Chapter 245 Sanctions? Then get an X-ray lithography machine!
[The FBI suddenly mobilized and caught the undercover agent who had been hiding there for ten years.]
[FBI caught an undercover agent, suspected to be Chinese?]
[Recently, the FBI caught an undercover agent and committed suicide the night before the trial out of fear of guilt]
[Undercover suicide? Or is there another reason? 】
…
Related news pieces began to compete for headlines.
News like this has to attract people's attention, undercover?
Or is there an undercover agent who commits suicide out of fear of crime?
Everyone who saw this news was shocked.
In China, there are many people discussing on the Internet, but they don't know whether this undercover agent is really one of theirs.
After all, these are just news coming from abroad, and no one knows the details.
Compared with this political matter, people in the semiconductor industry are more concerned about another piece of news.
Foreign sanctions technology has added several more, one, quasi-laser transmitter.
This thing is a very necessary component in the light source of the lithography machine.
It mainly uses a carbon dioxide laser to emit extremely high-energy laser, outputting a laser beam with an average power of more than 30kW, and the pulse peak can reach up to several megawatts. Then such a high-energy laser hits the tin beads that are constantly dripping from above, and then
It emits extreme ultraviolet light with a wavelength of 13.5nm.
If you want to achieve such a high power on a carbon dioxide laser, ordinary technology is completely unfeasible, and China's current carbon dioxide laser cannot meet this requirement in terms of power. What you need to know is that this power will ultimately affect
Actual power of EUV light source.
If the EUV light source does not have enough power, the impact on them will be very large.
In addition, several other important sensors in EUV light sources have also been sanctioned.
In this way, if they want to develop lithography machines, they must first achieve breakthroughs in these aspects, otherwise the light source cannot be developed and everything will be in vain.
All of a sudden, there was another wave of negative voices in China’s semiconductor industry.
If they continue to do it one by one, how long will it take them?
By then, foreign countries may have already found a technology that can break through existing photolithography machines.
In addition to these things related to photolithography machine technology, foreign countries have also imposed sanctions on the photomask, one of the raw materials. The photomask is an equally important thing in the photolithography process. Only through the mask
, extreme ultraviolet light can achieve direct lithography.
Nowadays, mainstream masks use quartz as a material, and the main sanction project this time is this quartz material. The production process of this quartz material is very difficult, and China has always needed to import it from abroad.
But now that they can no longer buy quartz materials, it means that all domestic mask manufacturers have been directly scrapped.
After these few moves, the domestic semiconductor industry chain was once again hit hard.
…
"Damn, those foreign devils must have thought up bad things after seeing us develop top-notch mirror polishing technology. They are so shameless!"
In Lin Xiao's office at Dingguang Research Institute, Luo Ming said angrily.
But Lin Xiao just sat quietly at his desk, thinking about the problem.
Luo Ming was still angry and continued: "They also arrested an undercover agent, claimed to be one of ours, and then publicized that he hanged himself in the prison? Obviously they were just to demonstrate for us again! Could there be a rope in the prison?
Did someone hang himself?”
"Bah, disgusting!"
But hearing what Luo Ming said, Lin Xiao frowned: "Undercover? Hanging himself?"
"Yes, all the news from abroad has come back, it's simply too abominable!"
Luo Ming said extremely angrily.
But Lin Xiao suddenly stood up.
Undercover?
And then it happened to be discovered at this time?
He has a good memory and strong association skills. He immediately thought of the Wolf Prize.
Didn't someone from the National Security Bureau tell him, receive the information, and ask him not to accept the award?
At that time, he also thought about where the information came from, but he didn't think too much about it. Now think about it, is it because there was such an undercover agent who brought the information to them?
He couldn't help but breathe quickly. If the undercover agent was really one of theirs, he was really discovered because of him.
Then he...
Next to him, Luo Ming saw that Lin Xiao had not panicked after hearing that he had been sanctioned. However, when the undercover incident was mentioned, he became like this. He couldn't help but wonder: "Professor Lin, what's wrong?
"
Lin Xiao waved his hand and said solemnly: "I need to make a call, please."
Luo Ming knew that Lin Xiao wanted him to avoid it, so he nodded, "Okay, go ahead and fight. If anything happens, just tell me."
"Um."
Lin Xiao nodded. After watching Luo Ming leave, he took out his mobile phone, thought about it, and finally found the number of the national security officer who called him. Although it had been several months, he still remembered the phone number.
When did I call him? I looked through my address book and found it.
Then, he dialed.
After about a while, the call was connected, and the other party's voice was obviously surprised: "Is it Professor Lin?"
"It's me, are you a comrade from the National Security Bureau?"
"Yes, what's the reason you called?"
"Is the undercover guy who was caught on the news the same person who helped me in the first place?"
Lin Xiao asked, feeling very nervous.
"Uh... don't think too much about this, we won't send spies abroad."
This national security staff member gave a very official answer.
Lin Xiao did not give up and still asked: "I know, but I just want to confirm whether he is someone who has helped me and will not involve secrets. Of course, it is impossible for me to leak such secrets."
Hearing what Lin Xiao said, the staff member was speechless for a moment, and then said: "Professor Lin, please wait a moment, I'll ask my leader, and I'll call you back later."
"Okay, please."
Lin Xiao said.
Then he hung up the phone and started waiting.
While waiting, he could only hope in his heart that the other party would give him a negative answer, but he thought too much.
But there was always an uneasy feeling in his heart, which made him think that it was very necessary for him to confirm this matter.
In this way, time passed quickly, and finally, his cell phone rang again.
He quickly connected and asked, "How is it?"
The other party said: "Professor Lin, I can only tell you one thing. The person who helped you did hang himself in prison recently. But whether he is the person in the news, I'm sorry, I can't reveal it to you."
Lin Xiao fell silent.
The other party did not admit the connection between the two, simply because it was confidential and could not be disclosed.
But obviously, the other party has already hinted.
He hanged himself in prison recently. Besides this person, who else could it be?
When the other party heard that he had not spoken, he said: "Professor Lin, if there is nothing wrong with you, I will hang up. To be honest with you, we are going to pay homage to a fallen comrade later. Just like you,
We are all heartbroken."
Lin Xiao finally spoke at this time: "The person who helped me, is his family okay? Can I do anything for his family?"
"Don't worry about this. When he helped you, he helped us, and we have corresponding measures."
"Okay, then... thank you."
"Haha, it is our mission to protect important scientists like you. We all have a sense of destiny. You don't need to be too sad. If possible, what we look forward to more is that you can be in your career.
Do more deeds, then our mission will be meaningful."
"I will."
"Well, I won't disturb you anymore, goodbye."
"goodbye."
The call is over.
Lin Xiao held the phone and did nothing.
There was silence in the office.
It wasn't until a while later that he finally came to his senses, but he closed his eyes.
"system."
"Using the [Mechanical Overall Optimization Guidance], for the current EUV lithography machine, the optimization direction is, X-ray lithography machine, the overall idea is to use the direct writing advantages of the
scaling effect, enabling mass production.”
"Optimization in progress, please wait..."
Lin Xiao opened his eyes again.
The dead are gone, the living are like this.
The National Security staff member said it very well. They expect him to make more and more important achievements, which will make their mission meaningful.
Then he couldn't live up to their expectations, especially the comrade who died because of him.
If foreign countries want to impose sanctions on EUV light sources, then they will switch to X-rays.
If foreign countries want to impose sanctions on masks, they will build maskless X-ray lithography machines.
He will not be angry because of what his enemies do, he will only make those enemies regret it.
