Abstract:
1. A backside-illuminated imaging device that performs imaging by illuminating light from a back side of a semiconductor substrate to generate electric charges in the semiconductor substrate based on the light and reading out the electric charges from a front side of the semiconductor substrate, the backside-illuminated imaging device comprising: a plurality of charge accumulating areas in the semiconductor substrate which accumulate the electric charges; and a plurality of filters above a backside surface of the semiconductor substrate corresponding to the respective charge accumulating areas, wherein the plurality of filters includes different color filters which transmit different color components of the light from one another and luminance filters other than the color filters each having a spectral characteristic correlated with a luminance component of the light, the plurality of charge accumulating areas includes first charge accumulating areas corresponding to the respective color filters, and second charge accumulating areas corresponding to the respective luminance filters, and the second charge accumulating areas each include a third charge accumulating area such that the second charge accumulating areas each have a size larger than a size of the first accumulating areas.
