                  TSMC October 2003 Sales Exceeded NT$ 20 Billion
               Set a New Record High for a Third Consecutive Month

Hsinchu, Taiwan, November 7, 2003 - Taiwan Semiconductor Manufacturing Company
Ltd. ("TSMC" or "the Company") (TAIEX: 2330, NYSE: TSM) today announced that net
sales for October 2003 totaled NT$20,304 million, a new record high for a third
consecutive month. The October results also marked the first time that the
Company's monthly sales exceeded NT$ 20 billion.

TSMC October 2003 net sales increased 7.4 percent from September 2003 sales on a
month-over-month basis. Compared to the same period a year ago, October 2003 net
sales increased 33.3 percent. Revenues for January through October 2003 totaled
NT$164,429 million, an increase of 21.8 percent over the same period in 2002.

Ms. Lora Ho, TSMC spokesperson and vice president, noted that the Company's
October 2003 wafer shipments grew over September 2003 due to increased customer
demand in anticipation of the Christmas holiday season, especially for consumer
and communication products. As a result, the Company's October 2003 sales
increased sequentially.
