Gallium nitride, GaN substrate. GaN has a wide direct bandgap, strong atomic bonds and high thermal conductivity, etc., and it is a strong ability on anti-radiation, not only is the short-wavelength optoelectronic materials, also the replacement materials of high temperature semiconductor device. GaN can be used to make blue and green LED, or violet, ultraviolet light LD, ultraviolet detectors and high-frequency high-power electronic devices.
gallium nitride substrate is renowned for their exceptional properties, including a wide direct bandgap, strong atomic bonds, and high thermal conductivity. These characteristics make GaN an ideal material for a variety of advanced applications. It is particularly effective in resisting radiation, making it suitable for harsh environments. GaN substrates are widely used in the production of blue, green, and violet LEDs, as well as ultraviolet light-emitting diodes (LEDs), ultraviolet detectors, and high-frequency, high-power electronic devices. Additionally, GaN serves as an excellent replacement material for high-temperature semiconductor devices due to its superior thermal performance and robustness. As a leading China gallium nitride substrate supplier, we provide high-quality GaN substrates for a wide range of applications in the optoelectronics and semiconductor industries.

Gallium Nitride Substrate Features
1. Wide Bandgap: GaN has a wide direct bandgap of approximately 3.4 eV, which allows it to operate efficiently at high voltages, temperatures, and frequencies, making it ideal for high-performance applications.
2. High Thermal Conductivity: GaN substrates offer superior heat dissipation, which is crucial for high-power devices. This property ensures better thermal management, reducing the risk of overheating in electronic components.
3. Radiation Resistance: GaN is highly resistant to radiation, which makes it suitable for use in space applications, high-energy physics experiments, and other environments exposed to radiation.
4. Mechanical Strength: GaN has strong atomic bonds, providing excellent mechanical strength and durability. This makes GaN substrates suitable for harsh operational conditions.
5. Optoelectronic Applications: GaN is widely used in the production of blue, green, and violet LEDs, as well as ultraviolet light-emitting diodes (LEDs), offering high luminous efficiency and long lifespan.
Application Scenarios
Semiconductor silicon wafer is the upstream of integrated circuit industry and is an important material for manufacturing integrated circuits.
Semiconductor silicon wafer manufacturing technology is difficult, the downstream application is wide, the market value is high, is the main application field of silicon wafer. Silicon is the starting point of the semiconductor industry chain, through the front and back of the entire chip manufacturing process, without silicon semiconductor industry will be like water without a source. The output and quality of silicon wafers directly restricts the entire semiconductor industry, and the development of many industries such as communications, automobiles, and computers further downstream, and is a key material for manufacturing chips.
Semiconductor products are mainly used in computer, household appliances, digital electronics, electrical, communications, transportation, medical, aerospace and many other fields.
Packaging and Transportation
The packaging should be able to withstand the impact, vibration, stacking and extrusion that may be encountered during transportation, while also it has to easy to load, unload and handle.
We use professional wafer box packaging. The wafer box is protected by a double layer bag, the inside is a PE bag that can be dust-proof, and the outside is a aluminum foil bag that can be isolated from the air. The two-layer bags are vacuum-packed.
We will choose carton models according to different sizes of products. And between the product and the carton filled with shock-proof EPE foam, play a comprehensive protection.
Finally choose air transport to reach the customer's hands. This allows customers in any country and region to receive the product in the fastest time.
We comply with the Material Safety Data Sheet (MSDS) rules to ensure that the products transported are free of harmful substances and will not cause environmental pollution and explosion and other possible hazards.
