In a research memo published online, FBR Capital analyst Craig Berger notes that Sony may be the one picking up the order for manufacturing the camera CMOS sensor for the iPhone 5.
Forbes' Eric Savitz writes that Omnivision may be having some technical issues which might put its "iPhone socket supplier status" at risk, and prompt Apple to switch to Sony instead.
According to Berger, Omnivision was going to use its BSI-2 technology, which uses a "1.1-micron pixel architecture allowing for low-light sensitivity and accurate color reproduction for better overall image quality", a world first.
TSMC was going to use a 65nm manufacturing process on 300mm wafers but yield rates have so far been unacceptably low for it to be commercially viable.
It looks therefore increasingly likely that Sony will grab up to 90 per cent of the contract to build the eight-megapixel CMOS image sensors for the iPhone 5, which is estimated to be worth around $500 million for this year alone.
Omnivision may be used as a backup supplier once it manages to solve its present issues. The iPhone 5 is rumoured to be physically different to the iPhone 4 with a bigger 4-inch screen, a thinner body, a Qualcomm baseband chip, a dual core Apple A5 SoC and a better battery.
