TSMC Ships One-Millionth 12-Inch 90NM Wafer Fast ramping process reaches milestone in 4½ years

Hsin-Chu, Taiwan -- December 3, 2007 --- Taiwan Semiconductor Manufacturing Company, Ltd. (TSE: 2330, NYSE: TSM) today announced that it has shipped its one-millionth 12-inch 90-nanometer (nm) wafer in record time. The record was reached in just 53 months, surpassing the 58 months it took the 0.13-micron process to reach that milestone.

TSMC Vice President, Corporate Development, Jason Chen credits the fast ramp of 90nm process to a number of factors, including a comprehensive IP and library portfolio and an accelerated yield learning curve. He also cited the TSMC GigaFab manufacturing strategy that enables faster qualification and assured compatibility that allows faster time-to-market and time-to-volume.

TSMC’s 90nm process covers a rich set of technology options including mixed signal, RF, CMOS image sensor, automotive, and embedded DRAM. The robust technology platform supports broad range of market segment demand such as hard disk drives, wireless LAN, Bluetooth, cellular RF, digital set-top boxes, digital TV, Blueray DVD, CMOS image sensors, flash controller and a variety of automotive applications.

About the 90nm Process

TSMC’s 90nm process family has low power (LP), general purpose (G), and high performance (GT) offerings. Features include multiple ultra-low, low, standard and high Vt options. Core operating voltages range from 1.0 to 1.2 volts and I/O voltages range from 1.8V to 3.3V. An extensive portfolio of process proven, silicon validated libraries and IP from TSMC’s internal design team and third-part partners is also available.

The 90nm process runs in both TSMC GigaFabs, Fab 12 and Fab 14. The Company is also developing an enhanced 90nm process, which should deliver even greater benefits in performance, cost, and efficiency.
