TSMC Monthly Sales Report - February 2003

Hsinchu, Taiwan, March 7, 2003– Taiwan Semiconductor Manufacturing Company Ltd. (“TSMC” or “the Company”) (TAIEX: 2330, NYSE: TSM), today announced that net sales for February 2003 totaled NT$12,345 million; revenues for January through February 2003 were NT$25,474 million.

Mr. Harvey Chang, TSMC spokesperson and senior vice president, said that because February was a short month that also included the Chinese Lunar Year holidays, unit sales in February 2003 were less than those in January. As a result, net sales for February 2003 decreased by a slight 6.0% compared to January 2003. On a year-over-year basis, net sales for February 2003 increased 7.6%.

Mr. Chang also noted that TSMC’s revenue will for certain touch bottom in the first quarter of 2003 and its monthly sales for the second quarter of 2003 are expected to increase sequentially. TSMC 2003 first quarter results are expected to be better than were forecast in its institutional investor conference on January 28, 2003. The utilization rate for the first quarter of 2003 is expected to be a few percentage points higher than the previously-forecast 60% range, showing a clear sign of stabilization.
