Abstract:
1. A method of producing a solid-state imaging device, comprising the steps of: forming a plurality of light receiving portions arranged in a first direction and a second direction that is perpendicular to the first direction; forming a plurality of transfer channels extending in the second direction, each being positioned between neighboring light receiving portions; forming a plurality of first transfer electrodes positioned over the plurality of transfer channels; forming a plurality of second transfer electrodes positioned over the plurality of transfer channels, the plurality of second transfer electrodes being formed in a layer in which the plurality of first transfer electrodes are formed, the plurality of second transfer electrodes being separate from the plurality of first transfer electrodes; forming a plurality of third transfer electrodes over the plurality of transfer channels, the plurality of third transfer electrodes being separate from the plurality of first transfer electrodes and the plurality of second transfer electrodes; and forming a plurality of low-resistance wirings having a resistance lower than a resistance of any of the plurality of first transfer electrodes, wherein,
