ChipMOS/Bermuda Announces Record Output

ChipMOS/Bermuda Announces Record Output Hsinchu, Taiwan, May 2, 2002 - ChipMOS TECHNOLOGIES (Bermuda) LTD. (Nasdaq: IMOS) ("ChipMOS/Bermuda") today announced that its Tape Carrier Package (TCP) output had reached a record high of more than 10 million pieces in April 2002 and is expected to reach 12 million pieces in May 2002. This significant milestone serves to highlight ChipMOS/Bermuda's position as one of Taiwan's leading TCP service providers.

"As a sign of the booming TCP market, ChipMOS/Bermuda has received a surge of orders from customers," said S.J. Cheng, Deputy Chairman and Chief Executive Officer of ChipMOS/Bermuda. "Some customers have even signed agreements with ChipMOS/Bermuda to protect their product delivery, with orders going as far into the future as the end of 2004."

Mr. Cheng continued, "We are pleased to see the continued growth of the TCP industry, especially in Taiwan. In order to better serve our customers, we have acquired more equipment to boost our TCP capacity. We believe that our current capacity will be sufficient to accommodate any further increase in demand."

ChipMOS/Bermuda's TCP/COF is currently volume produced at the inner lead pitch level of 45 micron, while its 35-micron technology is under development and is expected to be released for mass production by the fourth quarter of this year. The yields for both of its TCP testing and assembly operations are generally higher than 99.5% while the total yields including outgoing visual inspection are over 98.5%.

ChipMOS's Tape Carrier Package (TCP)/Chip On Film (COF) package provides both mechanical and electrical support to the LCD driver semiconductors between the LCD panel and the driving module for the application in flat panel displays. Furthermore, the driving module can be manufactured by using COF technology with finer inner lead pitch and more lead counts. Turn-key services for both TCP and COF packages, from gold bumping to final test, are available in current ChipMOS assembly lines.
