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 16):
A method for improving the selectively depositing an etch stop layer, the method comprising:\n providing a substrate in a semiconductor processing chamber, the substrate having a dielectric on its surface; depositing copper onto the surface of the substrate by an electrofill process; chemically mechanically polishing the copper deposited by the electrofill process; flowing a plasma mixture of ammonia and nitrogen into the chamber to reduce the copper from a copper oxide to copper by removing organic contamination from the copper after chemically mechanically polishing the copper; flowing an oxygen plasma or oxygen into the chamber to oxidize the copper and allowing a monolayer of copper oxide to grow on a surface of the copper after reducing the copper; depositing thiol molecules that are selective only to the copper and allowing the thiol molecules to adsorb on the monolayer of copper oxide after allowing the monolayer to grow; and selectively depositing an etch stop layer over the dielectric layer.
