Patent ID: 7821090

Claim:
A Solid-state image capturing apparatus, in which a plurality of solid-state image capturing devices having a plurality of light receiving sections laminated in a depth direction of a semiconductor substrate are arranged according to a sequence in a direction along a substrate surface; and of electromagnetic waves of incident subject light, electromagnetic waves having wavelength bands corresponding to depths of the respective light receiving sections are detected at the respective light receiving sections in accordance with wavelength dependency of optical absorption coefficient of a semiconductor substrate material of the semiconductor substrate; and signal charges are generated respectively, wherein, trench sections are provided in such a way that the trench sections each reach from a light incident surface or a substrate surface opposite from the light incident surface of the semiconductor substrate to locations of the respective light receiving sections that do not overlap each other in a plane view, wherein, readout gate electrodes are provided at each trench sections, and electric charge transfer sections are provided, the electric charge transfer sections being capable of transferring electric charges independently from the plurality of the light receiving sections via side wall portions of the respective trenches to the light incident surface side or the substrate surface side opposite from the light incident surface at the time of driving the readout gate electrodes.
