onsemi and Czech Republic agree to conclude SiC expansion project, but reaffirm partnership
Intelligent power and sensing technology firm onsemi of Scottsdale, AZ, USA and the Czech Ministry of Industry and Trade have confirmed that they will not proceed with the planned multi-year brownfield expansion to add end-to-end silicon carbide (SiC) power semiconductor production at onsemi’s Rožnov pod Radhoštěm site (a plan of up to $2bn first announced in June 2024). The decision is specifically tied to the evolving dynamics of the global SiC market and is not a reflection on the Czech Republic’s investment environment, which remains an important part of onsemi's long-term manufacturing and growth strategy.
Existing silicon and SiC manufacturing capabilities at Rožnov are not affected and continue to operate as part of onsemi’s global manufacturing network. The site is expected to benefit from continued demand growth in areas such as auto, industrial, AI data centers and emerging applications, and onsemi anticipates ongoing investment and hiring at both its Rožnov and Brno sites. onsemi says that the Czech Republic remains a strategically important manufacturing and development location for it, and this decision does not alter the company's commitment to its operations, employees or future investment in the region.
“The decision by onsemi not to proceed with the production expansion project in Rožnov reflects the current situation in the global semiconductor market,” says Karel Havlíček, First Deputy Prime Minister and Minister of Industry and Trade. “What is important to us is that the company’s existing production in Rožnov will continue unchanged,” he adds. “We value our long-standing cooperation with onsemi, as well as the fact that the company is developing its R&D activities in the Czech Republic alongside its manufacturing operations. I am pleased that the company is planning further investments in both Rožnov and Brno, which we can build on together.”
