Abstract :
A 2/3-in optical format 2 M pixel STACK-CCD imager has been developed. The STACK-CCD imager, overlaid with an amorphous silicon photoconversion layer, realizes a large signal charge handling capability of 1.0×105 electrons, a -140 dB smear noise and a 90 dB dynamic range with a newly introduced device configuration and its unique operation. The 5.0 μm(H)×5.2 μm(V) unit pixel imager with sufficiently low image lag has been realized by a novel bias charge injection scheme These device performances are the best ever achieved by a CCD HDTV imager. This is the first such imager satisfying the device performances required for a practical use 2/3-in 2 M pixel HDTV imager
