Abstract:
1. A solid-state image sensor device, comprising: a photodiode; first and second wiring lines disposed at mutually adjacent positions in a first metal layer, each of the first and second wiring lines being arranged to extend in a first direction and to have a bowed portion bending along a profile of a light-receiving region of the photodiode; third and fourth wiring lines disposed at mutually adjacent positions in a second metal layer, each of the third and fourth wiring lines being arranged to extend in a second direction different from the first direction and to have a bowed portion bending along the profile of the light-receiving region of the photodiode; and a microlens; wherein the bowed portions of the first and second wiring lines are configured to surround the profile of the light-receiving region of the photodiode in the form of a ring, wherein the bowed portions of the third and fourth wiring lines are configured to surround the profile of the light-receiving region of the photodiode in the form of a ring, and wherein light collected through the microlens is introduced to the light-receiving region of the photodiode by passage through the inside of the ring formed by the bowed portions of the first and second wiring lines and the inside of the ring formed by the bowed portions of the third and fourth wiring lines.
