Abstract:
A semiconductor device comprising: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; a contact interconnection layer formed in a contact hole formed in the first and second interlayer insulator films, the contact interconnection layer being electrically connected to a layer below the first interlayer insulator film; and a capacitor interconnection layer formed in a portion including a part or all of a top surface of the contact interconnection layer on the second interlayer insulator film and a part or all of a surface of the capacitor top electrode, the capacitor interconnection layer electrically connecting the capacitor top electrode with the contact interconnection layer.
