Military Industry of Great Powers: Build the Strongest Flanker

"Finally got this kid under control!"

Gao Changming took a long breath. In fact, he was also looking forward to what would happen if Zhao Guoqing had an internationally advanced semiconductor laboratory.

Of course, the first thing is to get the LED done.

Only when this is accomplished can we strive for other things.

I went through letters of introduction and the long green train ride.

On the morning of the third day, the two came to Beijing.

This time they slept in a berth, so they were not that tired. They went directly to the Qingda Guesthouse, put the gifts in the room, washed up, and had a meal.

"National Day, why don't we take a break and let's go again tomorrow!"

"Director Gao, why don't you take a break, give me your letter of introduction, and I'll go by myself!"

This young man's enthusiasm for work is enviable. How could Gao Changming abandon himself to lagging behind?

"Okay, I'll go in the afternoon!"

Director Gao poured the vegetable soup into the rice bowl, pulled the remaining rice grains into the soup, drank it all in one gulp, as if drinking, and burped with satisfaction.

"Walk!"

…………

Huaqing Microelectronics Research Center.

Like many units, the achievements and honors achieved by the research center are displayed on both sides of the entrance corridor.

What surprised Zhao Guoqing was that just three years ago, Huaqing Microelectronics Research Center developed the country's first distributed lithography machine with a process that can reach one micron.

"There is also a prototype machine in the institute. A total of more than 50 HQGK51 lithography machines have been built, and they are still being improved even now."

Zhao Guoqing was very curious and asked: "Professor He, what kind of light source does the HQGK51 lithography machine use?"

"We are using high-power high-pressure mercury lamps now. We are considering using krypton fluoride excimer lasers, using a 248-nanometer violet light source. The wavelength is twice smaller than that of mercury lamps, and the light wave interference is much smaller. It is expected that the process can reach 350 nanometers. .”

Zhao Guoqing nodded. In terms of manufacturing process, it has caught up with the level of the United States. Of course, technological progress is not only the manufacturing process, but also the level of automation. After all, for military use, price does not need to be considered.

But for civilian use, the price sensitivity is very high.

Zhao Guoqing asked some more questions about photoresist, etching equipment, and masks. In fact, Zhao Guoqing was surprised that the country can already produce these supporting equipment and consumables nationwide.

It is a pity that in the next few years, the lithography machine project will also be suspended and shelved.

…………

The foundation of Huaqing Microelectronics Research Center exceeded Zhao Guoqing's expectation, and the equipment is indeed internationally advanced.

High-precision electronic measuring instruments from West Germany, high-pressure meteorological molecule deposition furnaces, metal atom distillers from Japan, and built-in ultrasonic detectors.

The receptionist, Professor He Zhenhua, is also a veteran scientist. He studied at Moscow State University, and then went to East Germany for three years. Three years ago, he went to Japan for two years, and also went to IBM for an internship for three months. He just returned to China not long ago. long time.

Perhaps because of his rich experience, he is a bit arrogant.

Looking at the chip drawings, I started to find faults.

"Has your structure been proven? What does it do?"

Field effect transistors are still quite different from most current transistor structures. In fact, in this era, not many people have realized the advantages of this structure.

Gao Changming didn't understand technology, so the task of explanation fell to Zhao Guoqing.

Of course, Zhao Guoqing doesn't want to explain. Huaqing Microelectronics just needs to cooperate with the call made by the General Assembly Office.

"It needs to be kept secret when it comes to military affairs. Professor He, can you do it?"

"Can!"

He Zhenhua did not complain like Tong Yibo that the accuracy requirements were too high, and responded directly and neatly.

Gao Changming's face was full of flowers, and Zhao Guoqing was also very happy.

"Two points. First, a three-inch wafer can complete more than 1,700 transistors at a time. There is no way to guarantee that each transistor will pass. We can only use the median. The theoretical pass rate is about 17%. "

Zhao Guoqing nodded. The yield rate of 17% is indeed not very good, but it can be made no matter what.

"Second, we have not done the gallium nitride epitaxial layer noted above, and we still need to demonstrate it experimentally."

Zhao Guoqing said: "The pressure is 2,300 atmospheres, the temperature is 1,600 degrees, the upper and lower error does not exceed 5%, and the flow rate is controlled at 50 moles per second. According to this, the deposition thickness per second is about 17 nanometers, which is about It only takes three hours and fifteen minutes.”

He Zhenhua looked at Zhao Guoqing with some confusion.

"Have you done this experiment?"

Zhao Guoqing nodded and sighed deep in his heart. Intellectual property rights are not valuable in this era. Just the set of experimental data just now could be sold in the West for one million US dollars. If he had to explore by himself, the trial and error would require more than one hundred consumables. Ten thousand U.S. dollars.

"Okay, then let's do what you said first, and if it doesn't work, we'll talk about it later!"

"good!"

"Professor He, can we go in and visit?"

"It's a dust-free environment inside. If you're not familiar with the equipment, don't go in!"

"..."

"Can I visit the prototype of the lithography machine in your research center?"

He Zhenhua said impatiently: "You should go back to the guest house and rest first. I'll call you when I'm ready!"

Soon only Director Gao and Zhao Guoqing were left in the conference room.

"Go back, it's National Day, that's fine, it saves you the trouble."

Zhao Guoqing shrugged helplessly. Huaqing Microelectronics did not mention money when helping him this time. What could he say?

"A little regretful!"

"You!"

Gao Changming hurriedly pulled Zhao Guoqing away. The young man's eyes were filled with stars. He was really worried that if Huaqing Microelectronics extended an olive branch now, he would run away immediately.

Hey, Director Gao, you are worrying too much.

Zhao Guoqing is envious, but Huaqing Microelectronics does not engage in radar.

Director Gao believes: Zhao Guoqing is an expert in semiconductors.

Zhao Guoqing disagreed. His side business was semiconductors, and his main field was radar, which he had been working on for forty years.

But if you want to develop radar, semiconductors are an insurmountable threshold.

"On National Day, it's a rare trip to Beijing. This time we also want to relax, see the Forbidden City, and climb the Badaling Great Wall!"

"No, Director, I have something else to do!"

"What's the matter, National Day? You don't want to play with the old man at this time, right?"

"Director, where are you thinking!" Zhao Guoqing said: "It's rare to come to Beijing, so Huaqing Microelectronics should do more work for us. It doesn't cost money anyway!"

"..."

Gao Changming didn't know what Zhao Guoqing wanted to do!

"Director Gao, Huaqing Microelectronics can make chips with a one-micron process!"

"this……?"

What’s wrong with being able to make chips? What kind of chips can we let them make? This Xiao Zhao... is going crazy again.

"Director Gao, you also saw it in the internship office!"

"Radar fire control calculation circuit diagram?"

"I was using logic transistors and trying to rephrase the design idea!"

"..."

"You are not joking about National Day!"

Director Gao felt like he didn’t know what to say!
