Claim Text:
1. A semiconductor device comprising: a first semiconductor section including first wiring layers at one side thereof, the first semiconductor section further including a photodiode and at least one transistor; a second semiconductor section including second wiring layers at one side thereof, the first and second semiconductor sections being secured together with a bonding layer between the first and second wiring layers such that sides of the respective first and second wiring layers of the first and second semiconductor sections face each other; a first conductive material disposed in a first opening and extending through the first semiconductor section and the bonding layer to a first portion of the second wiring layers of the second semiconductor section such that the first wiring layers are in electrical communication with the second wiring layers; and a second conductive material disposed in a second opening other than the first opening, and extending through the first semiconductor section and the bonding layer to a second portion of the second wiring layers of the second semiconductor section such that the second wiring layers are in electrical communication with an external wire, wherein,
