What is the third generation of China's semiconductor composite material king, anti vibration table gallium nitride or silicon carbide?

Classification of semiconductor wafer materials

Three generations of semiconductor wafer materials have been developed after nearly a century of development.

Digital logic chips, memory chips, etc. semiconductor test anti vibration table

Gan is suitable for high frequency applications, SIC for high pressure applications.

Following is the development trend of various generations of semiconductor materials:

Chinese semiconductor market share is expected to surpass 50% by 2030.

Semiconductors of the second and third generation are introduced

Nitride of gallium

There are three main applications of gallium nitride: LEDs (lighting, displays), RF communication, and high frequency power devices.

Among LED applications, the recently popular miniLED uses gallium nitride, while RF applications mainly involve base station PAs semiconductor test. voltage probe SAN 'an integrated foundry. The power device is mainly used in low-voltage millet chargers, leading to gallium nitride speculation. VCSELs, which are also used by VR//AR, are the core of VR//AR. By 2025, the market for gallium nitride is expected to exceed $10 billion.

Secondly, silicon carbide

In power grids, rail transit, electric vehicles, and charging pile fields, voltage probe silicon carbide has four advantages: high voltage, high frequency, high temperature, long life. In the field of gallium nitride applications, silicon carbide substrates will result in better performance.

It is estimated that the global silicon carbide power device market will reach $1.644 billion in 2023, a compound annual growth rate of 26.6%.

Comparison of the two

Because of its unique properties, silicon carbide is the preferred substrate material for generating silicon carbide epitaxial wafers, which are suitable for high voltage power semiconductor devices, low and medium voltage power semiconductor devices for Gan's epitaxial growth, as well as light-emitting diodes and radio frequency devices.

Electrical vehicles are powered by power semiconductors, display devices are powered by leds, and 5G communications are powered by radio frequency. All three are based on silicon carbide, so I think silicon carbide is the king of semiconductor materials, gallium nitride gentle and elegant, should be called the queen of semiconductor materials.
