Patent ID: 8822235

Claim:
A method comprising: fabricating a capacitor on a substrate, the capacitor having a dielectric layer formed between first and second electrodes; depositing a reactive barrier layer over the capacitor; depositing a passivation layer over the reactive barrier layer; providing a first metal interconnect comprising an upper portion formed over a lower portion, wherein the first metal interconnect is in contact with the first electrode of the capacitor, wherein the first metal interconnect passes through the reactive barrier layer and the passivation layer to enable a direct electrical contact for the first electrode of the capacitor; and providing a second metal interconnect comprising an upper portion formed over a lower portion, wherein the second metal interconnect is in contact with the second electrode of the capacitor, wherein the second metal interconnect passes through the reactive barrier layer and the passivation layer to enable a direct electrical contact for the second electrode of the capacitor, wherein the depositing of the reactive barrier layer and the passivation layer are performed after the providing of the lower portions of the first and second metal interconnects.
