Claim:
1. A method of processing a substrate having an exposed copper surface, comprising: (a) providing a substrate having a contaminant material disposed on the copper surface to a substrate support within a hot wire chemical vapor deposition (HWCVD) chamber; (b) providing hydrogen (H (c) heating one or more filaments disposed in the HWCVD chamber to a temperature sufficient to dissociate the hydrogen (H (d) exposing the substrate to the dissociated hydrogen (H (e) cooling the one or more filaments to room temperature; (f) exposing the substrate in the HWCVD chamber to one or more chemical precursors to deposit a self-assembled monolayer atop the copper surface; and (g) depositing a second layer atop the substrate.
