Abstract
In order to implement a solid-state imaging device with high photo-sensitivity that includes a light collecting part which can reduce undesired variations during manufacture and which has high light collection efficiency, the solid-state imaging device includes: a photodiode () which converts incident light () into electric charges; a convex lens layer () which is formed above the photodiode () and through which the incident light is transmitted; and a concavo-convex lens layer () which is formed on and around the lens layer () and which collects the incident light and outputs the incident light to the lens layer (). A refractive index of the lens layer () is greater than a refractive index of the lens layer (). A thickness and a width of the lens layer () are set to achieve a predetermined focal length for light of a predetermined wavelength range. The lens layer is made of one of boron phosphorous silicon glass, tetra ethoxy silane, benzocyclobutene, and polyimide resin.
