Abstract:
1. A solid-state imaging device comprising: a plurality of pixels; photodiodes which are formed separately for respective ones of the pixels arranged in a matrix shape on a light sensing surface of a semiconductor substrate; a signal reading unit which is formed on the semiconductor substrate and reads a signal charge generated and charged in the photodiodes or a voltage in accordance with the signal charge; an insulating film which is formed on the semiconductor substrate so as to cover the photodiodes and includes optical waveguides; color filters which are formed on the insulating film; and a plurality of on-chip lenses which are formed on the color filters, wherein in a layout, first pixel combinations and second pixel combinations are alternately arranged both in horizontal and vertical directions, the first pixel combination having a layout in which two green pixels are arranged both in the horizontal and vertical directions and a total of four pixels are arranged while provided with a green color filter as their color filter, the second pixel combination having a layout in which two pixels are arranged both in the horizontal and vertical directions, a total of four pixels are arranged, and two red pixels having red color filters and two blue pixels having blue color filters are arranged, wherein a first on-chip lens is shared by a plurality of green pixels, and a second on-chip lens is individually formed for a red pixel or a blue pixel.
