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

Which Cheng thought that the story had just begun, and a guy jumped out and said, I guessed that there was no need to continue to tell it, hahahaha.......

For Ning Wanfei, this is simply unbearable!

"Xiaoyuan, do you really get it??" Ning Wanfei's big black eyes were full of suspicion.

"Of course. Liang Yuan smiled proudly, trying to create a sense of crushing IQ.

It was Ning Wanjia's same expression as always, I knew that Xiao Yuan would guess it early.

"Speak up and listen. ”

It was about when she was a child that she lost too much in bets, Ning Wanfei didn't care about someone's cheap-looking smile, and Liang Yuan's provocative eyes were lost in vain.

"Fei Fei, you and Jiajia don't read much of the daily reports of Gangji Collector, so they don't know about the key technologies in the production process of integrated circuits. ”

Usually a bickering is a bickering, and 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 the silent game behind the exchange between Yuanjia and GE.

Since electron beam physical vapor deposition is so powerful and widely used in the future, why does GE need to replace the technology?

Speaking of this reason, it is related to the level of scientific and technological research and development of the entire planet in the 80s.

As one of the top basic science research and development achievements on this planet, the electron beam physical vapor deposition equipment has an extremely fatal shortcoming, that is, the cost of the equipment is too high, so high that the local tyrants like the United States are sobbing their teeth and flesh.

Excluding the cost of equipment operation and maintenance, a set of electron beam physical vapor deposition equipment used in the field of aero engine blade coating costs at least more than $30 million in terms of the purchasing power of the US dollar in the 80s. The purchase price is close to $40 million.

What kind of concept is this, if it is replaced with the American green paper of the new century, the cost of equipment will definitely exceed 300 million US dollars, which means that this thing can at least be replaced with two F22 fighters that the US Air Force regards as treasures.

The application of electron beam physical vapor deposition technology in the industrial field began in the late 60s in the United States, when the local tyrant industrial countries on the planet such as West Germany, Japan, and the United States invested heavily in improving technology and equipment. Efforts to reduce equipment costs have failed completely.

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

Will the local tyrant give up the entire forest because of a tree, of course not, it is an inevitable choice to turn in!

Although in the field of production and processing, the quality of the products produced by the electron beam physical vapor deposition technology is the best and the highest quality, but the high price makes the world's major industrial groups stay away from it, after all, the landlord's surplus food is not very much.

As a result, it is similar to atmospheric plasma spraying. Low-cost alternative technologies, such as vacuum plasma sputtering, began to gain traction in the international industry, and the highest-forcing electron beam physical vapor deposition technology basically became a high-tech technology that abandoned further development in the mid-eighties.

Of course, because the forced price of electron beam technology is too high, even if it gives 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, dare to cut the conditions with me, dig a big hole for you, and I will see if you jump or not.

If you change to a single crystal. It means that the Republic's independent projects in the monocrystalline field have failed, after all, there is a mature technology from the United States. No decision-maker will discard technology that has been traded for a great deal of money.

Even if the Republic gets the heat-resistant coating that matches the monocrystalline blades, for the United States, it still doesn't take much effort to guess the specific data of the Republic's new aviation engine, and in the case of knowing the real data of the blades, guessing the engine performance through the operating temperature of the combustion chamber is not a high-tech for experienced Americans.

If the heat-resistant coating is replaced, GE can completely slaughter the electron beam physical vapor deposition equipment, after all, it is the world's top equipment. The original R&D investment is also to be recycled, and then this bottomless R&D pit is thrown over, whether the republic jumps or not, it doesn't matter to GE.

Of course, GE will not believe that the Republic's scientific and technological community has the ability to improve electron beam physical vapor deposition equipment, and the efforts of so many Western NB companies for 20 years are still helpless, even if the Republic shouts that I can solve the fear, it can only be ridiculed.

In this exchange, GE's small abacus beat the thief. You see, I have taken out the top international technology, which is sincere enough, anyway, no matter how you get GE, it is cheaper and cheaper.

The only pity is that GE has encountered a scoundrel who cheats.

In 1995, four years after the fall of the Soviet Union, the Patton Welding Institute of Ukraine, under the leadership of B.A. Movchen, an academician of the USSR Academy of Sciences, succeeded in reducing the cost of electron beam physical vapor deposition equipment to less than 10 million US dollars, and the equipment cost was reduced to one-fifth of the original in the following year.

People who don't care about the development of science and 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 it is also the only technical choice, without which the pace of chip development is difficult.

Without the persistent efforts of the Ukrainians in the electron beam physical vapor deposition process, the time and cost of the modern wafer industry would have been enormous, even if the modern wafer industry had finally reached the heights it once had.

After the new century, the purchase price of nano-level violet etching equipment is close to 200 million US dollars, even if this number is multiplied by five, it is an unbearable burden for the modern integrated circuit industry, without the rapid development of the modern integrated circuit industry, there will be no Internet, no Apple, no social media, no new era of games, entertainment, audio-visual, no intelligent industrial .......

There are simply too many things to without, at least the history of the development and evolution of human society is destined to be rewritten.

You must know that in the current era in which Liang Yuan lives, only political elites such as President Reagan, General Secretary Mikhail Gorbachev, and Margaret Thatcher, who are the most powerful on the planet, are eligible to enjoy face-to-face video calls in specific locations.

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 80s were almost the same as those of primitive societies. (To be continued......)
