Image sensor comprising a light shielding pattern with plural portions spaced apart on pixels of a sensor array area

An image sensor comprising:

• a substrate having a via hole;
• a photodiode arranged in a substrate, the photodiode laterally adjacent to the via hole in the substrate;
• a wiring line arranged under the substrate;
• a first conductive layer arranged in the via hole, the first conductive layer protruding through the via hole to the wiring line;
• and
• a second conductive layer electrically connected to the first conductive layer, and extending laterally towards the photodiode over the substrate, the second conductive layer covering the first conductive layer.

An image sensor comprising:

• a substrate having a via hole;
• a first plurality of photodiodes in the substrate;
• a second plurality of photodiodes in the substrate;
• a light shielding pattern on a backside of the substrate, the light shielding pattern covering the first plurality of photodiodes;
• a first conductive layer covering the backside of the substrate and extending laterally on a first level spaced apart from the backside of the substrate;
• and
• a second conductive layer including a vertical portion disposed in the via hole and an external portion extending laterally over the substrate, the external portion integrally connected to the vertical portion and having a pad portion,
• wherein the first conductive layer is interposed between the backside of the substrate and the external portion of the second conductive layer, and
• wherein the light shielding pattern includes a first portion extending laterally on the first level.
