In 2002 Zarlink sold its foundry in Bromont, Quebec, Canada to Dalsa Corporation, and its wafer fabrication facility in Plymouth, UK to X-FAB Semiconductor Foundries AG.
After the sale of the Roborough site in Plymouth to Xfab, the original Plessey Semiconductors site at Cheney Manor, Swindon continued to operate under the Zarlink Semiconductor name until it was sold to MHS Industries in early 2008.
