onsemi has expanded the silicon carbide (SiC) plant in Hudson, New Hampshire it acquired from GT Advanced Technologies.

The site will increase the production of SiC boules by five times year-over-year and almost quadruple the number of its employees in Hudson by the end of 2022. The expansion gives onsemi full control of its silicon carbide manufacturing supply chain, starting with the sourcing of silicon carbide powder and graphite raw material to the delivery of fully packaged SiC devices from other fabs and assembly plants.

onsemi is a major large-scale supplier of both SiC and insulated-gate bipolar transistors (IGBT) solutions with end-to-end supply capability. It says it has $4bn of committed SiC revenue for the next three years through long-term supply agreements with a broad base of customers. It will triple last year’s silicon carbide revenue in 2022 and exceed $1 billion in revenue in 2023.

Signifying the importance of this event and manufacturing of semiconductors in the US following the signing of the CHIPS Act last week, the opening was attended by US Secretary of Commerce Gina Raimondo and the two senators from New Hampshire.

The SiC total addressable market is projected to grow from $2bn in 2021 to $6.5bn in 2026, at a compound annual growth rate of 33%.

“In addition to market-leading efficiency of our products, our end-to-end vertically integrated solution in a supply-constrained environment is a compelling and differentiated competitive advantage,” said Simon Keeton, executive vice president and general manager Power Solutions Group at onsemi. “We have already expanded to a second building as we increased our substrate capacity and plan to continue ramping, allowing us to source our own cutting-edge SiC wafers for customer products.”
