摘要:
A device includes, in a first region, a first conductive interconnect, an electrode structure on the first conductive interconnect, where the electrode structure includes a first conductive hydrogen barrier layer and a first conductive fill material. A trench capacitor including a ferroelectric material or a paraelectric material is on the electrode structure. A second dielectric includes an amorphous, greater than 90% film density hydrogen barrier material laterally surrounds the memory device. A via electrode including a second conductive hydrogen barrier material is on at least a portion of the memory device. A second region includes a conductive interconnect structure embedded within a less than 90% film density dielectric material.
