Contact via structure including a barrier metal disc for low resistance contact and methods of making the same |
| abstract |
A first metal interconnect structure embedded in a first dielectric material layer includes a first metallic nitride liner containing a first conductive metal nitride and a first metallic fill material portion. A second metal interconnect structure embedded in a second dielectric material layer overlies the first dielectric material layer. The second metal interconnect structure includes a pillar portion having a straight sidewall and a foot portion adjoined to a bottom periphery of the pillar portion and laterally protruding from the bottom periphery of the pillar portion. The foot portion can be formed by oxidizing a top surface of the first metallic fill material portion, removing the oxidized portion after formation of a cavity through the second dielectric material layer, and depositing a second metallic nitride liner in a volume from which the oxidized portion is removed. |
