Abstract:
A method of manufacturing a semiconductor device, comprising the steps of:(a) forming a first insulating film above a semiconductor substrate having a first area and a second area surrounding said first area; (b) forming a first contact hole through said first insulating film in said first area, said first contact hole reaching said semiconductor substrate; (c) forming a second insulating film above said first insulating film; (d) forming a second contact hole through said second insulating film in said first area, said second contact hole reaching said first contact hole; (e) forming an electrode electrically connected to said semiconductor substrate in said second contact hole; (f) performing an etching process to expose a side wall of the electrode and reflect an outer peripheral shape of the side wall of said electrode upon an outer peripheral shape of a side wall of said second insulating film left in said second area surrounding said first area; (g) forming a dielectric film covering an exposed surface of said electrode; and (h) forming an opposing electrode on said dielectric films.
