Abstract:
1. A semiconductor integrated capacitor, comprising: a substrate configured for fabricating the integrated capacitor; a first capacitor electrode formed on the substrate; a second capacitor electrode; a metal nitride conductive layer formed on the upper surface of the first capacitor electrode; and an oxidized dielectric layer adjacent to and derived proportionately from said metal nitride conductive layer, said oxidized dielectric layer and said metal nitride conductive layer residing between said first and second capacitor electrodes, wherein said metal nitride conductive layer is formed on the entire upper surface of the first capacitor electrode, and further comprising a dielectric layer formed on an upper surface of the metal nitride conductive layer and having at least one opening exposing a portion of the upper surface of the metal nitride layer, wherein said oxidized dielectric layer is adjacent to the at least one opening.
