摘要:
A capacitive element formed within a semiconductor device comprises an upper electrode, a capacitive insulating film containing an oxide and/or silicate of a transition metal element, and a lower electrode having a polycrystalline conductive film composed of a material having higher oxidation resistance than the transition metal element and an amorphous or microcrystalline conductive film formed below the polycrystalline conductive film.
