Patent ID: 8008169

Claim:
A method for manufacturing a photoelectric conversion device comprising: forming a fragile layer in a region at a predetermined depth from one surface of a single crystal silicon substrate; forming a first impurity silicon layer on the one surface side in the single crystal silicon substrate; forming a first electrode over the first impurity silicon layer; disposing a supporting substrate and the single crystal silicon substrate so that one surface of the supporting substrate and the one surface of the single crystal silicon substrate face each other; bonding the single crystal silicon substrate with the supporting substrate with at least the first impurity silicon layer and the first electrode interposed therebetween; forming a single crystal silicon layer over the supporting substrate by separating the single crystal silicon substrate along the fragile layer or vicinity of the fragile layer with heat treatment; performing crystal defect repair treatment of the single crystal silicon layer; forming a silicon layer while epitaxially growing the silicon layer using the single crystal silicon layer as a seed layer by activating a source gas containing at least a silane-based gas with plasma generated at atmospheric pressure or near atmospheric pressure; and forming a second impurity silicon layer on a surface side in the single crystal silicon layer which is epitaxial grown.
