A 600 (H) X 502 (V) 1/2 Frame Transfer CCD Image Sensor

Dark current and some other characteristics on a 1/2" frame transfer CCD ( FICCO ) image sensor with 600 (H) X 502 (V) pixels are described. It is generally said that high sensitivity and high horizontal resolution are obtained for the CCD image sensor of a frame transfer organization. But the smaller the pixel size is, the less some characteristics become. This paper reports that there is a close correlation between dark currnt and the surface state density, which can be reduced by introducing the suitable post metallization annealing. As a result, the S/N of video signal under low intensity of illumination is can be enhanced on the occasion of the reduction in the pixel size.
