12inch SiC wafer's properties

1. Material Properties of SiC:

• Wide Bandgap: SiC has a wide bandgap (~3.26 eV), allowing it to operate at higher voltages, temperatures, and frequencies compared to traditional silicon (Si).
• High Thermal Conductivity: SiC's thermal conductivity is much higher than silicon (about 3.7 W/cm·K), making it well-suited for high-power applications where heat dissipation is critical.
• High Breakdown Voltage: SiC can handle much higher voltages (up to 10 times higher than silicon), making it ideal for power electronics, such as power transistors and diodes.
• High Electron Mobility: The electron mobility in SiC is higher than in traditional silicon, contributing to faster switching times in electronic devices.

2. Mechanical Properties:

• High Hardness: SiC is very hard (Mohs hardness of 9), which contributes to its wear resistance but also makes it difficult to process and machine.
• Stiffness: It has a high Young's modulus, meaning it is stiffer and more durable compared to silicon, which enhances its robustness in devices.
• Brittleness: SiC is more brittle than silicon, which is important to consider during wafer processing and device manufacturing.

12inch SiC wafer's applications

12-inch SiC wafers are primarily used in high-performance power electronics, including power MOSFETs, diodes, and IGBTs, enabling efficient energy conversion in industries such as electric vehicles, renewable energy, and industrial power systems.
