Abstract
PURPOSE:To obtain an element of high integration degree, small size and low energy consumption, by decreasing, in a solid state image pick-up device, the number of electrodes and the step numbers of driving circuits. CONSTITUTION:A thick insulating layer 30 is formed on a P type semiconductive substrate 40 through the LOCOS process to define active regions 21, 22, 23, 24 becoming picture elements. At the parts 21a, 23a directly beneath an accumulation electrode 2Y at the picture elements 21, 23, an impurities doping 31 is performed injecting arsenic. Thus, the threshold value voltage of the parts 21a, 23a shifts toward the plus voltage direction from that of the parts, 22, 24. Then, by applying V1 to a detecting electrode 2X and V3 to the accumulation electrode 2Y, wells of various depths are formed as shown by broken lines to accumulate the electric charge q generated by the photoelectric, conversion. To read out the signals of two picture elements one by one, it is enough to apply the voltage changeable steplike into two values on a vertical bus line R1 connected in parallel to the accumulation electrode 2Y. Thereby, a plurality of picture element signals lined horizontally at one line can be read out by one step of the shift registor.
