Abstract:
A semiconductor device comprising:a semiconductor substrate;an isolating insulation film formed on an isolated region of a main surface of said semiconductor substrate;a pair of source/drain regions formed in an active region surrounded by the isolated region of the main surface of said semiconductor substrate;a gate electrode formed on a main surface of the active region of said semiconductor substrate through a gate insulating film;at least one interlayer insulating film formed to coat said isolating insulation film, said source/drain regions, and said gate electrode;a wiring layer formed by filling up a contact hole reaching said source/drain regions through an opening provided on said at least one interlayer insulating film;a capacitor connected to one of said pair of source/drain regions through said wiring layer; anda semiconductor film restraining a leakage current formed in said wiring layer so as not to contact said capacitor.
