Abstract:
1. A manufacturing method of a photoelectric conversion device, the method comprising: forming a first electrode over a substrate; forming a first semiconductor film having one conductivity over the first electrode; forming a second semiconductor film over the first semiconductor film; forming a third semiconductor film having a conductivity opposite to the one conductivity over the second semiconductor film; forming a first island-shaped semiconductor film, a second island-shaped semiconductor film over the first island-shaped semiconductor film, and a third island-shaped semiconductor film over the second island-shaped semiconductor film by removing a part of the first semiconductor film, the second semiconductor film, and the third semiconductor film to expose a part of the first electrode, wherein an end portion of the first electrode is covered by the first island-shaped semiconductor film; and removing a part of the second island-shaped semiconductor film and a part of the third island-shaped semiconductor film.
