ST leads in SiC power semiconductor market with 32.6% share

Market researcher TrendForce reports that the SiC power devices industry maintained strong growth in 2023, driven by the application of BEVs. The top five suppliers accounted for approximately 91.9% of total revenue; ST lead the pack with a 32.6% market share while onsemi rose from fourth place in 2022 to second place. TrendForce’s analysis indicates that demand from AI servers and other fields will significantly increase in 2024. However, the noticeable slowdown in the sales growth of BEVs and weakening industrial demand are affecting the SiC supply chain. It is expected that the annual growth rate of industry revenue for SiC power devices will significantly decelerate in 2024 compared to previous years. ST, as a key supplier of automotive SiC MOSFETs, is building a full-process SiC factory in Catania, Italy that is expected to be operational by 2026. Additionally, the 8-inch SiC joint venture factory established by ST and Sanan Optoelectronics in China is anticipated to be up and running by the end of this year. This will enable ST to achieve vertical integration by combining local post-processing production lines and supporting substrate material factories provided by Sanan Optoelectronics. onsemi’s SiC business has progressed rapidly in recent years, mainly due to its automotive EliteSiC series. The company’s SiC wafer factory in Bucheon, South Korea, completed i...
