Abstract:
1. An image sensor, comprising: a first insulation interlayer structure on a first surface of a first substrate and having a multi-layered structure; a first wiring structure in the first insulation interlayer structure; a via contact plug extending from a second surface of the first substrate opposite to the first surface and penetrating the first substrate to be electrically connected to the first wiring structure; a plurality of color filters and a plurality of micro lenses stacked on the second surface in a first region of the first substrate; a second insulation interlayer structure on the second surface in a second region of the first substrate; a second wiring structure in the second insulation interlayer structure to be electrically connected to the via contact plug; a pad pattern electrically connected to the second wiring structure and having an upper surface through which an external electrical signal is applied; and a plurality of photodiodes between the first and second wiring structures in the first region of the first substrate and corresponding to each of the plurality of micro lenses.
