The rapid development of automotive electronics, 5G technology, new energy vehicles, rail transit and other industries has increased the demand for high-temperature, high-power, high-voltage, high-frequency devices in electronic technology, so the third-generation semiconductor came into being. The third generation semiconductors mainly include silicon carbide (SiC), aluminum nitride (AlN), gallium nitride (GaN), diamond, and zinc oxide (ZnO). Among them, SiC and GaN are more mature.

The United States, Japan, Europe and other countries have carried out active strategic deployment. Infineon, Roma, Texas Instruments, STMicroelectronics and other international manufacturers have also begun to act on the third generation of semiconductors, making the third generation Semiconductor materials have attracted worldwide attention and become the focus of semiconductor technology research and industry competition. In addition, TSMC, the world’s advanced, stable, X-Fab, Han Lei and Huanyu and other Taiwanese foundries participated in the development of the third-generation semiconductor, and gradually pushed the third-generation semiconductor to the C position.

As we all know, China is now vigorously developing the integrated circuit industry. The third-generation semiconductors have also received important attention as important materials and components for next-generation electronic products.
