Development of the Silicon Carbide Supply Chain

The silicon carbide supply chain includes substrates, epitaxy, device design, wafer manufacturing, module packaging and other links, of which the cost of substrates and epitaxy accounts for 70% in total. In 2023, the global market share of two domestic substrate manufacturers, Tianke Heda and Tianyue Advanced, will increase rapidly, and it is expected that in 2024, the gap with the industry leader Wolfspeed will be further narrowed.
