Abstract
In a solid-state image sensor device, the efficiency of light collection to a light-receiving region of a photodiode PD through a microlens is enhanced by arranging a wiring line configuration. Each of the first metal layer and the second metal layer is arranged to have a ring-like portion formed along a profile of the light-receiving region of the photodiode PD in a fashion that an upper position over the photodiode PD is surrounded by the first and second metal layers and a third metal layer.
