Roseville residents will see a longtime manufacturing site shift into high-tech semiconductor production after Bosch announced a federal award to support a major upgrade of its local facility.
The company said it reached a definitive agreement with the U.S. Department of Commerce's CHIPS Program Office for up to $225 million in direct funding to help support Bosch's planned $2 billion transformation of its Roseville site. Bosch also reported that sample production of silicon carbide (SiC) semiconductors is already underway at the facility and that the company intends to begin commercial production on 200-millimeter wafers in 2026.

What changes for Roseville
The Roseville plant, which Bosch notes has more than 40 years of semiconductor manufacturing experience, will shift toward producing and testing SiC devices — components increasingly used in electric vehicles and power electronics. The CHIPS Program Office funding is intended to accelerate construction, equipment installation and process upgrades at the site.
Local impacts likely to follow include increased construction activity, the arrival of advanced manufacturing equipment and expanded technical staffing needs. Bosch has not released a local hiring count in the announcement; however, the scale of the investment and move to commercial production in 2026 suggest a multi-year ramp-up that will touch contractors, suppliers and the regional labor market.
- Federal support: up to $225 million from the Department of Commerce CHIPS Program Office.
- Corporate investment: up to $2 billion to convert and equip the Roseville facility.
- Production timeline: sample production underway now, first commercial 200mm SiC chips planned in 2026.
Broader context
The award is part of a national push to expand domestic semiconductor manufacturing and reduce reliance on overseas supply chains. Bosch, which the company says is a leading global automotive supplier, will apply its SiC technology at the Roseville site to support markets that include electric vehicles and industrial power systems.

City and county officials were not quoted in Bosch's release. The company described the move as a "profound evolution" of the Roseville site into a facility that produces and tests SiC semiconductors using modern processes and equipment. For residents, the development could mean new employment opportunities, more contractor work and changes to local supply chains as the plant ramps up toward full production.
News Block will continue to follow local permitting, hiring and community impacts as the project advances toward commercial output.
