Bosch has begun sample production of silicon carbide semiconductors on 200mm wafers at its first US semiconductor manufacturing site in Roseville, California, marking a milestone for the German industrial giant’s American expansion.
The Roseville facility, backed by up to $225 million in CHIPS and Science Act grants, represents a total investment of approximately $2 billion. The plant will produce SiC power devices based on Bosch’s second-generation silicon carbide technology, targeting the rapidly growing electric vehicle and industrial power markets.
The Commerce Department said the Roseville fab supports the Biden administration’s goal of onshoring critical semiconductor supply chains. SiC devices are essential for EV traction inverters, charging infrastructure, and industrial power conversion, offering higher efficiency and thermal performance than traditional silicon.
Bosch is one of several European companies establishing US chip manufacturing operations under the CHIPS Act incentive program, which has spurred more than $770 billion in private semiconductor supply chain investments since its passage.
