Abstract:
1. A solid-state imaging apparatus, comprising: a semiconductor substrate defining a two-dimensional surface; a multiplicity of photo electric conversion elements positioned on lattice points of a first lattice of a tetragonal matrix and of a second lattice of which each lattice point is positioned at a center of the first lattice in a light receiving region of the semiconductor substrate; a vertical electric charge transfer device having a plurality of vertical electric charge transfer channels arranged vertically between rows of the photo electric conversion elements and a plurality of transfer electrodes horizontally arranged over the vertical electric charge transfer channels; and reading out parts, each comprising a reading out electrode also serving as one of the transfer electrodes, corresponding to each one of the multiplicity of the photo electric conversion elements, and reading out a signal electric charge accumulated in the corresponding photo electric conversion element to the vertical electric charge transfer channels adjoining in a horizontal direction, wherein the reading out electrode and at least one of transfer electrodes adjoining to the reading out electrode are adjoining to same photo electric conversion element, and electric charge accumulated in each photo electric conversion element is transferred by every other line of vertical electric charge transfer channels in the vertical direction.
