Since Copper is the topic for today. eocenter.com "Posted: 9:00 p.m., EDT, 8/6/98 Taiwan chip makers investigate copper interconnects By Mark Carroll TAIPEI, Taiwan ? Taiwan Semiconductor Manufacturing Co. Ltd. (TSMC) and United Microelectronics Corp. (UMC) have each started R&D work on the use of copper interconnects for ICs. The Taiwan-based companies expect to apply the technology to their IC manufacturing operatings in September 1999, with mass production of copper-wired ICs slated for the end of that year. The use of copper interconnects will help cut product costs by 20 percent, according to a TSMC executive. "The use of copper instead of aluminum wiring will also make chips better in terms of electrical resistance," he said. "Despite the fact that the yield rate is expected to be low at the beginning, the new technology still has great potential for manufacturers once our skills improve." TSMC and UMC now lag large foreign competitors working on copper-interconnect technology. Motorola Inc. has transferred its copper chip technology eet.com to Advanced Micro Devices Inc. (AMD). The latter will thus be able to develop chips with billion-byte, high-speed transmission capability. AMD said it will market a 1,000-MHz K7 processor with this technology in the year 2000. IBM Corp. introduced copper-related semiconductor manufacturing technology in September 1997. Among other uses, IBM plans to cooperate with Motorola to apply copper-interconnect technology to the production of Power PC CPUs. Chips manufactured with the new technology use copper wiring as an electrical conductor instead of traditional aluminum interconnects. The resultant chips are smaller, faster and more powerful than the current market's most advanced chips. " Milo
