The two girls were sitting on the sofa shoulder-to-shoulder side by shoulder and pursed their mouths, preparing to listen to Aunt Liang tell interesting technical and business stories.

I didn't expect that the story had just begun, and a guy suddenly jumped out and said, "I guessed it later that I don't need to continue talking, hahahaha..."

For Ning Wanfei, this is simply unbearable!

"Xiaoyuan, do you really understand?" Ning Wanfei's big black eyes were full of doubt.

"That's of course." Liang Yuan smiled proudly, trying to create a crushing feeling in IQ.

However, Ning Wanjia's expression as always looked like I knew Xiaoyuan would guess it early.

"Speak it out."

Maybe when he was a child, he lost too much of his bet. Ning Wanfei didn't care about someone's seemingly mean smile, and Liang Yuan's provocative eyes were vain.

"Feifei, you and Jiajia don't read the daily reports of Hong Kong-based power collectors, so they don't understand the key technologies in the integrated circuit production process."

Usually, he is a quarrel, but Liang Yuan’s patience with the two girls is completely super.

Liang Yuan first explained in detail the application scope and application prospects of electron beam physical vapor deposition technology, and then asked Li Yuanling if it was correct, and then talked about Yuanjia, the silent game behind this exchange.

Since electron beam physical vapor deposition is so awesome and has such a wide range of applications in the future, why should we replace the technology?

Speaking of this reason, it is related to the scientific and technological research and development level of the entire planet in the 1980s.

As one of the most top basic scientific research and development results on this planet, electron beam physical vapor deposition equipment has an extremely fatal disadvantage, which is that the cost of the equipment is too high, so high that the rich man like the United States is sucking his teeth and hurting.

If the equipment operation and maintenance costs are not considered, the US dollar can be called US dollar purchasing power in the 1980s. The cost of an electron beam physical vapor deposition equipment used in the field of aircraft engine blade coating is at least more than US$30 million, and the purchase price is close to US$40 million.

What does this mean? If it were replaced with American green paper in the new century, the equipment cost would definitely exceed 300 million US dollars, which means that this thing can be replaced with at least two F22 fighter jets that the US Air Force regarded as treasures.

The application of electron beam physical vapor deposition technology in the industrial field began in the late 1960s in the United States. At that time, local industrial countries such as West Germany, Japan, and the United States invested huge amounts of money to improve technology and equipment. The problem was that after massive capital investment, efforts to reduce equipment cost were completely failed.

In nearly two decades, none of the major industrial countries around the world, including the Soviet Union, have overcome the difficulty of reducing cost of electron beam physical vapor deposition equipment.

Will the rich man give up the entire forest because of a tree? Of course not. Turning in is an inevitable choice!

Although in the field of production and processing, the products produced by electron beam physical vapor deposition technology are the best and the highest quality, the overly high cost makes major industrial groups around the world stay away from it. After all, there is not a lot of surplus grain from landlords.

Therefore, low-cost alternative technologies such as atmospheric plasma spraying and vacuum plasma sputtering began to become popular in the international industry. The highest-quality electron beam physical vapor deposition technology basically became a high-tech to abandon further development in the mid-1980s.

Of course, since the electron beam technology is so high, even if you give up the development for five or six years, it is still the world's top industrial product processing technology.

The purpose of ge is very simple. If you dare to cut conditions with me, you will dig a big hole for you. I will see if you jump or not.

If a single crystal is replaced, it means that the Republic's independent project in the field of single crystals has failed. After all, with mature American technology ahead, no decision makers will abandon the technology that has been exchanged for huge costs.

Even if the Republic has completed the heat-resistant coating that matches the single crystal blade, the United States can still guess the specific data of the Republic's SAR Engine without much effort. When knowing the real data of the blade, guessing the engine performance through the combustion chamber working temperature is not a high-tech for experienced Americans.

If the heat-resistant coating is replaced, Ge can completely slap the electron beam physical vapor deposition equipment. After all, it is an international top-notch equipment. The original R&D investment will also be recycled, and then throw this bottomless R&D pit over. Whether the Republic jumps or not, it doesn't matter to Ge.

Of course, I would not believe that the Republic's scientific and technological community has the ability to improve electron beam physical vapor deposition equipment. So many Western companies have been helpless in their efforts for twenty years. Even if the Republic shouts that I can solve the problem, it can only be ridiculed.

In this exchange, Ge's small abacus was very good. You see, I have taken out all the top international technologies. I'm sincere enough. Anyway, no matter how you make Ge, it's very cheap.

The only shame is that Ge met a cheating rogue.

In 1995, the fourth year after the Soviets fell, the Ukrainian Barton Welding Institute, under the leadership of B.hen, an academician of the Soviet Academy of Sciences, successfully reduced the cost of electron beam physical vapor deposition equipment to less than ten million US dollars. The following year, the equipment cost was reduced to one fifth of the original one.

People who don’t care about the development of technology probably don’t know the great value of this news. Plasma etching equipment is the most important lifeblood of the modern wafer industry and the only technological choice. Without this thing, the development of chips is difficult.

If the Ukrainians had not had the long-lasting efforts in the electronic beam physical vapor deposition process, then even if the modern wafer industry can finally reach its former height, the time and cost would be extremely huge.

After the new century, the procurement price of nano-scale purple etching equipment was close to 200 million US dollars. Even if multiplying this number by five is an unbearable burden for the modern integrated circuit industry. Without the rapid development of the modern integrated circuit industry, there would be no Internet, no Apple, no social media, no games, entertainment, audio and video, no smart industry in the new era...

There are so many things that are not available. At least the history of the development and evolution of human society is destined to be rewritten.

You should know that in the era Liang Yuan is currently in, only political elites such as President Reagan, General Secretary Gorbachev, and Mrs. Thatcher, who are the highest-profile on this planet are eligible to enjoy face-to-face video calls in specific places.

In the view of Liang Yuan, who has experienced the baptism of the Internet tide, the speed and method of global information exchange in the 1980s were almost the same as those in primitive society. (To be continued.)
