Patent ID: 8461637

Claim:
A thin-film capacitor structure, comprising: a substrate; first and second metal interconnects that each comprise upper and lower portions; a thin-film capacitor attached to the substrate, the thin-film capacitor including a pyrochlore or perovskite material forming a dielectric layer between top and bottom electrode layers to form a single capacitor, each of the top and bottom electrode layers being contiguous and formed from a conductive thin-film material; a pyrochlore or perovskite alkali earth titanate hydrogen-gettering material forming a barrier layer deposited over a portion of the thin-film capacitor, wherein the barrier layer is formed over and in direct contact with a portion of a top surface of each of the lower portions of the first and second metal interconnects; a silicon nitride layer deposited over at least a portion of the barrier layer; wherein the first metal interconnect is in contact with the top electrode layer of the thin-film capacitor, wherein the first metal interconnect passes through the barrier layer and the silicon nitride layer to enable a direct electrical contact for the top electrode layer of the thin-film capacitor, and wherein the second metal interconnect is in contact with the bottom electrode layer of the thin-film capacitor, wherein the second metal interconnect passes through the barrier layer and the silicon nitride layer to enable a direct electrical contact for the bottom electrode layer of the thin-film capacitor.
