Gallium nitride (GaN) and silicon carbide (SiC) are also known as the second-generation semiconductor materials. Gallium nitride has a wide direct band gap, strong atomic bonds, high thermal conductivity, good chemical stability (nearly corroded by any acid) and strong anti-irradiation ability in optoelectronic, high temperature and high power devices. And the application of high frequency microwave devices has broad prospects.

Compared with traditional silicon materials, silicon carbide and gallium nitride are more suitable for high-voltage applications. Among them, silicon carbide is more suitable for high-temperature applications. Gallium nitride is more suitable for high-frequency applications due to the high-speed electron migration.
Domestic research on GaN power devices started late, mainly carried out by some research institutes and universities with the support of relevant national science and technology plans. The focus of power device research is more concentrated in the field of GaN microwave power devices.
It has excellent physical properties with GaN high-power semiconductor devices, and is widely used in the field of microwave integrated circuits, high voltage and high power. Gallium nitride high-power semiconductor devices are also used in inverters, voltage regulators, transformers, wireless charging and other fields. Since the gallium nitride high-power semiconductor device has excellent physical properties such as low conduction loss and high current density, the communication system can significantly reduce power loss and heat dissipation load, and the operation cost can be greatly reduced.
According to the "2016-2021 China GaN Power Electronics Discrete Device Market Development Investment Analysis Report" released by the New World Industrial Research Center, the market demand for domestic GaN power electronic discrete devices in 2016 is only 0.62 billion yuan, nitrogen. The maturity of the related industries of gallium power electronic classification devices is still very low, the domestic supply scale is far below the scale of demand, and the basic products all rely on foreign imports.
Similar to SiC devices, GaN power electronics are another research focus of semiconductor devices. The GaN power electronic discrete device products in the domestic and international markets are gallium nitride diodes and gallium nitride MOSFETs.
Currently, GaN power diodes are dominated by SBD diodes. Among them, the lateral structure utilizes an AlGaN/GaN heterojunction structure to generate current without being doped, which is the main structure of current gallium nitride power electronic devices. However, the lateral conductive structure increases the area and cost of the device, and the forward current density of the device is generally small. Moreover, the lateral structure is generally applied to a voltage environment of 600V or less, and it is urgent to develop a new generation of vertical structure GaN power diodes.
New thinker industry researchers point out that more than 90% of RF GaN devices have SiC substrates because of the very good lattice matching between SiC and GaN, and SiC also has the high thermal conductivity required for GaN. At present, domestic GaN devices mainly have silicon carbide and silicon. MACOM is the only supplier in the world to use GaN on Si technology in the RF field. Other manufacturers use SiC-based GaN.
