Abstract:
1. A solid state imaging device comprising: a plurality of photodiodes that have been arranged two-dimensionally with spacing between each other, in a semiconductor substrate, each of the photodiodes having a function of photoelectric conversion; a plurality of kinds of color filters, each of the color filters having been formed above the respective photodiodes and transmitting light that has, for each kind, a different peak wavelength; a plurality of substrate contacts that have been respectively arranged in vicinity of some or all of the plurality of photodiodes, so as to apply a reference voltage to the semiconductor substrate, wherein the plurality of photodiodes include photodiodes that belong to a first group and photodiodes that belong to a second group such that color filters above the photodiodes of the first group have a longer transmission peak wavelength, and color filters above the photodiodes of the second group have a shorter transmission peak wavelength, and a distribution of the substrate contacts is denser in vicinity of the photodiodes in the first group than in vicinity of the photodiodes in the second group.
