Interesting discussion of camera sensor vendors:

They estimate 50+ imager chip manufacturers, although many are fabless.
(That is they design devices themselves, but get contract semiconductor
"fabricators" to build. )
Some like Kodak use both approaches: TMSC a large Taiwan fab makes the Kodak
CMOS sensors, while kodak makes bipolar CCD's themselves.
