Patent ID: 8884348

Claim:
A solid-state imaging device comprising: an imaging area which includes pixels of three colors of R, G and B, each of the pixels including: a first photodiode which performs photoelectric conversion for incident light; a first read transistor which is connected to the first photodiode and reads a signal charge obtained by the photoelectric conversion by the first photodiode; a second photodiode which has a photosensitivity lower than a photosensitivity of the first photodiode, performing photoelectric conversion for incident light; a second read transistor which is connected to the second photodiode, reading a signal charge obtained by the photoelectric conversion by the second photodiode; a floating diffusion layer provided between the first photodiode and the second photodiode, and which is connected to the first and the second read transistors, storing the signal charges; a reset transistor which contacts the floating diffusion layer in a direction perpendicular to a direction in which the first and the second photodiodes are arranged and which resets a potential of the floating diffusion layer; and an amplifying transistor which contacts the floating diffusion layer in a direction perpendicular to a direction in which the first and the second photodiodes are arranged and which amplifies the potential of the floating diffusion layer; a plurality of color filters which include color filters for R, G and B, which have color filters for R and B and a color filter for G having different spectrum transmission characteristics; and a plurality of microlenses which includes a first and a second microlenses which are provided for the color filters, respectively, collect light and apply the light onto the imaging area, wherein the relationship AREA 1 <AREA 2 is satisfied, where AREA 1 represents an area of the first microlens which is provided for the color filter for G and collects light onto the second photodiode and, AREA 2 represents an area of the second microlens which is provided for the color filters for R and B and collects light onto the second photodiode; the color filter for G has a spectrum transmission characteristic of G, and the color filters for R and B have spectrum transmission characteristics of colors other than G.
