Product Description of SiC Wafer:

The rapid development of first-generation and second-generation semiconductor materials represented by silicon (Si) and gallium arsenide (GaAs) has propelled the swift advancement of microelectronics and optoelectronics technologies. However, due to limitations in material performance, devices made from these semiconductor materials mostly operate in environments below 200°C, failing to meet the requirements of modern electronics for high-temperature, high-frequency, high-voltage, and radiation-resistant devices.

Therefore, the emergence of next-generation semiconductor materials has become imperative, with silicon carbide wafers emerging as the representative of third-generation semiconductor materials. Silicon carbide wafer exhibits outstanding characteristics such as a wide bandgap (approximately three times that of Si), high thermal conductivity, high electron saturation drift velocity (2.5 times that of Si), and high breakdown electric field (10 times that of Si or 5 times that of GaAs).

The character of SiC Wafer:

1. Wide Bandgap:

Silicon carbide wafers have a wide bandgap, typically ranging from 2.3 to 3.3 electron volts, higher than that of silicon. This wide bandgap enables silicon carbide wafer devices to operate stably in high-temperature and high-power applications and exhibit high electron mobility.
2. High Thermal Conductivity:

The thermal conductivity of silicon carbide wafers is approximately three times that of silicon, reaching up to 480 W/mK. This high thermal conductivity allows silicon carbide. wafer devices to dissipate heat quickly, making them suitable for the thermal management requirements of high-frequency electronic devices.
3. High Breakdown Electric Field:

Silicon carbide wafers have a high breakdown electric field, significantly higher than that of silicon. This means that under the same electric field conditions, silicon carbide wafers can withstand higher voltages, contributing to increased power density in electronic devices.
4. Low Leakage Current:

Due to the structural characteristics of silicon carbide wafers, they exhibit very low leakage currents, making them suitable for applications in high-temperature environments where strict requirements for leakage current exist.
