Patent ID: 8772180

Claim:
A method of forming a structure, comprising: forming at least one trench in a dielectric material, which removes at least a portion of an upper surface of the dielectric material; depositing a conductive layer within the at least one trench; selectively depositing a sacrificial material on remaining portions of the upper surface of the dielectric material; providing a metal capping layer over the conductive layer, wherein the providing the metal capping layer results in a plurality of isolated deposits of a nucleated capping material being formed on the sacrificial material; and removing the sacrificial material with the plurality of isolated deposits of the nucleated capping material; wherein the removing of the sacrificial material with the plurality of isolated deposits of the nucleated capping material is one of: a UV assisted thermal composition process, followed by a solvent or water rinse; a thermal decomposition process followed by a solvent or water rinse; and a reducing plasma etch followed by a solvent or water rinse.
