"IBM CIMG7SF provides a competitive sub 3.0 μm, 4-transistor (4T) pixel architecture with an optimized transfer gate, which is suited for mobile camera phone and digital still-camera applications. CIMG7SF also provides large reference pixels for high-end digital still camera and emerging applications. The offering includes state-of-the-art microlenses and color filters for exceptional quantum efficiency and angle response, along with pinned photodiode technology for reduced dark current. This technology uses aluminum wiring for the last metal level and copper wiring for the remaining metal levels. With thin back-end-of-line (BEOL) metal stacks and improved dielectric tolerance, CIMG7SF is suited for multiple imaging applications."
