Abstract:
1. A method of manufacturing a semiconductor device, the method comprising: forming a first amorphous carbon film in a memory cell region of a semiconductor substrate and forming a first peripheral interlayer insulation film in a peripheral circuit region of the semiconductor substrate; forming a first insulating film so that the first amorphous carbon film and the first peripheral interlayer insulation film are covered with the first insulating film; removing a portion of the first insulating film that corresponds to a capacitor portion to be formed in the memory cell region so as to leave the remaining portion of the first insulating film which sandwiches the capacitor portion from at least opposite sides of the capacitor portion and which forms a first insulating film pattern continuously extending from the memory cell region to the peripheral circuit region; forming a capacitor in the capacitor portion from which the first insulating film has been removed; and then removing the first amorphous carbon film.
