🌍✨ Bosch begins silicon carbide sample production at Roseville, its first US chip fab

Why we’re watching: Bosch has begun sample production of silicon carbide (SiC) chips at its plant in Roseville, California, the company’s first semiconductor production site in the US.

The site is being converted from an existing wafer fab, and Bosch is investing up to $2 billion in it, supported in part by federal CHIPS funding. 💚

Bosch announced its intention to buy the assets of the Roseville wafer fab in April 2023 and closed the acquisition that August, keeping the site’s staff on through the transition.
