Aluminum nitride (AlN) is a fourth-generation semiconductor material with a bandgap of up to 6.2eV, which makes AlN an ideal material for preparing optoelectronic devices such as UV LEDs. Its high performance is mainly reflected in high breakdown field strength, high saturated electron drift rate, high thermal stability, high thermal conductivity, and radiation resistance.

Aluminum nitride (AlN) single crystal substrate is a wide bandgap semiconductor material with special properties, and its preparation method is mainly the PVT method. At present, due to some problems of aluminum nitride single crystal itself, such as cost and size, the commercialization process is limited. However, its high thermal conductivity, thermal stability and other properties make aluminum nitride substrate have broad application prospects in semiconductor devices, lasers and other fields.

At present, the core companies of aluminum nitride single crystal substrates in the world are mainly Ultratrend Technologie, HexaTech, Crystal IS (Asahi Kasei) and Nitride Crystals. Among them, the Chinese company Ultratrend Technologie released a 2-inch aluminum nitride single crystal substrate in 2021 and prepared a 3-inch substrate sample at the end of 2022. The aluminum nitride single crystal substrate market is highly concentrated. Due to factors such as cost, demand, and technology, the market size of aluminum nitride single crystal substrates is not very large, and there are very few companies that can develop large sizes (4 inches), and the products are mainly concentrated in 2 inches.
