TSMC Monthly Sales Report - January 2004 Hsinchu, Taiwan, February 9, 2004 - Taiwan Semiconductor Manufacturing Company Ltd. (TSMC) ("the Company") (TAIEX: 2330, NYSE: TSM) today announced that net sales for January 2004 totaled NT$19,156 million, an increase of 45.9 percent over the same period last year. On a sequential basis, January 2004 sales increased one percent. Ms. Lora Ho, TSMC spokesperson, vice president and chief financial officer, noted that, "TSMC's January 2004 sales increased as a result of higher wafer shipments compared to December 2003. In addition, due to a fewer number of working days in February, it is expected that TSMC's February 2004 sales would decline slightly. However, the Company's first quarter 2004 guidance, which was announced on January 29, remains unchanged." # # # Sales Report: (Unit: NT$ million) ------------------------------------------------------------------------------- 2004/(1)/ 2003 Growth Rate ------------------------------------------------------------------------------- Net Sales for January 19,156 13,129 45.9% ------------------------------------------------------------------------------- (1): Year 2004 figures have not been audited.
