SK Siltron CSS Announces $300 Million Plant Expansion to Support EV Growth
BAY CITY, MI—SK Siltron CSS, a semiconductor wafer manufacturer, recently announced plans to invest $300 million over the next three years to provide manufacturing and R&D capabilities of advanced materials for electric vehicles in a new facility here. The new site will more than double the company's Michigan employee base and complement SK's existing site in nearby Auburn, MI.
SK Siltron manufactures a specialty wafer made of silicon carbide (SiC) that can be used in the semiconductor power components of electric vehicles. SiC wafers are more efficient at handling high powers and conducting heat than normal silicon. When used in EV system components, this characteristic can allow a more efficient transfer of electricity from the battery to the motor, increasing the driving range of an EV by 5 to 10 percent.
