Abstract:
1. A method comprising: providing a semiconductor substrate in a reaction chamber, wherein the semiconductor substrate includes a trench etched into a dielectric layer; pulsing an organometallic precursor containing a noble metal into the reaction chamber proximate to the semiconductor substrate; pulsing a disrupting plasma species into the reaction chamber proximate to the semiconductor substrate; pulsing a co-reactant species into the reaction chamber proximate to the semiconductor substrate, wherein the organometallic precursor, the disrupting plasma species, and the co-reactant species form an amorphous noble metal layer directly on the dielectric layer; placing the semiconductor substrate in an electroless plating bath; using an electroless plating process to deposit a copper seed layer onto the amorphous noble metal layer; and removing the semiconductor substrate from the plating bath.
