Abstract
A solid-state imaging device includes a light-receiving portion, an optical filter layer, and quantum dots. The light receiving portion, where a photoelectric conversion is carried out, is formed in a semiconductor substrate. The optical filter layer is directly formed on or formed through another layer on the surface of the semiconductor substrate in which the light-receiving portion is formed. Quantum dots having substantially equal diameters are formed in the optical filter layer. The quantum dots have higher refractive indexes than the refractive index of the optical filter layer in which the quantum dots are embedded.
