ChipMOS Bermuda Announces Unaudited Consolidated Results for the Fourth Quarter of 2003 and the Year of 2003Hsinchu, Taiwan, February 10, 2004-ChipMOS TECHNOLOGIES (Bermuda) LTD. (Nasdaq: IMOS) ("ChipMOS Bermuda") today announced its unaudited consolidated results for the fourth quarter and the year ended December 31, 2003.

Revenue for the fourth quarter 2003 was NT$2,484 million, an increase of 37% from NT$1,813 million for the same period in 2002 and an increase of 2% from NT$2,438 million for the third quarter of 2003. The gross margin for the fourth quarter of 2003 was 28% compared to 1% for the same period in 2002 and 20% for the third quarter of 2003. Net income for the fourth quarter of 2003 was NT$365 million or NT$6.18 per common share, compared to a net loss of NT$235 million or NT$4.00 per common share for the same period in 2002 and a net income of NT$173 million or NT$2.95 per common share for the third quarter of 2003.

For the fiscal year ended December 31, 2003, ChipMOS Bermuda had revenue of NT$8,956 million, an increase of 37% from NT$6,526 million in 2002, and a net profit of NT$418 million, compared to a net loss of NT$970 million in 2002. The net income per common share for the twelve months ended December 31, 2003 was NT$7.10, compared to a net loss per common share of NT$16.49 in 2002.

S.J. Cheng, Deputy Chairman and Chief Executive Officer of ChipMOS Bermuda, remarked, "We broke even in the third quarter of 2003 and continued to make profit in the fourth quarter of 2003. Effective October 2003, we raised the price of our LCD driver IC assembly and testing services between 20% and 25%, which contributed to the growth of our revenue and gross margin in the fourth quarter of 2003. Total revenue of NT$8,956 million has been generated in 2003-the highest annual revenue we have generated since our incorporation. In response to the slowdown of the global economy and the subdued demand for semiconductors in 2000 and 2001, we tried to enhance our competitiveness and market share in particular through investing in back-end or back-end related companies in the last two years. The operating results of those companies have improved and some of those companies made a profit in 2003. We are pleased what we achieved in 2003 met our expectations and we are confident that ChipMOS Bermuda is well positioned to take on future opportunities and challenges."

Outlook

The demand for our LCD driver IC assembly and testing services has been increasing in line with the increase in demand for TFT LCD displays. LCD driver ICs are primarily used in handheld electronics, cellular phones, flat-panel displays and notebook computers. In the fourth quarter of 2003, we packaged most of the LCD driver IC using tape carrier package, or TCP, technology and chip-on-film, or COF, technology. Demand for COF packages has particularly been increasing, reaching 12% of our total LCD driver IC delivery in December 2003. Based on current market conditions, we believe that the demand for COF packages will continue to increase in the first quarter of 2004. As the prices for LCD driver IC continue to rise, in particular for COF packages, which have a higher margin, we expect our LCD driver IC operation to contribute more to our revenue and profit in the first quarter of 2004. In order to meet customer demands, we plan to further expand our capacity of our LCD driver IC operation to the scale of 32 million pieces per month by the end of the second quarter of 2004.

Due to the growth in handheld electronics and IA (Information Appliances) products, there has been a market shortage of flash memory since mid 2003. As a result, the demand of IDM (Integrated Device Manufacturer) customers for our assembly and testing services for flash memory products has increased, while the demand for SRAM and DRAM kept flat. Accordingly, we have allocated more capacity to our assembly and testing services for flash memory. We currently believe that our revenue from assembly and testing services for flash memory will increase in the first quarter of 2004.

Our Shanghai operation has increased its capacity to 6 million pieces per month by the end of December 2003. This capacity increase is expected to improve the gross margin of our China operation. Further expansion is expected to occur mainly in two areas, namely, assembly and testing of memory and LCD driver IC, and will be implemented in line with market demands.
