Chapter 651 Airlines
Second, consider heat dissipation.

Light shining on the water will heat the water. This kind of thing is usually nothing, but the photolithography machine is an extremely sophisticated equipment.

The best way to cool water is to let the water flow, but once the water flows, air bubbles may form, so the shape and position of the water outlet must be strictly calculated.

Just to make pure water pumps and one-way valves for them, it almost killed Dongsheng Heavy Industries!

There is also the question of whether to submerge the entire bench, or just the lens...

I don't know how many times I have repeated experiments before I got a technically feasible and economically cost-effective result.

Entering the factory building, Yang Dongsheng glanced at Yang Miao next to him. Although he could only see his eyes, he could see that he was very interested in this place, "How is it, is this place clean?"

"En!" Yang Miao nodded.

They were also accompanied by several experts in the field of semiconductors in China.

Vice President Huang, also dressed in clean clothes, introduced while walking, "This lithography machine was manufactured in the early 80s. It uses the G-line of the mercury lamp with a wavelength of 0.436 microns, the aperture value is 0.3, and the resolution size is only 0.89 microns. Now through our The transformation has already reached the 0.35 micron process, catching up with the international advanced level in the mid-90s!"

Everyone nodded when they heard the words.

Vice President Huang continued, "I counted the similar equipment of the head office, subsidiaries, and affiliated companies. This alone can save the company's investment of 20 billion yuan and increase the annual output value by more than 5 million yuan! Let a A large number of old equipment have a new spring!"

Yang Dongsheng asked, "If you take out our most advanced lithography machine, how far can you do it?"

"This..." Vice President Huang was a little stuck at once, "Our company's most advanced lithography machine uses 193nm excimer laser light, which can be equivalent to 134nm in theory, but we don't have a lithography machine of this level yet. The ability to transform, and the etching machine and photoresist are not available, and only the technological transformation of the photolithography machine cannot produce high-process chips.”

Yang Dongsheng was still too impatient!

Semiconductor production is a typical barrel theory. What kind of product you can produce does not depend on how high the upper limit you can achieve, but on your lower limit.

Even if Yang Dongsheng can produce an ASML extreme ultraviolet lithography machine, he cannot produce chips with a process below 10 nanometers.

Yang Dongsheng patted Vice President Huang on the shoulder, "It took decades for the Americans and Japanese to reach the current level. How many years has it been for us? In the next 20 years, we can catch up to the international advanced level within 2 years. Even if we succeed!"

At this time, a thin-looking expert said, "Using the refraction characteristics of water is indeed a good way to achieve a technological leap, but the wavelength of light reaches 193 nanometers, and it will be strongly absorbed by water, have you considered the future? ?”

"Mr. Ni, immersion is only our transitional solution!" Vice President Huang was very respectful to this thin expert, "We are developing the next-generation light source technology!"

"Why do you add water, theoretically 193 nanometers can be equivalent to 134 nanometers?" Suddenly a voice obviously inconsistent with the surrounding atmosphere sounded.

Everyone looked at a figure next to Yang Dongsheng. Although they were all wearing dust-free clothes and could not be seen, it was obviously a child's voice just now. Many people knew that Mr. Yang's son was here today.

Yang Dongsheng patted Yang Miao's head, "Because the refractive index of pure water is 1.44, what is 193 divided by 1.44?"

"About 134!" Yang Miao thought for a while.

Coming out of the factory, Yang Miao jumped into the car without even taking off the dust-free clothes.

Yang Dongsheng thought, Yang Miao won't like this body, right?
Liu Xinyu returned to China from Russia.

The gold mine mentioned earlier has been taken down, and two coking coal fields and a piece of land have also been obtained in Kuzbass.

After reporting the situation of the mine, Liu Xinyu said again, "There is an airline company in Yakutia that needs to be dealt with. The Yakutia side asked us if we could take over and give us some mines as compensation!"

"What kind of airline?" Yang Dongsheng asked.

"A company mainly engaged in freight charter flights in Africa, Asia, Europe and the Middle East filed for bankruptcy at the end of 1999 and was handed over to the government in 2000." Seeing that Yang Dongsheng was noncommittal, Liu Xinyu continued, "Mr. Yang, this is how I think about taking over! After entering this company, we changed our business focus and mainly engaged in passenger and cargo services in the northern part of Russia. The land there is sparsely populated, the climate is harsh, and the demand for aviation is huge. Basically, there is an airport in a decent gathering area !"

Liu Xinyu glanced at Yang Dongsheng's face, and saw that Yang Dongsheng had no intention of objecting, and said, "Most of them are small airports, and large planes can't land! Although their An-2 has stopped production, we still have the same airports in China." Types of aircraft are being built, one is the Yun-12 of the Bingcheng Aircraft Factory, which can carry 18 passengers. Because it uses two Pratt & Whitney engines, the price is relatively high, each about 200 million US dollars; the other is The Yun-5B of the Shimen Aircraft Factory, a few years ago, each aircraft was only 30 RMB, which can accommodate 12 people! We can buy a few fewer Yun-12s and more Yun-5Bs. The Yun-5 is a copy of the An-2, the pilots over there are also easy to use!"

"Yun-12 and Yun-5B should not have obtained the Russian airworthiness certificate?" Yang Dongsheng asked.

"I also asked about this question! They said that as long as our planes fly with them and don't fly to Moscow, there will be no problem. They dare to fly on old planes that have been in use for decades, let alone Our new plane!" Liu Xinyu said with a smile.

"How dare they ignore Moscow?"

"Yakutia and Komi are republics, Chukotka, Yamal-Nenets, Dolgan-Nenets, Evenki, Koryak are autonomous regions with great autonomy! The people there Since ancient times, they have lived on hunting and herding. Coupled with the harsh climate, the tsar sent Cossacks to attack these places and suffered heavy losses. Many places were not even completely captured. The tsar had no choice but to adopt a soft policy, which gave a lot Self-government, it is said that during the Soviet period, the leaders of some places dared to take the table with Stalin, let alone now!"

Only then did Yang Dongsheng nod his head.

In fact, as soon as they proposed compensation with mines, Yang Dongsheng agreed in his heart. At worst, he would throw the airline away after the mines were taken away.

Moreover, Yang Dongsheng has another plan. The piston-type heavy oil aircraft engine is progressing smoothly, but the domestic airspace management is very strict. If it is inconvenient to test the flight in China in the future, the aircraft will be sent to Russia.

At this moment, Liu Xinyu glanced at Yang Miao, lowered his voice and said, "They also asked us if we could support them..."
