The Literary Life of a Science Leader

Chapter 194 Third Generation Semiconductor Materials (14)

"Oh, what do you say?"

Mu Jingchi said with a smile on his face, "I'm not afraid of your jokes. I initially thought about switching to electronic engineering materials, but I gave up in the end."

"Why did you give up?"

"too difficult."

While talking, Mu Jingchi also felt a little emotional.

Mu Jingchi had indeed thought about the matter of changing directions before, it was not something he said 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.

Breakthroughs in the semiconductor industry involve breakthroughs in key technologies and key materials throughout the industry chain, and there are too many things involved.

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

The entire semiconductor industry in China still involves economic considerations. Even if it imports $3000 billion of chips every year, it is still a commercial matter.

But what Mu Jingchi is doing now is slowly infiltrating into the national defense industry. Compared with the commercial economy, the political ratio of the national defense industry is more important.

"My idea is to help improve our country's military strength. When our military strength becomes stronger, certain foreign restrictions will gradually be lifted. At that time, it may be bought with money."

To truly catch up with the United States in China's semiconductor industry, it will not be possible in a short period of time. What is lacking in this is talent.They are not the kind of talents who come from undergraduates, but the key core talents who are really engaged in research and development and can achieve innovative research and development.

Hearing Mu Jingchi's answer, Shen Fangnan also laughed, "It can't be said that this is not possible, this is also a way, but the road of self-study 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 chose, with systematic help to provide knowledge extraction, this path is really possible.

In the current world structure, only 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 strength, financial strength and semiconductor strength.

In current international relations, unless the United States wants to directly go to war with China, the so-called military power can only provoke the internal affairs of China.

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

Finally, there is semiconductors, which 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.

From this point of view, it is obvious why the United States wants to suppress China's semiconductors.

Because it moved American cheese!
Mu Jingchi used national defense and military materials to intervene in the country's strength, and China's military strength has improved, so there are more things that can radiate and influence.

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

And if Mujingchi can still come up with some black technologies such as nanomaterials, nuclear fusion and even anti-gravity in the medium term, then USD settlement will be used to promote RMB settlement.

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

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

At that time, it was the time when Huaxia left the United States.

The idea is such a general idea. The real relationship between countries and countries must be extremely complicated, but Mu Jingchi's general direction is prepared to go in this way.

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

As for whether it can be realized, it depends on whether the system is powerful and its own ability level.

"Actually, there is no need to be so pessimistic. Our country has actually made considerable progress." Peng Xiaojie's words were still very gentle, and he was still very optimistic about China's development.

"Wuhan Xinxin, a subsidiary of Tsinghua Unigroup, has already achieved a breakthrough in 128-layer stacked 3D NAND FLASH using its proprietary Xtacking architecture. It will be mass-produced in a year or two, and it will be able to seize the international market by then."

"Everything comes little by little."

Peng Xiaojie and Shen Fangnan have known each other for a long time, and they have a good relationship, so it is understandable that Shen Fangnan is worried. After all, he will be beaten if he falls behind.

The first time he was beaten was in the last century, and it caused casualties of life.

And this second attack was caused by the high-tech suppression by the United States in recent years, which caused losses of trillions of dollars.

Not to mention not remembering.

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

Seeing Shen Fangnan's expression, Mu Jingchi didn't continue talking about this aspect, it would only add to his troubles.

"Brother Peng, how is your research?"

Before Peng Xiaojie could speak, Shen Fangnan spoke first, and looked at Peng Xiaojie with resentful eyes, and then said to Mu Jingchi: "His research is better than mine, and the progress is much smoother."

"Now our country is already at the international level in terms of third-generation semiconductors. Although there is still a gap with Japan, Europe and the United States in some aspects, it is not that big. It is still 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 semiconductor materials mainly refer to compound semiconductor materials, such as gallium arsenide (GaAs), indium antimonide (InSb); ternary compound semiconductors, such as GaAsAl, 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, polypropylene Nitrile 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 national defense, etc.

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

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

GaN antenna technology can reduce costs and improve system sensitivity and reliability. The radar system is an advanced active phased array multi-mission radar that can perceive and respond to helicopters, unmanned systems, Multiple threats such as rocket launchers.

Compared with existing radars, it not only has multi-mission capabilities, but also has lower operation and maintenance costs.

There is also a GEM-T developed by Raytheon for the US Department of Defense for attack aircraft, tactical ballistic missiles and cruise missiles.

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 foreign blockades.

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

"I am mainly responsible for the defense and military industry, but there is still a gap between the industrialized private industry and foreign countries. There is no good production, education and research, the industrial chain has not been established, and there are still problems in high-end precision manufacturing."

"We are also behind in the application of materials in 5G and automotive-related industries."

"Qorvo in the United States has launched a 56GHZ GaN FEM. This new type of FEM can achieve a smaller, more powerful, and more efficient millimeter-wave phase control system. It can distribute signals to areas with higher broadband requirements and serve as base stations. equipment suppliers to minimize system costs."

"The II-IV company in Saxonburg, Pennsylvania, USA, and Sumitomo Electric Industries, Japan have launched a strategic cooperation to establish a vertically integrated 75mm wafer manufacturing platform to manufacture GaN-on-SiC high electron mobility for 5G wireless networks. rate transistor devices."

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

"In addition, ROHM Semiconductor has launched a new type of automotive-grade SiC MOSFET based on the original products, and has formed the industry's largest AEC-Q101-compliant automotive-grade SiC MOSFET product series, which is used for automotive on-board chargers and DC/DC conversion. The device provides power devices with high reliability, high withstand voltage and low loss, and promotes the development of electric vehicles in the direction of environmental protection and low consumption."

“Companies such as Fujitsu in Japan, NXP in the Netherlands, STMicroelectronics in Switzerland, and Infineon in Germany all have strong commercial advantages in third-generation semiconductors.”

Mu Jingchi listened to Peng Xiaojie's eloquent talk. Although he was engaged in materials, he had almost no knowledge in this area, so he listened very seriously at this moment.

When Peng Xiaojie talked about his professional knowledge and business market, he was steady and unassuming, and he didn't have any admiration for foreign countries. His tone had a kind of courage that we can also do.

"Currently, the global third-generation semiconductor power electronics industry structure 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. Both the upstream and downstream of the industrial chain have corresponding basis."

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

"Of course we are not bad. Huaxia Electronics' No.13 Research Institute and 55 Research Institute have built world-class chip design and processing platforms. In the fields of SiC high-power devices, GaN high-efficiency and high-power GaN millimeter-wave chips, its technology The strength has already occupied the leading position in the world.”

"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."

"Wait, there are many more..."

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