On June 4, according to Nikkei Asia, Renesas Electronics has abandoned the manufacture of silicon carbide (SiC) power semiconductors. The plan to start production at the Takasaki plant in Gunma Prefecture in early 2025 has been shattered, and the relevant production team was disbanded earlier this year.
It is reported that the two main reasons for Renesas' abandonment of silicon carbide power semiconductor manufacturing are declining market demand and fierce competition from Chinese manufacturers.
In addition, Wolfspeed, an upstream wafer manufacturer in Renesas' silicon carbide supply chain, has recently considered filing for bankruptcy reorganization, which has increased the uncertainty of the $2 billion advance payment that Renesas will pay in 2023.
