Patent ID: 7414297

Claim:
A capacitor construction, comprising: a semiconductor substrate supporting an electrical node and an electrically insulative material, the electrical node comprising metal, the electrically insulative material comprising borophosphosilicate glass; a plurality of structures spaced from one another by gaps; some of the gaps extending to the metal of the electrical node and some of the gaps extending to the borophosphosilicate glass of the electrically insulative material; a first electrically conductive material over the structures and gaps, the first electrically conductive material having a rugged topography imparted by the underlying structures and gaps; a dielectric material over the first electrically conductive material; a second electrically conductive material over the dielectric material; and wherein said structures consist essentially of metal silicide; wherein the first electrically conductive material comprises the metal of the metal silicide; and further comprising a nitrogen-comprising barrier layer between the first electrically conductive material and the dielectric material.
