SiC Market Summary On September 8, 2023

Compared with traditional silicon (Si) semiconductors, SiC semiconductors have a band gap that is three times that of silicon and a breakdown field that is eight times that of silicon. This allows SiC semiconductors to withstand higher temperatures, stronger electric fields and more Strong radiation environment. In addition, SiC semiconductors also have high carrier mobility and excellent resistance to chemical corrosion, making them promising candidates for use in high-temperature, high-pressure, high-frequency and high-radiation environments.

The applications of SiC semiconductors in the electronic field mainly include power devices, sensors, radio frequency devices and logic devices. In the power field, SiC semiconductors are mainly used in high-voltage, high-temperature, and high-power power electronic equipment, such as inverters, motor drives, solar inverters, power supplies, etc. In the energy field, SiC semiconductors are mainly used for the conversion and storage of renewable energy such as wind and solar energy, as well as the charging and driving of electric vehicles.

The manufacturing process of SiC semiconductors mainly includes steps such as growth, slicing, polishing, metallization, and packaging. Among them, growth is a key step in manufacturing SiC semiconductors, which requires the use of high-temperature, high-pressure, high-purity raw materials and complex growth equipment.

Although SiC semiconductors have many advantages, there are also some challenges in manufacturing and application, such as high manufacturing costs, surface passivation, metal impurities, and thermal stability. In the future, with the continuous development of technology, SiC semiconductors will be more widely used and promoted.
