  • Patent number: 8946611
    Abstract: A color filter is formed using a simple manufacturing method, and bias application to a pixel separating electrode allows sensitivity in low illumination intensity to be improved. In a solid-state imaging element, in which a plurality of unit pixel sections are disposed two dimensionally on a side closer to a front surface of a semiconductor substrate or a semiconductor layer, each unit pixel section having a light receiving section for generating a signal charge by light irradiation, an adjoining unit pixel section is formed in the same color to allow for lesser alignment accuracy of the color filter. A pixel separating electrode is formed in the adjoining unit pixel section, and a signal charge is shared by bias application during low illumination intensity, thereby improving an effective photodiode area.
