SK Siltron has completed the acquisition of DuPont’s Silicon Carbide Wafer (SiC Wafer) unit. The acquisition was decided through a board meeting in September and closed on February 29.
The $450 million acquisition is considered a bold global technology investment to meet the demand from consumers and governments for sustainable energy and environmental solutions. SK Siltron will continue to invest in related fields even after the acquisition, which is expected to increase SiC wafers’ production and create additional jobs in the U.S. The primary site for the business is in Auburn, Mich., about 120 miles north of Detroit.
Demand for power semiconductors is rapidly increasing as automakers are scrambling to enter the electric vehicle market and telecommunication companies are expanding ultra-fast 5G networks. SiC wafers have high hardness, heat resistance and the ability to withstand high voltages. These characteristics make the wafers widely seen as a material to produce power semiconductors for electric vehicles and 5G networks where energy efficiency is important.
