Onsemi and the Czech Ministry of Industry and Trade are halting a planned expansion of silicon carbide production in Rožnov pod Radhoštěm. The project was announced in 2024 as an investment of up to 2 billion dollars.
The company says the decision is linked to changing global demand for silicon carbide and the project's economic viability. Existing production in Rožnov will not be affected, according to onsemi.
The planned project was intended to make the Czech factory capable of handling the entire silicon carbide production chain. The material is used in power electronics, including for electric cars, industrial applications and energy infrastructure.
Onsemi says it will continue investing and hiring in Czechia, at sites in Rožnov and Brno. The company also cites data centres and artificial intelligence as growth areas, but the statement gives no new investment figure or number of jobs.
The expansion was part of European plans to bring chip and power electronics production closer to the European market. The European Commission had previously approved state aid for the project. Scrapping the expansion means the previously announced investment will in any case no longer go ahead; the consequences for the broader European chip strategy remain unclear.
For the Czech government, the news is therefore mixed. The country retains onsemi's existing production and research, but will not receive the additional production chain for which public support had previously been earmarked. For customers, the decision mainly means that an announced expansion of European capacity will not go ahead.
The company has not said that the Rožnov site will close. Nor has it disclosed how many jobs or how much regional economic activity the expansion project would have generated. The essence of the news is therefore the scrapping of future capacity, not an immediate closure or round of redundancies.
As no fully independent second source with additional details was available alongside onsemi's statement, this article remains limited. In particular, the precise financial consequences, the status of any state aid and the impact on European chip supply still need to be confirmed.

Both sides of the figures
▲ Bright spots
- Existing production in Rožnov remains intact, according to onsemi.
- Onsemi says it will continue investing and hiring in Rožnov and Brno.
▼ Concerns
- A planned investment of up to 2 billion dollars will not go ahead.
- The expansion of European silicon carbide capacity is being abandoned, but the precise market impact is unknown.
Critical note
This concerns an announced future investment, not a decline in realised production or turnover. Onsemi gives no figures in the statement on jobs, state aid that may have to be repaid, or the scale of the capacity that will be lost.
Who notices what
- Businesses
- Suppliers and customers are losing an announced expansion, but existing activities remain operational, according to onsemi.
- Workers
- No round of redundancies has been announced; onsemi says it will continue investing and hiring in Czechia.
- Government
- Czechia retains onsemi's existing presence, but still needs to clarify the consequences for previously awarded public support.

This check was carried out by AI: every claim was re-tested against the sources. Even an approved article can contain errors — stay critical.
The central decision has been confirmed by the primary company source, but independent confirmation of the new development is lacking. The text therefore limits claims about jobs, state aid and European consequences.

Editor's note
The cancellation and the consequences for existing activities come from onsemi's statement. The second source confirms the earlier state aid, but not the cancellation; independent confirmation of the new decision is lacking.Sources
