  • Fujitsu to Use Copper-Wired Microchips for Future Mainframes
  • January 21, 1999 (TOKYO) — Fujitsu Ltd. said it will use microchips with copper wiring technology for its next-generation mainframe.
    Tatsushi Miyazawa, a member of the board and group executive president of Fujitsu’s computer systems group, said at a press conference Jan. 14 that the technology for transistor interconnections will be used for the subsequent model of its current mainframe GS 8800.

    Fujitsu will start mass-producing the microchips in the fourth quarter of 1999. The marketing date of the new mainframe, however, is not finalized yet, company executives said.

    The company adopts the copper interconnection technology because it can unite high speed and high reliability for microchips, said Noboru Ogi, a member of the board and group president of Fujitsu’s computer technology group.

    A new wafer process called CS 80, which can comply with copper wiring, will be used for the mass production, Nikkei Microdevices has learned. A 0.18-micron design rule also will be used.
