摘要:
An interconnect layout, an image sensor including the interconnect layout and a method for fabricating the image sensor each use a first electrically active physical interconnect layout pattern within an active pixel region and a second electrically active physical interconnect layout pattern spatially different than the first electrically active physical interconnect layout pattern within a dark pixel region. The second electrically active physical interconnect layout pattern includes at least one electrically active interconnect layer interposed between a light shield layer and a photosensor region aligned therebeneath, thus generally providing a higher wiring density. The higher wiring density within the second layout pattern provides that that the image sensor may be fabricated with enhanced manufacturing efficiency and a reduction of metallization levels.
