- Production expansion across Germany and the United States supports large-scale supply growth.
Robert Bosch GmbH has introduced its third-generation silicon carbide (SiC) chips, marking a significant advancement in power semiconductor technology for electric vehicles. The Bosch SiC chips are designed to enhance overall vehicle efficiency while extending driving range. By delivering approximately 20% higher performance compared to earlier versions, these chips contribute directly to improved energy conversion within EV powertrains. Their reduced size also allows for more compact and efficient integration into drive electronics systems.
Performance Advancements Driving EV Efficiency
The newly developed SiC chips focus on improving power density and minimizing energy losses within electric drivetrains. Their compact architecture enables better thermal management and optimized system-level performance. As a result, automakers can achieve higher efficiency levels without increasing system complexity. This advancement supports the broader industry goal of extending EV range while maintaining reliability and performance under demanding operating conditions.
Production Scale and Global Expansion Strategy
Since beginning mass production of its first-generation SiC chips in 2021, Bosch has supplied more than 60 million units globally. The company is now intensifying its efforts to establish itself as a leading supplier in the electromobility semiconductor space. To meet rising demand, Bosch has significantly expanded its research, development, and clean-room manufacturing capabilities. It is targeting mid-nine-figure production volumes in the medium term, reflecting strong confidence in market growth.
Manufacturing Footprint Across Key Regions
Bosch operates a semiconductor wafer fabrication facility in Reutlingen, Germany, where third-generation SiC chips are produced using advanced 200-millimeter wafer technology. In parallel, the company is preparing its facility in Roseville, United States, to begin SiC chip manufacturing. This site is expected to deliver its first samples in 2026, further strengthening Bosch’s global supply network and ensuring scalability for future demand.
