"Oh, how do you say?"

Mu Jingchi had a smile on his face, "I'm not afraid of your jokes when I say it, I also thought about moving to the direction of electronic engineering materials at first, but finally gave up." ”

"Why did you give up?"

"It's so hard. ”

As he spoke, Mu Jingchi also felt a little emotional.

Mu Jingchi had indeed thought about the change of direction before, but he didn't say it on purpose, and he did give up in the end. There is really no way, the entire semiconductor industry is even more difficult than where Mu Jingchi is now.

To make a breakthrough in the semiconductor industry, it involves breakthroughs in key technologies and key materials in the entire industrial chain, and there are too many things involved.

Even if Mu Jingchi can make extremely outstanding achievements in a certain aspect, which is reflected in the entire semiconductor industry chain, although its influence is not enough to directly close the gap between China and foreign countries.

The entire semiconductor industry in China involves economic considerations, even if it is an annual chip import of 300 billion US dollars, but it is still a commercial matter.

But what Mu Jingchi is doing now is slowly infiltrating into the national defense and military industry, and compared with the commercial economy, the political importance of the national defense and military industry is stronger.

"My idea is to help improve our country's military strength, and when our military strength is strong, some foreign restrictions will slowly be opened, and then maybe you can buy it with money. ”

To truly catch up with the United States in China's semiconductor industry, it is not possible to do it in a short time, and what is lacking is talent. It is not the kind of talent who has come down from the undergraduate, but the key core talent who is really engaged in research and development and can do innovative research and development.

Hearing Mu Jingchi's answer, Shen Fangnan also laughed, "It can't be said that there is no such possibility, this is also a road, but the road of self-research still has to be taken." ”

"Of course, I can only do my best. ”

In fact, Mu Jingchi is still very optimistic about the path he has chosen, and with systematic help to provide extraction knowledge, this path is really possible.

In the current world situation, as long as China can compete with the United States, Europe is a loose alliance and does not have the conditions to challenge the US hegemony.

The United States has three major tools in its hands, military power, financial power, and semiconductor power.

In the current international relations, unless the United States wants to directly start a war with China, the so-called military strength can only sow discord and sow discord in the internal affairs of the China region.

Mu Jingchi doesn't know much about finance, and only knows a dollar settlement, which should also be based on the national strength of the United States.

Finally, semiconductors are more powerful in the entire international business environment.

Most of the world's semiconductor profits have flowed into the United States, and even some European semiconductor companies dare not eat too much of the meat of the United States.

At this glance, it is obvious why the United States wants to suppress Huaxia's semiconductors.

Because the cheese of the United States was moved!

Mu Jingchi intervened in the country's strength with national defense and military materials, and China's military strength was improved, so there were more things that could radiate and influence.

If the previously very strict treaty can be loosened, coupled with the improvement of Huaxia's local scientific and technological strength, then Huaxia's scientific and technological strength can also slowly increase.

And if Mu Jingchi can still come up with black technologies such as nanomaterials, nuclear fusion, and even anti-gravity in the medium term, then he will move the dollar settlement and promote the RMB settlement.

At that time, the military, finance, and technology will be able to compete with the United States.

If Mu Jingchi continues to exert his strength, then he will enter outer space.

At that time, it was the time when China got rid of the United States.

The idea is such a general idea, the relationship between real countries and countries and countries must be extremely complicated, but the general direction of Mu Jingchi is to prepare to go this way.

First get the country's national defense and military materials, then open the black technology inside the earth, and finally open the black technology of outer space.

As for being able to achieve it, it depends on whether the system is powerful and its own ability level.

"In fact, there is no need to be so pessimistic, our country has actually made a lot of progress now. Peng Xiaojie's words are still very gentle, and he is still very optimistic about the development of Huaxia.

"Wuhan Xinxin, a subsidiary of Tsinghua Unigroup Group, has achieved a breakthrough of 128-layer stacked 3D NAND FLASH using its own patented Xtacking architecture, and it will be able to be mass-produced in a year or two, and it will be able to seize the international market at that time. ”

"Everything comes little by little. ”

Peng Xiaojie and Shen Fangnan have known each other for a long time, and the relationship between the two is very good, so they can understand Shen Fangnan's anxiety, after all, they were beaten if they fell behind.

The first beating was in the last century, and it took a toll of life.

The second attack was the high-tech crackdown of the United States in recent years, which caused a loss of hundreds of billions of dollars.

It is impossible not to take it to heart.

"Of course I know what you said, but when it comes to this, I will inevitably be a little unwilling. Shen Fangnan picked up the water cup on the coffee table and took a sip of tea by himself.

Seeing Shen Fangnan's expression, Mu Jingchi didn't continue to talk about this, it only added to his troubles.

"Brother Peng, how is your research?"

Before Peng Xiaojie could speak, Shen Fangnan spoke first, and looked at Peng Xiaojie with resentment in his eyes, and then faced Mu Jingchi and said, "His research is better than mine, and it is going much smoother." ”

"Now our country is already at the international level in the third generation of semiconductors, although there is still a gap with Japan, Europe and the United States in some aspects, but it is not big, and it is smooth to catch up. ”

When many people talk about semiconductors, the first thing that comes to mind is the silicon chips on mobile phones and computers, but that is the first generation of semiconductors.

