ChipMOS' November 2007 consolidated revenue included revenues of ChipMOS TECHNOLOGIES INC., ChipMOS Japan Inc., ChipMOS U.S.A., Inc., ChipMOS TECHNOLOGIES (H.K.) Limited, MODERN MIND TECHNOLOGY LIMITED and its wholly-owned subsidiary ChipMOS TECHNOLOGIES (Shanghai) LTD., and ThaiLin Semiconductor Corp.

ChipMOS today also revised its guidance for the fourth quarter of 2007 to reflect the rapid decline in DRAM pricing and inventory oversupply in the channel. The Company had expected fourth quarter 2007 revenue growth of 5% to 9% compared to the third quarter of 2007 revenue of NT$5,939.4 million or US$184.1 million. The Company now expects revenue in the fourth quarter of 2007 to be approximately flat to slightly up compared to the third quarter of 2007, with US GAAP gross margin on a consolidated basis for the fourth quarter of 2007 similar to the 24.2% achieved in the third quarter of 2007. ChipMOS continues to counter falling DRAM ASPs with execution on cost controls and diligence in its capital expenditures. Capex for the full year 2007 is expected to be approximately US$190 million compared to US$487 million for the full year 2006. The Company remains cautious but expects market conditions will improve during the next few quarters with DRAM pricing improving first due to manufacturing constraints. Demand and pricing remain stable and continue to improve in the Company's flash and driver IC segments.
