    A comment in here, about a colour filter sounds a bit like Foveon.

    IBM announced a CMOS image sensor development and manufacturing
    collaboration with Kodak in September, 2004, which included the
    license of Kodak CMOS image sensor fabrication intellectual property
    to IBM. Kodak this week announced new three- and five-megapixel CMOS
    image sensors qualified and manufactured for Kodak by IBM's
    semiconductor facility in Burlington, Vermont, that utilize this

    IBM's foundry offering is based on IBM's 0.18-micron copper CMOS
    manufacturing process, available at its Burlington facility, that
    features an integrated design kit, including a 4-transistor, 3-micron
    pixel with pinned diode, and access to IBM's image sensor circuit

    IBM's CMOS technology delivers image sensors with one of the
    industry's best "dark current" performance, or the ability to capture
    photos in low-light situations, a key feature for consumer
    applications such as camera cell phones.

    Image quality can also be improved through IBM's ability to produce
    sensors featuring an ultra-thin, 2.5-micron copper stack incorporating
    an on-chip color filter and microlens. The copper stack is
    approximately 30 percent thinner than standard aluminum-based
    processes, which can result in significant improvements in light
    collection efficiency (quantum efficiency) for improved picture
    quality in low light. In addition, IBM's angle response performance --
    important when using lenses with wider apertures -- delivers superior
    photo resolution and sharpness.

    Currently, IBM is the only foundry supplier producing image sensors
    based on 0.18-micron copper process technology. IBM was the first
    semiconductor manufacturer to introduce copper technology and foundry
    clients can benefit from the company's successful copper production
    track record. In addition, IBM offers access to industry-recognized
    design kits and a comprehensive circuit library.

    "IBM is bringing its extensive copper semiconductor process experience
    to bear on the CMOS image sensor market, offering clients what we
    believe is the best foundry technology available today," said Tom
    Reeves, vice president, semiconductor products for IBM Systems &
    Technology Group. "Our innovative technology produces sensors with
    excellent color accuracy, low noise and very competitive low-light
    performance that can help clients differentiate their products in this
    competitive and growing consumer market."

    "We are pleased to see Kodak's image sensor technology at the heart of
    IBM's new foundry offering," said Chris McNiffe, General Manager of
    Kodak's Image Sensor solutions business. "Our collaboration with IBM
    has been extremely successful thus far, leveraging our respective
    strengths in imaging and semiconductor manufacturing."

    Image sensor market growth is shifting from charged coupled devices
    (CCDs) to CMOS-based sensors. CCDs have been the predominant
    technology used in digital imaging products due to improved picture
    quality, but CMOS technology benefits can include low power, high
    integration and low production costs compared to CCDs, all important
    benefits for consumer applications. IBM's foundry technology roadmap
    will enable CMOS-based image sensors that approach the size and
    performance of CCD pixels offered today.

  2. I don't think so - they would make a lot more fuss about having three
    sensitive layers etc. They do claim higher QE which is a good thing for
    lower noise (at a particular exposure), particularly if they can increase
    well capacity at the same time.
