Military Industry of Great Powers: Build the Strongest Flanker

He Zhenhua did it with full expectation.

He discovered that the benefit of the tungsten atom film is not only to isolate silicon and aluminum, but also to solve the problem of doping of the two materials with each other. In fact, it is also of extraordinary use in stabilizing the structure of aluminum wires.

Because aluminum and silicon have different physical properties, the aluminum and silicon layers can easily break under temperature changes, resulting in poor chip quality.

But now that there is a layer of tungsten atoms, this situation has been greatly improved.

“I feel like we can conquer the three-micron process!”

Professor He, I feel that even one micron can be tackled.

Well, by the way, where is Teacher Zhao?

He Zhenhua's student didn't recover for a moment and asked hurriedly: Teacher Zhao, which Teacher Zhao!

Zhao Guoqing, that young man who came just now!

Uh... A master is a teacher, okay!

He's in the chemistry lab!

He Zhenhua wondered: Didn't he go to the light-emitting semiconductor testing room?

do not know why!

Well, let's go and see!

…………

Compared with the laboratories of the 14th National University of Science and Technology, Tsinghua University's laboratories are like walking into the Grand View Garden with muddy legs.

Whether it is yttrium, rhodium, germanium... these materials, or various chemical instruments, it is quite complete.

Director Gao, it would be great if our 14th Institute built a laboratory like this!

Zhao Guoqing never forgets to ask Director Gao for any requests!

Gao Changming smiled. If he stayed there any longer, the good thing would fall into his eyes and he would not be able to pull it out.

National Day, our business trip has been long enough, we are going to go back in the next few days!

Zhao Guoqing thought for a while and nodded. The light-emitting semiconductor was finally completed. Although the results were somewhat different from what he had imagined, the overall result was still good.

National Day, I want you to think of a way to go back this time. Yesterday I heard the news at AVIC. The ministry has clearly issued a document asking military industrial units across the country to find ways to transform into civilian products. Next year's production tasks may be sharply reduced... …”

Gao Changming said that he was very worried. Next year's funding will be reduced by at least half. The problem of feeding hundreds of people in Institute 14 still needs to be solved. Moreover, there are still research tasks in the institute. The time is so tight. As a director, he is under great pressure. Very big.

When Zhao Guoqing heard these words, his spirits suddenly rose.

He walked up to Gao Changming and said, Director Gao, starting from next year, the country will no longer care about the life and death of our military industrial units!

Tsk! Gao Changming looked at Zhao Guoqing with a rather reproachful look in his eyes, and said, You can't say that, the country is also in difficulties. In recent years, many big projects have been canceled, such as synthetic ammonia, large chemical fiber, super large steel rolling... You are in the newspaper It’s not that I haven’t seen that economics is the priority in everything!”

Our 14th Institute must also contribute to the country's economic construction! Zhao Guoqing said righteously: Director Gao, the ministry should have given a lot of autonomy!

Do you have any ideas? Gao Changming said, As long as I can survive, I probably won't interfere!

Haha, what you want is autonomy.

Gao Changming said: The advantage of Institute 14 is the cooling system. Radar is not suitable for civilian use. The institute's intention is to build a refrigerator production line. We have a complete set of technologies for compressors!

...

Fortunately, we are not building a cold storage but making ice cream.

Director Gao, light-emitting semiconductors have great potential!

Gao Changming shook his head and said: National Day, you have done everything you said, but this lighting... I have also asked, after one wafer is completed, less than a hundred luminous crystals are qualified, but the phone bill and the materials are not enough. Manufacturing, cutting, and packaging cost more than 30,000 yuan. In total, this light bulb costs nearly 400 yuan. It is estimated that not many people can afford this thing...

Besides, it emits blue light. This blue light is good-looking, but it can't illuminate, and if you look at it for a long time, your eyes will hurt...

This is also due to the roughness of Qingda's technology. Originally, one chip could yield four to five hundred yuan. If the size of the chip was smaller, one or two thousand light-emitting transistors could be harvested, and the cost could be controlled within thirty yuan.

Price is already the biggest problem. Four hundred yuan can buy three bicycles. Who would buy light bulbs? Gao Changming himself is definitely not optimistic about it.

Zhao Guoqing said nothing. All along, as long as he could do something, there was no need to speak.

He took a set of test tubes and beakers and some experimental materials.

The alcohol lamp was lit and there was an infrared thermometer. This was a good thing. Zhao Guoqing drooled when he saw it. If it weren't for the size, he would have tried to slip it into his trouser pocket.

After a dazzling operation, the compounds in the test tube reacted violently, and finally produced a lump of yellow granular material.

National Day, what are you doing?

Zhao Guoqing poured out these particles and ground them into powder without raising his head, and said casually: Yttrium aluminum garnet YAG yellow phosphor powder!

?

What is this for?

Zhao Guoqing smiled and said: Director Gao, you will find out later!

Tsinghua University's laboratory also has an ultrasonic vibration grinder, which saves a lot of trouble. After crushing the powder, pour it into the volatile alcohol gel and stir it into a turbid liquid.

Zhao Guoqing carefully used a brush to brush the gel into a clean test tube, and then put it in the dryer. Repeated several times until a thin light yellow coating formed on the test tube...

alright!

Zhao Guoqing held the test tube and looked at it under the light. Although it was rubbed by hand, due to the proper method and good gel control, the entire coating was very even and there were no flaws according to visual inspection.

What's good, Teacher Zhao?

Teacher Zhao? Gao Changming looked left and right, where did Teacher Zhao come from? He suddenly remembered Zhao Guoqing, this kid...

Zhao Guoqing accepted it gladly. He was just a teacher, so he could afford it.

Professor He, why are you here!

The tungsten metal atomic deposition film has been made, and the effect is not very good. It is used to make the conductors of the gallium nitride tertiary crystal. It is now being tested...

Professor He, wait a moment and go to the light-emitting semiconductor testing room first.

...

Zhao Guoqing is too confident. What else is more important than process improvements and gallium nitride tertiary crystals? Doesn’t he want to know the results?

He Zhenhua followed behind depressedly. He really wanted to share the joy of success with Zhao Guoqing, but Teacher Zhao didn't seem to pay much attention!

Gao Changming was also confused. He had a vague hunch that the thin layer on the test tube must be something extraordinary.

When he arrived at the testing room, Zhao Guoqing took out five blue light semiconductors to be tested, connected them with wires in parallel, and put them in the test tube.

power ups!

It was no longer a cold, uncomfortable blue light, but a strong white light.

The brightness is too high, it lights up the whole room!

Zhao Guoqing looked at the ammeter and voltmeter and calculated the power of five blue light semiconductors connected in parallel.

How many?

Only thirty-five watts.

Zhao Guo shook his head. The power was still too small. Next time, he would see if it could be made into an array. Twenty LEDs would be combined into one, and a large heat sink would be added to the back. A high-power searchlight starting at 150 watts.

Gao Changming frowned, the bright light made him uncomfortable.

Thirty-five watts? Why does it feel brighter than the two-hundred-watt headlight on the tank?

Zhao Guoqing looked at Gao Changming. Well, Director Gao reminded him that the tank headlights can be used.

Of course, car headlights can also be used. LED headlights are high-end products.

The market prospects are very broad.

Zhao Guoqing vaguely remembers that Japan will hold a World Expo next year, and if he happens to take out the finished product for exhibition, he will definitely receive a lot of international orders.

This is earning foreign exchange, making money...
