SAN FRANCISCO—Fujitsu Semiconductor Ltd. will close one semiconductor test and assembly facility in Japan and transfer ownership of two others to J-Devices Corp., a test and assembly specialist, under the terms of an agreement signed last week.
Fujitsu (Yokohama, Japan) said the move is part of its continuing migration to a "fab-lite" strategy first announced in 2009. The two companies aim to build a long-term, mutually beneficial strategic partnership, Fujitsu said.
J-Devices (Usuki, Japan), formerly known as Nakaya Micro Devices, is a joint venture that is owned in part by Amkor Technology Inc. and Toshiba Corp.
The transaction completed by the end of this year. All employees of the two plants—located in the Miyagi and Aizu prefectures—are expected to be transferred to J-Devices, Fujitsu said. The company said it plans a staged transfer of the equipment from its test and assembly facility in the Kyushu region to an existing J-Devices facility in the same region.
