  • Patent number: 8580598
    Abstract: Disclosed are an image sensor and a method of manufacturing the same. A metal wiring consisting of a lower metal wiring, an upper metal wiring, and a plug connecting the lower and upper metal wirings, in which the lower and upper metal wiring are made of a transparent conductive film pattern, is formed on a substrate with devices formed thereon, the devices including a photodiode and gate electrodes. Then, a passivation film, a color filter, and a microlens are sequentially formed on the metal wiring. All or a portion of the metal wiring is formed in a transparent conductive film pattern. As such, the metal wiring is formed on the photodiode.
    Type: Grant
