  • Solid-state imaging device, method of manufacturing solid-state imaging device, and electronic equipment
    Patent number: 8994858
    Abstract: A solid-state imaging device includes a photoelectric transformation portion and a micro lens, the micro lens has a first refractive index layer which is a first refractive index and a second refractive index layer which is a second refractive index different from the first refractive index, wherein the micro lens is configured so that a vertical cross section, which is a surface perpendicular to the capturing surface, has a rectangular shape, wherein each of the first refractive index layer and the second refractive index layer are arranged adjacent to each other in a direction along the capturing surface, and an interface between the first refractive index layer and the second refractive index layer in the vertical cross section is formed so as to follow a direction perpendicular to the capturing surface.
