It has high transparency, hardness, and good thermal conductivity, which aids in heat dissipation, though it has poor electrical conductivity, necessitating an additional conductive layer. Sapphire substrates are typically used in GaN (Gallium Nitride)-based LEDs.
2. Silicon:Silicon substrates offer the advantages of low cost and compatibility with existing semiconductor manufacturing processes, making them suitable for mass production. However, silicon’s thermal conductivity and heat dissipation capabilities are inferior to those of sapphire and silicon carbide (SiC). Silicon-based LEDs are suitable for low-power applications but may face thermal limitations in high-power applications.
3. Silicon Carbide (SiC):SiC substrates have excellent thermal conductivity and high hardness, making them suitable for high-power LED applications. The primary advantage of SiC substrates is their thermal expansion coefficient, which closely matches that of GaN, reducing defects caused by thermal stress. However, the high cost of SiC substrates limits their widespread use.
4. Aluminum Nitride (AlN):AlN substrates boast very high thermal conductivity and excellent thermal expansion coefficient matching, making them ideal for high-power and high-frequency applications. AlN substrates can effectively dissipate heat, extending the lifespan of LEDs, but their high cost and complex manufacturing process can be limiting factors.
5. Metal Substrates:Metal substrates, such as aluminum and copper, are known for their excellent thermal conductivity and are commonly used in high-power and high-brightness LED applications. Metal substrates typically include an insulating layer to prevent electrical short circuits. Aluminum-based substrates (IMS) achieve good heat dissipation and electrical insulation through an insulating layer and copper circuits.
6. Glass Substrates:Glass substrates are typically used in low-cost LED applications. They offer high transparency and low manufacturing costs but have lower thermal conductivity, making them unsuitable for high-power LEDs.

Selecting the appropriate substrate material is crucial for optimizing LED performance and lifespan. High-power LEDs require excellent heat dissipation, making silicon carbide, aluminum nitride, and metal substrates the preferred choices. For low-power and cost-sensitive applications, silicon and glass substrates may be more economical. The thermal expansion coefficient matching between different substrate materials also affects the reliability and performance of LED chips.

In conclusion, the choice of LED substrate material needs to balance factors such as thermal conductivity, thermal expansion coefficient, electrical performance, and cost to meet the specific application requirements.
