Bosch, a German based engineering company has benefited from CHIPS Act which provided the company with up to $225 million of direct funding towards the development of a semiconductor manufacturing plant in Roseville, the facility is now valued at $1. 9 billion. The company is upgrading its current plant to make state-of-the-art silicon carbide semiconductors for EVs and charging systems and plans to start supplying chips to the market in 2026.
The investment reflects the strategy of the Biden administration to rebuild the domestic semiconductor manufacturing industry. Instead of constructing a new semiconductor plant from the ground, Bosch is refurbishing an old plant that was built in 1984. Bosch retained nearly all 250 employees from TSI Semiconductors and trained them using expertise from the company’s global manufacturing network.
CHIPS Act
Rep. Doris Matsui pointed out the impact of CHIPS Act, the law which she called as a critical tool to build a strong and sustainable semiconductor ecosystem. Paul Thomas, the CEO of Bosch in North America said that the domestic production of silicon carbide semiconductors will help U. S consumers in their journey toward electrification, and this Bosch’s plant in Roseville is right move toward this goals.
Thorsten Scheer, the plant manager pointed out that the company opted to expand an existing wafer fabrication facility rather than construct a new one. He pointed out the talented Roseville workforce as one of the reasons for this approach, saying that the workforce was skilled and committed during the transformation of the site.

In April 2023, Bosch announced its initial investment. Stefan Hartung, the chairman of the board of management, emphasized that the company would build the factory with or without CHIPS Act funding. Bosch originally committed $1.5 billion to the project. The Department of Commerce now reports the total investment has grown to $1.9 billion, according to their recent press release.
