Patent ID: 8664704

Claim:
A device, 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; and a silicon nitride layer deposited over at least a portion of the barrier layer, wherein the upper portions of the first and second metal interconnects are formed over portions of top surfaces of the silicon nitride layer, wherein the substrate includes an insulating layer and a planarizing layer, and wherein the barrier layer and the dielectric layer are formed from the same dielectric material.
