ChipMOS Taiwan Announces an increase of 20%~25% Price-raising for LCD Driver IC Assembly and Testing Services Hsinchu, Taiwan, Oct 07, 2003 - ChipMOS TECHNOLOGIES (Bermuda) LTD. (Nasdaq: IMOS) ("ChipMOS Bermuda") today announced that its 70% owned subsidiary, ChipMOS TECHNOLOGIES INC. ("ChipMOS") plans to raise 20 - 25% of it's service prices of LCD driver IC assembly and testing. The prices adjustment is to reflect the fact that the capacity for LCD driver IC assembly and testing service has been overbooked and ChipMOS faces heavy pressure to expand it's production capacity under customers' continuous requests.

Owing to it's lightweight, low profile, power saving and no radiation, LCD panel has become the mainstream of computer monitor since 2002. Upcoming this year, LCD TV is going to replace current CRT TV as home entertainment appliance. The demand for LCD driver ICs thus increases with the demand of LCD panels resulting in fully operating of ChipMOS's LCD driver IC assembly and testing production lines since the fourth quarter of 2002.

To maintain its commitment of continuous providing advanced assembly and testing services to it's customers, ChipMOS decided to expand its LCD driver IC assembly and testing capacity, TCP and COF, to 25 million pieces per month in the first quarter of next year. ChipMOS also has close tie with some of its customers to sign business contract to guarantee next four years capacity supply. In the mean time, raise of LCD driver IC assembly and testing price has been accepted by some major customers.

Currently, ChipMOS has Taiwan's largest LCD driver IC assembly and testing capacity of around 24 million pieces monthly. In addition, ChipMOS has successfully developed COF (Chip on Film) assembly technology with inner lead pitch below 40 mm. COF technology can increase pin integration to downsize chips for portable consumer products. ChipMOS will become the leading company in the next generation in providing LCD driver IC assembly and testing services.
