| TSMC, UMC Engage in Copper Chip R&D;
August 6, 1998 (TAIPEI) -- Taiwan Semiconductor Manufacturing Co. Ltd.
(TSMC) and United Microelectronics Corp. (UMC) both started research
and development of copper chips.
|They aim to keep up with major foreign competitors, which have been continually
upgrading their semiconductor manufacturing technology.
The two Taiwan-based companies are expected to begin applying their new
technology in manufacturing in September 1999, before mass production
slated for the end of that year.
When manufacturing chips with the new technology, copper wiring is used
as an electrical conductor instead of the traditional aluminum device
interconnects. The chips produced are smaller, faster and more powerful
than the most advanced chips available on the market today.
Motorola Inc. has transferred its copper chip technology to Advanced
Micro Devices Inc. (AMD), and the latter is thus able to develop chips
with billion-byte, high-speed transmission. AMD has announced that it
will introduce to the market a 1,000MHz, K7 processor with the technology
in the year 2000.
International Business Machines Corp. (IBM) also introduced a copper-related
semiconductor manufacturing technology in September 1997. That company,
too, plans to cooperate with Motorola to apply the technology to the
A TSMC executive said the use of copper will help cut product cost by
20 percent, and will make chips better in terms of electrical resistance.
Despite the fact that the yield rate is low at the beginning, the new
technology still has great potential for manufacturers once their skills
improve, the executive added.
TSMC and UMC are likely to begin making copper chips in September 1999.
Mass production is slated for the end of the same year. The two companies
now lag behind large foreign competitors in technology, but they still
have the potential to surpass foreign companies in overall output in
