Abstract:
1. A method of fabricating an image sensor, comprising: forming an insulating interlayer including an electrically conductive line over a semiconductor substrate; forming a crystalline semiconductor layer including a photodiode; bonding the crystalline semiconductor layer and the semiconductor substrate together; leaving the photodiode on the semiconductor substrate by removing the crystalline semiconductor layer; forming a photodiode pattern connected to the electrically conductive line, the photodiode pattern separated per unit pixel by a gap area formed in the photodiode; forming a device isolation insulating layer on the insulating interlayer including the photodiode pattern and the gap area; forming a contact hole in the device isolation insulating layer to expose both of the photodiode pattern and a neighbor photodiode pattern; and forming a contact plug in the contact hole.
