Third-generation semiconductor material gallium nitride may trigger charging revolution

As the feature size of semiconductor processes approaches theoretical limits, the acceleration of Moore’s Law on the semiconductor industry has slowed significantly. In addition to further developing the manufacturing process under Moore’s Law, finding a new generation of semiconductor materials other than silicon (Si) has also become a meaningful direction. In this process, gallium nitride (GaN) has entered people’s field of vision as a high-frequency word in recent years.

GaN is a new type of semiconductor material. It is a compound of nitrogen and gallium. It is a direct bandgap semiconductor and an extensive bandgap semiconductor material. Together with silicon carbide (SiC), it has become a “third-generation semiconductor material,” and the third-generation semiconductor material is becoming the focus of global semiconductor market competition with its superior performance and substantial market prospects.

Compared with GaN, the application research of SiC, which is also a third-generation semiconductor material, started earlier. The main reason why GaN has become more eye-catching in recent years is twofold. First, GaN has shown a reduction in cost. With higher potential, mainstream GaN technology manufacturers are currently developing Si-based GaN devices to replace expensive SiC substrates. Second, because GaN devices are planar devices, they are in line with existing Si semiconductor processes. Strong compatibility, which makes it easier to integrate with other semiconductor devices.

Gallium nitride (GaN) has a higher breakdown voltage (greater than 200V when using GaN), can withstand high input/output mismatch (usually> 15: 1VSWR), has a higher junction temperature, and the mean time between failures is One million hours. It also has high thermal conductivity, high-temperature resistance, radiation resistance, acid and alkali resistance, high strength, and high hardness.

Trunnano is one of the world’s best gallium nitride¬†manufacturers. “We have been supplying gallium nitride¬†steadily, ensuring product quality, and guaranteeing stable supply prices,” said Rachel, sales manager at Luoyang Trunnano.
