A GaAs epitaxial wafer is a single crystal thin layer material epitaxially grown on a GaAs substrate.

As a second-generation semiconductor, GaAs is expensive and is known as the semiconductor aristocracy. GaAs is internationally recognized as the most mature compound semiconductor material after silicon. It has superior characteristics such as high frequency, high electron mobility, high output power, low noise and good linearity. It is one of the most important supporting materials for the optoelectronics and microelectronics industries. The second generation of semiconductors represented by gallium arsenide is widely used in the manufacture of high-frequency, high-speed, high-power, low-noise, high-temperature resistant, and radiation-resistant integrated circuits. It has developed into a key technology for modern electronic information products and information highways. The 5G chip market is very good and the products are in short supply. Gallium arsenide (GaAs) is an indispensable component for optoelectronics and mobile phone network high-frequency communications. In recent years, with the surge in the application of the Internet of Things (loT), Internet of Vehicles, and Al (artificial intelligence), countries have accelerated the deployment of 5G infrastructure. In addition, the introduction of facial recognition function by Apple iPhoneX has driven a surge in demand for gallium arsenide VCSEL and high-end communication components.

The market for gallium arsenide epitaxial wafers is concentrated. In the global market, the top companies are all large companies. IQE is the leader so far, with nearly 49% of the revenue market share. From a regional perspective, GaAs industry chain suppliers are mainly concentrated in Europe, the United States, Japan, and Taiwan. The main suppliers in the industry include IQE, New Optoelectronics, IntelliEPI, Sumitomo Chemical and Lianya Optoelectronics. GaAs epitaxial wafer production capacity is highly concentrated and the industry barriers are high.

GaAs epitaxial wafers can be classified according to their manufacturing methods. The MOCVD method accounts for 70% of the global revenue market share.

GaAs semiconductors have the characteristics of high operating frequency, electron migration rate, resistance to natural radiation and low power consumption, and are widely used in the field of microwave communications. On the one hand, as smartphones enter the 5G era, the demand for multi-mode and multi-frequency GaAs microwave power devices will increase significantly compared to the 4G era. VCSEL will become one of the important growth points of GaAs in the future.
