SK Siltron secures DOE loan to expand production of SiC wafers for EVs

By Michelle Froese | March 28, 2024

The US Department of Energy’s (DOE) Loan Programs Office (LPO) announced a conditional commitment to SK Siltron CSS, LLC for a $544 million loan to expand American manufacturing of high-quality silicon-carbide (SiC) wafers for electric vehicle (EV) power electronics.

SiC semiconductors are designed for high-voltage use and are critical components of EV drivetrains, including inverters, and electrical distribution systems like onboard chargers and dc-to-dc converters. The project is expected to create up to 200 construction jobs in the build-out phase and up to 200 skilled, good-paying operations jobs at full production at the SK Siltron facility located in Bay City, Michigan.

The facility is projected to be among the top five manufacturers of SiC wafers globally, boosting America’s manufacturing competitiveness and expanding our global leadership in the clean energy technologies of the future. The project will also help build a more resilient semiconductor supply chain and grow a diverse domestic semiconductor workforce to give American industry and workers across the nation a competitive edge on the world stage.

SiC semiconductors allow for higher efficiency and higher voltage, which can mean faster charging times and up to 10% longer range when compared with traditional silicon semiconductors. However, semiconductors made from high-quality SiC wafers are required to maximize these performance improvements. High-quality wafers are currently under-supplied, and demand is expected to rise with EV sales, which saw unprecedented progress in 2023.

Since President Biden took office, EV sales have more than quadrupled, with more than four and a half million EVs on the road. EVs contain about twice as many semiconductors as internal combustion engine vehicles. The adoption of high-voltage architectures will drive demand for SiC semiconductors globally as the EV market is expected to grow significantly in the years to come. The project will help meet the growing market demand for EVs and establish a secure technology supply chain, which will create high-quality jobs and deliver new economic opportunities to surrounding communities.

If finalized, the LPO-financed project will help SK Siltron CSS leverage its two existing Michigan manufacturing plants to address this market gap. Historically, much of the research and development for the manufacturing process has occurred at the company’s facility in Auburn, Michigan. The expanded Bay City plant will use technology developed in Auburn to create the high-quality wafers needed to realize President Biden’s EV goals.

The company will partner with Delta College, less than a mile from the project site, through the Michigan New Jobs Training Program to train local workers for success in SiC wafer manufacturing. In addition, LPO works with all borrowers to create quality jobs during construction, operations, and throughout the life of the loan and works to ensure borrowers develop and ultimately implement a strong Community Benefits Plan.

While this conditional commitment indicates the Department’s intent to finance the project, the company must satisfy certain technical, legal, environmental, and financial conditions before the Department enters into definitive financing documents and funds the loan.
