Silicon carbide (SiC), once one of the hottest tracks in semiconductors, is going through a new round of reshuffling.
Korea’s The Elec recently reported that LX Semicon is selling more than 60 SiC patents as a package, covering planar-gate and trench-gate MOSFETs, epitaxial wafers, and other technologies. The whole portfolio is expected to sell for less than 1 billion won. This means the South Korean chip company’s roughly five-year SiC venture is about to come to an end.
Similar things are happening at other companies. In July this year, SK Siltron, part of South Korea’s SK Group, announced it would shut down its SiC substrate manufacturing business in Michigan, USA. In China, Hangzhou Taixin Microelectronics was accepted into bankruptcy liquidation by a court in April, and Shenzhen Tengrui Microelectronics has also entered bankruptcy proceedings over debt problems.
Meanwhile, some companies are voluntarily scaling back investment. In July, Roshow Technology announced the termination of two SiC fundraising projects. Microchip’s previously suspended SiC capacity expansion plan in the US also remains on hold in fiscal 2026.
