摘要：
An image sensor having a light receiving region and an optical black region includes a semiconductor substrate, an interconnection disposed on the semiconductor substrate and extending along an interface between the light receiving region and the optical black region, and via plugs disposed between the interconnection and the semiconductor substrate and serving as light shielding members at the interface. The via plugs are arranged in a zigzagging pattern along the interface.
