The meeting room fell silent again.
After a long time.
Only then did someone discuss in a low voice.
"I don't study much. What is a maskless photolithographic machine?”
"I'm not sure."
"Don't look at me. How would I know?"
"This Vice President Su is always able to come up with new ideas for us.”
"To be honest, everyone, I wasn't too surprised just now because I'm already used to it.”
"Then why were your legs shaking just now?"
Elder Zhang and Elder Lin looked at each other.
Shock flashed in his eyes.
The people below did not know what a maskless photolithographic machine was.
They knew.
But this was only a guess and a suggestion.
He didn't even have the most basic theoretical support.
Su Chen actually said that he wanted to make it!
Su Chen continued,"
"Everyone, please be quiet."
"As we all know, the current photolithographic machine has already developed to 5 nanometres.”
"According to Moore's Law, it will be updated every two years.”
"It won't take a few years for the photolithographic machine to develop to 1 nanometre.”
" What about after 1 nano?"
"What do we do after that?"
"So we might as well bypass the western technology patents and make something they don't have!”
"At that time, we can directly ask them for patent fees!”
"Um, Vice President Su, I have a question. Can you answer it?”
"Speak."
"We've never even heard of the maskless photolithographic machine you mentioned just now.”
"Can you give a general explanation?”
"For example, what do you use for photolithographic?"
someone asked.
"Good question."
"Everyone knows that the current photolithographic machine uses an ultraviolet-light source to do photolithographic.”
"It is divided into violet rays, deep violet rays, and excited violet rays.”
"The 5-nanolithography machine uses extreme ultra-violet imprinting, which is also known as euv.”
"Extreme Ultraviolet light has a 13.5-centimeter wave length. It can engrave a 5-centimeter chip.”
"These ultra-violet rays are all called soft X-rays.”
"We use X-rays as the light source for the maskless photolithographic machine!”
Su Chen said.
"What are the advantages of X-rays compared to Ultraviolet rays?”
The people below continued to ask.
"A huge advantage."
" The X-ray's wave-length ranges from 0.001 nanometres to 10 nanometres. Smaller wave-lengths are also sharper, which also means that it can reduce the refraction of light waves, which is conducive to the formation of small and clear images.”
"And because the X-ray alignment is very good, it is 1:1 replication. The mask uses a low-stress Si: N film supported by a Si beam. There is a patterned layer on it as a mask layer.”
"The exposure method uses the immersion method, which can greatly increase the efficiency.”
Su Chen said.
The people below started whispering again.
"Vice President Su, what you said was great, even though I didn't understand a single word.”
"I'm also very confused, but when I was studying abroad, an old professor in our department mentioned using X-rays to do photolithographic.”
"And then?"
"And then? There was nothing else. By the way, this old professor's brain seemed to be a little abnormal.”
"Oh, I understand now. You mean only lunatics think like this?”
"I get it now. You're indirectly scolding Vice President Su.”
"I'm not, I didn't. Don't talk nonsense!”
"Ahem, everyone, stop arguing."
Mr. Zhang heard that the debate below had changed a little and immediately said.
Everyone quieted down.
Mr. Zhang looked at Su Chen.
" Little Su, let me say one more thing," he said." All the materials on the blue planet now have a refraction index of 1 and a high absorption rate for X-rays.”
"How are you going to solve this material problem?”
Su Chen smiled.
"I've thought about this question a long time ago.”
"It's very simple. With the design of the multi-layer film, the reflection rate of the waveband can be close to 70%.”
Mr. Zhang was stunned.
He was just asking casually.
He did not expect Su Chen to answer so quickly.
Mr. Zhang smiled bitterly.
He didn't know if Su Chen was right.
That was because he had never verified it before.
This kind of experiment had never been done internationally.
He looked at Elder Lin.
"Elder Lin, what do you think?"
Elder Lin was silent.
Everyone looked at him.
Su Chen also looked at him.
As long as Elder Lin nodded.
Su Chen's proposal would be approved.
Fully develop the maskless photolithographic machine!
After a long time, madness appeared in his eyes.
"I approve!"
"Just follow Su Chen's plan!"
"I won't be making the 14-nanolithography machine anymore!”
"If anything happens, I'll bear the consequences alone!”
After hearing this.
Su Chen was very touched.
He knew that his idea was crazy.
He did not expect Elder Lin to support him in developing this new type of photolithographic machine.
"Don't worry, Elder Lin, Elder Zhang, I won't let you down!”
"I will definitely make a maskless photolithographic machine!”
Su Chen said seriously.
"Hehe, I believe you.”
"You arrange the next step."
Elder Lin said with a smile.
Su Chen looked at the time.
"It's already noon. Everyone, take a break first."”
"Let's gather here at 1:30.”
Everyone dispersed.
Elder Lin and Elder Zhang stopped Su Chen.
"Little Su, come here for a moment."
"We have a few questions for you.”
Su Chen stopped and turned around.
"Elder Lin, what do you think?"
"Hehe, Little Su, you mentioned using X-rays to do photolithographic just now. There are so many benefits.”
"Then tell us about its disadvantages, technical barriers, and how you can solve them?”
Elder Lin said.
There would definitely be many technical barriers to using X-rays for photolithographic.
Moreover, it was very difficult to conquer.
Otherwise, both domestically and internationally, they would have long given up on the use of infrared rays.
"Elder Lin, I've already broken through the barrier of using X-rays.”
"In the process of my development, X-rays have a fatal flaw, which is that their energy is much higher than that of ultraviolet rays.”
"Then how did you solve this problem?”
"I used a low-energy electron X-ray.”
Su Chen replied.
Elder Lin and Elder Zhang fell into deep thought.
"Go eat first."
Old Zhang said.
"Alright, I'll go."
Mr. Zhang watched Su Chen leave.
"How do I submit the report to the higher-ups?”
"You directly said that you don't want to make the 14-nanometre photolithographic machine anymore?”
"We want to make a maskless photolithographic machine that is more advanced than the West?”
"Don't worry about that."
"Since I promised Little Su,"
"I'll report this matter to the higher-ups.”
"Sigh, you old man, don't you think you made a blind move?”
"You're already so old. Why don't you just work on the 14 nanolithography machine obediently?”
"Why do you have to make this kind of thing?"
"If you fail, your reputation will be ruined!”
Old Zhang sighed.
