Abstract:
A CCD type solid state image pickup device, comprising:a semiconductor substrate; a number of photoelectric conversion elements formed in and on said semiconductor substrate in a matrix configuration of rows and columns; a plurality of VCCDs each having a vertical channel region formed in said semiconductor substrate along each column of said photoelectric conversion elements, and a first set of charge transfer electrodes formed above the vertical channel region; an HCCD having a horizontal channel region formed in said semiconductor substrate and coupled to one ends of said VCCDs, and a second set of charge transfer electrodes formed above the horizontal channel region; a floating diffusion formed in said semiconductor substrate and coupled to one end of said HCCD; and an output amplifier including a pair of source/drain regions and an input gate electrode traversing above a region between the pair of source/drain regions, the input gate electrode having a portion extending at least near to said floating diffusion, and the input gate electrode being thinner than the first and second sets of charge transfer electrodes.
