Abstract:
1. A solid-state imaging apparatus comprising: an energy ray sensitive region, being formed on a front surface side of a semiconductor substrate, having a plurality of photoelectric conversion portions that are arrayed two-dimensionally, and generating charges in response to the incidence of energy rays; a plurality of transfer electrodes, each being disposed on the front surface side of the energy ray sensitive region with a first direction of the two-dimensional array as the longitudinal direction and transferring the charges in a second direction of the two-dimensional array; and voltage dividing resistors, disposed in correspondence to the transfer electrodes and each dividing a DC output voltage from a DC power supply to generate a DC output potential and providing the DC output potential to the corresponding transfer electrode, wherein a single potential gradient is formed for each set of photoelectric conversion portions arrayed in the second direction of the two-dimensional array below the plurality of transfer electrodes and increases gradually in a charge transfer direction.
