Abstract:
A method of improving selectivity of a metal in a selective deposition process. A pre-treatment process for the metal modifies the metal surface, and includes first reducing the metal to remove organic contamination from the metal followed by oxidation of the metal to allow a monolayer of a metal oxide to grow on the surface. This modification of the metal allows inhibitor molecules to adsorb on the metal oxide monolayer to improve selectivity.

Claim (Index 10):
A method for improving the selectivity of copper deposited by an electrofill process, the method comprising:\n providing a substrate in a semiconductor processing chamber, the substrate having copper lines formed in a dielectric layer; reducing the copper from a copper oxide to copper by removing organic contamination from the copper; oxidizing the copper by flowing O 2  or O 2  plasma into the semiconductor processing chamber and allowing a monolayer of copper oxide to thermally grow on a surface of the copper after reducing the copper; and depositing inhibitor molecules that are selective only to the copper and allowing the inhibitor molecules to adsorb on the monolayer of copper oxide after allowing the monolayer to grow.
