  • Publication number: 20190252247
    Abstract: A method includes forming a trench in a low-K dielectric layer, where the trench exposes an underlying contact area of a substrate. A first tantalum nitride (TaN) layer is conformally deposited within the trench, where the first TaN layer is deposited using atomic layer deposition (ALD) or chemical vapor deposition (CVD). A tantalum (Ta) layer is deposited on the first TaN layer conformally within the trench, where the Ta layer is deposited using physical vapor deposition (PVD). An electroplating process is performed to deposit a conductive layer over the Ta layer. A via is formed over the conductive layer, where forming the via includes depositing a second TaN layer within the via and in contact with the conductive layer.

  • Publication number: 20190027404
    Abstract: A barrier seed tool is configured to clean trenches in a first chamber, line the trenches with a diffusion barrier layer, and form a copper seed layer over the diffusion barrier layer in a second chamber. The clean chamber is configured to reduce overhangs in the copper seed layer by producing a plasma comprising positively and negatively charged ions including halogen ions, filtering the plasma to selectively exclude positively charged ions, and bombarding with the filtered plasma. The tool and related method can be used to reduce overhangs and improve subsequent gap fill while avoiding excessive damage to the dielectric matrix.
