Abstract:
1. A solid-state imaging device comprising: a first metal interconnect layer between a substrate and a second metal interconnect layer, said second metal interconnect layer being between a first light-blocking film and said first metal interconnect layer; a second light-blocking film between said first light-blocking film and a third light-blocking film, said first light-blocking film and said third light-blocking film being in direct contact with said second light-blocking film, wherein said first metal interconnect layer is insulated from said substrate and said second metal interconnect layer, said second metal interconnect layer being insulated from said first light-blocking film and said second light blocking film; wherein said first light-blocking film is between said second light-blocking film and a black-level reference pixel part of the substrate; wherein a light-receiving pixel part the substrate is configured to receive incident light; wherein said third light-blocking film is between said second light-blocking film and a different metal interconnect layer, said different metal interconnect layer being insulated from said second light-blocking film and said third light-blocking film; wherein the first, second, and third blocking films are formed only in a single interlayer insulating film.
