TOKYO Hitachi Ltd. today said that it will assume management control of Hitachi Nippon Steel Semiconductor Singapore Pte. Ltd., a joint-venture DRAM fab in Singapore, because Nippon Steel Corp., one of the venture's partners, has decided to convert its 35 percent equity interest to nonvoting stock.
Nippon Steel's directors will leave the venture's board. Hitachi will appoint four directors to the board, and one will be selected by the Singapore Economic Development Board, the fab's other partner. Last year, Nippon Steel had sold a DRAM fab it owned in Japan to United Microelectronics Corp. (Hsinchu, Taiwan).
A Hitachi spokesman said it was necessary to change the joint venture's management structure in order to become more responsive to the fast-changing DRAM market. Hitachi continues to view the Singapore fab as a key site for the production of advanced DRAMs. The fab can process 20,000 eight-inch wafers per month.
