ABSTRACT:
A stacked capacitor having a fin structure, and a method of fabrication. A first electrode with a fin structure is formed on a semiconductor substrate and a second electrode is formed over the first electrode and spaced therefrom by a dielectric film. The first electrode comprises an electrically conductive material, different from polycrystalline silicon, and a polycrystalline silicon film containing an impurity and covering the electrically conductive material. Thereby, the film thickness of the storage electrode of the fin capacitor is reduced and the corrugation of the surface of a memory device by the capacitor structure is mitigated.
