Abstract:
1. A method of forming a metal layer over a patterned dielectric formed on a substrate, the method comprising: depositing a first material layer over said patterned dielectric in a gaseous deposition atmosphere including, at least temporarily, a catalytic material, wherein depositing said first material layer comprises establishing said gaseous deposition atmosphere by supplying one or more precursor gases, whereby at least one of said precursor gases includes said catalytic material; exposing said first material layer to a plating solution including ions of the metal to be deposited, wherein said catalytic material incorporated in said first material layer initiates a reaction to reduce metal ions and to form a metal layer on said first material layer; and controlling an amount of catalytic material incorporated into said first material layer by controlling at least one of a flow rate and a duration of supply of said catalytic material containing precursor gas.
