Abstract:
A method of manufacturing a semiconductor device comprising the sequential steps of:forming an interlayer insulating film on a semiconductor substrate;forming a first hole penetrating through said interlayer insulating film;forming a first layer including a semiconductor layer of a prescribed thickness so as to provide a second hole on side and bottom surfaces of said first hole and an upper surface of said interlayer insulating film;forming irregularities on a surface of said first layer;implanting silicon ions to an upper surface of said first layer formed at least on the upper surface of said interlayer insulating film;removing only said first layer formed on the upper surface of said interlayer insulating film and forming a first conductive layer;forming a dielectric film of a prescribed thickness to provide a third hole on the side and bottom surfaces of said second hole so as to cover at least a surface of said first conductive layer; andforming a second conductive layer to cover at least a surface of said dielectric film.
