Bosch has signed a binding agreement with the U.S. Department of Commerce for up to $225 million in subsidies under the CHIPS and Science Act, funding the conversion of its Roseville, California, facility into a silicon carbide semiconductor plant. The German automotive supplier is investing up to $2 billion in the site overall.
The federal support underpins Bosch's push to establish domestic U.S. production of energy-efficient SiC chips, which are critical to electric vehicles and renewable-energy systems. Sample production has already begun at the Roseville plant, with full-scale commercial manufacturing expected to start later this year — roughly three years after Bosch acquired the facility from TSI Semiconductors in August 2023.
The investment bolsters Bosch's position in a fast-growing chip segment. The company has shipped more than 60 million SiC chips globally since 2021.
