Abstract:
A method of manufacturing a semiconductor device, comprising the steps of:forming an insulating film on a semiconductor substrate; forming an opening in said insulating film; forming a conductive layer on said insulating film including side and bottom surfaces of said opening; forming a coating layer on said conductive layer including an inner side of said opening; removing said coating layer and said conductive layer at a substantially same rate to align a top surface of said insulating film and surfaces of said coating layer and said conductive layer exposed at an opening end of said opening to be coplanar; under an atmosphere including CF4 and excess O2; removing a portion of said conductive layer located adjacent to the opening end of said opening, substantially leaving said insulating layer; and forming a second electrode portion, with a dielectric film interposed, on said first electrode portion.
