Abstract:
1. A method of manufacturing a photoelectric conversion device, comprising: forming a fragile layer in a region at a depth of less than 1000 nm from one surface of a single crystal semiconductor substrate, and forming a first impurity semiconductor layer, a first electrode, and an insulating layer on the one surface side; after bonding the insulating layer to a supporting substrate, separating the single crystal semiconductor substrate with the fragile layer or vicinity of the fragile layer used as a separation plane, thereby forming a first single crystal semiconductor layer over the supporting substrate; forming a second single crystal semiconductor layer by epitaxially growing a semiconductor layer on the first single crystal semiconductor layer by a plasma chemical vapor deposition method using a silane based gas and hydrogen with a flow rate 50 times or more that of the silane based gas as a source gas; forming a second impurity semiconductor layer having a conductivity type opposite to that of the first impurity semiconductor layer, over the second single crystal semiconductor layer; and forming a second electrode over the second impurity semiconductor layer.
