Samsung publishes a promotional video explaining its ISOCELL pixel advantages:

  1. ISOCELL is just a fancy marketing term for Deep Trench Isolation (DTI), which Sony Semiconductor has been using for at least a decade.

    Marvin, please notice that DTI for image sensors was published first in 2007 by Samsung in cooperation with a Korean University, and around the same time by IMEC.

    B.J. Park et.al. : Deep Trench isolation for Crosstalk Suppression in Active Pixel Sensors with 1.7 um Pixel Pitch, published in Japanese Journal of Applied Physics, 2007. IMEC was a few months later, so I guess that IMEC was not aware of the work that was going on in South-Korea.

    Here is the reference of IMEC, and actually I mixed up the two dates. It turns out that IMEC was first with their publication, just a couple of months.
    K. De Munck et.al : “High performance hybrid and monolithic backside thinned CMOS imagers realized using a new integration process”, Proceedings of the IEEE International Electron Devices Meeting, p139-142, Dec. 11-13, 2006, San Francisco, US.

  6. Nevertheless, I am not so sure about the higher color fidelity, since for an appropriate color de-Bayering it is required that there is some spectral "crosstalk", but nice animation though.
