Diodes to integrate U.S. operational 200mm facility and workforce into global manufacturing operations

Seattle, Wash., June 3rd, 2022 – ATREG, Inc., which specializes in helping advanced technology companies divest and acquire infrastructure-rich manufacturing assets (semiconductor fabs and cleanrooms) worldwide, announced today that the acquisition of onsemi’s operational 200mm manufacturing fab located in South Portland, Maine, USA (SPFAB) by Diodes Incorporated has officially closed. This fab divestment is part of onsemi’s fab-liter manufacturing strategy aimed at sustainable financial performance through gross margins expansion. By integrating this U.S.-based facility into its existing wafer fabrication operations in Asia and Europe, Diodes will add 200mm capacity for analog products and be able to accelerate its growth initiatives in the automotive and industrial markets.

“Demand for 200mm brownfield fab assets is at an all-time high and semiconductor manufacturers are leaving no stone unturned to maintain and increase their wafer production capacity,” adds Stephen Rothrock, founder, president, and CEO of ATREG. “With this disposition, onsemi can now transition production from the South Portland fab to other manufacturing sites while Diodes benefits from fully operational facilities and needed engineering talent in the context of a global workforce shortage.”
