Digitimes posts an article on Taiwan and China CIS foundries. Few quotes:
"TSMC has been the major CIS module production partner for OmniVision although the module vendor is also outsourcing part of its production to China-based XMC. However, the partnership between TSMC and OmniVision may change in the future as China-based Hua Capital, an investment firm, has offered a bid to acquire OmniVision, indicated the sources.
UMC has tied up with STMicroelectronics to develop 65nm BSI CIS technology and is currently producing BSI products at its Fab 12i in Singapore."
