Here is an interesting article on agreements between Kodak and IBM.
http://lfw.pennnet.com/articles/article_display.cfm?PUBLICATION_ID=12&ARTICLE_ID=212305&pc=enl
The interesting part is Kodak gets a world class fine line (0.18um) , high
speed (copper interconnect) CMOS manufacturing process, while IBM gets rights
to "pinned" photodiode and switch patents used in Kodak CCD's. The claim is
good performance from smaller size pixel CMOS sensors, but with performance of
smallest pixel CCD devices. They also get access to Foveon technology (through
National Semi imager agreement) which may be helpful also for small area
devices, for reducing the off axis effects of wide angle lenses etc.
