Abstract:
A method of manufacturing a semiconductor device comprising:forming a semiconductor on an insulating surface; forming a first insulating film on the semiconductor; forming a gate electrode on the first insulating film; doping the semiconductor with an impurity element that gives one conductivity type to form a first impurity region; doping the semiconductor with an impurity element that gives an opposite conductivity type using a mask formed on the semiconductor in order to form a second impurity region in the semiconductor; forming a second insulating film on the first and second impurity regions; forming contact holes in the second insulating film so that the contact holes reach the first and second impurity regions; forming a metal film so as to cover the contact holes; forming from the metal film wiring lines that are connected to the first and second impurity regions, and then removing a part of the metal film; and forming an amorphous semiconductor to be brought into contact with the first and second impurity regions where the metal film is removed, wherein the amorphous semiconductor is a photoelectric conversion layer of the photoelectric conversion element.
