China Silicon Carbide Industry Report, 2019-2025

Silicon carbide (SiC) is the most mature and the most widely used among third-generation wide bandgap semiconductor materials. Over the past two years, global SiC market capacity, however, hovered around 3 million tons due to producers’ unwillingness to expand production, a result of high technical barriers (unstable quality of the raw material crystal column).

Wide bandgap semiconductor devices based on silicon …

They are capable of faster switching speeds, lower losses and higher blocking voltages, which are superior to those of standard silicon-based devices. Huge environmental benefits are also involved. “If the world’s silicon power devices used within this range with were replaced by 3C-SiC devices, a reduction of 1.2×10^10 kilowatts per year could be obtained,” Fisicaro said.