The second generation of semiconductor materials mainly refers to compound semiconductor materials, such as gallium arsenide (GaAs) and indium antimonide (InSb), and ternary compound semiconductors, such as GaAsAl and GaAsP.

There are also some solid solution semiconductors, such as Ge-Si, GaAs-GaP, glass semiconductors (also known as amorphous semiconductors), such as amorphous silicon, glass oxide semiconductors, organic semiconductors, such as phthalocyanine, copper phthalocyanine, polyacrylonitrile, etc.

The third-generation semiconductor materials are mainly wide bandgap semiconductor materials represented by silicon carbide (SiC), gallium nitride (GaN), zinc oxide (ZnO), diamond, and aluminum nitride (AlN).

Its application fields cover optoelectronics, display, consumer electronics, aerospace and defense and military industry.

Especially in the field of national defense and military industry, the third generation of semiconductors has extremely prominent application advantages.

For example, Northrop Grumman delivered the AN/TPS-80 Surface/Air Multi-Mission Radar (G/ATOR) system with high-power, high-efficiency GaN antenna technology to the U.S. Marine Corps.

GaN antenna technology reduces costs and improves system sensitivity and reliability, and the radar system is an advanced active phased array multi-mission radar that can perceive and respond to a variety of threats such as helicopters, unmanned systems, rocket artillery, and more in real time and 360°.

Compared with the existing radar, it not only has multi-task capabilities, but also has lower O&M costs.

There is also a GEM-T developed by Raytheon for the U.S. Department of Defense for attack aircraft, tactical ballistic missiles and cruise missiles, which is equipped with a GaN launcher and does not need to be recertified during the missile's 45-year service.

Because of this, from the very beginning, foreign countries have carried out all-round technical control over Huaxia.

However, Huaxia has achieved remarkable results in the research of core equipment, substrates, epitaxial materials and related chips, breaking through the blockade of foreign countries.

Peng Xiaojie nodded first, "What he said is right, but there are still problems." ”

"I am mainly responsible for the national defense and military industry, but in the industrialized private industry, there is still a gap with foreign countries, not to do a good job in production, education and research, the industrial chain has not been paved, and there are still problems in high-end precision manufacturing. ”

"We are also lagging behind when it comes to materials applications for 5G and automotive-related industries. ”

"Qorvo in the U.S. introduces the 56GHZ GaN FEM, a new FEM that enables smaller, more powerful and more efficient mmWave phased systems that can distribute signals to areas with higher bandwidth requirements, minimizing system costs for base station equipment vendors. ”

II-IV of Saxonburg, Pennsylvania and Sumitomo Electric of Japan have entered into a strategic partnership to establish a vertically integrated 75mm wafer fabrication platform to manufacture GaN-on-SiC high-electron mobility transistor devices for 5G wireless networks. ”

"Japan's Sumitomo Electric is currently the company with the largest market share in the world's 5G high-power applications, and it is also the largest supplier of Huawei in 5G low-frequency and high-power applications in China, especially in the power supply of 50V and the output power of more than 300W, with advanced technology and superior performance. ”

ROHM has also launched a new model of automotive-grade SiC MOSFET on the basis of the original product, which has formed the industry's largest AEC-Q101 qualified automotive-grade SiC MOSFET product family, providing high-reliability, high-voltage, low-loss power devices for automotive on-board chargers and DC/DC converters, and promoting the development of electric vehicles in the direction of environmental protection and low consumption. ”

"Fujitsu in Japan, NXP in the Netherlands, STMicroelectronics in Switzerland, Infineon in Germany and other companies have strong commercial advantages in the third generation of semiconductors. ”

Mu Jingchi listened to Peng Xiaojie talk eloquently, although he was engaged in materials, he almost had no knowledge in this area, and he was listening very seriously at this time.

Peng Xiaojie talked about his professional knowledge and the business market, steady and unassuming, and did not have any admiration for foreign countries, and there was a kind of courage in his tone that we can also do.

"At present, the global third-generation semiconductor power electronics industry pattern is led by the United States, followed by Japan and Europe, the United States has an absolute advantage in the global SiC industry, and the GaN field also has a relatively complete industrial chain, and the upstream and downstream of the industrial chain have the corresponding foundation. ”

"Europe has a complete SiC industry chain and great advantages in technology, while Japan has reached the world's leading level in epitaxy, device preparation and application of GaN and SiC substrates. ”

"Of course, we are not bad, the 13th Research Institute and the 55th Research Institute of Huaxia Electric Technology have built a world-class chip design and processing platform, and its technical strength has occupied a leading position in the world in the field of SiC high-power devices, GaN high-efficiency and high-power and GaN millimeter wave chips. ”

"Xidian University and the Institute of Microelectronics of the Chinese Academy of Sciences have formed a complete technical system in terms of epitaxial material growth, device technology and chip design. ”

"And so many more ... ”

Speaking of the latter, Peng Xiaojie is also deeply proud.
