Patent ID: 6884692

Claim:
A method of providing a conductive material in an opening, the method comprising: providing a substrate assembly having at least one surface; providing an opening defined through the surface of the substrate assembly, wherein the opening is defined by at least one surface; forming at least one conductive material within the opening on the at least one surface defining the opening and on at least a portion of the substrate assembly surface; forming at least support material over the at least one conductive material, wherein forming at least support material comprises forming a support film over the at least one conductive material, wherein the opening is not completely filled by the support film; removing at least the support material outside of the opening to the at least one conductive material by planarization, wherein removing at least the support material outside the opening by planarization to the at least one conductive material comprises planarizing the support film outside the opening to the at least one conductive material; removing the at least one conductive material outside the opening, wherein removing the at least one conductive material outside the opening comprises removing the at least one conductive material outside the opening to at least the substrate assembly surface using at least one of a wet etch and dry etch; and removing the support material within the opening.
