Under the clear traction of application needs such as 5G communications, new energy vehicles, photovoltaic inverter , currently, leading companies in the application field have begun to use third-generation semiconductor technology, which has further boosted industry confidence and firm commitment to
. Investment in the third generation semiconductor technology route. Performance analysis: Compared with the first and second generation semiconductor materials , the third generation semiconductor material has a wider bandgap (2.2eV), higher breakdown electric field, higher thermal conductivity, and more The high electron saturation rate and higher radiation resistance are more suitable for making high-temperature, high-frequency, high-power and radiation-resistant devices. It can be widely used in high-voltage, high-frequency, high-temperature and high-reliability fields, including radio frequency communications, radar , satellite, power management, automotive electronics, industrial power electronics, etc.
Top Industry Research Institute pointed out that compared with the current mainstream silicon wafer (Si), the third-generation semiconductor materials SiC and GaN, in addition to high voltage resistance, are also high-temperature resistant and suitable for high-frequency operation. The advantage not only allows the chip area to be significantly reduced, but also simplifies the design of peripheral circuits to reduce the size of modules, system peripheral components and cooling systems. Due to the low on-resistance and low switching loss characteristics of third-generation semiconductors, energy conversion losses during vehicle operation can also be significantly reduced, both of which are very helpful in improving the endurance of electric vehicles.
