Selective deposition of metal over dielectric layers in a manner that minimizes of eliminates keyhole formation is provided. According to one embodiment, a dielectric target layer is formed over a substrate layer, wherein the target layer may be configured as allow conformal metal deposition, and a dielectric second layer is formed over the target layer, wherein the second layer may be configured to allow bottom-up metal deposition. An opening may then be formed in the second layer and metal may be selectively deposited over substrate layer. |
