Abstract:
1. A solid-state imaging device, comprising: a plurality of pixels that is formed in a semiconductor substrate in a two-dimensional array arrangement, each of the pixels comprising a photoelectric conversion region; and a plurality of color filters each of which is stacked on each of the pixels respectively, wherein the photoelectric conversion regions have a same depth irrespective of colors of the color filters stacked on the pixels, wherein the color filters comprise primary colors and include red filters, blue filters, and green filters, wherein a width of a deep portion of each of photoelectric conversion regions on which the red filters are stacked is more than a width of a shallow portion of each of photoelectric conversion regions on which the red filters are stacked, wherein a width of a shallow portion of each of photoelectric conversion regions on which the blue filters are stacked is more than a width of the deep portion of each of photoelectric conversion regions on which the blue filters are stacked, and wherein a width of a portion between the deep portion and a shallow portion of each of photoelectric conversion regions on which the green filters are stacked is more than a width of the deep portion and the shallow portion of each of photoelectric conversion regions on which the green filters are stacked.
