Patent ID: 7781798

Claim:
A solid-state image pickup device, comprising: a light receiving pixel section formed on a semiconductor substrate; a black level reference pixel section formed on said semiconductor substrate; a multi-layer wiring line section formed on said semiconductor substrate including said light receiving pixel section and said black level reference pixel section; said multi-layer wiring line section including, an insulating layer formed on said semiconductor substrate; and a plurality of metal wiring line layers formed in said insulating layer and including first, second, third and fourth metal wiring line layers; a first light blocking film formed by disposing some of a plurality of first metal wiring lines formed from said first metal wiring line layer in a predetermined spaced relationship from each other and in a plurality of rows above said black level reference pixel section; a second light blocking film formed by disposing some of a plurality of second metal wiring lines formed from said second metal wiring line layer above said first metal wiring line layer between and above said first metal wiring lines above said black level reference pixel section; a third light blocking film formed by disposing some of a plurality of third metal wiring lines formed from said third metal wiring line layer above said second metal wiring line layer in a predetermined spaced relationship from each other and in a plurality of rows in a direction perpendicular to said second light blocking film above said black level reference pixel section; and a fourth light blocking layer formed by disposing some of a plurality of fourth metal wiring lines formed from said fourth metal wiring line layer above said third metal wiring line layer above and between said third metal wiring lines above said black level reference pixel section.
