"The GH1, which uses ISOCELL Plus technology, has a reported resolution of 7968 x 5840 (43.7 MP). The Tetracell color filter array is in use and manipulating the contrast on our optical images we can see an artifact of the Super-PD phase detection autofocus (PDAF) pixel pattern. We have documented Samsung using masked and 2x1 on-chip lens (OCL) PDAF on different 0.8 µm generation sensors. Here at the 0.7 µm generation we expect only 2x1 OCL PDAF will be used, as on the GH1.
One other topic to mention on this world’s first 0.7 µm pixel sensor is the stacked chip interconnect strategy. The through silicon via (TSV) arrays visible in our die photograph show us immediately that Samsung has not yet adopted a Cu-Cu direct bond interconnect strategy as we have observed in Sony and TSMC fabricated imagers."
