<p>According to one embodiment, a semiconductor device includes a stacked structure that is formed by laminating a first insulating film, first conductive layer, second insulating film and second conductive layer on a semiconductor substrate and in which the first and second conductive layers are connected with a via electrically, an interlayer insulating film formed to electrically separate the second conductive layer into a first region including a connecting portion with the first conductive layer and a second region that does not include the connecting portion, a first contact plug formed on the first region and a second contact plug formed on the second region. An isolation insulating film is buried in portions of the substrate, first insulating film and first conductive layer in one peripheral portion on the second region side of the stacked structure and the second contact plug is formed above the isolation insulating film.</p> |
