Abstract:
1. A method of manufacturing a solid state image pickup device having a plurality of pixels each including a photoelectric conversion region for converting light into a signal charge, and a plurality of wiring layers including first and second wiring layers, the method comprising steps of: forming the first wiring layer as a pattern by dividing a desired pattern into a plurality of patterns, connecting the divided patterns, and exposing the plurality of patterns; and forming the second wiring layer as a pattern by batch exposure processing, wherein a connecting position along which the divided patterns are connected is arranged in a pixel area in which the plurality of pixels are arranged, the wiring included in the first wiring layer is formed by a vertical direction wiring arranged in parallel with and not crossing the connecting position in the pixel area, and the wiring included in the second wiring layer is formed by a horizontal direction wiring crossing the connecting position in the pixel area.
