Abstract:
1. A solid-state image sensor having a plurality of pixels with corresponding plurality of photoelectric conversion elements, the plurality of pixels and corresponding photoelectric elements being disposed in an array on a plane having an x-axis and a y-axis, the solid-state image sensor comprising: a plurality of lower electrodes that respectively corresponds to the plurality of pixels; a photoelectric conversion layer stacked on the lower electrodes; a sensor region in which each of the plurality of photoelectric conversion elements is positioned, the sensor region has a center point positioned at the intersection of the x-axis and the y-axis; an upper electrode stacked on the photoelectric conversion layer; a wiring portion capable of supplying a voltage to the upper electrode to generate an electric field between the upper electrode and the lower electrode; and a plurality of connection portions connecting the wiring portion and the upper electrode, the plurality of connection portions being disposed in a circumference region which is a region other than the sensor region, each of the photoelectric conversion elements including one of the lower electrodes, a part of the photoelectric conversion layer corresponding to the one of the lower electrodes and a part of the upper electrode corresponding to the one of the lower electrodes, wherein the plurality of connection portions is disposed in a symmetrical arrangement with respect to the x-axis and also in a symmetrical arrangement with respect to the y-axis so as to achieve a four-fold symmetrical arrangement relative to the center point of the sensor region, and wherein the upper electrode envelopes the plurality of connection portions.
