ABSTRACT:
The present invention is directed to a solid state image sensing device in which a transfer efficiency of a horizontal shift register is improved without decreasing an electric charge amount Q.sub.H treated by the horizontal shift register. Therefore, the solid state image sensing device becomes very useful when a peak value Ha of a transfer clock is lowered. According to an aspect of the present invention, a solid state image sensing device includes a horizontal transfer unit having a plurality of transfer electrodes formed of electrode pairs, each formed of a storage gate electrode and a transfer gate electrode and driving the plurality of transfer electrodes in two-phase fashion by the application of transfer clocks of the same phase to these electrode pairs to thereby transfer electrical charges from the vertical transfer unit to the horizontal direction. Transfer clocks of the same phase are applied directly to the transfer gate electrode and are also applied to the storage gate electrode via a resistor.
