Recently, China's self-developed 4-inch high-purity semi-insulating silicon carbide (SiC) substrate products are available. Experts from the China Electronic Materials Industry Association believe that the results are leading domestically and have reached the international advanced level.
Silicon carbide-based microwave power devices have the characteristics of high frequency, high power, and high temperature resistance and are the core of a new generation of radar systems.
For a long time, high purity semi-insulating silicon carbide substrates of core materials of silicon carbide-based microwave power devices have been difficult to manufacture and process. They have always been a domestic gap. Only a few countries in the world have mastered the technology and have been making technical blockades and products for China. embargo.
It is understood that silicon carbide-based microwave devices as the most ideal microwave device in the world today, its power density is 10 times that of existing microwave devices, will become the standard for next-generation radar technology. The phased-array radars of US military jammers and Aegis destroyers have begun to replace silicon carbide-based microwave devices. The military market will promote the rapid development of silicon carbide-based microwave devices in the next few years.
It can be said that the development of high-purity semi-insulating silicon carbide substrate material is one of the key topics for the breakthrough of the new generation of radar systems in China.
The project developer and the person in charge of Shandong Tianyue Company stated that the successful development of 4-inch high-purity semi-insulating silicon carbide semiconductor material has enabled China to have an autonomous and controllable strategic semiconductor material. It will be a new generation of radar, satellite communications, and communications base stations. The core of the application will be implemented in airborne radar systems, ground radar systems, shipborne radar systems, and missile-borne radar systems.
