million points of research on the technology of lithography machines.”

“In other words, since I first designed the photoplotter, I have been studying the technology of the lithography machine.”

When everyone heard this, they immediately gasped.

At this time, they finally felt the gap between themselves and Lin Weidong, even Professor Li and Professor Liu.

“Wei Dong, you can really make a lithography machine.”

Professor Li still asked in disbelief.

“No jokes.”

Lin Weidong nodded seriously.

“The working principle of the lithography machine is to use the light emitted by the lithography machine to expose the thin sheet coated with photoresist through a mask with a pattern.”

“The properties of the photoresist change after seeing light, so that the pattern on the mask is copied to the sheet, so that the sheet has the function of an electronic circuit diagram.”

“Similar to a camera photograph, but the camera takes a picture printed on a negative, and the lithography is not a photograph, but a circuit diagram and other electronic components.”

“To put it simply, the lithography machine is an enlarged SLR, and the lithography machine is to print the designed integrated circuit pattern on the mask to the photosensitive material through the exposure of light to form a pattern.”

“The lens is the most core part of the lithography machine, the light source is also one of the core of the lithography machine, followed by resolution, over-engraving accuracy…”

With Lin Weidong’s explanation, they found that it seemed that it was really possible to come up with a lithography machine.

“Wei Dong, if we cooperate fully, how long will it take you to manufacture a lithography machine.”

Professor Li asked.

Whether it is for the current tank research and development work, or for the various high-tech products lithography machine in the future, they must come out.

“Three months, I only need three months, but I need unconditional support from the state on any material.”

“In addition, I need the assistance of people who know a little about this, the more the better.”

Lin Weidong said seriously.

Lithography machine is not as simple as a photomapper.

“Well, no matter what, I will meet these two conditions of yours.”

Professor Li also gritted his teeth and said.

However, in this way, some of the engineers present were a little embarrassed.

Call them here, aren’t they here to develop new tanks?

How come this suddenly got into a lithography machine.

They don’t understand the technology in this area.

Professor Li naturally saw their thoughts, so he said, “Don’t worry. ”

“Although you don’t know much about the technology of lithography machines, the Middle East has just put forward a lot of suggestions for upgrading tanks.”

“Some of them are complex, we can’t do them, but those that are simple, I think there is no problem.”

“Before the lithography machine is finished, we finish the simpler designs to reduce the time later.”

“Yes!”

Everyone shouted at the same time.

Professor Li is right, they can’t do it if it’s difficult, can’t they do it simply?

Wouldn’t that be incompetent?

So after the meeting, the entire Academy of Sciences began to run rapidly like a clockwork machine.

Professor Li also mobilized materials and manpower for Lin Weidong.

Of course, Lin Weidong is not idle, even if the materials and personnel are not in place, but he can design some drawings first.

So just like that, a month passed in a hurry…
