Epitaxial wafer refers to a product formed by growing a layer of new single crystal on a single crystal substrate. Epitaxial wafer determines about 70% of the performance of the device and is an important raw material for semiconductor chips. As a semiconductor raw material, epitaxial wafer is located at the upstream of the semiconductor industry chain and is a supporting industry for the semiconductor manufacturing industry. Epitaxial wafer manufacturers use CVD (Chemical Vapor Deposition) equipment, MBE (Molecular Beam Epitaxy) equipment, HVPE equipment, etc. to perform crystal epitaxial growth on substrate materials to make epitaxial wafers. Epitaxial wafers are then made into wafers through manufacturing links such as lithography, thin film deposition, and etching. Wafers are further cut into bare chips, and bare chips are finally made into chips through packaging links such as fixing on the substrate, adding a protective shell, connecting the chip circuit pins with the external substrate with wires, and testing links such as circuit testing and performance testing. The above chip production links need to interact with the chip design link to ensure that the final chip meets the chip design requirements.

Based on the performance of gallium nitride, gallium nitride epitaxial wafers are mainly suitable for applications under high power, high frequency, medium and low voltage, which are specifically reflected in: 1) High bandgap width: The high bandgap width improves the voltage resistance level of gallium nitride devices and can output higher power than gallium arsenide devices, which is particularly suitable for 5G communication base stations, military radars and other fields; 2) High conversion efficiency:

The on-resistance of gallium nitride switching power electronic devices is 3 orders of magnitude lower than that of silicon devices, which can significantly reduce switching conduction losses; 3) High thermal conductivity: The high thermal conductivity of gallium nitride gives it excellent heat dissipation performance, which is suitable for the production of devices in high power, high temperature and other fields; 4) Breakdown electric field strength: Although the breakdown electric field strength of gallium nitride is close to that of silicon nitride, it is affected by factors such as semiconductor technology and material lattice mismatch.

The voltage tolerance of gallium nitride devices is usually around 1000V, and the safe operating voltage is usually below 650V.
GaN devices can conduct electrons more efficiently than silicon devices and can withstand higher electric fields. It exceeds the performance of silicon devices in terms of speed, temperature and power, and has gradually replaced silicon-based devices in power conversion and RF applications. Due to the higher efficiency, significantly reduced size, lighter weight and better heat dissipation performance of GaN-based systems, it has begun to replace traditional silicon devices on the market and has enabled new applications such as lidar and RF envelope tracking.

With the continuous update and generation of LED chip technology and process, the luminous efficiency, technical performance, product quality and cost-effectiveness of LED lighting products have been greatly improved; coupled with the increasing number of related enterprises and investments in the industrial chain, the production and manufacturing technology of LED light source manufacturing and supporting industries has been continuously upgraded, and the cost-effectiveness of large-scale production of terminal products has been further improved. At present, LED lighting products have become the mainstream application in application fields such as home lighting, outdoor lighting, industrial lighting, commercial lighting, landscape lighting, backlight display, etc. The market penetration rate of LED lighting products replacing traditional lighting products continues to increase, and market demand continues to grow. There are still many difficulties in the development and industrialization of Micro-LED display technology. At the same time, Micro-LED epitaxy has stricter requirements on defects and uniformity than traditional LEDs. In the future, the penetration of gallium nitride technology in the LED optoelectronic field will gradually expand.
