Image sensor and method of manufacturing same

摘要

An image sensor includes a photodiode formed in substrate, an insulating interlayer structure formed on the substrate, a metal structure formed in the insulating interlayer structure, a dummy pattern formed on the insulating interlayer structure, and a light-shielding layer pattern enclosing the dummy pattern. The dummy pattern is at least partially overlapped by the metal structure and the light-shielding layer pattern is at least partially overlapped by the photodiode.
