GaN Substrate on Sapphire, GaN Substrate on Si, GaN Substrate on SiC, GaN Substrate on GaN in the Global 4-inch GaN Substrates Market:
GaN substrates can be fabricated on different materials, each offering unique advantages and challenges. GaN on Sapphire is one of the most common configurations due to the cost-effectiveness and availability of sapphire wafers. Sapphire provides a good lattice match for GaN, which helps in reducing defects during the epitaxial growth process. However, the thermal conductivity of sapphire is relatively low, which can limit the performance of high-power devices. GaN on Silicon (Si) is another popular option, primarily because silicon wafers are inexpensive and widely available. Silicon also offers good thermal conductivity, which is beneficial for heat dissipation in high-power applications. However, the lattice mismatch between GaN and silicon can introduce defects, which may affect the performance and reliability of the devices. GaN on Silicon Carbide (SiC) is considered one of the best configurations for high-power and high-frequency applications. SiC has excellent thermal conductivity and a close lattice match with GaN, which minimizes defects and enhances device performance. However, SiC wafers are expensive, which can increase the overall cost of the GaN devices. GaN on GaN substrates, where GaN is grown on a native GaN substrate, offer the best performance in terms of thermal conductivity, lattice match, and overall device efficiency. This configuration virtually eliminates the issues related to lattice mismatch and thermal management, making it ideal for the most demanding applications. However, the high cost of native GaN substrates remains a significant barrier to widespread adoption. Each of these configurations has its own set of trade-offs, and the choice of substrate often depends on the specific requirements of the application, such as cost, performance, and thermal management.
