It is one of the most important supporting materials in optoelectronic and microelectronic industry.
The second generation semiconductor represented by gallium arsenide is widely used in the manufacturing of integrated circuits such as high frequency, high speed, high power, low noise, high temperature resistance and radiation resistance. It has developed into a key technology of modern "electronic information products" and "information highway". 5g chip market is very good, and products are in short supply. Gallium arsenide (GaAs) is an indispensable component for high-frequency communication of Optoelectronics and mobile Netcom. In recent years, with the surge in the application of Internet of things (IOT), Internet of vehicles and AI (Artificial Intelligence), countries have accelerated the construction of 5g infrastructure. In addition, Apple iPhone X has introduced face recognition function, which has greatly increased the demand for gallium arsenide VCSEL and high-order communication components. Facing the great business opportunities of gallium arsenide industry, gallium arsenide and optoelectronic plants at home and abroad have made every effort to seize them.
GaAs can process photoelectric data on one chip at the same time, so it is widely used in many optoelectronic fields, such as remote control, mobile phone, DVD computer peripherals, lighting and so on. In addition, because its electron mobility is 6 times higher than that of silicon, GaAs has become a necessity for ultra-high speed and ultra-high frequency devices and integrated circuits. It is also widely used in the military field. It is an important material for laser guided missiles. It once showed great power in the Gulf War and won the reputation of "gallium arsenide defeats steel".The price of GaAs single crystal wafer is about 20 to 30 times that of silicon single crystal wafer of the same size. Despite the high price, the annual sales of GaAs semiconductors in the world are still more than US $1 billion
