Abstract:
1. A method of manufacturing an image sensor, comprising: forming a transistor circuit and at least two lower interconnections on a substrate; forming a first upper interconnection on a first lower interconnection of the at least two lower interconnections; forming a first conductive-type conductive layer on at least one sidewall surface of the first upper interconnection; forming an intrinsic layer on the substrate including the first conductive-type conductive layer and the first upper interconnection; forming a trench in the intrinsic layer corresponding to a second lower interconnection of the at least two lower interconnections; forming a second conductive-type conductive layer on at least one sidewall surface of the trench; and forming a second upper interconnection in the trench having the second conductive-type conductive layer.
