Patent number: 7842988Abstract: A noise generated by a constitution of widening an incident aperture of light of a photoelectric conversion element is reduced. In a manufacturing method of a photoelectric conversion device, first electroconductor arranged in a first hole arranged in the first interlayer insulation layer electrically connects a first semiconductor region to a gate electrode of an amplifying MOS transistor not through wirings included in a wiring layer. Moreover, a second electroconductor electrically connects a second semiconductor region different from the first semiconductor region to a wiring. In a constitution of that second electroconductor, a third electroconductor arranged in a second hole arranged in the first interlayer insulation layer and a fourth electroconductor arranged in a third hole arranged in the second interlayer insulation layer are stacked and electrically connected to each other.Type: GrantFiled: May 21, 2010Date of Patent: November 30, 2010Assignee: Canon Kabushiki KaishaInventors: Takashi Okagawa, Hiroaki Naruse, Hiroshi Yuzurihara, Shigeru Nishimura, Takeshi Aoki, Yuya Fujino
