In September last year, SK Siltron, one of the world's top five wafer manufacturers, decided to acquire DuPont's wafer unit for $450 million. Today, SK Siltron said it had completed the acquisition on the 29th of last month.

SK Siltron expects the SiC wafer market to grow at a rate of more than 10% each year. Maximizing the synergy between DuPont's R&D and production capabilities and SK Siltron's major businesses will ensure new growth momentum for SK Siltron.

In fact, South Korea has a high dependence on Japan in terms of wafer materials. Once Japan makes new export restrictions, wafers are likely to be classified as sanctioned products. A spokesperson for SK Siltron said: "This acquisition aims to improve our global competitiveness while responding to the government's policy for material technology autonomy."
