Fairchild Semiconductor International Inc said the revised unsolicited offer it received from China Resources Microelectronics Ltd and Hua Capital Management Co Ltd last week is superior to that of ON Semiconductor Corp. Fairchild said on Tuesday its board still supports the deal with ON Semiconductor and is not making any recommendation related to the revised proposal. ON Semiconductor in November agreed to buy Fairchild Semiconductor for $2.4 billion to bolster its business of making power-management chips.
