HSINCHU, Taiwan, April 10, 2013

HSINCHU, Taiwan, April 10, 2013 /PRNewswire-FirstCall/ --ChipMOS TECHNOLOGIES
(Bermuda) LTD. ("ChipMOS" or the "Company") (NASDAQ: IMOS) today reported its
unaudited consolidated revenue for the month and quarter ending March 31,
2013.

Revenue for the month of March 2013 was NT$1,612.3 million or US$54.1 million,
an increase of 19.0% from the month of February 2013 and an increase of 6.6%
from the same period in 2012. On a quarterly basis, revenue for the first
quarter of 2013 was NT$4,420.7 million or US$148.3 million, a decrease of 9.2%
from the fourth quarter of 2012 and an increase of 0.8% from the same period
in 2012. This is in-line with the Company's guidance that revenue for 1Q13
would be lower by approximately 9% to 13%, as compared to 4Q12. 1Q13 reflects
typical seasonality in the industry related to Chinese New Year and normal
customer demand patterns, slightly offset by continued growth in the Company's
LCD driver and mixed-signal business. All U.S. figures in this release are
based on the exchange rate of NT$29.81 to US$1.00 as of March 29, 2013.
