Bosch announced a definitive agreement with the U.S. Department of Commerce to receive up to $225 million in direct funding from the CHIPS for America program, as part of a $2 billion investment to transform its Roseville, California plant into a facility specialized in manufacturing silicon carbide semiconductors (SiC).
The company reported that the plant, with nearly four decades of experience in semiconductor production, has already begun sample manufacturing and expects to start commercial production on 200 mm wafers during 2026.
The initiative is part of Bosch’s strategy to strengthen domestic manufacturing of power electronic devices and respond to growing demand from sectors such as electric mobility, energy infrastructure, industrial automation, and data centers.
Bosch: Silicon Carbide Redefines Power Electronics
The most relevant aspect of the project is not solely the industrial expansion, but the technology that will be manufactured in Roseville.
Silicon carbide (SiC) belongs to the family of Wide Bandgap Semiconductors, materials that surpass conventional silicon in high-power applications.
From a physical standpoint, Bosch’s SiC withstands significantly higher electric fields, operates at elevated temperatures, and exhibits lower losses during electronic switching. These properties enable the development of more compact power converters with higher efficiency and reduced cooling requirements.
In electric vehicles, these characteristics translate into reduced energy losses during current conversion, increasing range and decreasing charging times. In industrial applications, they enable smaller, lighter equipment with higher power density.
SiC Chips Drive Electrification Across Multiple Industries
Although electric mobility currently constitutes the primary market for SiC devices, their adoption is rapidly expanding toward other strategic infrastructures.
Photovoltaic inverters, energy storage systems (BESS), fast chargers for electric vehicles, converters used in smart grids, and data center power supply systems are among the equipment requiring power electronics capable of operating with high efficiency.
Silicon carbide devices enable improved efficiency in electrical conversion systems, reducing heat generation and load on cooling systems.
This convergence of electrification, digitalization, and artificial intelligence is driving a market where advanced semiconductor materials are acquiring an increasingly strategic role.
Domestic Manufacturing Seeks to Strengthen Supply Chain Resilience
The transformation of Roseville also responds to an industrial strategy aimed at strengthening semiconductor manufacturing capacity within the United States.
The disruptions recorded in global supply chains in recent years highlighted the dependence of Western manufacturers on production concentrated in Asia for critical components.
Through the CHIPS program, the U.S. government seeks to incentivize the localization of industrial capabilities associated with technologies considered strategic for sectors such as automotive, energy, defense, and telecommunications.
In this context, Bosch will leverage the plant’s existing infrastructure, retain specialized personnel, and expand technical training of its workforce to accelerate the commissioning of new production lines.
