摘要 |
An image pickup apparatus of the present invention includes a plurality of photoelectric conversion elements disposed on a semiconductor substrate, a multi-layer wiring structure including a plurality of interlayer insulation films disposed above the semiconductor substrate, and a passiation layer disposed above the multi-layer wiring structure. A first insulation layer is disposed below the under surface of the passiation layer; a second insulation layer is disposed above the top surface of the passiation layer; and the refractive indices of the passiation layer and the first insulation layer differ from each other, and the refractive indices of the passiation layer and the second insulation layer differ from each other. Moreover, planarization processing is performed to at least one layer of the interlayer insulation films and the first insulation layer. Furthermore, a first anti-reflection film is disposed between the passiation layer and the first insulation layer, and a second anti-reflection film is disposed between the passiation layer and the second insulation layer.
