SK Siltron CSS, a semiconductor wafer manufacturer, announced plans to invest $300 million and create up to 150 high-paying, skilled jobs in Bay County, MI, over the next three years to provide manufacturing and R&D capabilities of advanced materials for electric vehicles.

The expansion will more than double the company's Michigan employee base and add a new site in Bay City, MI, to join its existing site in nearby Auburn, MI.


SK Siltron CSS 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%. 


"The rise in popularity of electric vehicles has the auto industry searching for new innovative technologies to meet customer demand," said Jianwei Dong, CEO at SK Siltron CSS. "Our Michigan expansion will allow us to manufacture advanced materials that can enhance the performance of an EV and support the growth of a more sustainable automotive future."


The SK Siltron CSS expansion, pending state and local approvals, is part of a new domestic supply chain forming to provide the components required to support new environmentally friendly vehicles.


"As we build toward a more sustainable future, it is important that we create new, robust supply chains in the U.S. to support our corporations and the end consumer," said U.S. Secretary of Commerce Gina M. Raimondo. "The automotive industry has a tremendous opportunity with the rise of the electric vehicle, and we're excited to see companies like SK Siltron CSS expanding to help support the transition to a green future."

The company will work closely with state and local partners to recruit and train potential employees. Of the new employees, 70% will be skilled workers while 30% will be professional engineers.
