Patent ID: 7445989

Claim:
A method of manufacturing a semiconductor device, said method comprising the steps of: forming a first insulating film over a first region of a semiconductor substrate; forming a first conductor over said first insulating film; forming a second insulating film over said first conductor; removing said second insulating film over a contact region of said first conductor, while leaving said first conductor in said contact region; after removing said second insulating film over the contact region, forming a second conductive film over said second insulating film; removing said second conductive film over the contact region of said first conductor to make the second conductive film into a second conductor; forming a third insulating film covering said second conductor; forming a first hole, which reaches said first conductor, in said third insulating film over the contact region; and forming a first conductive plug, which is electrically connected with said contact region of said first conductor, in said first hole.
