Onsemi Celebrates expansion of US SiC Facility


Hudson, New Hampshire facility will increase its SiC capacity by five times year-over-year

Onsemi has celebrated the inauguration of its SiC facility in Hudson, New Hampshire with a ribbon cutting ceremony. The ceremony came days after President Biden signed the CHIPS and Science Act into law. The Act will strengthen US supply chain resiliency and help avoid disruptions for critical components.

Signifying the importance of this event and manufacturing of semiconductors in the US were the attendance of multiple guests of honour led by US Secretary of Commerce Gina Raimondo. Also present were US Senators Jeanne Shaheen and Maggie Hassan from New Hampshire, Representative Chris Pappas from the 1st congressional district of New Hampshire and Representative Annie Kuster from the 2nd congressional district of New Hampshire as well as other local governmental dignitaries.

The site will increase the company’s SiC boule production capacity 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 SiC manufacturing supply chain, starting with the sourcing of SiC powder and graphite raw material to the delivery of fully packaged SiC devices.

Onsemi says this will allow it to provide customers with the assurance of supply required to meet rapidly growing demand for SiC-based solutions in applications such as electric vehicles (EVs), EV charging, and energy infrastructure. The SiC total addressable market is projected to grow from $2B in 2021 to $6.5B in 2026, at a compound annual growth rate of 33 percent..

“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.”

Onsemi says it is the only large-scale supplier of both SiC and IGBT solutions with end-to-end supply capability. During its second quarter earnings call last week, the company announced $4B 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 SiC revenue in 2022 and exceed $1 billion in revenue in 2023.
