    摘要: An improved barrier stack for inhibiting diffusion of atoms or molecules, such as O2 is disclosed. The barrier stack is particularly useful in capacitor over plug structures to prevent plug oxidation which can adversely impact the reliability of the structures. The barrier stack includes first and second barrier layers. In one embodiment, the first barrier layer comprises first and second sub-barrier layers having mismatched grain boundaries. The sub-barrier layers are selected from, for example, Ir, Ru, Pd, Rh, or alloys thereof. By providing mismatched grain boundaries, the interface of the sub-barrier layers block the diffusion path of oxygen. To further enhance the barrier properties, the first barrier layer is passivated with O2 using, for example, a rapid thermal oxidation. The RTO forms a thin oxide layer on the surface of the first barrier layer. The oxide layer can advantageously promote mismatching of the grain boundaries of the first and second sub-barrier layer. The second barrier layer comprises a conductive oxide.

    摘要: An barrier stack for inhibiting diffusion of atoms or molecules, such as O2 is disclosed. The barrier slack includes first and second barrier layers formed from, for example, Ir, Ru, Pd, Rh, or alloys thereof. The first barrier layer is passivated with O2 using, for example, a rapid thermal oxidation (RTO) prior to formation of the second barrier layer. The RTO forms a thin oxide layer on the surface of the first barrier layer. The thin oxide layer passivates the grain boundaries of the first barrier layer as well as promoting mismatching of the grain boundaries of the first and second barrier layer.
