Patent ID: 7767485

Claim:
A solid-state imaging device, comprising: a semiconductor substrate including a photodiode formed in an upper face; a microlens provided on the semiconductor substrate at a position corresponding to the photodiode; an adhesive layer provided on the semiconductor substrate not to cover the microlens, the adhesive layer having a frame-like configuration; a low refractive index layer provided on the semiconductor substrate to cover the microlens, the low refractive index layer formed from a low-refractive-index material having a refractive index lower than a refractive index of a material forming the microlens, the low refractive index layer having a rectangular parallelepiped configuration surrounded by the adhesive layer, a height of the low refractive index layer being same as a height of the adhesive layer; a transparent substrate covering the adhesive layer and the low refractive index layer, the transparent substrate contacting both an upper face of the adhesive layer and an upper face of the low refractive index layer, and the transparent substrate adhered to the semiconductor substrate by the adhesive layer; an interconnect layer provided on a lower face of the semiconductor substrate; and an external connection member bonded to a lower face of the interconnect layer.
