DuPont Electronics & Imaging is selling its compound semiconductor solutions business to SK Siltron, a silicon wafer supplier to the semiconductor market based in South Korea.

The transaction is consistent with DuPont’s strategy of active portfolio management and disciplined capital allocation to further align the company’s portfolio with high return opportunities.

“The DuPont CSS business has state-of-the-art technologies for SiC wafer production to serve the power electronics market, but it is not a strategic priority for the E&I business,” said President of DuPont Electronics & Imaging Jon Kemp. “Given its strategic focus, we believe SK Siltron will be a better owner and that the CSS business will thrive under SK Siltron’s ownership.”

The transaction is expected to close by the end of 2019.
