Big Country Intelligent Manufacturing

"Xu Zhenming is a layman, can you know the technical principle of this lithography machine?"

"The icing on the cake is not as cost-effective as sending charcoal in the snow. I'd better wait until the end to show my cards."

After hesitating for a long time, Liang Songsong still held back, and did not speak out his judgment and assumptions.He turned his face away and began to arrange the experimental procedures of his group.

At this time.

Professor Hao Ning’s team members have entered the state, and have adjusted various instruments such as the laser energy tester, laser spectrum analyzer, and laser head focal length tester, and can enter the test state at any time.

Seeing that the preparations of Professor Hao Ning's group were ready, Liang Songsong stretched out his hand and stroked the shiny hair on his head, and ordered with a serious expression: "Professor Hao, let's start the experiment. The first step is to test the attenuation rate of laser energy. "

"Start the test! Adjust the energy tester to the automatic adjustment operation state, and test a set of data for each height of 0.001 mm." Hao Ning glanced at Liang Songsong, and then entered the working state.

The energy test of the laser optical path system is very difficult, and the energy consumed by the laser in the air will be attenuated by one data level for every 0.001 mm difference in space height.The final value of laser energy will affect the intensity of laser exposure and the accuracy of the physical circuit diagram of chip lithography.

This is why Liang Songsong put this test project in the first step.But he was not in a hurry at this time, as if he already knew the data after the test.

"The data of the first node is normal, and the laser energy attenuation is lower than the data level of 0.009."

"The data of the second node is also normal, and the energy attenuation is lower than the data level of 0.0095."

"The third node has more beautiful data..."

As the laser energy test target keeps dropping, the data on the workstation monitor keeps beating.Hao Ning and others looked at the data, and unconsciously said the results of the test data.

These data are all within the specified range, indicating that the quality of the laser light path system produced by the Miguo is very stable.

"The quality of Laomi's products is indeed very good."

"Who can say no. Small size, high power, low noise, and very low power consumption. It would be nice if the laser optical path system we produce can meet this standard."

"Our laser generators cannot do this. The machining accuracy is not as good as others, the processing accuracy of optical instruments is not as good as others, and the quality of optical materials is not as good as others. What can we compare to others?"

Hu Lei and Li Feng, two old men, shook their heads helplessly while watching the monitor.While admiring this laser light path system, they were a little helpless.

As the first generation of optical engineering experts trained by Huaxia, they have a sense of group honor more than most Huaxia projects.In their youth, even the most common military telescopes in China imported from East Germany and the Czech Republic.

It is precisely because of the efforts of their generation that China’s ordinary optical instruments have become self-sufficient.This is also a remarkable innovation.

In terms of optical products, the German Zeiss company has always been a leader and has never been surpassed.

Zeiss has specialized optical research universities and research institutes, and the accumulated research resources cannot be estimated. Why can the average country surpass it at will?Unless, like the White Bear Country and the United States, step into Germany as a victor and take away the available research materials.

Thinking of so much, Hu Lei's heart has to be balanced a lot.He retracted his gaze and looked at the really busy young assistants.

"Fortunately, our group company pays attention to the echelon construction. These young people are the future of our country's optical instrument science." Hu Lei was in a much better mood, and a smile appeared on the corner of his mouth.

"Mr. Hao, the first test has been completed. Do you want to do the test again?" At this moment, the technician in charge of operating the laser energy tester turned his head and asked Professor Hao Ning.

This test consumes consumables such as masks, photolithography reagents, intermediate adjustment reagents, and optical lenses on the laser target surface, which costs a lot.The cost of doing the test again will not be less. Of course, Xiao Zhang, the technician, has to seek the advice of Professor Hao Ning.

Hao Ning didn't even think about it, and said casually: "Of course we have to test. Our team must be cautious in doing things. Like this kind of routine test, it is best to do three times to get the trust of the experimental data."

Having said this, he suddenly remembered that this experiment was led by Liang Songsong, and he could not draw any conclusions.So, he looked back at Xiang Liang Songsong.

From the bottom of his heart, Liang Songsong believes in the quality of American products.He smiled confidently at this time, "Intel's quality inspection procedures are stricter than ours, and the products transferred from their company must be no problem. I don't think there is any need to experiment."

While talking, he smiled and looked at Wanning Gu and Xu Zhenming who were squatting on the ground.,

"Mr. Wan, the data tested by our group has come out. The output power of this laser optical system is very stable, and the attenuation rate in the air is fully up to the standard. My opinion is that this test can be ended and the next test work can be carried out. "

"Yes, Laomi's products are good, compact, precise, large and stable."

"It would be great if our laser light path system could achieve this step."

After Liang Songsong reported the work, Hu Lei and Li Feng, two old experts, echoed with emotion.

At this moment.

Professor Hao Ning held different opinions, "Lao Hu and Lao Li, our current focus is not to develop a new generation of laser light path system, but to develop this micron laser energy tester. Without this kind of precision testing instrument, we will no longer It’s not easy to go back."

"Hey... this is the truth."

"The micron-level optical energy tester involves all aspects of precision machinery, precision control, precision sensing, and cutting-edge special materials. It is not small, Mr. Hao."

Hu Lei and Li Feng were driven by Professor Hao Ning, and they turned to pay attention to the difficulties in their own jobs.And this difficulty is exactly the problem faced by the current Huaxia researchers.

The technical reserves of Huaxia are weak in all aspects, and when put together, they are even weaker.The difficulty of doing this kind of system engineering can be imagined.

Liang Songsong has been to Yiming Group for a long time and has a good understanding of the status of China's technical reserves.He is not optimistic that someone in the country can make a cutting-edge optical energy tester.

"Ok…"

Therefore, Liang Songsong smiled disapprovingly, the kind of smile with a strong nasal sound.Although he was deliberately covering up, he still failed to hide his disdain.

"Even if it is difficult, we have to build our own set of optical testing equipment. Otherwise, how do we develop the fourth-generation lithography machine, or the fifth-generation lithography machine?"

Perhaps feeling Liang Songsong's disdain, Professor Hao Ning waved a little excitedly.Then he looked at Xu Zhenming and thought that the laser optical system should be tested twice according to the predetermined test procedure.
