Latest Patents

Kamijo holds a patent for a unique contact via structure that includes a barrier metal disc designed for low resistance contact. The patent describes a first metal interconnect structure embedded in a first dielectric material layer, which features a first metallic nitride liner containing a first conductive metal nitride and a first metallic fill material portion. Additionally, a second metal interconnect structure embedded in a second dielectric material layer overlies the first dielectric material layer. This second structure includes a pillar portion with a straight sidewall and a foot portion that protrudes laterally from the bottom periphery of the pillar. The foot portion is formed by oxidizing the top surface of the first metallic fill material, followed by the removal of the oxidized portion after creating a cavity through the second dielectric material layer. A second metallic nitride liner is then deposited in the volume from which the oxidized portion is removed.
