Patent ID: 7858431

Claim:
A method of manufacturing a photoelectric conversion device, comprising the steps of: providing a single crystal semiconductor substrate wherein the single crystal semiconductor substrate includes a fragile layer in a region at a depth of less than 1000 nm from one surface thereof and a first impurity semiconductor layer at the one surface side thereof and the single crystal semiconductor substrate is provided with a first electrode on the one surface side thereof; bonding the first electrode and a supporting substrate to each other; separating the single crystal semiconductor substrate using the fragile layer or vicinity of the fragile layer as a separation plane so that a first single crystal semiconductor layer is formed over the supporting substrate; forming an amorphous semiconductor layer on the first single crystal semiconductor layer wherein the first single crystal semiconductor layer is located between the amorphous semiconductor layer and the first electrode; performing heat treatment for solid phase growth of the amorphous semiconductor layer so that a second single crystal semiconductor layer is formed; forming a second impurity semiconductor layer having a conductivity type opposite to a conductivity type of the first impurity semiconductor layer at a surface side of the second single crystal semiconductor layer; and forming a second electrode over the second impurity semiconductor layer.
