Abstract:
1. A semiconductor device comprising: a laminated structure body, which integrally has on a first region of a semiconductor substrate: a first portion where a first insulating film, a first conductor, a second insulating film, and a second conductor sequentially remain; a second portion where said first conductor and said second conductor are laminated on said semiconductor substrate; and a third portion where neither said second insulating film nor said second conductor remains on said semiconductor substrate; and a third insulating film, which covers said laminated structure body and includes one or more holes where one or more contact regions of said first conductor of said laminated structure body are exposed at one or more parts of said third portion, wherein said second conductor has a first opening corresponding to said third portion, and said second insulating film has a second opening that is larger than said first opening.
