Onsemi Completes Expansion of Silicon Carbide Plant

Power and sensing technologies supplier Onsemi held a ribbon cutting event on August 11 to mark the completion of an expansion project at its silicon carbide (SiC) plant in Hudson, NH. A company release said the project will increase the firm’s production capacity for SiC boule by five times year-over-year by the end of 2022.

“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.”

US Secretary of Commerce Gina Riamondo, US Senators Jeanne Shaheen and Maggie Hassan, and several other officials attended the ceremony.

The expansion of the Hudson location will aid the company in meeting growing demand for SiC-based solutions used in electric vehicles (EVs), EV charging, and energy infrastructure. Onsemi is a large-scale supplier of both SiC and insulated-gate bipolar transistors (IGBT) solutions.

Following the capacity expansion project, the company expects to generate $1 billion in revenue in 2023 from silicon carbide products.
