Patent ID: 8487306

Claim:
A photoelectric conversion element comprising: a first conductive layer over a substrate; a first insulating layer over the first conductive layer; a first semiconductor layer over the first insulating layer; a second semiconductor layer over the first semiconductor layer; an impurity semiconductor layer over the second semiconductor layer; a second conductive layer over the impurity semiconductor layer; a second insulating layer over the second conductive layer; and a third conductive layer over the second insulating layer, wherein the third conductive layer includes a light-transmitting conductive material, wherein the second insulating layer includes a first opening, wherein the first semiconductor layer and the third conductive layer are connected to each other through the first opening, and wherein the first opening is surrounded by the second conductive layer, wherein the second insulating layer includes a second opening, and wherein the third conductive layer and a first wiring formed of a same material as the first conductive layer are connected to each other through the second opening.
