  • Patent number: 6069374
    Abstract: A CCD type solid state imaging device including a plurality of vertically arranged light receiving elements, a plurality of vertical charge transfer electrodes associated with the light receiving elements and transfer channels through which signal electrical charges stored in the light receiving elements are readout and transferred in the charge transfer direction by the transfer electrodes. The present invention features that unlike the conventional CCD type solid state imaging device, the boundary line between at least a part of the vertical charge transfer electrodes and a part of the vertical charge transfer electrodes adjacent thereto is held aslant with respect to the transfer channels so that the vertical transfer efficiency of the device is increased without incurring a reduction in the amount of signal charges being handled and the readout of the signal charges stored in the light receiving elements to the transfer channels is performed more smoothly than the conventional device.
