Introduction: The Rise of Silicon Carbide Semiconductor Technology
The global semiconductor industry is entering a new stage of development.
Traditional silicon-based semiconductor technology has powered electronics for decades. However, with the rapid growth of electric vehicles, renewable energy systems, fast charging infrastructure, and high-efficiency power electronics, demand for next-generation semiconductor materials is increasing.
Among these advanced materials, silicon carbide (SiC) has become one of the most important wide-bandgap semiconductor materials.
SiC semiconductors offer significant advantages compared with traditional silicon devices:
Higher operating temperature
