Abstract:
1. A manufacturing method of a solid-state imaging apparatus comprising: bonding a first member and a second member, the first member having a first semiconductor substrate including a photoelectric conversion element and having a first wiring structure arranged on the first semiconductor substrate and the second member having a second semiconductor substrate including a transistor and having a second wiring structure arranged on the second semiconductor substrate, wherein the first member and the second member are bonded so that a pad for connection with an external terminal, the first wiring structure and the second wiring structure are positioned between the first semiconductor substrate and the second semiconductor substrate; thinning the first semiconductor substrate after the bonding of the first member and the second member, so that a thickness of the first semiconductor substrate is smaller than a thickness of the second semiconductor substrate; forming a micro lens layer on the first semiconductor substrate after the thinning of the first semiconductor substrate; and, exposing the pad on a side of the first semiconductor substrate after the forming of the micro lens layer, wherein the pad is connected to a circuit provided in the second member before the thinning of the first semiconductor substrate.
