  • Patent number: 8189083
    Abstract: A solid-state imaging device includes a semiconductor substrate having a pixel region including a photoelectric conversion portion, a wiring portion including a conductor line and disposed on the semiconductor substrate with an insulating film therebetween, a metal pad connected to the conductor line, a pad-coating insulating film coating the metal pad, and a waveguide material layer. The wiring portion and the pad-coating insulating film each have an opening therein over the photoelectric conversion portion, and the openings continue from each other to define a waveguide opening having an open side and a closed side. The waveguide material layer is disposed in the waveguide opening and on the pad-coating insulating film with a passivation layer therebetween. The pad-coating insulating film has a thickness of 50 to 250 nm and a face defining the opening. The face is slanted so as to diverge toward the open side of the opening.
