Abstract:
A method and apparatus for forming an interconnect on a substrate is provided. A protective layer is formed on the substrate and in a via formed on the substrate wherein the protective layer is resistant to a halogen containing material. A barrier layer is formed on top of the protective layer. The barrier layer comprises a halogen containing material. A metal layer is deposited over the barrier layer. In another embodiment, the protective layer is selectively deposited in the via.

Claim (Index 11):
An interconnect on a substrate, the interconnect comprising:\n a first metal layer disposed on a substrate; a dielectric layer disposed on the first metal layer having a via therethrough and exposing a portion of a surface of the first metal layer; a protective layer in direct contact with an entire inner surface of the via, wherein the protective layer comprises ruthenium and is resistant to a halogen based precursor; a barrier layer in direct contact with the protective layer; a liner layer in direct contact with the barrier layer; and a second metal layer filling the via and being in direct contact with the liner layer and not in direct contact with the via, wherein a top surface of the dielectric layer is exposed and aligned with a top surface of the second metal layer.
