        TSMC Revises Upwards Its Guidance for the Fourth Quarter of 2002

Hsin-Chu, Taiwan, November 22, 2002 - Taiwan Semiconductor Manufacturing
Company Ltd. ("TSMC" or "the Company") (TAIEX: 2330, NYSE: TSM) today revised
upwards its guidance for the fourth quarter of 2002, among which the wafer
shipment and the utilization rate are expected to be higher than those
forecasted earlier at TSMC's third quarter institutional investor conference.

Mr. Harvey Chang, TSMC Spokesman, noted that both TSMC's wafer shipment and
utilization rate show considerable improvement over the guidance forecasted
previously, due to the recent pick up in the PC demand and the increased demand
for communication products for Christmas season. As a result, TSMC revised
upwards its forecast for the fourth quarter of 2002. The revised forecast
indicated that the Company's wafer shipment for the fourth quarter of 2002 would
approximately equal to that for the third quarter of 2002. The Company's
utilization rate is expected to be close to 60 percent. In addition, the average
selling price (ASP) is expected to remain about the same as that announced
earlier at TSMC's third quarter institutional investor conference.
