PRAGUE, June 19 (Reuters) - U.S. chipmaker Onsemi

will invest up to $2 billion to boost its semiconductor output

in the Czech Republic, it said on Wednesday, expanding the

company's European capacity as the European Union seeks

self-sufficiency in critical supplies.

The brownfield project would represent one of the largest

foreign investments in the Czech Republic.

Pending approval of state aid, Onsemi will expand its

operations in the eastern town of Roznov pod Radhostem to house

the full production chain for silicon carbide semiconductors

including final chip modules used in the automotive and

renewables sectors.

The investment follows similar moves by STMicroelectronics

-- also for silicon carbide chips -- in Italy, and by

Intel ( INTC ) and TSMC in Germany.

"The site would produce the company's intelligent power

semiconductors essential for improving energy efficiency of

applications in electric vehicles, renewable energy and AI data

centres," an Onsemi statement said.

Silicon carbide chips are more expensive than standard

silicon ones but are favoured by automakers because they are

energy-efficient, lightweight and tough.

Massive supply chain disruptions during the COVID-19

pandemic and a rise in trade tensions with China have heightened

scrutiny of Europe's reliance on Asia for chip supplies, with

recent disruption to Red Sea shipping adding to concerns.

The head of Onsemi's power solutions division, Simon Keeton,

told Reuters that production from the new investment could start

in 2027 but did not disclose further detail on jobs, production

volumes or expected revenue.

The investment is within the company's capital expenditure

target and follows its announcement last week of about 1,000 job

cuts among its 30,000-strong workforce.

Global semiconductor manufacturing is expected to become a

trillion-dollar industry by 2030, expanding from $600 billion in

2021, consultancy firm McKinsey says.

INCENTIVES

Onsemi did not comment on the size of the incentive package

under negotiation with the Czech government.

"With this investment, the company would contribute to the

strategic positioning of the region within the EU's

semiconductor value chain and demonstrate that all EU countries

can benefit from the European Chips Act," Onsemi said.

The STMicroelectronics plant in Catania will cost 5 billion

euros ($5.4 billion) and receive a direct government grant of

about 2 billion euros.

Germany will contribute up to 5 billion euros to TSMC's $11

billion factory in Dresden, German officials said last year.

Intel ( INTC ), meanwhile, plans to spend 30 billion euros on two

chip plants in Germany, with substantial government subsidies.
