Domestic substrate manufacturers are rising, challenging Wolfspeed's market position

In recent years, Chinese substrate manufacturers have made significant technological progress, posing a strong challenge to Wolfspeed's global market position. From 2021 to 2023, Wolfspeed's silicon carbide substrate market share will drop from 62% to around 35%. At the same time, Chinese substrate manufacturers such as Tianyue Advanced and Tianke Heda have been included in the supply chains of internationally renowned companies, and their cooperation in the 8-inch market does not lag behind leading manufacturers such as Wolfspeed.
