Patent ID: 8426231

Claim:
A method for manufacturing a semiconductor device including a photoelectric conversion element, comprising the steps of: irradiating a single crystal semiconductor substrate with an ion to form an embrittled region in the single crystal semiconductor substrate; bonding together the single crystal semiconductor substrate and a light-transmitting substrate with an insulating layer therebetween; separating the single crystal semiconductor substrate at the embrittled region to form a single crystal semiconductor layer over the light-transmitting substrate; processing the single crystal semiconductor layer to form an island-shaped single crystal semiconductor layer; selectively adding a first impurity element and a second impurity element to the island-shaped single crystal semiconductor layer to form a semiconductor region having an effect of photoelectric conversion, a semiconductor region having p-type conductivity, and a semiconductor region having n-type conductivity; forming a first electrode electrically connected to the semiconductor region having the p-type conductivity; and forming a second electrode electrically connected to the semiconductor region having the n-type conductivity.
