SMIC WILL VIGOROUSLY DEFEND AGAINST NEW CLAIMS FROM TSMC AND ADVOCATES FAIR
COMPETITION

Shanghai, China, August 25th, 2004 Taiwan Semiconductor Manufacturing Company
Ltd. ("TSMC") has recently filed a proceeding against Semiconductor
Manufacturing International Corporation (SMIC; NYSE: SMI and HKSE: 981) with the
United States International Trade Commission (the "ITC"). In this ITC
proceeding, TSMC has alleged substantially the same trade secret
misappropriation claims which are currently pending before the California State
Court, and patent infringement claims regarding three patents which are the
subject of a new suit TSMC filed concurrently with the ITC proceeding, against
the Company in the U.S. District Court for the Northern District of California.

As with the previous claims in TSMC's other lawsuits, SMIC is in the process of
conducting an investigation of the new claims and will assess and formulate its
strong defenses to the new claims.

SMIC emphasizes that it respects the intellectual property of others. Given
SMIC's reputable technology partners and customers, and strong experienced
in-house technical team, SMIC's success has been accomplished without the need
to misappropriate any third party's trade secrets.

SMIC welcomes all semiconductor companies including those from Taiwan to jointly
develop the rapidly growing China semiconductor market. Advocating fair and
friendly competition, SMIC is willing to share its China experience.
