Abstract

There are provided a semiconductor device a semiconductor device of capable of preventing the deterioration of characteristics of a capacitor of a stacked semiconductor memory device using a ferroelectric or high-dielectric film for the capacitor of the memory cell thereof, without preventing the scale down for high density integration, and a method for manufacturing the same. A semiconductor device according to the present invention includes: a first interlayer insulator film formed as one of a plurality of layers stacked on a semiconductor substrate; a capacitor formed on the first interlayer insulator film, the capacitor having a capacitor bottom electrode, a capacitor top electrode and a capacitor insulator film arranged between the capacitor bottom electrode and the capacitor top electrode; a second interlayer insulator film formed on the first interlayer insulator film, on which the capacitor is formed, the second interlayer insulator film having a surface which has the same level as that of a surface of the capacitor top electrode.
