In the process of developing semiconductors and chip manufacturing, many key materials are used. Up to now, the semiconductor industry has developed to the third generation of material technology.
Gallium nitride, graphene, silicon carbide, silicon-based, etc. commonly on the market are mainstream semiconductor materials. The Chinese Academy of Sciences has made meritorious contributions, based on the research results of the Chinese Academy of Sciences, so that the domestic third-generation chip materials have made a breakthrough. What is the specific material? What is the significance of semiconductors in China?
<h1 class="pgc-h-arrow-right" data-track="4" > a breakthrough in domestic third-generation chip materials</h1>
Global development has been exploring the semiconductor field for more than half a century, making different chip products through these materials and applying them in various industries. Some people use air to describe chips, which means that chips are everywhere, as long as they are electronic devices, almost all of them are inseparable from chips.
The process of human exploration of semiconductors has also experienced a total of three eras of semiconductor materials.
According to the different needs and the degree of research and development, the first generation of semiconductor materials mainly include silicon, germanium elements. The second generation of semiconductor materials have compound materials, and today, scientists and researchers have explored a wealth of third-generation semiconductor materials, including gallium nitride, aluminum nitride, zinc oxide, silicon carbide and so on.
Silicon is the most common and commonly used semiconductor material in the world, but due to the limitations of Moore's Law, it is not so easy to use silicon materials to overcome processes below 3nm. And in the fight against high temperatures, high frequencies and breakdown of electric fields and other environments, silicon performance is not ideal.
In contrast, gallium nitride, silicon carbide, will perform better. Making them into chargers and applying them to high-power devices will attract more attention from the industry.
The era of the third generation of semiconductor materials has arrived, and the ubiquitous Gallium nitride charger proves the feasibility and scalability of the third generation of semiconductor materials. In addition to gallium nitride, the domestic third-generation semiconductor chip material silicon carbide has also made a breakthrough and successfully filled the domestic gap.
According to the news from Beijing Daily, with the support of the research results of the Chinese Academy of Sciences, the third-generation semiconductor material silicon carbide single crystal has achieved mass production in Baoding.
Unlike silicon-based chips, the application scenarios of silicon carbide wafers are mainly concentrated in new energy vehicles, 5G communication networks and so on. This material can provide a very good substrate for 5G chips, ensuring the high-speed network transmission brought by 5G chips.
The future trend is moving towards the new energy, 5G field closer, at this time came the good news that silicon carbide wafer materials have made breakthroughs in mass production, it can be said that it is the right time.
With the rapid development of China's 5G network and the vigorous entry of domestic companies into the new energy vehicle market, it is expected to escort many emerging areas in China. With a large number of silicon carbide wafer production capacity, it will be able to occupy the first hand advantage in the future industrial development competition.
<h1 class="pgc-h-arrow-right" data-track="15" > the significance of semiconductors in China</h1>
The development of semiconductor materials from silicon to gallium nitride, silicon carbide and other fields has brought huge market prospects to various industries around the world. Mainly silicon, chips for electronic products such as mobile phones, computers, and tablets are made of silicon.
Such chips are also known as silicon-based chips, but when the silicon base faces physical limit performance, it is unlikely to become the main theme of scientific and technological development in the next few decades.
After a silicon-based chip is limited by physical rules, the number of transistors that can be accommodated is ultimately limited. The limits of Moore's Law are coming, and in this context, the exploration of third-generation semiconductor materials has become inevitable. Who can take the lead in making a breakthrough in the research and development of the third generation of semiconductor chip materials, then in the future development of the industry, you can grasp the important right to speak. Therefore, the mass production of silicon carbide wafers is of great significance to China's semiconductors.
For example, it provides more possibilities for the domestic semiconductor industry. In the era of the third generation of semiconductor materials, it will not be limited to one material, the performance, power and performance of each material are different, and the applicable scenes are completely different.
But these are worth the continuous exploration of Chinese researchers, the premise of scientific and technological breakthroughs is to continue to study, to explore more ways of technological research and development. Finally, China's researchers have found a good way out, based on silicon carbide wafers, to provide more possibilities for the domestic semiconductor industry.

There are many advanced third-generation semiconductor material technology companies in China, and the main business of Hebei Tongguang Crystal Co., Ltd. is the production of silicon carbide single wafers. Dongguan Tianyu Semiconductor Technology Co., Ltd. is also engaged in research and development, production and sales business in the field of silicon carbide.
The layout of these third-generation semiconductor materials industry has been slowly unfolded, not only the third generation, but also in the first generation of mainstream silicon-based chips, Nanda Optoelectronics, Jingrui Shares, Shanghai Xinyang are also involved in the research and development and production of photoresist materials.
With the participation and support of these domestic enterprises, domestic semiconductor materials continue to break the ice, leaving a strong mark in the blank market field. But it is far from enough, the future development of the semiconductor industry will be faster, similar to graphene, silicon carbide, gallium nitride and other materials will be more in-depth research and development.
<h1 class="pgc-h-arrow-right" data-track="25" > summary</h1>
The third generation of domestic semiconductor materials has made a breakthrough, and the research results of the Chinese Academy of Sciences have been successfully transformed into industrial development. China needs more scientific researchers to participate in technology overcoming, material research and development, and provide a steady forward technical and theoretical basis for the development and progress of the domestic semiconductor industry. In the past, our country lost the first mobile phone will be led by others, now is the time to preemptively attack.
