The working principle of immersion lithography machine is also simple. In fact, it is to add a layer of water in the middle of the original dry lithography machine, and then use the refraction of light to improve the working accuracy of the dry lithography machine that has reached the limit by more than ten times.
In short, it is... Well, we don't need to know the damn working principle. We just need to know that the first immersion lithography machine in the world is working now.
Although this is only a semi-finished product, there is no doubt that it is making history.
However, the process of making history is actually quite boring, because the whole process is very slow and takes about 20 minutes.
The process itself is more boring. If you look at it with the naked eye, you can only see a light. The whole engraving process is not seen at all unless it is through a special instrument.
But there is only one device. In Ni Guangnan's hands, boss Jia can only see such a light. There is no change in 20 minutes. Boss Jia can't even know how the experiment is going.
Of course, with the passage of time, boss Jia gradually saw the clue, because the happy researchers in the laboratory had dimmed their expressions, and their faces were full of disappointment and pain.
There is no doubt that this experiment destined to go down in history ended in failure.
Well, it seems that the aura of our boss Jia's protagonist has not taken effect this time.
"What's the problem?" boss Jia asked immediately after Ni Guangnan and Lin benjian came out together.
"The whole monocrystalline silicon is destroyed!" Ni Guangnan sighed. "There is nothing engraved on it, not even a transistor. It's all chaotic. We failed!"
"I think it's a big event. Failure is the mother of success. What's this?" boss Jia smiled and comforted.
Although the failure is disappointing, boss Jia still has a lot of time and money. Everything is not in a hurry!
"In fact, we have failed thousands of times, but this time is quite different!" Ni Guangnan's expression was even worse, and his wrinkled face even wrote the word confusion.
Boss Jia certainly knows that this failure is very bad, because since Ni Guangnan excitedly asked him to visit the experiment, it shows that Ni Guangnan is at least 90% sure that the experiment will succeed, otherwise there is no reason to call his big boss.
Are you ashamed to watch them?
But the fact is that the experiment failed, which is undoubtedly a great blow to Ni Guangnan.
"The most important thing is that we can't find the reason for the failure!" Lin benjian said. "We have calculated everything, and all the data have no problem. I even think we have a 99% success rate, but we failed. Now we don't even know the reason for the failure!"
"So..." boss Jia smiled. "If you can't find it now, it doesn't mean you can't find it in the future. Maybe some data is wrong, or maybe there is dust. Everything is possible, isn't it?"
"You're nonsense!" Ni Guangnan turned his eyes. "Come on, let's see that we're embarrassed. You have nothing to do. You can go back and continue to be your big boss and get your golden dragon award!"
"No, I've just come, so I'll drive me away. I'll look at the experimental records before I go!" boss Jia said helplessly.
"What experimental records do you read? I'm afraid you can't even understand the basic publicity..." halfway through Ni Guangnan's speech, he suddenly became mute. He suddenly remembered that boss Jia, a student, didn't take it through the back door, but an apprentice who really passed the exam.
Boss Jia himself is actually a super genius no less than Liu Nian. Even graphene was discovered by boss Jia, but this guy's commercial achievements are so dazzling that he ignores boss Jia's design of a talented scientist.
"Let's see. Maybe we'll send you as a cobbler!" Ni Guangnan nodded, then took boss Jia to change his clothes and re-enter the laboratory.
At this time, the people in the laboratory had gone a lot. When they saw boss Jia changing clothes, they were curious. These people came in again.
Boss Jia went straight to the test equipment, saw the experimental monocrystalline silicon, and then directly observed the morphology of the monocrystalline silicon with an electrical microscope.
As Ni Guangnan said, although many lines are indeed engraved on this monocrystalline silicon, all lines are irregular, like chaotic wool.
Unlike qualified chips, as like as two peas, the transistor will be printed on one side after another.
At the first sight of this single crystal silicon, ordinary people can conclude that it has failed. However, boss Jia has been carefully observing the shape of the whole single crystal stack and the lines on it for a long time, for about five minutes, and constantly measuring data.
"Why, did this guy really find out?" Ni Guangnan was surprised to see boss Jia's ecstatic state.
The researchers around were also very surprised. Can Chairman Jia pretend like this? He just pretended to look at it. What are you doing so seriously!
Pretend as if you can understand it. Is it interesting?
Of course, although these researchers murmured in their hearts, on the surface, they still looked at boss Jia with worship and respect. After all, people pay for it and they work.
"How's it going? What's the result?" Ni Guangnan asked curiously after boss Jia finally removed his eyes from the electron microscope.
"Of course, I made a great discovery!" boss Jia smiled.
"What great discovery?" Ni Guangnan asked in surprise.
"That is, in fact, our experiment did not fail, but our experiment was successful!" boss Jia opened his mouth and said, "Congratulations, my teacher, you have made history and successfully made 70nm chips by using immersion lithography technology!"
"Are you teasing me?" Ni Guangnan heard that he wished he had a ruler at hand and could ruthlessly come to boss Jia's palm. This guy dared to deceive his teacher.
"I'm not teasing you!" boss Jia pointed to the picture of the optical microscope. "I just measured. Although none of the transistors succeeded, all the lines were at the level of 70nm."
"This means that we have succeeded. We can print 70nm lines on monocrystalline silicon, but we still lack some problems in controlling the lines!"
"You're a strong word..." Ni Guangnan wanted to accuse boss Jia of being unreasonable, but after boss Jia's advice, Ni Guangnan found that boss Jia seemed to be right. The level of 70nm has indeed been reached. The biggest obstacle to the dry lithography machine has been broken. What they encountered was just the problem of unable to control the lines!
