Latest Patents

Yuuki Kikuchi holds a patent for the "Integration of a self-forming barrier layer and a ruthenium metal liner in copper metallization." This patent describes methods for integrating conformal barrier layers and ruthenium (Ru) metal liners with copper (Cu) metallization in semiconductor manufacturing. According to the patent, the method includes providing a substrate containing a recessed feature, depositing a barrier layer in the recessed feature, and then depositing a Ru metal liner on the barrier layer. The substrate is subsequently exposed to an oxidation source gas to oxidize the barrier layer through the Ru metal liner. The process further involves filling the recessed feature with CuMn metal using an ionized physical vapor deposition (IPVD) process, heat-treating the substrate to diffuse manganese (Mn) from the CuMn metal to the oxidized barrier layer, and reacting the diffused Mn with the oxidized barrier layer to form a Mn-containing diffusion barrier. This innovative method enhances the performance and reliability of semiconductor devices.
