Titanium-containing diffusion barrier for CMP removal rate enhancement and contamination reduction |
| abstract |
A semiconductor device is provided. The semiconductor device includes a dielectric layer over a substrate and a contact structure embedded in the dielectric layer. The contact structure includes a diffusion barrier contacting the dielectric layer, the diffusion barrier including a titanium (Ti)-containing alloy. The contact structure further includes a liner on the diffusion barrier, the liner including a noble metal. The contact structure further includes a conductive plug on the liner. |
