ChipMOS FILES PATENT INFRINGEMENT SUITS AGAINST WALTON ADVANCED

ENGINEERING INC AND WALTON CHAINTECH CORPORATION

Hsinchu, Taiwan, September 19, 2007 – ChipMOS TECHNOLOGIES (Bermuda) LTD. (“ChipMOS” or the “Company”) (Nasdaq: IMOS) filed two lawsuits on September 19, 2007 in Kaohsiung and Banciao District Court against Walton Advanced Engineering, Inc. (“Walton”) and Walton Chaintech Corporation (“Walton Chaintech”), alleging their infringement of one of ChipMOS’ package related patents which are used for DDR II SDRAM devices.

ChipMOS obtained from the retail market several “APOGEE” branded memory modules manufactured by Walton Chaintech, which are believed to contain memory ICs assembled by Walton, and sent these modules to a professional appraisal institution for investigation. ChipMOS decided to file the litigation based upon the report of this professional appraisal institution, which concluded that the package device employed on the aforementioned modules infringed ChipMOS R.O.C. patent no. 177516 “Method for Mounting a Chip for Improving Bonding and Positioning” .

ChipMOS treats intellectual property as one of the Company’s important resources. To protect its patents and its shareholders, and to seek a fair return on its efforts in R&D activities, ChipMOS decided to file the patent infringement lawsuits against Walton and Walton Chaintech, each seeking NT$15 million in monetary damages at the initial stage for the losses ChipMOS suffered as well as a court order prohibiting Walton and Walton Chaintech from using the allegedly infringing technology.
